The network is not limited to the LAN, and may be a wide area network (WAN), a public switched telephone network (PSTN), the Internet, or the like.

The facsimile unit 116 is connected to the public switched telephone network (PSTN) and transmits facsimile data to or receives facsimile data from the PSTN. The facsimile unit 116 stores the received facsimile data in the HDD 115, converts it into print data that can be printed by the image forming unit 140, and outputs it to the image forming unit 140. As a result, the image forming unit 140 forms an image of the facsimile data received by the facsimile unit 116 on paper. Further, the facsimile unit 116 converts the data stored in the HDD 115 into facsimile data and transmits the data to the facsimile apparatus connected to the PSTN.

The motion sensor 117 detects a person within a predetermined range from the MFP 100 and outputs it to the CPU 111. In this embodiment, an infrared sensor is used as the motion sensor 117. If a person can be detected, a pyroelectric sensor may be used instead of the infrared sensor.

The external storage device 118 is controlled by the CPU 111, and is equipped with a CD-ROM 118A or a semiconductor memory. In the present embodiment, the CPU 111 describes an example of executing the program stored in the ROM 113, but the CPU 111 controls the external storage device 118 and reads the program for the CPU 111 to execute from the CD-ROM 118A. , The read program may be stored in the RAM 114 and executed.

The recording medium for storing the program to be executed by the CPU 111 is not limited to the CD-ROM 118A, and may be a medium such as a flexible disk, a cassette tape, an optical disk, an IC card, an optical card, or a semiconductor memory. Further, the CPU 111 downloads the program from the computer connected to the network and stores it in the HDD 115, or the computer connected to the network writes the program to the HDD 115 and loads the program stored in the HDD 115 into the RAM 114. Then, it may be executed by the CPU 111. The program referred to here includes not only a program that can be directly executed by the CPU 111, but also a source program, a compressed program, an encrypted program, and the like.

FIG. 5 is a schematic diagram illustrating the detection of a person by the MFP in the present embodiment. With reference to FIG. 4, the imaging range of the camera 119 when the MFP 100 is viewed from the side surface is shown by hatching. When the user A is located at a distance L1 from the MFP 100, the face of the user A is within the imaging range of the camera 119. On the other hand, when the user A is located at a distance L2 from the MFP 100, which is a position where the operation panel 160 of the MFP 100 can be operated, the face of the user A is within the imaging range of the camera 119.

Since the angle of view of the camera 119 is constant, the size of the subject becomes smaller as the distance from the MFP 100 increases. Further, as the distance from the MFP 100 increases, the imaging range of the camera 119 becomes wider, so that the imaging range may include a plurality of users. For example, in the image output by the camera 119, the size of the user A's face at a position where the user A is separated from the MFP 100 by a distance L1 is smaller than the size of the user A's face at a position separated from the MFP 100 by a distance L2.

The MFP 100 in the present embodiment authenticates the user based on the image output by the camera 119. However, the larger the size of the face in the image, the larger the amount of data, and therefore the higher the accuracy of authentication. Therefore, the degree of matching indicating the certainty that the user A is a registered user registered in advance becomes a smaller value as the distance from the MFP 100 increases. Specifically, the degree of matching determined based on the image output by the camera 119 when the user A is located at a distance L1 from the MFP 100 is determined by the camera when the user A is located at a distance L2 from the MFP 100. It is smaller than the degree of matching determined based on the image output by 119.

FIG. 6 is a diagram showing an example of the function of the CPU included in the MFP in the present embodiment. The function shown in FIG. 6 is a function formed in the CPU 111 by the CPU 111 included in the MFP 100 executing a custom screen display program stored in the ROM 113, the HDD 115, or the CD-ROM 118A. With reference to FIG. 6, the CPU 111 includes an image pickup control unit 51, a detection unit 53, a temporary request unit 55, a pre-authentication acquisition unit 57, an authentication request unit 59, a post-authentication acquisition unit 61, and a display control unit. 63 and an erasing unit 65 are included.

The image pickup control unit 51 controls the camera 119 so that the camera 119 takes an image. Since the camera 119 outputs a still image when the image is taken, the image pickup control unit 51 acquires the still image output by the camera 119. The image pickup control unit 51 causes the camera 119 to take an image in response to the detection of a person by the motion sensor 117. Further, the image pickup control unit 51 causes the camera 119 to take an image at predetermined time intervals while the person is detected by the motion sensor 117, and outputs the still image output by the camera 119 to the detection unit 53. The camera 119 may output a moving image. In this case, the image pickup control unit 51 may generate a still image from the moving images output by the camera 119 at predetermined time intervals, and output the still image to the detection unit 53.

The image pickup control unit 51 may analyze the moving image output by the camera 119, generate a still image when a person is detected, and output the still image to the detection unit 53. In this case, the motion sensor 117 is unnecessary.

The detection unit 53 detects a person in the still image in response to the input of the still image from the image pickup control unit 51. Specifically, the detection unit 53 extracts a portion of the still image in which a person is represented, and detects a person represented in the extracted portion. Hereinafter, the part in which a person is represented in a still image is referred to as a person part, and the person represented in the person part is referred to as a detected person. When the detection unit 53 detects the detected person, the detection unit 53 outputs the person portion to the provisional request unit 55 and the authentication request unit 59. The detection unit 53 may use pattern matching, although the technique for extracting a person portion from a still image is not limited. For example, a feature amount such as a shape and a color of each part of the face such as a face, eyes, nose, mouth, and eyebrows is determined in advance, and a person part is extracted from a still image by referring to the feature amount. Further, a still image captured and output by the camera 119 in a state where no person exists in the imaging range of the camera 119 is used as a reference image, and the difference between the still image output by the camera 119 and the reference image is used as a portion showing the person. It may be extracted. The detection unit 53 may detect a plurality of detected persons. When detecting a plurality of detected persons, the detection unit 53 outputs a plurality of person portions representing the plurality of detected persons to the provisional request unit 55 and the authentication request unit 59.

When one or more person parts are detected by the detection unit 53, the temporary request unit 55 transmits a temporary authentication request to the server 200 and outputs a temporary acquisition instruction to the pre-authentication acquisition unit 57 at predetermined time intervals. The temporary request unit 55 sends a temporary authentication request to the server 200 and outputs a temporary acquisition instruction to the pre-authentication acquisition unit 57 until the person portion is no longer detected or the operating user is authenticated.

