In the drawing, the portable terminal 3 is described as a smartphone for convenience, but this is merely an example.

  FIG. 3 is a diagram schematically showing a use scene of the imaging apparatus 1 having the above configuration. For example, when a situation occurs in which a user of the imaging apparatus 1 wants to transmit captured image data to another person at a place where many people gather, such as a party, the imaging apparatus 1 is placed in the communicable area S. The image data is transmitted only to the portable terminal 3. In this case, the user of the imaging device 1 notifies the user of the portable terminal 3 of the communicable region S by irradiating the planar light region on the table with the illumination light generated by the illumination light generator 21. The user of the mobile terminal 3 sets the mobile terminal 3 in a state in which the mobile terminal 3 can wirelessly communicate with the imaging device 1 by moving the mobile terminal 3 to the illumination light irradiation region irradiated by the imaging device 1.

  FIG. 4 is a diagram showing the situation near the communicable region S in more detail. FIG. 4 shows a situation where the imaging apparatus 1 generates illumination light in a dimly lit room and illuminates the communicable area S so as to be distinguishable from the surrounding area. In the case shown in FIG. 4, the mobile terminals 3 a and 3 b are completely inside the communicable area S. On the other hand, only a part of the mobile terminal 3c is in the communicable area S. Further, the mobile terminal 3d does not enter the communicable area S at all. In this case, the users of the mobile terminals 3c and 3d may move the mobile terminals 3c and 3d inside the communicable area S in order to be able to perform wireless communication with the imaging device 1. In FIG. 4, the mobile terminals 3 a to 3 d have the same functional configuration as the mobile terminal 3. Also in the following description, when it is necessary to distinguish a plurality of mobile terminals 3, individual codes are assigned to the respective mobile terminals, such as “3a, 3b,...”.

  FIG. 5 is a diagram illustrating a change in display content on the display unit 22 when the imaging apparatus 1 transmits image data. The display unit 22 displays a live view so that communication with the imaging apparatus 1 can be determined. The visual field area displayed by the display unit 22 is included in the communicable area S. First, the display unit 22 adds a display that allows the mobile terminal 3 to distinguish between a terminal in a communicable state and a terminal in a communicable state. In FIG. 5A, an image (shaded) indicating that communication is not possible is superimposed on the mobile terminal 3d. On the other hand, FIG. 5B shows that all the mobile terminals 3a to 3d are in a communicable state.

  As shown in FIG. 4, the communicable area S is generally circular or elliptical. For this reason, the shape is different from the display screen of the rectangular display unit 22. In the first embodiment, for example, the communicable area S is large enough to pass the apex of the display unit 22. In this case, even if the boundary of the communicable region S (the boundary of the illumination light irradiation region) is unclear, the mobile terminal 3 displayed on the display screen of the display unit 22 can reliably communicate. It can be carried out.

  When the user of the imaging apparatus 1 starts transmitting image data after reaching the state shown in FIG. 5B, as shown in FIG. 5C, the transmitted image data D is transferred to the mobile terminals 3a to 3d. A transmission amount display bar B that displays the ratio of the data transmission amount at that time to the total data amount is displayed while being superimposed on the display. The image data D has light and shade according to the ratio of the transmitted data amount to the total data amount. The transmission amount display bar B is displayed white from the left by the amount of transmitted data. FIG. 5D is a diagram illustrating a state in which transmission of image data is completed. In FIG. 5D, the image data D is displayed darker than that in FIG. 5C, and the transmission amount display bar B is also all displayed in white.

  FIG. 6 is a diagram illustrating a change in display content on the display unit 42 when the mobile terminal 3 receives image data. In the portable terminal 3, the ratio of the data amount of the received image data to the total data amount is displayed. When the mobile terminal 3 starts reception, the ratio gradually increases from zero. FIG. 6A shows a state where 50% of the total data amount has been received. FIG. 6B shows a state in which the reception of image data is completed. After completing the reception of the image data, the display unit 42 displays the actually received image data (FIG. 6C).

  FIG. 7 is a flowchart illustrating an outline of processing performed by the imaging apparatus 1 having the above configuration. First, the control unit 2C initializes the imaging device 1 (step S101). In this initialization process, the control unit 2C performs, for example, a process of resetting a recording flag indicating that a moving image is being recorded to an off state.

  Subsequently, when a transmission button provided in the input unit 18 is operated (step S102: Yes), the imaging device 1 performs a data transmission process (step S103). Details of the data transmission process will be described later. After step S103, the imaging apparatus 1 returns to step S102.

