  Hereinafter, a digital camera according to a first embodiment will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a digital camera according to the embodiment. The digital camera 2 is provided with a CPU 4 that controls each part of the digital camera 2 in an integrated manner. The CPU 4 displays an operation unit 6, a GPS 5 for positioning the current position based on signals received from GPS satellites, a communication unit 8 for transmitting image data of an image to be uploaded to a web server via the Internet, a through image, etc. A display control unit 12 that performs display control of the LCD display unit 10, a touch panel 14 that detects the position of a touch with a finger or the like in the LCD display unit 10, an imaging device 16 that captures an object light and generates an imaging signal, and the imaging device 16 An image storage unit 18 for temporarily storing image data of a captured image; a personal information storage unit 20 for storing a graphic pattern drawn by dots or lines as personal authentication data; and a memory card 21 for storing image data. A memory card slot 23 to be mounted is connected.

  Here, the operation unit 6 includes a power switch (not shown), a shutter button (not shown), and the like. Further, in the graphic pattern, there are a first graphic pattern used when determining whether or not to set the post mode to be described later, and a second graphic pattern used when determining whether or not the post mode is ended. The figure pattern is registered in the personal information storage unit 20 in advance by the operator drawing a predetermined figure on the LCD display unit 10 with a finger.

  Next, processing of the digital camera 2 according to the first embodiment will be described with reference to the flowchart shown in FIG. First, when the power is turned on by the operation of the operator, the CPU 4 starts photographing of a through image by the imaging device 16 and displays the photographed through image on the LCD display unit 10 (step S1).

  Next, the CPU 4 determines whether a touch panel input has been made (step S2). That is, it is determined by the touch panel 14 whether or not the finger of the operator has touched the LCD display unit 10. If the touch panel is not input (step S2: No), the CPU 4 ends the series of processes if a predetermined time has elapsed since the power was turned on (step S3: Yes). On the other hand, if the predetermined time has not elapsed since the power was turned on (step S3: No), the process of step S2 is repeated.

  When touch panel input is performed (step S2: Yes), the CPU 4 determines whether the touch panel input has been pressed for a long time (step S4). In addition, determination of whether it is pressing for a long time is performed using a well-known technique. If the touch panel input is not pressed for a long time (step S4: No), that is, if the touch panel input is pressed for a short time, the CPU 4 detects the position on the touch panel 14 touched by the operator's finger and detects the detected position. After performing the touch AF to focus on (step S5), the image pickup device 16 captures an image (step S6).

  On the other hand, when the touch panel input has been pressed for a long time (step S4: Yes), the CPU 4 matches the locus of the finger touching the LCD display unit 10 with the first figure pattern stored in the personal information storage unit 20. The personal authentication is performed by determining whether or not it is (step S7). Here, matching includes not only perfect matching but also near matching. If the locus of the finger does not match the first figure pattern (step S7: No), an error message such as "pattern does not match. Please draw another figure." Is displayed on the LCD display unit 10 (step S8) , And return to the process of step S2.

  When the locus of the finger matches the first figure pattern (step S7: Yes), the CPU 4 sets a posting mode for uploading the photographed image to a predetermined image posting site (not shown) provided by the web server. (Step S9). Here, when the shutter button is operated and the image of the subject is photographed (step S10), the CPU 4 temporarily stores the image data of the photographed image in the image storage unit 18. Next, the CPU 4 causes the communication unit 8 to transmit the image data read from the image storage unit 18 to the web server via the Internet, and uploads an image based on the image data to the image posting site (step S11).

  Next, the CPU 4 determines again whether a touch panel input has been made (step S12). When touch panel input is not performed (step S12: No), the process of steps S10 to 12 is repeated.

  On the other hand, when the touch panel input is performed (step S12: Yes), the CPU 4 determines whether the touch panel input has been pressed for a long time (step S14). If the touch panel input is not pressed for a long time but for a short time (step S14: No), an error message such as “pattern does not match. Please draw another figure.” Is displayed on the LCD display unit 10 ( Step S16) Return to the process of step S12.