When the authentication request unit 59 detects that the user can operate the operation unit 163, the authentication request unit 59 sends an authentication request to the server 200. For example, the authentication request unit 59 transmits an authentication request in response to the operation unit 163 accepting an arbitrary operation by the user. Specifically, the authentication request unit 59 sends an authentication request including a person portion extracted by the detection unit 53 based on the still image output by the camera 119 after the operation unit 163 receives an operation input by the user. Along with transmitting to 200, an acquisition instruction is output to the acquisition unit 61 after authentication. Since the server 200 that receives the authentication request transmits the authentication result, the authentication request unit 59 outputs a display instruction to the display control unit 63 when the authentication result indicates that the authentication is successful. The authentication result and display instruction include the user identification information of the authenticated operating user. The authentication request unit 59 does not output a display instruction to the display control unit 63 when the authentication result indicates an authentication failure.

FIG. 7 is a block diagram showing an example of the functions of the CPU included in the server according to the present embodiment. The function shown in FIG. 7 is a function formed in the CPU 201 by the CPU 201 included in the server 200 executing a custom data transmission program stored in the ROM 202, the HDD 204, or the CD-ROM 209. The custom data transmission program is part of the custom screen display program. With reference to FIG. 7, the CPU 201 included in the server 200 includes a provisional request reception unit 251, an authentication unit 253, a provisional determination unit 255, a custom data transmission unit 257, and an authentication request reception unit 259. The custom data transmission unit 257 includes a pre-authentication transmission unit 261 and a post-authentication transmission unit 265.

The authentication unit 253 determines which of the plurality of registered users in advance the detected person represented by the person portion is, based on the person portion represented by the person. The authentication unit 253 includes a comparison unit 271. The comparison unit 271 compares the person portion with the feature data defined for each of the plurality of registered users, and determines the degree of matching obtained as a result of the comparison. The degree of matching is a value indicating the certainty that the detected person is a registered user. The degree of matching indicates the degree to which the person portion has the characteristics specified by the characteristic data defined for the registered user. The degree of matching differs depending on the algorithm that authenticates the person by face, but regardless of which algorithm is used, as a result of comparison, there is a value indicating the certainty that the detected person is a registered user. Therefore, the value may be used as the degree of matching. Here, the feature data is an authentication image obtained by imaging a registered user. Therefore, the degree of matching indicates the degree to which the person portion and the authentication image are similar. The degree of matching becomes higher as the person portion and the authentication image are similar.

The provisional request reception unit 251 accepts the provisional authentication request when the communication unit 205 receives the provisional authentication request from any of the MFPs 100, 100A, and 100B. The provisional authentication request includes one or more person parts. Here, a case where a provisional authentication request is accepted from the MFP 100 will be described as an example. The provisional request receiving unit 251 outputs a provisional authentication instruction to the authentication unit 253 in response to receiving the provisional authentication request. The provisional authentication instruction includes one or more person parts included in the provisional authentication request. The MFP 100 transmits a provisional authentication request at predetermined time intervals while a person is present in the imaging range of the camera 119. Therefore, the temporary request reception unit 251 outputs a temporary authentication instruction to the authentication unit 253 every time the temporary authentication request is received from the MFP 100 at predetermined time intervals.

The authentication request receiving unit 259 receives the authentication request when the communication unit 205 receives the authentication request from any of the MFPs 100, 100A, and 100B. Here, a case where an authentication request is accepted from the MFP 100 will be described as an example. The authentication request includes one person part. The authentication request receiving unit 259 outputs an authentication instruction to the authentication unit 253 in response to receiving the authentication request. The authentication instruction includes one person part included in the authentication request. The MFP 100 transmits a temporary authentication request when the operation unit 163 accepts an operation by the user.

The authentication unit 253 authenticates the operating user who operates the MFP 100 based on the person portion included in the authentication instruction in response to the authentication instruction input from the authentication request receiving unit 259. Specifically, the authentication unit 253 determines that, among a plurality of registered users, there is a registered user whose matching degree with respect to the detected person represented by the person portion included in the authentication request is the threshold value TH1 or higher. The detected person is determined to be a registered user and authenticated as an operating user. When authenticating the operating user, the authentication unit 253 outputs the user identification information for identifying the authenticated operating user to the transmitting unit 265 after the authentication. The authentication unit 253 authenticates the operation user when there is no registered user whose matching degree with respect to the detected person represented in the person portion included in the authentication request is equal to or higher than the threshold value TH1 among the plurality of registered users. The error signal is output to the authentication request reception unit 259 without any problem. When an error signal is input after outputting the authentication instruction, the authentication request receiving unit 259 transmits an error signal indicating that the authentication has failed to the MFP 100 that has sent the authentication request.

When the provisional authentication instruction is input from the provisional request reception unit 251 at the stage before the operation user is authenticated, the authentication unit 253 of each of the plurality of registered users for each of the one or more person parts included in the provisional authentication instruction. The matching degree is determined, and the pair of the person part identification information for identifying the person part and the matching degree of each of the plurality of registered users is output to the provisional determination unit 255. When the provisional authentication instruction includes a plurality of person parts, the authentication unit 253 outputs a set of the person part identification information and the degree of matching of each of the plurality of registered users to the provisional determination unit 255 for each of the plurality of person parts.

The tentative determination unit 255 determines a registered user whose matching degree with respect to the detected person specified by the person partial identification information is the threshold value TH2 or more as the tentatively registered user for the detected person. However, the threshold value TH2 is smaller than the threshold value TH1. Therefore, the provisional determination unit 255 may determine two or more provisional registration users for one detection person. When determining the provisional registration user for the detected person, the provisional determination unit 255 outputs the provisional transmission instruction to the pre-authentication transmission unit 261. The provisional transmission instruction includes a set of user identification information for identifying the provisional registration user and the degree of matching of the provisional registration user with the detected person. When the tentative determination unit 255 determines a plurality of tentatively registered users for the detected person, the tentative transmission instruction includes as many pairs of user identification information and matching degree of each of the plurality of tentatively registered users as the number of tentatively registered users. ..