In step S102, when the transmission button is not operated (step S102: No), the imaging apparatus 1 proceeds to step S104.
In step S104, when the setting button provided in the input unit 18 is operated (step S104: Yes), the imaging apparatus 1 displays a menu screen for changing the setting, and the imaging apparatus according to the user's selection operation. A condition setting process for setting various conditions 1 is executed (step S105). Details of the condition setting process will be described later. After step S105, the imaging apparatus 1 returns to step S102.
In step S104, when the setting button is not operated (step S104: No), the imaging apparatus 1 proceeds to step S106.

  When the setting button is not operated in step S104 (step S104: No), when the moving image button is operated (step S106: Yes), the control unit 2C inverts the recording flag indicating that the moving image is being recorded. (Step S107). Specifically, for example, when the recording flag is in an on state, the control unit 2C inverts the recording flag to an off state.

  Subsequently, the control unit 2C determines whether or not the recording flag recorded in the SDRAM 27 is on (step S108). When it is determined that the recording flag is off (step S108: No), the control unit 2C records the number of frames of the recorded moving image file and ends the generation of the moving image file (step S109). Subsequently, the control unit 2C transmits the shooting data (step S110).

  FIG. 8 is a flowchart showing an outline of the photographing data transmission process. First, the control unit 2C determines whether there is a mobile terminal 3 capable of communication (step S201). Specifically, the control unit 2C determines whether or not information related to the mobile terminal 3 included in the communicable area is set. As a result of the determination, if there is a mobile terminal 3 capable of communication (step S201: Yes), the control unit 2C determines whether or not an imaging data transmission instruction is input by the input unit 18. When an instruction to transmit shooting data is input by the input unit 18 (step S202: Yes), the control unit 2C transmits the shooting data to the mobile terminal 3 that has been set for communication via the wireless communication unit 20. (Step S203). Thereafter, the imaging apparatus 1 returns to the main routine.

  As a result of the determination by the control unit 2C in step S201, when there is no mobile terminal 3 capable of communication (step S201: No), the imaging device 1 returns to the main routine. In step S202, the imaging apparatus 1 also returns to the main routine even when an imaging data transmission instruction is not input by the input unit 18 (step S202: No).

  After the imaging data transmission process (step S110) described above, the imaging device 1 proceeds to step S112 described later.

  The case where it is determined in step S108 that the recording flag is in the on state (step S108: Yes) will be described. In this case, the control unit 2C generates a moving image file for recording the image data in time series on the recording medium 25 and stores it in the recording medium 25 (step S111). Thereafter, the imaging apparatus 1 proceeds to step S112.

  In step S106, when the moving image button is not operated (step S106: No), the imaging apparatus 1 proceeds to step S112.

  In step S112, the control unit 2C determines whether or not the recording flag recorded in the SDRAM 27 is on (step S112). If the result of determination is that the recording flag is off (step S112: No) and the 1st release signal is input from the release button (step S113: Yes), the control unit 2C exposes to the AE processing unit 15. The AE process for adjusting the AE is executed, and the AF process for adjusting the focus is executed by the AF processing unit 16 (step S114).

  Subsequently, the control unit 2C determines whether or not the power of the imaging device 1 is turned off by operating the power button (step S115). When the control unit 2C determines that the power of the imaging device 1 has been turned off (step S115: Yes), the imaging device 1 ends this process. On the other hand, when the control unit 2C determines that the power of the imaging device 1 is not turned off (step S115: No), the imaging device 1 returns to step S102.

  When the 1st release signal is not input from the release button (step S113: No), when the 2nd release signal is input from the release button (step S116: Yes), the imaging apparatus 1 performs shooting using the mechanical shutter (step S117).

  Subsequently, the image processing unit 14 performs predetermined image processing on the captured still image (step S118).

  Thereafter, the control unit 2C compresses the image data in the JPEG format by the image compression / decompression unit 17, and records the compressed image data on the recording medium 25 (step S119). In step S119, the control unit 2C causes the image data compressed by the image compression / decompression unit 17 in JPEG format to be associated with RAW data that has not been subjected to image processing by the image processing unit 14 and recorded on the recording medium 25. May be.

  Thereafter, the control unit 2C transmits the shooting data (step S120). The details of the photographing data transmission process are the same as in step S110 (see FIG. 8). After step S120, the imaging apparatus 1 proceeds to step S115.

  In step S116, when the 2nd release signal is not input from the release button (step S116: No), the controller 2C performs a data reception process (step S121).

  FIG. 9 is a flowchart showing details of the data reception process. First, the control unit 2C determines whether or not information related to the mobile terminal 3 to be communicated is set and the wireless communication unit 20 is about to receive data from the mobile terminal 3 (step S301). Here, whether the wireless communication unit 20 is about to receive data can be determined based on, for example, whether a data transmission request is received from the mobile terminal 3. As a result of the determination, when the wireless communication unit 20 is about to receive data (step S301: Yes), the control unit 2C causes the wireless communication unit 20 to receive data (step S302). On the other hand, as a result of the determination, when the wireless communication unit 20 is not trying to receive data (step S301: No), the imaging device 1 returns to the main routine.