  On the other hand, when the touch panel input has been pressed for a long time (step S14: Yes), the CPU 4 matches the second figure pattern stored in the personal information storage unit 20 with the locus of the finger touching the LCD display unit 10. It is determined whether or not (step S15). If the locus of the finger does not match the second figure pattern (step S15: No), the process proceeds to step S16, and an error message such as "pattern does not match. Please draw a figure again." Is displayed on.

  On the other hand, when the locus of the finger matches the second figure pattern (step S15: Yes), the CPU 4 ends the posting mode (step S17), and determines whether an operation to end the photographing is performed (step S18). ). When the operation to end the shooting is not performed (step S18: No), the process returns to the process of step S2. On the other hand, when the operation to end the shooting is performed (step S18: Yes), a series of processing ends.

  According to the digital camera 2 of the first embodiment, since personal authentication is performed based on the locus of the finger recognized by the touch panel 14, an authentication screen such as a password input is obtained even if personal authentication is performed during the photographing operation. Need not be displayed on the LCD display unit 10, and personal authentication can be performed without disturbing the photographing operation of the operator. That is, the operator can perform the personal authentication operation while viewing the through image, and upload the captured image to the image posting site.

  In addition, even if the operator wants to shoot and upload the shooting while shooting through images, it is possible to quickly complete the personal authentication operation and shift to the posting mode simply by tracing the display screen with a finger.

  In addition, it is possible to perform personal authentication with a high security level by determining whether or not the trajectory of the finger of the operator who has touched the LCD display unit 10 matches the graphic pattern drawn by the operator in advance.

  Further, in the case of determining whether or not the post mode ends, the following effects can be obtained by performing personal authentication using a graphic pattern different from that in the case of determining whether or not the post mode is set. For example, it is assumed that the digital camera 2 is stolen by a theft person who knows the first graphic pattern. Then, it is assumed that the theft person touch-inputs the locus of the first figure pattern to set the posting mode, and uploads the photographed image to the image posting site. Here, it is assumed that positional information acquired by the GPS 5 and date and time information are added to the image data of the image to be posted. In such a case, if the theft can not end the posting mode by touching the locus of the second graphic pattern and ending the posting mode, the image is continuously uploaded to the image posting site each time shooting is performed. From the position information added to the image data of the image, it is possible to track the current position of the robber.

  Next, processing of the digital camera according to the second embodiment will be described. In the first embodiment, the digital camera according to the second embodiment uploads a moving image being shot to a predetermined image posting site when personal authentication is performed during moving image shooting. It is a thing. In addition, as personal authentication data, the third graphic pattern used when determining the availability of setting of the video posting mode to be described later, and the fourth graphic pattern used when determining the availability of termination of the video posting mode It is stored in the storage unit 20. Therefore, in the second embodiment, portions different from the first embodiment will be described in detail, and the description of the overlapping portions will be omitted as appropriate.

  First, a moving image shooting mode for shooting a moving image is set by the operation of the operator, and when the shutter button is operated, the CPU 4 starts shooting a moving image by the imaging device 16 (step S31). Are sequentially stored in the image storage unit 18. Then, the image data is sequentially read out from the image storage unit 18, and an image based on the image data is displayed on the LCD display unit 10. The image data of the image displayed on the LCD display unit 10 is stored in the memory card 21.

  Here, when touch panel input is performed (step S32: Yes), the CPU 4 determines whether the touch panel input has been pressed for a long time (step S34). When the touch panel input is not pressed for a long time but for a short time (step S34: No), the CPU 4 detects the position on the touch panel 14 touched by the finger of the operator and focuses on the detected position (step S36). Such a short press during moving image shooting is performed when it is desired to change the focal position of the subject.

  On the other hand, when the touch panel input has been pressed for a long time (step S34: Yes), the CPU 4 matches the third figure pattern stored in the personal information storage unit 20 with the locus of the finger touching the LCD display unit 10. The personal authentication is performed by determining whether or not it is (step S37). When the locus of the finger does not match the third figure pattern (step S37: No), an error message such as "pattern does not match. Please draw another figure." Is displayed on the LCD display unit 10 (step S38) , And return to the process of step S32.

  When the locus of the finger matches the third figure pattern (step S37: Yes), the CPU 4 sets a moving picture posting mode for uploading the moving picture being photographed to a predetermined picture posting site halfway (step S39). Next, the CPU 4 transmits the image data sequentially read from the image storage unit 18 from the communication unit 8 to the web server via the Internet (step S41). As a result, during moving image shooting, a moving image shot after personal authentication is uploaded to the image posting site.