The provisional request reception unit 251 receives a provisional authentication request from the MFP 100 at predetermined time intervals. Therefore, the provisional determination unit 255 has a predetermined time until the provisional authentication instruction is no longer input at a predetermined time interval, or until the operation user is authenticated by the authentication unit 253 after the provisional authentication instruction is input. The interval determines the temporary registered user for the detected person.

The pre-authentication transmission unit 261 is a custom related to the user identification information included in the provisional transmission instruction and the provisionally registered user identified by the user identification information in response to the input of the provisional transmission instruction from the provisional determination unit 255. The portion of the data corresponding to the degree of matching and the degree of matching are transmitted to the apparatus that has sent the provisional authentication request, in this case, the MFP 100. In the pre-authentication transmission unit 261, provisional transmission instructions are input from the provisional determination unit 255 at predetermined time intervals. Therefore, different matching degrees may be input for the same user identification information at different times. The pre-authentication transmitter 261 is a portion of the custom data related to the provisionally registered user corresponding to the matching degree entered later when the matching degree entered later than the matching degree entered earlier is larger. Send the rest that has not been sent yet. If the degree of matching entered later is greater than the degree of matching entered earlier, it is highly likely that the temporary registration user is approaching the MFP100, and it is highly likely that the temporary registration user will operate the MFP100 next. As the temporary registration user approaches the MFP 100, the ratio of sending custom data related to the temporary registration user to the MFP 100 increases. Therefore, the amount of custom data transmitted after the temporary registration user starts the operation of the MFP 100 can be reduced, and the waiting time until the operation screen is displayed can be shortened. Further, the pre-authentication transmission unit 261 does not transmit the custom data related to the temporary registration user when the matching degree input after the matching degree is smaller than the matching degree input earlier.

Custom data consists of multiple operation screens. The part of the custom data corresponding to the degree of matching is the operation screen of the ratio corresponding to the degree of matching among the plurality of operation screens. For example, when the degree of matching is 50%, the portion of the custom data corresponding to the degree of matching is 50% of the operation screens among the plurality of operation screens included in the custom data. Therefore, when a plurality of temporary registration users are determined by the provisional determination unit 255, the pre-authentication transmission unit 261 transmits custom data at a higher rate as the provisional registration users have a higher degree of matching. When transmitting custom data, the pre-authentication transmission unit 261 authenticates a set of the user identification information of the temporarily registered user and the screen identification information for identifying the operation screen included in a part of the transmitted custom data. Output to the transmitter 265.

The pre-authentication transmission unit 261 transmits a number of operation screens corresponding to the degree of matching from among a plurality of operation screens defined by the custom data associated with the registered user. For example, when the number of operation screens defined by the custom data is 100, 50 operation screens are transmitted if the degree of matching is 50%. If the amount of data for each of the plurality of operation screens is different, the pre-authentication transmitter 261 will perform until the amount of data corresponding to the degree of matching is reached from among the plurality of operation screens defined by the custom data associated with the registered user. The operation screen may be transmitted. For example, when the total amount of data on the operation screen defined by the custom data is 10 MByte, if the degree of matching is 50%, the operation screen is transmitted until it reaches 5 Mbyte.

The pre-authentication transmission unit 261 includes a priority transmission unit 263. The priorities of the plurality of operation screens defined by the custom data are defined. The priority transmission unit 263 transmits a plurality of operation screens corresponding to the degree of agreement in order from the operation screen having the highest priority. When multiple operation screens defined by custom data are related to each other in a hierarchical structure, the operation screens belonging to the upper hierarchy among the multiple operation screens should have higher priority than the operation screens belonging to the lower hierarchy. You may. Further, the priority order may be set in advance for each of the plurality of operation screens belonging to the same layer. For example, in a menu screen in which transition buttons for transitioning to each of a plurality of operation screens are arranged, the priority of the arrangement of a plurality of transition buttons decreases from left to right, and the priority increases from top to bottom. It gets lower. Therefore, in the menu screen, the second operation screen arranged to the left of the first operation screen has a higher priority than the first operation screen, and the third operation screen arranged above the first operation screen. The operation screen of is set to have a higher priority than that of the first operation screen.

In addition, each of the plurality of operation screens defined by the custom data may be composed of a plurality of types of files. The priority transmission unit 263 transmits a file of a predetermined type among a plurality of types of files with priority over files of other types. For example, when the operation screen is composed of the first type file to the third type file, the second type file is transmitted after the first type file is transmitted on each of the plurality of operation screens defined by the custom data. Type of file is sent, and finally a third type of file is sent. The plurality of types of files are, for example, files having the extensions html, js, py, css, png, and jpg. You can set priorities for the file types. When the operation screen is composed of files with extensions html, js, py, css, png, jpg, the extensions are prioritized in the order of html, js, py, css, png, jpg. do it. In this case, if a file having at least the extension html is transmitted, the operation screen can be partially displayed in the device for receiving a part of the custom data, in this case, the MFP 100. Therefore, in the MFP 100, the operation screen can be displayed before transmitting the file with the extension having a lower priority than that of html. If the number of operation screens determined by the degree of matching or the number of operation screens determined by the amount of data is not an integer, the priority transmission unit 263 transmits all types of files for the operation screens except the last operation screen. Regarding the final operation screen, the files with the highest priority among the plurality of types of files may be transmitted in order.

When a plurality of pairs of user identification information and matching degree are input from the provisional determination unit 255, the priority transmission unit 263 has a high matching degree among a plurality of provisionally registered users specified by the plurality of user identification information. Give priority to temporary registered users and send some custom data. This is because the temporary registration user having a higher degree of matching may have a shorter distance from the MFP 100 that has sent the temporary authentication request, and is more likely to use the MFP 100. For example, the priority transmission unit 263 transmits in order from a part of the custom data related to the provisionally registered user having a high degree of matching.

After authentication, the transmission unit 265 receives the user identification information of the operation user input from the authentication unit 253, and the user identification information for identifying the operation user and the custom data corresponding to the operation user, which is before authentication, is the pre-authentication transmission unit. The remaining part other than the part transmitted by the transmission unit 261 is transmitted to the device that has transmitted the authentication request, here, the MFP100.

