  Next, data handled by the digital camera 1 will be described with reference to FIGS. 4 and 5. FIG. 4 shows the face registration data 50. FIG. 5 shows the schedule table 60.

  The flash memory 25 stores a subject (human) face registration data 50 and a shooting schedule table 60. As shown in FIG. 4, the face registration data 50 includes a subject 51 and recognition data 52. The subject 51 is identification information of a registered person who can be a subject, and is the ID or name of the registered person.

  The recognition data 52 is image data for performing face recognition of each subject (each registered person) of the subject 51. Further, the recognition data 52 is not limited to one image data for each subject, and may be configured as a plurality of image data with different facial expressions, shooting angles, etc. for each subject. The recognition data 52 is not limited to image data, and may be data indicating the facial features of the subject as other face recognition data.

  As shown in FIG. 5, the schedule table 60 includes a time zone 61, position information 62, a shooting scene 63, a subject 64, and a shooting count 65 as items, and each item includes data. Further, all schedules are made up of at least one shooting schedule. All schedules correspond to events such as trips, sports events and excursions. Each shooting schedule is obtained by subdividing the entire schedule (event). For example, when the event is a trip, it becomes the name of each tourist destination of the tourist destination.

  A time zone 61 indicates a time zone of each shooting schedule. The position information 62 indicates the range of longitude and latitude of the shooting location of each shooting schedule. In addition, a1, a2 to h1, h2 of the position information 62 in FIG.

  The shooting scene 63 indicates a shooting scene name, such as a background name and a shooting schedule name. The subject 64 is identification information of each subject (each registered person) and corresponds to the subject 51. The shooting count 65 is the shooting count of each subject in each shooting schedule.

  In the schedule table 60 of FIG. 5, each shooting schedule is a sightseeing spot name of Kinkakuji, Ginkakuji, Nijo Castle, and Kyoto Tower, and each sightseeing spot is set as a shooting scene 63, and the subjects A to C are shot in each shooting scene 63. It is an example of the schedule table which performs.

  Next, the operation of the digital camera 1 will be described with reference to FIGS. First, a setting process executed by the digital camera 1 will be described with reference to FIG. FIG. 6 shows the flow of the setting process.

  The setting process is a process of registering a face of a person who can be a subject and setting a schedule. In the digital camera 1, for example, the setting program read out from the flash memory 25 and appropriately expanded in the RAM 23 triggered by the operation input of the execution of the setting process via the input unit 22, and the cooperation of the CPU 21. The setting process is executed automatically.

  As shown in FIG. 6, first, face registration is executed (step S1). In step S1, first, image data of the face of the subject is acquired by photographing the subject to be registered via the imaging unit 24 and the like, and identification information of the photographed subject is input via the input unit 22 and registered with the image data. The face registration data 50 is stored in the flash memory 25 with the identification information of the person being the recognition data 52 and the subject 51. As a method for acquiring the face image data of the subject to be registered, the image data of the face of the photographed subject recorded in the memory card M is read out and acquired via the recording unit 28, or The image data of the face of the subject may be received and acquired from the external device via the communication unit 26. If the face registration data 50 of the person to be registered is not stored in the flash memory 25, the face registration in step S1 may be executed. In step S 1, the number of shooting times of each subject corresponding to the current shooting scene (number of shooting times = 0 at the start of all schedules) is stored in the RAM 23.

  Then, a schedule setting screen is displayed on the display unit 13, schedule setting is executed (step S2), and the setting process ends. In step S2, according to the schedule setting screen, an operation input of each item (time zone, position information, shooting scene, subject, number of times of shooting) of the shooting schedule is accepted via the input unit 22, and each input item is displayed. The schedule table 60 including the schedule table 60 is generated and stored in the flash memory 25, or the schedule table 60 stored in the flash memory 25 is updated. In the schedule table 60, unnecessary or unknown items may be omitted.