  Thereafter, the control unit 2C causes the display unit 22 to perform confirmation display for allowing the user to confirm that the data has been received (step S303). Specifically, the control unit 2C displays the received data on the display unit 22 for a predetermined time (for example, 3 seconds). At this time, the display unit 22 may display an icon indicating that the received data is displayed. In addition, when reception is possible during moving image recording, reproduction may be started when a predetermined button such as an OK button is operated during display. Thereafter, the imaging apparatus 1 returns to the main routine.

  After the data reception process described above (step S121), the control unit 2C causes the AE processing unit 15 to execute an AE process for adjusting exposure (step S122). In this step S122, the AF processing unit 16 may further execute AF processing.

  Subsequently, the control unit 2 </ b> C drives the imaging unit 11 to perform imaging using the electronic shutter (step S <b> 123).

  Thereafter, the image processing unit 14 performs image processing based on the setting information of the imaging device 1 (step S124).

  The control unit 2C causes the display unit 22 to display a live view image corresponding to the image data processed by the image processing unit 14 (step S125).

  Thereafter, when the imaging apparatus 1 is recording a moving image (step S126: Yes), the control unit 2C compresses the image data by the image compression / decompression unit 17, and the compressed image data is created in the recording medium 25. The moving image file is recorded as a moving image (step S127). Thereafter, the imaging apparatus 1 proceeds to step S115. On the other hand, when the moving image is not being recorded in step S126 (step S126: No), the imaging device 1 proceeds to step S115.

  If the result of determination by the control unit 2C in step S112 is that the recording flag is off (step S112: Yes), the imaging apparatus 1 proceeds to step S122.

  Next, the outline of the data transmission process (step S103) of the main routine shown in FIG. 7 will be described with reference to the flowchart shown in FIG. First, the control unit 2C displays the recorded still image and moving image file as thumbnails on the display unit 22, and receives selection input of an image to be transmitted by the input unit 18 (step S401).

  Thereafter, the control unit 2C performs communication setting (step S402). Details of the communication setting process will be described later.

  Subsequently, the control unit 2C determines whether or not the mobile terminal 3 to be communicated has been set in the previous communication setting (step S403). If the mobile terminal 3 to be communicated is set as a result of the determination (step S403: Yes), the control unit 2C communicates the image data selected in step S401 to the wireless communication unit 20 for communication. Transmission to the terminal 3 is started (step S404). On the other hand, as a result of the determination, if the mobile terminal 3 for communication is not set (step S403: No), the imaging device 1 proceeds to step S408 described later.

  After starting data transmission, the control unit 2C displays an animation indicating that data transmission is in progress (step S405). At this time, the display unit 22 starts live view, and starts an animation that shows that transmission is being performed to the mobile terminal 3 displayed in the live view image. FIG. 5C can be given as a specific animation display example.

  When the data transmission is completed (step S406: Yes), the control unit 2C causes the display unit 22 to terminate the transmission animation and stop the live view (step S407). When the data transmission is not completed (step S406: No), the control unit 2C repeats the determination of step S406.

  Thereafter, the control unit 2C causes the display unit 22 to display a message for confirming whether or not to end the data transmission process. When a signal instructing termination is input by the input unit 18 (step S408: Yes), the imaging apparatus 1 ends the data transmission process and returns to the main routine. On the other hand, when the signal for instructing termination is not input by the input unit 18 (step S408: No), the imaging apparatus 1 returns to step S401.

  FIG. 11 is a flowchart showing an outline of the communication setting process (step S402) performed in the data transmission process described above. First, the control unit 2C causes the illumination light generator 21 to start generating illumination light (step S501). At this time, the control unit 2C transmits to the illumination light generation unit 21 a signal designating the amount of light to be irradiated and an irradiation angle together with a signal instructing generation of illumination light.

  Subsequently, the control unit 2C causes the display unit 22 to start a live view (step S502).

  Thereafter, the control unit 2C determines whether or not the focal length of the optical system of the imaging unit 11 has been changed (step S503). At this time, the control unit 2C makes a determination based on the operation of the zoom button or the zoom ring of the input unit 18. When the focal length of the optical system is changed (step S503: Yes), the region information generation unit 29 generates region information according to the focal length, and the generated region information is transmitted to the illumination light generation unit 21. Transmit (step S504). Here, the area information includes at least information related to the illumination angle of the illumination light of the illumination light generator 21. The irradiation angle is set so that the irradiation range becomes narrower as the focal length is longer, for example.