Returning to FIG. 6, the pre-authentication acquisition unit 57 includes the user identification information of the temporary registration user received from the server 200 by the communication unit 205 after the temporary acquisition instruction is input from the temporary request unit 55, and the custom data portion. , Match degree, and get. The pre-authentication acquisition unit 57 stores the user identification information of the temporary registration user received by the communication unit 205, the custom data portion, and the matching degree in association with each other in a predetermined custom area of the HDD 115.

The erasing unit 65 erases the custom data acquired by the pre-authentication acquisition unit 57. The custom data acquired by the pre-authentication acquisition unit 57 is stored in the custom area included in the HDD 115. The storage capacity of the custom area is predetermined. After the part of the custom data is stored by the pre-authentication acquisition unit 57, the erasing unit 65 erases the custom data stored in the custom area when the detected person is not detected by the detecting unit 53.

Further, the erasing unit 65 is at the stage where a part of the custom data is stored in the custom area of the HDD 115 by the pre-authentication acquisition unit 57, and if the capacity that can be stored in the custom area is smaller than the part of the custom data, the custom area Of the custom data stored in, the custom data associated with the minimum degree of matching is deleted. This makes it possible to secure an area for storing new custom data. The detective person corresponding to the custom data with the least degree of matching is most likely to be the longest distance from the MFP100 and is least likely to operate the MFP100 next, so the ones that are unlikely to be used are custom-made in order. The data can be erased.

The post-authentication acquisition unit 61 receives the user identification information of the operation user received from the server 200 by the communication unit 205 and the remaining portion of the custom data after the acquisition instruction is input from the authentication request unit 59. The post-authentication acquisition unit 61 associates the user identification information of the operating user received by the communication unit 205 with the remaining portion of the custom data, and stores it in a predetermined custom area of the HDD 115.

The display control unit 63 determines and determines the operation screen based on the custom data associated with the user identification information of the operation user included in the display instruction in response to the display instruction input from the authentication request unit 59. The operation screen is displayed on the display unit 161. At the time when the display instruction is input from the authentication request unit 59, all the custom data related to the operating user may not be acquired. In this case, a part of the custom data related to the operating user is acquired from the server 200 by the pre-authentication acquisition unit 57 and stored in the custom area of the HDD 115. The display control unit 63 displays the operation screen on the display unit 161 using a part of the custom data stored in the custom area of the HDD 115. Therefore, the time from when the operation user inputs an operation to the operation unit 163 until the operation screen is displayed on the display unit 161 can be shortened as much as possible.

FIG. 8 is a flowchart showing an example of the flow of the custom screen display process. The custom screen display process is a process executed by the CPU 111 when the CPU 111 included in the MFP 100 executes a custom screen display program stored in the ROM 113, HDD 115, or the CD-ROM 118A. With reference to FIG. 8, the CPU 111 included in the MFP 100 determines whether or not the user has been detected (step S01). If the motion sensor 117 detects the user, the process proceeds to step S02, otherwise the process proceeds to step S21. In step S21, the custom data stored in the custom area of the HDD 115 is erased, and the process returns to step S01. If the custom data stored in the custom area of the HDD 115 is not stored, the process is returned to step S01 as it is.

In step S02, the camera 119 is controlled to take an image, and the still image output by the camera 119 is acquired. In the next step S03, a person is detected from the still image, and the process proceeds to step S04. For example, a person part representing a person is extracted from a still image. The person part is, for example, a part in which a person's face is represented. Still images may contain multiple portraits. In this case, the CPU 111 extracts a plurality of person portions from the still image.

In step S04, the temporary authentication request is transmitted to the server 200, and the process proceeds to step S05. The provisional authentication request includes the person portion detected by step S03. The server 200 that receives the temporary authentication instruction transmits the custom data related to the temporary registered user. In step S05, the custom data transmitted by the server 200 is received. Since the server 200 transmits the user identification information of the temporary registration user and the degree of matching with the detected person represented by the detection portion together with the custom data, the server 200 receives them together. If the custom data is received, the process proceeds to step S06, otherwise the process proceeds to step S09.

In the next step S06, it is determined whether or not there is a free area for storing the custom data in the custom area of the HDD 115. If the amount of a part of the custom data received in step S05 is smaller than the free space of the custom area, the process proceeds to step S08, otherwise the process proceeds to step S07. In step S07, the custom data having the smallest degree of matching is deleted from the custom area, and the process returns to step S06. In step S08, a part of the custom data received in step S05 is stored in the custom area of the HDD 115 in association with the user identification information and the degree of matching of the temporary registration user received together with the custom data, and the process is performed in step S09. Proceed.

In step S09, it is determined whether or not the custom data has been received from the server 200. When determining a plurality of temporary registration users, the server 200 transmits custom data for each of the plurality of temporary registration users, and therefore determines whether or not the custom data of the next temporary registration user has been received. If the custom data of the next temporary registration user is received, the process returns to step S05, but if not, the process proceeds to step S10.

In step S10, it is determined whether or not the operation input by the user is detected. The operation here is an operation for the operation panel 160 or the automatic document transfer device 120. Specifically, when the touch panel 165 detects a position instructed by the user, and when the hard key unit 167 detects the pressing of any of a plurality of hard keys, the operation on the operation panel 160 is detected. Further, when the state detection sensor or the document detection sensor included in the automatic document transfer device 120 is turned on, the operation for the automatic document transfer device 120 is detected. If the operation is detected, the process proceeds to step S12, otherwise the process proceeds to step S11.

In step S11, it is determined whether or not a predetermined time has elapsed since the user was detected in step S01. If the predetermined time has not elapsed, the process is returned to step S10, but if the predetermined time has elapsed, the process is returned to step S01. When the process returns from step S11 to step S01, it is a case where a predetermined time elapses without accepting an operation by the user after the user is detected in step S01. In this case, it is highly possible that the temporary registration user is away from the MFP 100, and it is highly likely that the temporary registration user does not operate the MFP 100. Therefore, if the user is not detected in step S01, the process proceeds to step S21, and the custom data stored in the custom area is erased. When the process proceeds to step S12, it is a case of accepting an operation input to the MFP 100 by the user. In step S12, the camera 119 is controlled to take an image, and a still image output by the camera 119 is acquired. In the next step S13, as in step S03, a person is detected from the still image, and the process proceeds to step S14. In step S14, the authentication request is transmitted to the server 200, and the process proceeds to step S15. The authentication request includes a person portion representing the person detected by step S13 in the still image. The server 200 that receives the authentication instruction transmits the authentication result of the user and the rest of the custom data related to the operating user when authenticating the operating user. In step S15, it is determined whether or not the operating user has been authenticated based on the authentication result transmitted by the server 200. If the operation user is authenticated, the process proceeds to step S16, but if not, the process returns to step S01.