  Next, the photographing process will be described with reference to FIGS. FIG. 7 shows the flow of the photographing process. FIG. 8 shows a flow of the photographing process continued from FIG. FIG. 9 shows an example of changing the schedule table when a virtual scene is inserted. FIG. 10 shows a screen 70a in which the subject A is recognized. FIG. 11 shows a screen 70b in which the subjects A, B, and C are recognized. FIG. 12 shows a schedule table 60c having the same position information.

  The imaging process is a process that is executed after the setting process is executed, detects a deviation in the number of times the subject is captured, notifies the photographer, and performs imaging. In the digital camera 1, for example, when the start of shooting processing is input through the input unit 22 as a trigger, the shooting program read out from the flash memory 25 and appropriately expanded in the RAM 23 and the cooperation of the CPU 21. The shooting process is executed by the operation.

  As shown in FIGS. 7 and 8, first, initial operations such as activation of the GPS unit 27 (current position, current time measurement start) and the like are executed (step S11). After step S11, the GPS unit 27 acquires the current position information and current time information of the digital camera 1 in a predetermined cycle according to the interrupt information output from the RTC 29. In step S1, each shooting schedule in the schedule table 60 is acquired. When the shooting scenes are dense (when the time zone 61 of each shooting schedule is short, etc.), the acquisition period of the current position information and current time information in the GPS unit 27 is assumed to be initially set to be small. According to this, it is possible to detect the switching of the shooting scene with high accuracy.

  The acquisition of the current position information and the current time information from the GPS unit 27 may be configured to appropriately change the acquisition period of the current position information and the current time information in the GPS unit 27 according to the progress of the shooting schedule. . Hereinafter, the current position information and the current time information are the latest acquired from the GPS unit 27.

  Then, the schedule table 60 stored in the flash memory 25 is referred to, and in the time zone 61 corresponding to the current time information acquired in step S11, the number of shootings 65 of each subject in the current shooting scene 63 and the current time information. And the remaining time of the current shooting scene 63 calculated from the time zone 61 is displayed on the display unit 13 (step S12).

  Then, the schedule table 60 is referred to, and it is determined whether or not the current position information acquired by the GPS unit 27 deviates from the shooting scene depending on whether or not the current position information deviates from the position information corresponding to the current shooting scene 63. (Step S13). When the shooting scene has not been departed (step S13; NO), the schedule table 60 is referred to, and the shooting schedule proceeds depending on whether or not the current time information acquired from the GPS unit 27 has shifted to the next time zone 61. It is determined whether or not it has been performed (step S14).

  When the shooting schedule is shifted to the next time zone (step S14; YES), the current shooting scene (shooting schedule) is changed to the next shooting scene, and the record to be read and written to the schedule table 60 is the next record. (Step S15). Since the event does not always proceed according to the schedule, in the case of step S14; YES, the current shooting scene or the like is displayed on the display unit 13 to allow the photographer to check. The schedule table 60 may be reset based on an operation input via the input unit 22. In the schedule table 60, the number of times of shooting of each subject corresponding to the current shooting scene stored in the RAM 23 is reset to 0 corresponding to the shooting scene changed in step S15 (step S16).

  Then, it is determined whether or not the shutter key 7 of the input unit 22 is half-pressed (step S17). When the shutter key 7 is not half-pressed (step S17; NO), the process proceeds to step S17. If the shooting schedule has not been shifted to the next time zone (step S14; NO), the procedure proceeds to step S17.

  If the shooting scene has been deviated (step S13; YES), based on the current position information and current time information acquired from the GPS 27, whether or not the digital camera 1 is at a predetermined time or longer at the current position (predetermined latitude / longitude range). Is determined (step S18). When the current position is longer than the predetermined time (step S18; YES), the current position (predetermined latitude and longitude range) is determined as the virtual scene (step S19). Then, the current shooting scene is changed to a virtual scene, and accordingly, the schedule table 60 is changed, the number of shooting times of each subject stored in the RAM 23 is reset (step S20), and the process proceeds to step S17.

  Here, with reference to FIG. 9, an example of the change of the schedule table 60 in step S20 is shown. As shown in FIG. 9, the schedule table 60a as an example of the schedule table 60 includes a record R1 of a shooting scene 63 (Ginkakuji) whose time zone 61 is 11:00:00 to 12:00. In the schedule table 60a, a shooting scene deviation (step S15; YES) occurs, and it is assumed that the user has been in that position for a predetermined time in step S18.