  Subsequently, when the release button of the input unit 18 is operated and a release signal is input (step S505: Yes), the imaging device 1 performs still image shooting (step S506).

  Thereafter, the detection unit 19 analyzes the captured image data (step S507). Specifically, the detection unit 19 analyzes the captured image data, and reads and acquires information related to communication only from the portable terminal 3 located inside the communicable region S irradiated with the illumination light. When the detection unit 19 determines whether or not the mobile terminal 3 is located in the communicable region S, the detection unit 19 may perform the determination based on the focal length of the optical system of the imaging unit 11 and the illumination angle information of the illumination light. Alternatively, the determination may be performed based on the luminance information of the image captured by the imaging unit 11.

  In step S507, the detection unit 19 may not read information from the mobile terminal 3 that is not focused for a certain period of time (that is, blurred for a certain period of time). The mobile terminal 3 that is not in focus for a certain time or more may be at an unexpected distance. For this reason, by not reading such information from the mobile terminal 3, it is possible to prevent communication with the mobile terminal 3 that is not intended by the user of the imaging device 1 from being set.

  In step S507, the detection unit 19 may read information related to communication using a plurality of pieces of image data acquired while a predetermined time has elapsed since the release button was pressed. In this case, for example, a color or a blinking pattern displayed on the display unit 42 of the mobile terminal 3 can be used.

  Subsequent to step S507, the control unit 2C performs communication setting with the portable terminal 3 by using the acquired information related to communication (step S508).

  Thereafter, the control unit 2C causes the display unit 22 to display information for prompting confirmation of the setting (setting confirmation information) (step S509). In step S509, an image capable of recognizing the mobile terminal 3 that has been set is superimposed on the live view image and displayed. For example, as shown in FIG. 5A, the mobile terminals 3a to 3c that have been set are displayed as live view images, while another image (shaded image) is displayed on the mobile terminal 3d that has not been set. ) May be superimposed and displayed. Note that when the communication setting is completed, the sound output unit 24 may output a sound notifying the completion of the setting. Also, the mobile terminal 3 may emit a sound or light when the communication setting is completed.

  Thereafter, when an instruction signal for ending communication setting is input by the input unit 18 (step S510: Yes), the control unit 2C stops the live view on the display unit 22 (step S511), and the illumination light generation unit 21 The generation of illumination light is stopped (step S512). Thereafter, the imaging apparatus 1 returns to the data transmission process. On the other hand, when the instruction signal for ending the communication setting is not input by the input unit 18 (step S510: No), the imaging device 1 returns to step S503.

  In the communication setting process described above, the portable terminal 3 that performs communication setting is limited to the illumination light irradiation range. Therefore, it is easy for the user of the imaging device 1 to specify the mobile terminal 3 that is desired to communicate. In addition, it is possible to prevent communication from being established with the mobile terminal 3 that is not intended by the user of the imaging apparatus 1, and it is possible to realize communication with higher safety.

  Further, in the communication setting process, the illumination angle of illumination light can be changed by changing the focal length, so that the user establishes communication only with the desired portable terminal 3 by changing the focal length by himself / herself. It becomes possible.

  Further, in the communication setting process, when the detection unit 19 analyzes the image data and reads the communication setting with the portable terminal 3, the communication setting of the portable terminal 3 that is blurred can be prevented from being read. Thereby, it is possible to prevent communication settings from being performed between the mobile terminal 3 that is too far away from the imaging device 1 and the mobile terminal 3 that is too close. Therefore, also in this sense, it is possible to prevent the establishment of communication with the portable terminal 3 that is not intended by the user of the imaging device 1, and it is possible to realize highly secure communication.

  Next, the outline of the condition setting process (step S105) of the main routine shown in FIG. 7 will be described with reference to the flowchart shown in FIG. First, the control unit 2C displays a setting menu on the display unit 22 (step S601). In the first embodiment, a case is described in which one of finish, recording mode, communication, and communication setting cancellation can be selected, but other items may be set.

  When the finish setting process is selected by the input unit 18 (step S602: Yes), the control unit 2C performs the finish setting process (step S603). Processes set in the finish setting process include, for example, natural, which is a process for finishing an image in a natural hue, vivid, which is a process for finishing an image vividly, flat, which is a process for finishing with an emphasis on the material properties of a subject, and image Monotone, etc., which is a process for finishing a monochrome tone.

  Thereafter, when the setting end operation is performed (step S604: Yes), the imaging apparatus 1 returns to the main routine. On the other hand, when the setting end operation is not performed (step S604: No), the imaging apparatus 1 returns to step S601.

  When the finish setting process is not selected in step S602 (step S602: No), the imaging device 1 proceeds to step S605.