In step S16, reception of the remaining portion of the custom data transmitted by the server 200 is started, and the process proceeds to step S17. Since a part of the custom data for the operation user is stored in the custom area of the HDD 115, the process of acquiring the remaining part of the custom data for the operation user excluding the part stored in the custom area is started from the server 200. do.

In step S17, the operation screen is displayed on the display unit 161 according to the custom data for the operation user, and the process proceeds to step S18. In step S16, even when the reception of the remaining portion of the custom data is started and is being received, a part of the custom data is stored in the custom area of the HDD 115, so that a part of the custom data is stored in the operation screen. Can be displayed on the display unit 161. Therefore, it is possible to shorten the waiting time from the operation of the operation unit 163 by the operation user until the operation screen is displayed on the display unit 161.

In step S18, it is determined whether or not the operation input by the user has been accepted. The operation here is an operation for the operation panel 160. Specifically, when the touch panel 165 detects a position instructed by the user, the hard key unit 167 accepts an operation on the operation panel 160 when detecting the pressing of any of a plurality of hard keys. The standby state is set until the operation is accepted, and when the operation is accepted, the process proceeds to step S19. In step S19, it is determined whether or not the accepted operation is an operation instructing logout. If it is an operation instructing logout, the process ends, but if not, the process proceeds to step S20. In step S20, the process determined by the operation is executed, and the process is returned to step S18. The process defined by the operation includes, for example, a process of switching the operation screen.

FIG. 9 is a flowchart showing an example of the flow of the custom data transmission process. The custom data transmission process is a process executed by the CPU 201 when the CPU 201 included in the server 200 executes a custom data transmission program stored in the ROM 202, HDD 204, or CD-ROM 209. The custom data transmission program is part of the custom screen display program. With reference to FIG. 9, the CPU 201 determines whether or not the provisional authentication request has been received from any of the MFPs 100, 100A, and 100B. If the provisional authentication request is received, the process proceeds to step S202, but if not, the process proceeds to step S208.

In step S202, the device that has sent the provisional authentication request is specified, and the process proceeds to step S203. Here, a case where a provisional authentication request is received from the MFP 100 will be described as an example. In step S203, the provisional determination process is executed, and the process proceeds to step S204. The details of the tentative determination process will be described later, but it is a process of determining the tentatively registered user and the degree of matching.

In step S204, it is determined whether or not the provisional registration user has been determined as a result of executing the provisional determination process. If the temporary registration user is determined, the process proceeds to step S205, but if not, the process proceeds to step S208. In step S205, a temporary registration user to be processed is selected from the temporary registration users, and the process proceeds to step S206. Select from the temporarily registered users with the highest degree of matching. As a result, the custom data related to the temporarily registered user located near the MFP 100 can be acquired in order.

In step S206, the custom data partial transmission process is executed, and the process proceeds to step S207. The details of the custom data partial transmission process will be described later, but it is a process of transmitting the portion of the custom data related to the temporary registration user corresponding to the degree of matching to the device that has transmitted the temporary authentication request, here, the MFP 100. In step S207, it is determined whether or not there is a temporary registration user who is not selected as a processing target in step S205 among the temporary registration users determined in step S203. If there is an unselected temporary registration user, the process returns to step S205, and if such a temporary registration user does not exist, the process proceeds to step S208.

In step S208, it is determined whether or not the authentication request has been received from any of the MFPs 100, 100A, and 100B. If the authentication request is received, the process proceeds to step S209, but if not, the process returns to step S201. Here, a case where an authentication request is received from the MFP 100 will be described as an example. In step S209, the authentication process is executed, and the process proceeds to step S210. The details of the authentication process will be described later, but it is a process for authenticating the user who operates the MFP 100. In step S210, it is determined whether or not the operating user has been determined. When the user who operates the MFP 100 is authenticated, the user who operates the MFP 100 is determined as the operating user. If the operation user is determined, the process proceeds to step S211. If not, the process proceeds to step S213.

In step S211 the operation user is notified to the device that has sent the authentication request, in this case, the MFP 100, and the process proceeds to step S212. In step S212, the remaining portion of the custom data associated with the operating user is transmitted to the device that has sent the authentication request, in this case, the MFP 100, and the process returns to step S201. In step S213, the device that has sent the authentication request, here the MFP100, is notified of the error, and the process is returned to step S201.

FIG. 10 is a flowchart showing an example of the flow of the tentative determination process. The tentative determination process is a process executed in step S203 of the custom data transmission process. In step S201 before the provisional determination process is executed, the provisional authentication request is received from the MFP 100, and one or more person portions included in the provisional authentication request are specified. With reference to FIG. 10, one of the one or more person portions included in the provisional authentication request is selected as the processing target (step S31), and the processing proceeds to step S32.

In step S32, one registered user is selected as a processing target from a plurality of registered users, and the processing proceeds to step S33. In step S33, the person portion is compared with the characteristic data of the registered user, and the process proceeds to step S34. In step S34, the degree of agreement obtained as a result of the comparison is determined, and the process proceeds to step S35. In step S35, it is determined whether or not the degree of coincidence is equal to or higher than the threshold value TH2. If the degree of coincidence is equal to or higher than the threshold value TH2, the process proceeds to step S36, but if not, the process proceeds to step S38.

In step S36, the registered user selected in step S32 is determined as a temporary registered user for the detected person represented by the person portion selected in step S31, and the process proceeds to step S37. In step S37, the matching degree is associated with the provisionally registered user, and the process proceeds to step S38. In step S38, it is determined whether or not there is a registered user who is not selected as the processing target in step S32. If there is an unselected registered user, the process returns to step S32, but if it does not exist, the process proceeds to step S39. By executing steps S32 to S38, one or more provisionally registered users may be determined for one detected person.

In step S39, it is determined whether or not there is a person portion that is not selected as the processing target in step S31. If the unselected person portion exists, the process returns to step S31, but if it does not exist, the process returns to the custom data transmission process. As a result, one or more temporary registration users are determined for each of the one or more detection portions.