  Next, the CPU 4 determines again whether a touch panel input has been made (step S42). When the touch panel input is not performed (step S42: No), the process returns to the process of step S42, and the uploading of the moving image being captured is continued.

  On the other hand, when the touch panel input is performed (step S42: Yes), if the touch panel input is pressed for a long time (step S44: Yes), the CPU 4 selects the locus of the finger touching the LCD display unit 10 as the personal information storage unit 20. It is determined whether or not it matches the fourth graphic pattern stored in (step S45). When the locus of the finger does not match the fourth figure pattern (step S45: No), the CPU 4 displays an error message such as "pattern does not match. Please draw a figure again." Step S46) Return to the process of step S42.

  If the trajectory of the finger matches the fourth figure pattern (step S45: Yes), the CPU 4 ends the moving picture posting mode (step S47), and determines whether an operation to end moving picture shooting has been performed (step S48). . If the operation to end moving image shooting is not performed (Step S48: No), the process returns to Step S32, and if the operation to end moving image shooting is performed (Step S48: Yes), a series of processing ends.

  According to the digital camera according to the second embodiment, the operator performs the personal authentication operation while viewing the moving image displayed on the LCD display unit 10, and the moving image being captured is transferred from the middle to the image posting site. It can be uploaded. In addition, uploading of a moving image can be terminated halfway by performing the personal authentication operation again during shooting.

  The image captured in the posting mode of the first embodiment described above may be a moving image as well as a still image. In this case, when the moving image is captured in the posting mode, the CPU 4 sequentially reads out the image data of the moving image stored in the image storage unit 18 and transmits the image data to the web server via the Internet. Then, when the moving image shooting is finished and the image data can not be transmitted to the web server, the uploading of one moving image to the image posting site is completed.

  In the first embodiment described above, when the touch panel input is a short press, it is not necessary to perform the touch AF. For example, as shown in FIG. 4, it is assumed that a "MENU" button for displaying a menu screen is displayed on the LCD display unit 10 during shooting of a through image. Here, when the “MENU” button is touched, the screen of the through image displayed on the LCD display unit 10 may be switched to the menu screen.

  Further, in the above-described first embodiment, the photographing processing at the time of touch AF may be performed immediately after focusing on the position on the touch panel 14 touched by the finger, or focuses on the touched position. After that, it may be performed when the shutter button is operated.

  Further, in the above-described first embodiment, when the posting mode is ended, the touch panel input may not necessarily be used. For example, when the posting mode continues, as shown in FIG. 4, an icon such as “in login” is displayed. Then, the posting mode may be ended when the icon is touched.

  In each of the above-described embodiments, it is not necessary to touch and input different graphic patterns at the time of setting and at the time of ending of the posting mode and the moving picture posting mode. That is, when the first graphic pattern and the third graphic pattern are touch-input, the posting mode and the moving picture posting mode may be ended.

  In each of the above-described embodiments, the touch input does not have to be performed with a finger, and may be performed by an operation member such as a pointing rod.

  In each of the above-described embodiments, the digital camera 2 may be either a compact camera or a single-lens reflex camera.

  Next, a digital camera according to a third embodiment will be described with reference to the drawings.

  BACKGROUND Conventionally, there has been known a hand-shaped authentication reference point detection device that performs personal authentication by recognizing the shape of a palm (see, for example, JP-A-2004-348522).

  By the way, in this palm shape authentication reference point detection device, since a simple model in which the shape of the finger is replaced with a straight line is used as data for personal authentication, for example, a person with a similar palm shape is the palm shape authentication reference. When a point detection device is used, there is a possibility that personal identification may be made erroneously.

  In addition, when performing personal authentication by the above-described method with a digital camera, it is necessary to mount the hand-shaped authentication reference point detection device on the digital camera, which causes a problem of an increase in manufacturing cost.

  An object of the invention according to the third embodiment is to provide an inexpensive imaging apparatus capable of highly accurate personal identification.

  FIG. 6 is a perspective view of the digital camera 22 according to the third embodiment as viewed from the back. The digital camera 22 includes a housing 24 made of metal or plastic, and the LCD display unit 26, a multi-selector 28, and a zoom button 29 are provided on the back of the housing 24.