  In step S605, when the recording mode setting process is selected by the input unit 18 (step S605: Yes), the control unit 2C performs the recording mode setting process (step S606). Here, the recording mode in the case of a still image is determined according to the type of still image to be recorded. The recording mode in the case of a moving image is determined according to the moving image compression format. Examples of the still image recording mode include a JPEG recording mode, a JPEG + RAW recording mode, and a RAW recording mode. Examples of the moving image recording mode include a Motion-JPEG mode and an MP4 (H.264) mode. Thereafter, the imaging apparatus 1 proceeds to step S604.

  If the recording mode setting process is not selected in step S605 (step S605: No), the imaging apparatus 1 proceeds to step S607.

  In step S607, when the communication setting process is selected by the input unit 18 (step S607: Yes), the control unit 2C specifies the mobile terminal 3 to communicate with and performs communication setting (step S608). This communication setting process is the same as the communication setting process described above (see FIG. 11). Thereafter, the imaging apparatus 1 proceeds to step S604.

  When the communication setting process is not selected in step S607 (step S607: No), the imaging device 1 proceeds to step S609.

  In step S609, when the communication setting cancellation process is selected by the input unit 18 (step S609: Yes), the control unit 2C cancels the communication setting (step S610). Thereafter, the imaging apparatus 1 proceeds to step S604. When the communication setting cancellation process is not selected in step S609 (step S609: No), the imaging device 1 proceeds to step S604.

  Next, a process performed when the mobile terminal 3 performs communication setting will be described. FIG. 13 is a flowchart illustrating an overview of processing performed when the mobile terminal 3 sets communication with the imaging device 1. First, the control unit 49 starts photographing (step S701), and starts counting of a timer in the control unit 49 so as to end the processing when a predetermined time has elapsed (step S702).

  Thereafter, the control unit 49 of the portable terminal 3 uses the image captured by the imaging unit 31 to irradiate the illumination light generation unit 21 of the imaging device 1 that is requesting information (communication setting data) necessary for communication setting. The illumination light to be detected is detected (step S703). Here, the detection of the emission of the illumination light may be determined from, for example, light of a specific wavelength, or may be detected from a blinking pattern when the illumination light is blinked.

  When the portable terminal 3 detects illumination light (step S704: Yes), the control unit 49 displays the communication setting data on the display unit 42 in order to cause the imaging device 1 to acquire the communication setting data (step S705). Specifically, the display unit 42 displays a barcode, a two-dimensional code, or the like obtained by coding the communication setting data. Instead of displaying the bar code or the two-dimensional code on the display unit 42, the information displayed on the display unit 42 is changed with time, and an animation display for displaying the entire communication setting data over a certain time is performed. You may do it.

  On the other hand, when the portable terminal 3 does not detect illumination light (step S704: No), the portable terminal 3 hides the communication setting data (step S706).

  After the process of step S705 or S706, when a certain time (for example, about 30 seconds) has elapsed since the control unit 49 started counting the timer (step S707: Yes), the control unit 49 stops the timer counting ( Step S708), stop of photographing (step S709), and non-display control (step S710) in the communication setting data display unit 42 are sequentially executed.

  When the control unit 49 starts counting the timer in step S707 and the predetermined time has not elapsed (step S707: No), the mobile terminal 3 returns to step S703.

  According to the first embodiment of the present invention described above, a communicable region that is a planar region in the imaging field of view of the imaging unit and is a planar region capable of wireless communication is shown in a visible manner. Region information is generated, a communication device located in a communicable region is detected based on image data captured by the imaging unit, and wireless communication is performed with the detected communication device, so communication is possible based on the region information. The area can be visually recognized by the user. Therefore, it is possible to easily set communication with the communication device by capturing an image of the communication device to be subjected to wireless communication.

  Further, according to the first embodiment, since the area where the communication device for performing wireless communication setting is to be arranged is illuminated with illumination light, the user of the communication device easily recognizes where the communication device should be arranged. be able to. Therefore, communication settings can be easily performed.

  In addition, according to the first embodiment, since it is possible to perform communication setting only with a communication device arranged in a planar communicable area, an image is taken when the distance to the imaging device is too far or too close. Communication is not set up with a communication device whose image is out of focus. Therefore, communication with higher safety can be realized.

  Further, according to the first embodiment, the user of the imaging apparatus can obtain satisfaction that the image data has been sent to the mobile terminal by transmitting the image data while looking at the display unit. The user can obtain satisfaction that he / she moved the mobile terminal within the communicable area illuminated by the illumination light and received image data from the imaging apparatus. Therefore, the memories of passing the images in the mutual exchange also remain in the user's memory, and the user's attachment to the images is further increased.