FIG. 11 is a flowchart showing an example of the flow of the custom data partial transmission process. The custom data partial transmission process is a process executed in step S206 of the custom data transmission process. With reference to FIG. 11, a temporary registration user is selected at a stage before the custom data partial transmission process is executed, and the degree of matching with the temporary registration user is determined. The transmission amount is determined with reference to FIG. 11 (step S41). The transmission amount is determined based on the degree of agreement. The degree of matching indicates the certainty that the detected person is a registered user, and here, the degree of matching is used as a probability and the unit is expressed as a percentage (%). When the unit of the transmission amount is the number of operation screens, the acquisition amount is the number obtained by multiplying the total number of operation screens determined by the custom data by the degree of agreement. For example, if 100 operation screens are defined by custom data and the degree of matching is 50%, the acquisition amount is determined to be 50.

In step S42, the operation screen having the highest priority is determined as the transmission target from among one or more operation screens defined by the custom data and not yet transmitted. Then, it is determined whether or not the acquisition amount is exceeded (step S43). When the operation screen to be transmitted is added to the operation screen that has already been transmitted, it is determined whether or not the transmission amount is exceeded. If the transmission amount is exceeded, the process is returned to the custom data transmission process, but if not, the process proceeds to step S44. In step S44, a part of the custom data including the operation screen determined as the transmission target is transmitted to the MFP 100 that has transmitted the temporary authentication request, and the process is returned to step S42.

FIG. 12 is a flowchart showing an example of the flow of the authentication process. The authentication process is a process executed in step S209 of the custom data transmission process. The authentication request is received before the authentication process is executed, and the person part included in the authentication request is specified. With reference to FIG. 12, the CPU 111 selects one registered user as a processing target from the plurality of registered users (step S51), and proceeds to the process in step S52. In step S52, the person portion included in the authentication request is compared with the authentication image of the registered user to be processed, and the process proceeds to step S53. In step S53, the degree of matching obtained as a result of the comparison is determined, and the process proceeds to step S54. In step S54, it is determined whether or not the degree of coincidence is equal to or higher than the threshold value TH1. If the degree of coincidence is equal to or higher than the threshold value TH1, the process proceeds to step S55, otherwise the process proceeds to step S56.

In step S56, it is determined whether or not there is a registered user who is not selected as the processing target in step S51 among the plurality of registered users. If there is an unselected registered user, the process returns to step S51, otherwise, the process returns to the custom data transmission process without determining the operating user. In step S55, the registered user selected in step S51 is determined as the operating user, and the process is returned to the custom screen display process.

<First modification>
In the information processing system 1 described above, the server 200 authenticates the user who operates the MFP 100. In the information processing system 1 in the modified example, the user is authenticated by each of the MFPs 100, 100A, and 100B. Hereinafter, the information processing system 1 in the first modification will be mainly described as being different from the above-mentioned information processing system 1.

FIG. 13 is a diagram showing an example of the function of the CPU included in the MFP in the first modification. The function shown in FIG. 13 differs from the function shown in FIG. 6 in that the provisional request unit 55 and the authentication request unit 59 have been deleted, and the pre-authentication acquisition unit 57 and the post-authentication acquisition unit 61 are the pre-authentication acquisition unit 57A. The points are changed to the post-certification acquisition unit 61A, and the authentication unit 71 and the provisional determination unit 73 are added. Since the other functions are shown in FIG. 6, the description thereof will not be repeated here.

Based on the person portion detected by the detection unit 53, the authentication unit 71 determines which of the plurality of registered users the detected person corresponding to the person portion is registered in advance. The authentication unit 71 includes a comparison unit 271. The comparison unit 271 compares the person portion with a plurality of feature data corresponding to each of the plurality of registered users, and determines the degree of matching obtained as a result of the comparison. The degree of matching is a value indicating the certainty that the detected person is a registered user. The degree of coincidence becomes higher as the person part and the feature data are similar.

When there is a registered user whose matching degree with respect to the detected person is the threshold value TH1 or more among the plurality of registered users, the authentication unit 71 determines the detected person as the registered user and authenticates the operating user. When authenticating an operating user, the authentication unit 71 outputs user identification information for identifying the authenticated operating user to the post-authentication acquisition unit 61A. The timing at which the authentication unit 71 authenticates the operating user is when the user is present at a position where the operation unit 163 can be operated. For example, the authentication unit 71 authenticates the user when the operation unit 163 accepts an arbitrary operation by the user. Specifically, the authentication unit 71 has a threshold value of the degree of matching with the detected person detected by the detection unit 53 based on the still image output by the camera 119 after the operation unit 163 receives an operation input by the user. If it is TH1 or higher, the detected person is determined to be a registered user, and the detected person is authenticated as an operating user.

The authentication unit 71 determines the degree of matching of each of the plurality of registered users for each of the one or more person parts detected by the detection unit 53 before authenticating the operating user, and identifies the person part. The partial identification information and the degree of matching of each of the plurality of registered users are output to the provisional determination unit 255. When one or more person parts are detected by the detection unit 53, the authentication unit 71 determines the person part identification information and the degree of matching of each of the plurality of registered users to the provisional determination unit 73 for each of the plurality of person parts. Output.

The tentative determination unit 73 determines a registered user whose matching degree with respect to the detected person specified by the person partial identification information is the threshold value TH2 or more as the tentatively registered user for the detected person. However, the threshold value TH2 is smaller than the threshold value TH1. Therefore, the provisional determination unit 73 may determine two or more provisional registration users for one detection person. When determining the temporary registration user for the detected person, the temporary determination unit 73 sets the set of the user identification information for identifying the temporary registration user and the degree of matching of the temporary registration user with the detected person in the pre-authentication acquisition unit 57A. Output. When a plurality of temporary registration users are determined for the detected person, the temporary determination unit 73 outputs a set of the user identification information and the degree of matching to the pre-authentication acquisition unit 57A for each of the plurality of temporary registration users.