  Then, in step S20, the record R1 of the schedule table 60a is divided into records R11 and R12 and changed to the schedule table 60b. The end time of the time zone 61 of the record R1 in the schedule table 60a is set to the record R11 at the time 11:15 when the position is moved, and the end time of the time zone 61 of the record R1 is set to the time zone 61. A record R12 in which the current position (longitude x1 to x2, latitude y1 to y2) is set in the position information 62 is added.

  At step S20, the shooting scene 63 is empty in the record R12. The operation input of the shooting scene name is received via the input unit 22 at the time of determining the virtual scene or after that, for example, and set in the shooting scene 63 of the record R12.

  Returning to FIG. 7, when the current position is not longer than the predetermined time (step S18; NO), the increment of the number of photographing stored in the RAM 23 is prohibited (step S21), and the process proceeds to step S17.

When the shutter key 7 is half-pressed (step S17; YES), the lower limit value of the number of times of photographing stored in the RAM 23 is calculated, and whether or not there is a subject whose current number of times of photographing stored in the RAM 23 is below the lower limit value. A determination is made (step S22). The lower limit value is calculated by the following equation (1).
Lower limit value = max (0, average value × weighting coefficient−1) (1)

  In Equation (1), the average value is a value obtained by dividing the total value of the number of shootings 65 of the current shooting scene 63 by the total number of subjects. In Equation (1), the weighting factor is a predetermined fixed value, but may be a value corresponding to the total number of shooting times of the current shooting scene. According to Expression (1), while the average value of the number of times of photographing is small, a subject with a small number of times of photographing is not recognized.

  When there is a subject whose current number of photographing is below the lower limit (step S22; YES), it is determined whether or not the remaining time of the current photographing scene is equal to or less than a predetermined value (step S23). If the remaining time of the current shooting scene is equal to or less than the predetermined value (step S23; YES), the face registration data 50 stored in the flash memory 25 is used to determine in step S22 within the angle of view that is the shooting range. A subject whose current number of photographing is below the lower limit is recognized, and the lens optical system 31, the diaphragm mechanism 32, and the image sensor 33 are driven via the optical system drive unit 34 and drive circuit 36, and the recognized subject is detected. Only the AF and AE are executed and locked (step S24).

  Here, with reference to FIG. 10, the state of recognition of the subject in step S24 is shown. As shown in FIG. 10, it is assumed that the screen 70a is displayed on the display unit 13 in step S24. The screen 70 a includes the number of times 71 of shooting for each subject in the current shooting scene and the remaining time 72. The subject recognized in step S24 is indicated by a mark 73. In step S24, for example, the face image data is cut out from the through image data, the recognition data 52 in which the subject 51 of the face registration data 50 is the subject A is read, and the face image data and the recognition data are compared. If they match, the face image data that is the subject A is recognized. When the recognition data is data indicating facial features, data indicating facial features is extracted from the face image data, and the facial feature data in the facial image data is compared with the recognition data.

  In the screen 70a, since the number of times of shooting of the subject A with the number of shootings 71 is less than the lower limit value and the remaining time 72 is equal to or less than a predetermined value, AF and AE are executed only for the subject A.

  When there is no subject whose current number of photographing is below the lower limit (step S22; NO), or when the remaining time of the current photographing scene is not less than a predetermined value (step S23; NO), the face registration stored in the flash memory 25 is stored. Using the data 50, all the subjects within the angle of view of the through image data are recognized, and the lens optical system 31, the aperture mechanism 32, and the image sensor 33 are driven via the optical system drive unit 34 and the drive circuit 36, AF and AE are executed on the recognized subject and locked (step S25).