  FIG. 14 is a diagram illustrating another example of a change in display content on the display unit 22 when the imaging apparatus 1 transmits image data. In FIG. 14A, the display unit 22 superimposes and displays an image indicating that communication is not possible and image data that can be transmitted on the live view. FIG. 14A shows a case where the mobile terminals 3a to 3c are in a communicable state and the mobile terminal 3d is in a communicable state. On the other hand, FIG. 14B shows a case where all the mobile terminals 3a to 3d are in a communicable state.

  Thereafter, when the user of the imaging apparatus 1 touches and selects an image to be transmitted to the mobile terminals 3a to 3d (FIG. 14C), the selected image is enlarged and displayed on the display unit 22 (FIG. 14 ( d)). After that, when the imaging device 1 starts transmitting image data to the mobile terminal 3 in a communicable state, the display unit 22 indicates that the imaging device 1 is transmitting image data to the mobile terminals 3a to 3d. Is schematically displayed as a moving image (FIG. 14E). In FIG. 14 (e), the transmitted image is displayed as a moving image like a flag fluttering in the wind.

  When the transmission of the image data is completed, the display unit 22 superimposes and displays the images transmitted to the mobile terminals 3a to 3d as shown in FIG. In addition, when transmission of image data is completed, you may make it display the received image on the display part 42 of portable terminal 3a-3d. In this case, in FIG. 14F, an image displayed at the position of the display unit 42 of the mobile terminals 3a to 3d can be a live view image.

  In the first embodiment, instead of illuminating the illumination light and clearly indicating the communicable area, for example, the light may be irradiated while circling the boundary of the communicable area with light having a small spot diameter.

The detection unit 52 of the imaging device 5 includes an identification information reading unit 521 that reads identification information displayed on the mobile terminal 7 that is a communication target. Further, the flash memory 53 of the imaging device 5 includes a communication information storage unit 531 that stores information related to communication including setting information of a communicable area. The configuration of the imaging device 5 other than these is the same as the configuration of the imaging device 1.

  FIG. 16 is a block diagram illustrating a functional configuration of the mobile terminal 7. The portable terminal 7 shown in the figure does not have an illumination light generator. Further, the flash memory 71 of the mobile terminal 7 is used for communication between the identification information storage unit 711 that stores the identification information displayed on the display unit 42, the communication information storage unit 712 that stores information related to communication, and the imaging device 5.

It is. Other configurations of the mobile terminal 7 are the same as the configuration of the mobile terminal 3. Note that an LED may be provided on the surface of the mobile terminal 7 and the blinking pattern of the LED may be used as identification information.

FIG. 17 is a diagram illustrating a situation in the vicinity of the communicable area S <b> 1 of the imaging device 5. In the second embodiment, the display unit 42 of the mobile terminal 7 displays information as to whether or not the mobile terminal 7 is in the communicable area S1 of the imaging device 5.
In FIG. 17, since the mobile terminal 7a is inside the communicable area S1, the display unit 42 is bright.
On the other hand, since the mobile terminals 7b to 7d are placed across the boundary of the communicable area S1, the part inside the communicable area S1 is displayed in gray on the display unit 42. Therefore, the boundaries of the communicable region S1 are schematically displayed on the display units 42 of the mobile terminals 7b to 7d in a manner that is visible to the user.
Further, since the mobile terminal 7e is placed outside the communicable area S1, the display unit 42 remains dark.

  Thus, in this Embodiment 2, since the display part 42 of the portable terminal 7 displays the information about communicable area | region S1, the user of the portable terminal 7 has the own portable terminal 7 in communicable area | region S1. On the other hand, it can be easily discriminated by visual inspection what position it is placed.

FIG. 18 is a diagram illustrating a more detailed screen transition example on the display unit 42 of the mobile terminal 7.
FIG. 18A is a diagram showing a display example on the display unit 42 when located outside the communicable region S1. In FIG. 18A, all areas except for the display areas of the identification information Id1 to Id4 are masked in black, indicating that the display unit 42 is not located in the communicable area S1.
FIG. 18B is a diagram illustrating a display example on the display unit 42 when the display unit 42 is located across the boundary of the communicable region S1. In FIG. 18B, the boundary K of the communicable area is schematically shown on the display unit 42, and the outside of the area is masked black, while the inside of the area is displayed in gray.
FIG. 18C is a diagram illustrating a display example on the display unit 42 when the entire display unit 42 is located inside the communicable region S1.

  As shown in FIG. 18, identification information Id1, Id2, Id3, and Id4 made up of two-dimensional codes are displayed at the four corners of the display unit. The identification information Id1 to Id4 is information related to the size and shape of the portable terminal 7 and the display unit 42, information about the display position of the identification information on the display unit 42, identification information, in addition to information such as an ID unique to the portable terminal 7. Information on the distance between the center of the display position and the representative position (for example, the center) of the mobile terminal 7, information on the orientation of the display screen of the display unit 42 (vertical and horizontal directions if the display screen is rectangular), etc. Is recorded. For this reason, the patterns of the identification information Id1 to Id4 are slightly different from each other.