The pre-authentication acquisition unit 57A sends a temporary transmission request to the server 200 in response to the input of the pair of the user identification information and the degree of matching from the temporary determination unit 73, and is identified by the user identification information from the server 200. Acquire the part corresponding to the degree of matching in the custom data corresponding to the temporarily registered user. The provisional transmission request includes the user identification information of the provisionally registered user and the degree of matching. The pre-authentication acquisition unit 57A associates the acquired custom data portion with the degree of matching and stores it in a predetermined custom area of the HDD 115. The pre-authentication acquisition unit 57A inputs a set of user identification information and a degree of agreement from the provisional determination unit 73 at predetermined time intervals. Therefore, different matching degrees may be input for the same user identification information at different times. If the match degree entered later than the match degree entered earlier is greater than the match degree entered earlier, the pre-authentication acquisition unit 57A is a match entered later in the custom data related to the provisionally registered user identified by the user identification information. Acquire the remaining part of the part corresponding to the degree that has not been acquired yet. If the matching degree input after the matching degree is smaller than the matching degree entered earlier, the pre-authentication acquisition unit 57A does not send the temporary transmission request to the server 200, and the temporary registered user is identified by the user identification information. Do not get custom data related to. The pre-authentication acquisition unit 57A is a custom related to the temporary registration user identified by the user identification information stored in the custom area of the HDD 115 when the matching degree input after the matching degree is smaller than the matching degree input earlier. The data may be erased. If the degree of matching is small, it is highly likely that the detecting person is away from the MFP 100, and it is unlikely that the MFP 100 will be operated next.

The post-authentication acquisition unit 61A sends a transmission request to the server 200 in response to input of the user identification information of the operation user authenticated by the authentication unit 71, and the custom related to the operation user authenticated by the server 200. Of the data, the remaining portion other than the portion acquired by the pre-authentication acquisition unit 57A is acquired. The transmission request includes the user identification information of the operating user. The post-authentication acquisition unit 61A stores the acquired custom data portion in a predetermined custom area of the HDD 115.

FIG. 14 is a block diagram showing an example of the function of the CPU included in the server in the first modification. With reference to FIG. 14, the function different from that shown in FIG. 7 is that the provisional request reception unit 251 and the authentication request reception unit 259 have been changed to the provisional transmission request reception unit 251A and the transmission request reception unit 259A, respectively, and authentication. The point is that the unit 253 and the tentative determination unit 255 have been deleted. Other functions are the same as those shown in FIG. 7, and the description thereof will not be repeated here.

When the communication unit 205 receives the temporary transmission request from any of the MFPs 100, 100A, and 100B, the temporary transmission request receiving unit 251A accepts the temporary transmission request. In response to receiving the temporary transmission instruction, the temporary transmission request reception unit 251A outputs a set of the user identification information of the temporary registration user included in the temporary transmission instruction and the degree of matching to the pre-authentication transmission unit 261.

When the communication unit 205 receives the transmission request from any of the MFPs 100, 100A, and 100B, the transmission request reception unit 259A accepts the transmission request. In response to receiving the transmission instruction, the transmission request reception unit 259A outputs the user identification information of the operation user included in the transmission instruction to the transmission unit 265 after authentication.

FIG. 15 is a flowchart showing an example of the flow of the custom screen display process in the first modification. With reference to FIG. 15, the difference from the custom screen display process shown in FIG. 8 is that step S03, step S04 and step S14 are changed to step S03A, step S04A and step S14A, respectively, after step S15. And step S15A is added. Since the other processes are the same as those shown in FIG. 8, the description will not be repeated here.

When a person is detected from the still image in step S03, the provisional determination process shown in FIG. 10 is executed in step S03A, and the process proceeds to step S04A. In step S04A, the temporary transmission request is transmitted to the server 200, and the process proceeds to step S05. The provisional transmission request includes a set of the user identification information of the provisionally registered user determined in step S03A and the degree of matching. The server 200 that receives the temporary transmission request transmits the portion of the custom data related to the temporary registration user that corresponds to the degree of matching. Therefore, in step S05, it is determined whether or not the custom data has been received from the server 200. If the custom data is received, the process proceeds to step S06, otherwise the process proceeds to step S09.

When a person is detected from the still image in step S13, the authentication process shown in FIG. 12 is executed in the next step S14A, and the process proceeds to step S15. In step S15, the process is branched according to the result of the authentication process. If the operation user is authenticated, the process proceeds to step S15A, and if not, the process returns to step S01. In step S15A, the transmission request is transmitted to the server 200, and the process proceeds to step S16. The transmission request includes the user identification information of the operating user authenticated in step S15.

FIG. 16 is a flowchart showing an example of the flow of the custom data transmission process in the first modification. With reference to FIG. 16, the CPU 201 included in the server 200 determines whether or not the provisional transmission request has been received from any of the MFPs 100, 100A, and 100B (step S201A). If the provisional transmission request is received, the process proceeds to step S202, but if not, the process proceeds to step S208A.

In step S202, the device that has transmitted the provisional transmission request is specified, and the process proceeds to step S205. The provisional transmission request includes a set of the user identification information of the provisionally registered user and the degree of matching. Here, a case where a provisional transmission request is received from the MFP 100 will be described as an example. In step S205, a temporary registration user to be processed is selected from the temporary registration users defined in the temporary transmission request, and the process proceeds to step S206. Select from the temporarily registered users with the highest degree of matching. As a result, custom data related to the temporarily registered user located near the MFP 100 can be transmitted in order.

In step S206, the custom data partial transmission process shown in FIG. 11 is executed, and the process proceeds to step S207. In step S207, it is determined whether or not there is a temporary registration user who is not selected as the processing target in step S205 among the temporary registration users defined in the temporary transmission request. If there is an unselected temporary registration user, the process returns to step S205, and if such a temporary registration user does not exist, the process proceeds to step S208A.

In step S208A, it is determined whether or not a transmission request has been received from any of the MFPs 100, 100A, and 100B. If the transmission request is received, the process proceeds to step S209A, but if not, the process returns to step S201A. Here, a case where a transmission request is received from the MFP 100 will be described as an example. In step S209A, the operation user identified by the user identification information included in the transmission authentication request is specified, and the process proceeds to step S212. In step S212, the remaining portion of the custom data associated with the operating user is transmitted to the device that has sent the authentication request, in this case, the MFP100, and the process returns to step S201A.