  Further, a power button 32 and a shutter button 34 are provided on the top surface of the housing 24, and a lens barrel 36 for accommodating a photographing lens (see FIG. 7) is provided on the front surface of the housing 24.

  FIG. 7 is a block diagram showing the configuration of a digital camera 22 according to the third embodiment. The digital camera 22 includes a CPU 44 that controls each part of the digital camera 22 in an integrated manner. In the CPU 44, an operation unit 46, a display control unit 48 that performs display control of the LCD display unit 26, a touch panel 50 that performs an input operation by touching an icon displayed on the LCD display unit 26 with a finger, Imaging unit 54, an image storage unit 56 for temporarily storing image data of an image captured by the imaging unit 54, an image processing unit 58 for performing pixel binarization processing on the image data, and personal authentication. An information storage unit 59 for storing personal identification data to be used and a memory card slot 62 for mounting a memory card 60 for storing image data are connected.

  Here, the operation unit 46 includes the multi-selector 28, the zoom button 29, the power button 32, the shutter button 34, and the like. The imaging unit 54 further includes a lens driving unit 66 that controls driving of the imaging lens 64, an imaging device 68 configured of a CCD or the like, a lens driving unit 62, and a photography control unit 70 that controls driving of the imaging device 68. ing.

  Next, with reference to a flowchart shown in FIG. 8, a registration process of registering personal identification data in advance in the digital camera 22 according to the third embodiment will be described. In addition, below, the case where the operator A makes the bracelet part of a wristwatch a registration target object is demonstrated as a specific example.

  First, when the power is turned on, the CPU 44 causes the photographing unit 54 to start photographing the through image, and displays the photographed through image on the LCD display unit 26.

  Next, when the operator A operates, for example, the touch panel 50 to set a registration mode for registering personal authentication data (step S101), the CPU 44 drives the lens drive unit 66 by the imaging control unit 70, and the imaging unit The photographing lens 64 is moved so that the photographing angle of view of 54 becomes the angle of view (W1) (step S102). Here, the angle of view (W1) is the shooting angle of view on the widest side in the shooting unit 54.

  Next, the CPU 44 displays a message such as “Please let the object to be registered appear on the screen and press the shutter button” on the LCD display unit 26 or the like. Here, as shown in FIG. 9, when the operator A extends his arm and brings the portion of the bracelet 82 of the watch 80 attached to the wrist close to the front of the lens barrel 36, the portion of the bracelet 82 of the watch 80 The through image is displayed on the LCD display unit 26.

  Next, the operator A adjusts the position of the digital camera 22 so that the bracelet 82 is displayed near the center of the display screen of the LCD display 26, for example, and operates the shutter button 34.

  When the shutter button 34 is operated, the CPU 44 performs continuous shooting while sequentially changing the shooting angle of view of the shooting unit 54 to the tele side (step S103). For example, as shown in FIG. 10, the CPU 44 first captures an image a in a state in which the shooting angle of view of the shooting unit 54 matches the angle of view (W1). Next, the image b is shot in accordance with the shooting angle of view of the shooting unit 54 with the angle of view (W2) on the tele side of the angle of view (W1). Then, the image c is photographed at the angle of view (W3) on the tele side of the angle of view (W2).

  Thereafter, in the same manner, the CPU 44 captures the image d at the angle of view (M1), captures the image e at the angle of view (M2), and captures the image f at the angle of view (M3). Furthermore, the image g is taken at the angle of view (T1), the image h is taken at the angle of view (T2), and the image i is taken at the angle of view (T3). Image data of a plurality of continuously captured images is stored in the image storage unit 56.

  Next, the CPU 44 reads a plurality of continuously captured image data from the image storage unit 56, and the image processing unit 58 performs pixel binarization processing on each image data (step S104). For example, the differential value of each pixel constituting the image data is calculated, and if the differential value is equal to or greater than the threshold value, the pixel value of that pixel is determined to be “High”, and if the differential value is less than the threshold value, the pixel The pixel value of is determined to be "Low".