  FIG. 19 is a sequence diagram illustrating an outline of communication performed by the communication system according to the second embodiment. The imaging device 5 transmits the feedback signal generated by the region information generation unit 51 periodically and without specifying the transmission destination (indiscriminately). This feedback signal includes information such as a specific channel, a frequency band, and a communication method (protocol) as setting information for the communicable area. The feedback signal also includes identification information and position information read by the identification information reading unit 521 using the live view image. Hereinafter, such communication is referred to as feedback communication.

  Thereafter, when a release signal is input by the input unit 18, the imaging device 5 transmits information for communication (including communication setting information such as a password) to the mobile terminal 7 in the communicable area. At the same time, a signal (communication information transmission request) for requesting transmission of information necessary for communication with the mobile terminal 7 is transmitted. The mobile terminal 7 that has received these signals from the imaging device 5 transmits the requested communication information to the imaging device 5. In this way, the imaging device 5 sets and establishes communication with the mobile terminal 7 in the communicable area S1.

  FIG. 20 is a flowchart illustrating an outline of the communication setting process performed by the imaging device 5. The control unit 2C causes the display unit 22 to start live view (step S801). FIG. 21 is a diagram illustrating a display example on the display unit 22 of the communicable area in the live view. As shown in FIG. 21, the display unit 22 displays a communicable area 221 and an incommunicable area 222 in an identifiable manner. In FIG. 21, captured images are omitted. When setting the communicable area 221, for example, the relationship between the average height of a person and the average value of the height of the table surface on which the portable terminal 7 is placed is stored in the communication information storage unit 531 in advance. Alternatively, it may be set using this relationship.

  Thereafter, the control unit 2C starts feedback communication (step S802). In feedback communication, the region information generation unit 51 sets a specific channel, frequency band, communication method (protocol), and the like, and generates a trigger signal including this setting information. The control unit 2C transmits the trigger signal generated by the region information generation unit 51 indiscriminately and regularly via the wireless communication unit 20.

  Subsequently, the detection unit 52 captures a live view (step S803), analyzes the captured image data, and determines whether or not the portable terminal 7 exists in the image (step S804). In step S804, the identification information reading unit 521 reads the identification information of the mobile terminal 7 in the image. The control unit 2C determines the distance between the center of gravity of the portable terminal 7 and a predetermined position (for example, the center point) of the communicable region based on the read identification information and the communicable region information stored in the communication information storage unit 531. Is calculated, and it is determined whether or not the mobile terminal 7 is present in the communicable area.

  FIG. 22 is a diagram illustrating a screen transition example in the display unit 22 during the determination by the imaging device 5. After the mobile terminal 7 is arranged as shown in FIG. 22A, the detection unit 19 determines the presence or absence of the mobile terminal 7 in the communicable area. FIG. 22B is a diagram illustrating a screen display example on the display unit 22 being determined by the detection unit 19. As shown in FIG. 22 (b), a broken-line frame F1 is superimposed and displayed on the mobile terminal 7 being determined, while a solid-line frame F2 is superimposed and displayed on the mobile terminal 7 that has been determined. The FIG. 22C shows a screen display example on the display unit 22 when the determination of all the mobile terminals 7 in all the communicable areas is completed.

  Subsequently, the control unit 2C transmits the feedback signal including the identification information and position information of the mobile terminal 7 acquired in step S804 via the wireless communication unit 20 in addition to the communication setting area information without specifying the other party. It transmits to discrimination (step S805).

  Thereafter, when a release signal is input by the input unit 18 (step S806: Yes), the imaging device 5 transmits information necessary for communication to the mobile terminal 7 recognized as being in the communicable area. The communication information is exchanged by transmitting a signal requesting transmission of information necessary for communication to the mobile terminal 7 (step S807). Here, a release signal is used as a communication setting trigger. However, a touch signal input by touching the touch panel 181 may be used as a communication setting trigger. In step S806, when the release signal is not input by the input unit 18 (step S806: No), the imaging device 5 proceeds to step S810 to be described later.

  Subsequently, the control unit 2C sets and establishes communication using the exchanged information (step S808). Thereafter, the control unit 2C causes the display unit 22 to display setting confirmation information for prompting the user to confirm the setting (step S809).

  When the communication setting end instruction is input (step S810: Yes), the control unit 2C ends the feedback communication (step S811), and causes the display unit 22 to stop the live view (step S812). Thereafter, the imaging device 5 returns to the main routine. On the other hand, when the communication setting end instruction image is not input (step S810: No), the imaging device 5 returns to step S803.