<Second modification>
In the above-described embodiment, an example in which face recognition is used for authentication of a user who operates each of the MFPs 100, 100A, and 100B has been described. In the second modification, voice authentication is used as the authentication method. In this case, each of the MFPs 100, 100A, and 100B is provided with a microphone for collecting sound, and a person is detected by extracting the user's voice from the sound collected by the microphone. Further, the server 200 stores a voiceprint as biometric information for authenticating a plurality of registered users.

Further, when the server 200 determines a plurality of temporary registration users by detecting the volume of the voice extracted from the sound collected by the microphone, the temporary registration user having a loud volume is prioritized and the temporary registration is performed. You may want to send some of the custom data related to the user. For example, a user who has a loud volume in the voice extracted from the sound collected by the MFP 100 is likely to have a shorter distance from the MFP 100 than other users, and is likely to operate the MFP 100 next. Therefore, by preferentially transmitting the custom data related to the user near the MFP 100 to the MFP 100, a part of the custom data can be stored in the MFP 100 at the stage when the user starts the operation. can.

Further, when the second modification is applied to the first modification, each of the MFPs 100, 100A, and 100B stores a voiceprint as biometric information for authenticating a plurality of registered users.

<Third modification example>
In the third modification, face authentication and voice authentication are used as the authentication method. In this case, each of the MFPs 100, 100A, and 100B is provided with a camera 119 and a microphone for collecting sound. The person part is extracted from the still image obtained by imaging with the camera 119, the user's voice is extracted from the first degree of matching with the temporarily registered user identified by face authentication, and the sound collected by the microphone, and the voice is voiced. Determines the second degree of match for the provisionally registered user identified by authentication. For the same temporary registered user, the degree of matching for the temporary registered user is determined based on the first degree of matching and the second degree of matching. For example, the first degree of agreement and the second degree of agreement and the sum are determined as the degree of agreement. Further, the degree of coincidence may be the average of the first degree of coincidence and the second degree of coincidence, or may be the product of the first degree of coincidence and the second degree of coincidence.

Since the degree of matching is determined by using two authentication methods, it is possible to improve the accuracy of identifying the user who exists at a position away from the MFP 100.

<Fourth modification>
The authentication method is not limited to face authentication and / or voice authentication as long as the biometric information of the person is used. For example, the authentication may be performed using a person's iris.

<Fifth variant>
In the above-described embodiment, authentication is performed using the biometric information of a person, and the degree of matching for a plurality of registered users is determined. Different methods may be used for authentication of the user who operates the MFP 100 and determination of the degree of matching using biometric information. For example, the degree of matching is determined using the biometric information of a person, and the user who operates the MFP 100 is authenticated by collating it with the password and ID set registered in advance as authentication information and the device identification information of the device carried by the user. You may try to do it. The device carried by the user may be a mobile information terminal, an IC card, or a magnetic card.

As described above, in the information processing system 1 of the present embodiment, the server 200 determines the degree of matching for each of the plurality of registered users based on the biometric information of the person detected by the MFP 100, and the MFP 100. When a person is detected in, the temporary registration user is determined based on the degree of matching determined for each of the plurality of registered users, and the temporary registration user is set before the operator who operates the MFP 100 is authenticated. The part of the related custom data according to the degree of matching is transmitted to the MFP 100. Therefore, in the MFP 100, when the operator is authenticated, before the operator is authenticated, based on the portion according to the degree of matching of the custom data related to the temporarily registered user received from the server 200. , The operation screen can be displayed. Therefore, in each of the MFPs 100, 100A, and 100B, the time from the authentication of the operator to the display of the operation screen can be shortened. Therefore, the operation screens for each of the plurality of users can be centrally managed by the server 200, and the response times for the plurality of MFPs 100, 100A, and 100B can be shortened.

Further, the server 200 determines a plurality of temporary registered users corresponding to a plurality of persons simultaneously detected by the MFP 100 from among the plurality of registered users. Therefore, custom data of a registered user who may operate the MFP 100 can be transmitted to the MFP 100 before the registered user operates the MFP 100.

Further, since the server 200 determines a plurality of temporary registered users corresponding to one person detected by the MFP 100 from among the plurality of registered users, the custom data of the registered users that may operate the MFP 100 can be obtained. It can be transmitted before the registered user operates the MFP 100.

Further, the server 200 or the MFP 100 compares the person portion included in the image acquired by the MFP 100 with the camera 119 with the feature data registered for authenticating each of the plurality of registered users, so that the authentication can be performed. Temporary registration users can be determined using the feature data to be used.

Further, since the server 200 or the MFP 100 compares the voice of the person included in the sound collected by the MFP 100 with the feature data registered in advance for authenticating each of the plurality of registered users, the feature data used for the authentication. Can be used to determine a temporary registered user.

Further, since the server 200 or the MFP 100 determines the matching degree based on the first matching degree determined by face authentication and the second matching degree determined by voice authentication, the accuracy of determining the temporary registration user is determined. Can be improved.

Further, when a plurality of temporary registration users are determined, the server 200 has custom data related to the temporary registration user whose voice included in the sound collected by the microphone of the MFP 100 is large among the plurality of temporary registration users. Priority is given to some parts. Since the temporary registration user with louder voice is more likely to be closer to the MFP 100, the response time can be shortened by giving priority to the custom data of the user who has a short time to use the MFP 100.

Further, when determining a plurality of temporary registration users, the server 200 precedes a part of the custom data related to the temporary registration user having a high degree of matching and a part of the custom data related to the other temporary registration user. Send to. Therefore, the temporary registration user having a high probability of being a registered user is given priority in transmitting the custom data, so that the response time of the temporary registration user having a high probability of being a registered user can be shortened.

Further, since the server 200 or the MFP 100 determines the degree of matching corresponding to the person at a predetermined time interval from the time when the biometric information is detected in the MFP 100 until the operator is authenticated, the larger the degree of matching, the more the custom data. You can increase the amount of data sent. Therefore, as the provisionally registered user approaches the MFP 100, the amount of custom data transmitted can be increased.

Further, since the server 200 preferentially transmits the operation screen having the higher priority among the plurality of operation screens defined by the custom data, the higher the priority is set, the higher the priority is to be used. Since the probability that the operation screen with high probability is displayed is high, the response time can be shortened.

It should be considered that the embodiments disclosed this time are exemplary in all respects and not restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