  Next, the CPU 44 controls the image processing unit 58 to generate outline image data of an outline image whose outline is a pixel determined to be “High” from each image data. That is, as shown in FIG. 11, outline image data of the outline image a is generated from the image data of the image a. Further, outline image data of the outline image b is generated from the image data of the image b. Similarly, contour image data of contour image c is generated from image data of image c, contour image data of contour image d is generated from image data of image d, and contour image of contour image e from image data of image e Data is generated, contour image data of contour image f is generated from image data of image f, contour image data of contour image g is generated from image data of image g, contour of contour image h from image data of image h Image data is generated, and contour image data of contour image i is generated from image data of image i.

  Next, the CPU 44 detects the center of gravity of the bracket portion constituting the bracelet 82 from each of the contour image data (step S105). For example, as shown in FIG. 11, the CPU 44 detects the center of gravity 1 (a), the center of gravity 2 (a),..., The center of gravity n (a) from the contour image data of the contour image a. Next, the center of gravity 1 (b), the center of gravity 2 (b),..., The center of gravity n (b) are detected from the outline image data of the outline image b. Similarly, this process is repeated for each contour image data until the centroid point 1 (i), the centroid point 2 (i),..., The centroid point n (i) are detected from the contour image data of the contour image i. .

  Next, the CPU 44 calculates coordinates of the position of the center of gravity in each contour image data, and generates locus data indicating transition of the coordinates of each center of gravity (step S106). Specifically, transition of coordinates of center of gravity 1 (a) → center of gravity 1 (b) → ... → center of gravity 1 (i), center of gravity 2 (a) → center of gravity 2 (b) → ... → center of gravity Transition of coordinates of 2 (i), ..., and center of gravity n (a) → center of gravity n (b) → ... → locus data indicating transition of coordinates of center of gravity n (i) is generated. Next, the CPU 44 stores the locus data in the information storage unit 59 as personal authentication data (step S107).

  Next, with reference to a flowchart shown in FIG. 12, a personal authentication process for performing personal authentication using the digital camera 22 according to the third embodiment will be described. In addition, below, the case where the operator A who registered personal authentication data by making bracelet 82 into a registration target object performs a personal authentication process is demonstrated to an example. In addition, since there are many parts which overlap with registration processing in a personal-identification process, description is suitably abbreviate | omitted about the overlapping parts.

  First, when the power is turned on, the CPU 44 causes the photographing unit 54 to start photographing the through image, and displays the photographed through image on the LCD display unit 26.

  Next, when the operator A operates, for example, the touch panel 50 to set the personal authentication mode to perform personal authentication (step S201), the CPU 44 causes the “object to be authenticated to be displayed on the screen and performs a predetermined operation. And display a message such as “Please.” On the LCD unit 26.

  Here, when the operator A brings the portion of the bracelet 82 close to the front of the lens barrel 36, a through image of the portion of the bracelet 82 of the wristwatch 80 is displayed on the LCD display unit 26. Then, when the operator A operates the zoom button 29, the CPU 44 performs continuous shooting while changing the shooting angle of view of the shooting unit 54 according to the operation of the zoom button 29 (step S202). For example, when the operator A performs an operation to sequentially change the shooting angle of view to the tele side within the range from the angle of view (W3) to the angle of view (M3), the CPU 44 determines the angle of view (see FIG. 13). The image c 'is photographed in W3), the image d' is photographed in the angle of view (M1), the image e 'is photographed in the angle of view (M2), and the image f' is photographed in the angle of view (M3). Image data of a plurality of continuously captured images is stored in the image storage unit 56.

  Next, the CPU 44 reads a plurality of continuously captured image data from the image storage unit 56, and the image processing unit 58 performs pixel binarization processing on each image data (step S203), and generates outline image data. Do.

  For example, as shown in FIG. 14, contour image data of contour image c 'is generated from image data of image c', contour image data of contour image d 'is generated from image data of image d', and image e 'is generated. The outline image data of the outline image e ′ is generated from the image data of the above, and the outline image data of the outline image f ′ is generated from the image data of the image f ′.