  FIG. 23 is a flowchart illustrating an overview of the communication setting process performed by the mobile terminal 7. First, the control unit 49 starts feedback communication (step S901). Specifically, the control unit 49 calls and activates an application for feedback communication from the application storage unit 713. Thereafter, the control unit 49 starts counting the timer (step S902).

  Subsequently, the control unit 49 displays the identification information (two-dimensional code) stored in the identification information storage unit 711 on the display unit 42 (step S903).

  Thereafter, the wireless communication unit 40 receives feedback of identification information, position information, and communication setting information from the imaging device 5 (step S904). In this case, when there is identification information (self-identification information) of the mobile terminal 7 itself in the feedback received data (step S905: Yes), the control unit 49 displays based on the distance from the imaging device 5 and the communicable area information. The area display in the unit 42 is updated (step S906). The area display is, for example, as shown in FIG. 18B, and the boundary K of the communicable area is clearly indicated. On the other hand, when there is no self identification information in the data received by feedback (step S905: No), the control unit 49 ends the area display on the display unit 42 and displays only the identification information (step S907).

  After step S906 or S907, when the wireless communication unit 40 receives communication information and a communication information transmission request from the imaging device 5 and performs communication information exchange (step S908: Yes), the wireless communication unit 40 Under the control, the requested communication information is transmitted to the imaging device 5 (step S909). On the other hand, when the wireless communication unit 40 does not receive communication information or a communication information transmission request from the imaging device 5 and does not exchange communication information with the imaging device 5 (step S908: No), the mobile terminal 7 The process proceeds to S910.

  When the control unit 49 starts counting the timer in step S910 and a certain time (for example, about 30 seconds) has elapsed (step S910: Yes), the control unit 49 ends the display of the identification information on the display unit 42. (Step S911), the timer count is stopped (Step S912), and the feedback communication is terminated (Step S913).

  If the fixed time has not elapsed since the timer started counting in step S910 (step S910: No), the portable terminal 7 returns to step S904.

  According to the second embodiment of the present invention described above, a communicable region that is a planar region within the imaging field of view of the imaging unit and is a planar region capable of wireless communication is shown in a visible manner. Region information is generated, a communication device located in a communicable region is detected based on image data captured by the imaging unit, and wireless communication is performed with the detected communication device, so communication is possible based on the region information. The area can be visually recognized by the user. Therefore, communication with the device can be easily set by capturing an image of the device to be subjected to wireless communication.

  In addition, according to the second embodiment, since the mobile terminal has a function of displaying an area where a communication device for performing wireless communication setting is to be arranged, the user of the communication device should place the communication device anywhere. It is possible to easily recognize whether it is good. Therefore, communication settings can be easily performed.

  In addition, according to the second embodiment, communication settings can be made only with a communication device arranged in a planar communicable area, so that an image is taken when the distance to the imaging device is too far or too close. Communication is not set up with a communication device whose image is out of focus. Therefore, communication with higher safety can be realized.

  Further, according to the second embodiment, the user of the imaging apparatus can obtain satisfaction that the image data has been transmitted to the mobile terminal by transmitting the image data while looking at the display unit. The user can obtain satisfaction that the user has moved the mobile terminal based on the boundary information of the communicable area schematically displayed on the mobile terminal and has received the image data from the imaging device. Therefore, the memories of passing the images in the mutual exchange also remain in the user's memory, and the user's attachment to the images is further increased.

  In the second embodiment, the user may select any mobile terminal 7 among the mobile terminals 7 once recognized by the imaging device 5 so that the user can be excluded from the communication target. FIG. 24 is a diagram showing an example of screen transition in the display unit 42 in this case. As shown in FIG. 24A, when the user touches the mobile terminal 7c that the user wants to exclude from the communication target, the frame part F2 of the touched mobile terminal 7c is deleted, and the recognition state is released (FIG. 24B). ). At this time, the control unit 2C also performs a process of excluding the mobile terminal 7c from the communication target.

  In the second embodiment, guidance information for guiding the moving direction to the communicable area may be superimposed on the area display on the display unit 42 of the mobile terminal 7. FIG. 25 is a diagram illustrating a screen transition example when the display unit 42 of the mobile terminal 7 displays guidance information. In FIG. 25A and FIG. 25B, the entire area of the display unit 42 is not included in the communicable area. For this reason, the control unit 49 calculates a direction in which the entire area is included in the communicable area based on the identification information Id1 to Id4, and displays the guidance information Ar indicating this direction superimposed on the area display. Thereafter, when the entire area of the display unit 42 is included in the communicable area, as shown in FIG. 25C, the display screen becomes bright and the display of the guidance information Ar also disappears. In this case, the user can more easily understand how to move to the communicable area.