  Next, the CPU 44 detects the center of gravity of the fitting portion of the bracelet 82 from each of the contour image data (step S204). For example, as shown in FIG. 14, the center of gravity 1 (c '), the center of gravity 2 (c'),..., The center of gravity n (c ') are detected from the contour image data of the contour image c'. Next, the barycentric point 1 (d '), the barycentric point 2 (d'), ..., and the barycentric point n (d ') are detected from the outline image data of the outline image d. Similarly, from the contour image data of the contour image e, the gravity center point 1 (e '), the gravity center point 2 (e'), ..., the gravity center point n (e ') are detected, and from the contour image data of the contour image f, The barycentric point 1 (f '), the barycentric point 2 (f'), ..., the barycentric point n (f ') are detected.

  Next, the CPU 44 calculates coordinates of the position of the center of gravity in each contour image data, and generates locus data indicating transition of the coordinates of each center of gravity (step S205). Specifically, transition of coordinates of center of gravity 1 (c ') → center of gravity 1 (d') → center of gravity 1 (e ') → center of gravity 1 (f'), center of gravity 2 (c ') → center of gravity Transition of coordinates of point 2 (d ') → center of gravity 2 (e') → center of gravity 2 (f '), ..., and center of gravity n (c') → center of gravity n (d ') → center of gravity n (n e ′) → trajectory information indicating transition of coordinates of center of gravity point n (f ′) is generated.

  Next, the CPU 44 reads the personal identification data from the information storage unit 59, and the locus of the coordinates of the center of gravity based on the locus information (hereinafter referred to as the locus based on locus information) is the locus of the coordinates of the center of gravity based on the personal identification data. It is determined whether or not it substantially coincides with part or all (hereinafter referred to as a locus based on personal identification data) (step S206).

  If the locus based on the locus information substantially matches a part or all of the locus based on the personal identification data (step S206: Yes), the CPU 44 determines that the personal identification is successful, and outputs the image data from the digital camera 22 Allow In the present embodiment, the gravity center point 1 (c ') included in the locus information → gravity center point 1 (d') → gravity center point 1 (e ') → locus of gravity center point 1 (f'), gravity center point 2 (C ') → center of gravity 2 (d') → center of gravity 2 (e ') → locus of center of gravity 2 (f'), ..., and center of gravity n (c ') → center of gravity n (d') → The locus of the center of gravity n (e ') → the center of gravity n (f') is respectively included in the personal authentication data: center of gravity 1 (c ') → center of gravity 1 (d') → center of gravity 1 (e ') → locus of centroid point 1 (f ′), centroid point 2 (c ′) → centroid point 2 (d ′) → centroid point 2 (e ′) → locus of centroid point 2 (f ′), and centroid point n (n c ') → center of gravity n (d') → center of gravity n (e ') → center of gravity n (f') That is, the locus based on the locus information substantially coincides with a part of the locus based on the personal identification data. Therefore, the CPU 44 determines that the personal authentication is successful, and permits the output of the image data from the digital camera 22.

  When output of image data is permitted, for example, it is possible to print a captured image with a printer (not shown) or upload it to a server (not shown).

  On the other hand, when the locus based on the locus information does not substantially coincide with part or all of the locus based on the personal authentication data (step S206: No), the CPU 44 determines that the personal authentication can not be performed. Then, the output of the image data from the digital camera 22 is prohibited, and a message such as “Failed in personal authentication” is displayed on the LCD display unit 26. When output of image data is prohibited, for example, printing of a photographed image by a printer (not shown) or uploading to a server is prohibited.

  When the output of image data is permitted or prohibited, the memory card 60 may be treated as an external device of the digital camera 22. In this case, for example, the image data is stored in the memory card 60 only after the output of the image data is permitted, so that photographing can be substantially enabled. In addition, when the output of image data is prohibited, when the shutter button 34 is operated, even if the image data is stored in the internal memory, it is not stored in the memory card 60, so that shooting is substantially performed. Make it impossible.

  According to the invention of the third embodiment, it is possible to generate complicated personal identification data by using a zoom function generally possessed by a camera and an image processing function. An inexpensive digital camera 22 can be provided. Also, if the operator registers personal authentication data in advance, personal authentication can be easily performed simply by operating the zoom button 29.

  In addition, personal authentication data is generated by continuously shooting the bracelet 82 while changing the shooting angle of view of the shooting unit 54 in one direction in the registration mode, so the shooting angle of view of the shooting unit 54 in the opposite direction in the personal authentication mode Even if the bracelet 82 is photographed by changing V, it is not possible to acquire trajectory information of a trajectory that substantially matches a part or all of the trajectory based on the personal identification data. Therefore, for example, even if a third party who illegally obtained the digital camera 22 and the wristwatch 80 changes the shooting angle of view of the shooting unit 54 in the opposite direction and shoots the bracelet 82, personal authentication is not performed.

  Further, in the personal authentication mode, since the personal authentication can be performed if the locus based on the locus information substantially matches a part of the locus based on the personal authentication data, all zooms taken by the operator A during the registration processing are performed. There is no need to zoom in the range, and the authentication operation can be easily performed.

  Further, in the registration mode and the personal authentication mode, not a complicated image processing but a simple binarization process, the registration process and the personal authentication process can be performed at a rapid processing speed.

  In the third embodiment described above, the lens distortion correction may be set to be on / off by the operation of the touch panel 50 or the like. In this case, when an object is photographed by the photographing unit 54, image data of a distorted object image reflecting the characteristics of the photographing lens 64 is acquired. Therefore, the operator A can generate personal authentication data having a more complicated trajectory utilizing distortion by performing the registration process with the lens distortion correction turned off.

  In addition, when personal authentication succeeds in the third embodiment described above, things other than the permission of the output of the image data may be performed. For example, when the personal authentication is successful, the CPU 44 sets the shooting mode of the digital camera 22 to a shooting condition dedicated to the operator A registered in advance by the operator. On the other hand, when the personal authentication fails, it is prohibited to set the photographing condition dedicated to the operator A.

  In the third embodiment described above, the operator A operates the zoom button 29 to continuously shoot the bracelet 82 while changing the shooting angle of view, similarly to the case of the personal authentication process in the registration process. It is also good. In this case, the operator A can generate personal identification data having a more complicated trajectory.

  For example, the operator A changes the shooting angle of view as follows: angle of view (W3) → angle of view (M1) → angle of view (M2) → angle of view (M3) → angle of view (T1) → angle of view (M3) The folding point (field angle (T1)) is provided to continuously shoot the bracelet 82 continuously. This makes it difficult for a third party who illegally obtains the digital camera 22 and the wristwatch 80 to easily guess in which direction the zoom button 29 should be operated, even when trying to perform personal identification. Therefore, unauthorized use of the digital camera 22 by a third party can be accurately prevented.

  In this case, in the personal identification process, it may be determined that the personal identification has succeeded if the locus based on the locus information substantially matches the portion including the turning point of the locus based on the personal identification data. For example, if the trajectory corresponding to the angle of view (M3) → the angle of view (T1) → the angle of view (M3) can be confirmed based on the trajectory information, output of image data from the digital camera 22 is permitted.

  Further, in the third embodiment described above, the registration process may be performed in a state where a specific imaging condition is set. For example, when setting the registration mode, the operator A sets the ISO sensitivity to a high sensitivity. Then, the bracelet 82 is continuously photographed while changing the photographing angle of view of the photographing unit 54 in a state where the ISO sensitivity is set to a high sensitivity. Here, when the binarization processing is performed on the continuously captured image data, the CPU 44 can not recognize the outlines of all the bracket parts from the image data captured with high sensitivity, as shown in FIG. Then, contour image data is generated in which the contours of the plurality of fitting parts are recognized as one contour.

  Here, the number of gravity center points is smaller than that in the normal case where ISO sensitivity is not set to high sensitivity, and the position of the gravity center point is also recognized at a position different from that in the normal case. For this reason, trajectory data different from that in the normal case is generated.

  In this case, if the operator who wants to shoot with the digital camera 22 does not set the ISO sensitivity to high in the personal authentication mode, he or she may operate the zoom button 29 to continuously shoot the bracelet 82. It is not possible to acquire a locus that substantially matches part or all of the locus based on the personal identification data, and personal identification is not performed. Therefore, unauthorized use of the digital camera 22 when the digital camera 22 is stolen by a third party can be accurately prevented.

  In this case, in addition to the ISO sensitivity, the exposure correction value or the white balance may be set to a predetermined value as a specific photographing condition.

  Further, in the above-described third embodiment, the imaging device does not necessarily have to be the digital camera 22, and may be a smartphone, a mobile phone, a tablet terminal or the like.