  Here, with reference to FIG. 11, how the subject is recognized in step S24 is shown. As shown in FIG. 11, it is assumed that the screen 70b is displayed on the display unit 13 in step S25. The screen 70b includes the number of times 71 of shooting of each subject in the current shooting scene and the remaining time 72. In step S25, for example, each face image data is cut out from the through image data, and the recognition data 52 in which the subject 51 of the face registration data 50 is the subjects A, B, and C is read and recognized as the face image data. And the face image data of the matching subjects A, B, and C are recognized.

  The subject recognized in step S25 is indicated by a mark 73. On the screen 70b, all subjects A, B, and C are recognized, and AF and AE are performed on the subjects A, B, and C.

  Then, after step S24 or S25 is executed, it is determined whether or not the shutter key 7 of the input unit 22 has been fully pressed (step S26). When the shutter key 7 is not fully pressed (step S26; NO), the process proceeds to step S26. When the shutter key 7 is fully pressed (step S26; YES), in the state of step S24 or S25, the subject is photographed by the imaging unit 24 to acquire the image data, and the acquired image data is stored in the recording unit 28. Is recorded in the memory card M via the (step S27).

  Then, out of the number of times of shooting of each subject in the current shooting scene stored in the RAM 23, the number of times of shooting of each subject recognized in steps S24 and S25 is incremented by +1 (step S28). Then, in accordance with the number of shootings incremented in step S28, the number of shootings 65 corresponding to the current shooting scene 63 in the schedule table 60 is updated (step S29).

  Then, the lower limit value of the number of times of photographing stored in the RAM 23 is calculated, and it is determined whether or not there is a subject whose current number of times of photographing stored in the RAM 23 is lower than the lower limit value (step S30). The lower limit is assumed to be calculated by equation (1). When there is a subject whose current number of times of photographing is below the lower limit (step S30; YES), a warning that the number of times of photographing of the subject is small and there is a bias in photographing of the subject is displayed on the display unit 13 with warning information and sound. This is notified by the output of the warning sound by the output unit 29a (step S31). For example, a subject 64 in which the number of shootings of the current shooting scene is lower than the lower limit value is displayed as a thumbnail and output as sound.

  Then, the time zone 61 of the schedule table 60 and the current time information acquired from the GPS unit 27 are referred to, and it is determined whether or not all schedules have been completed (step S32). If the entire schedule has not been completed (step S32; NO), the process proceeds to step S13. When all the schedules have been completed (step S32; YES), the photographing process ends.

  In the above description, an example in which the position information 62 of each shooting scene is different as the schedule table 60 shown in FIGS. 5 and 9 has been described. However, the present invention is not limited to this. For example, as the schedule table 60, as in the schedule table 60c shown in FIG. 12, a subject in each shooting scene 63 (100M run, etc.) is shot with the same position information 62 as when shooting a sports day in a schoolyard of a certain school. It is good also as composition to do.

  According to the present embodiment, the number of times of photographing for each subject is incremented and the number of times of photographing 65 is updated, so that the number of times of photographing of each subject can be grasped for each photographing scene in a plurality of photographing scenes (shooting schedules). . Further, it is determined whether or not there is a subject whose number of photographing 65 is below the lower limit value, and only the subject is recognized, or a digital zoom process described later is performed, and a subject with a small number of photographing 65 is preferentially designated as a subject to be photographed. To do. For this reason, it is possible to eliminate bias in the number of times the subject is shot for each shooting scene in a plurality of shooting scenes, and it is possible to perform equal shooting of the subject for each shooting scene in a plurality of shooting scenes.

  That is, when the shutter key 7 is half-pressed, it is determined whether or not there is a subject whose number of photographing on the RAM 23 is below the lower limit value. Recognize only subjects below the value. Then, since AF and AE are executed and locked only on the recognized subject, only the recognized subject is focused. On the other hand, an unrecognized subject is out of focus, that is, is blurred. Then, even if there are both a subject whose number of photographing 65 is below the lower limit and a subject that is not below the lower limit in the angle of view, only a subject whose number of photographing 65 is below the lower limit is substantially photographed. . As a result, the photographer can substantially shoot only the subject without performing a troublesome operation such as shaking the digital camera 1 so that only the subject whose number of times of photographing 65 is less than the lower limit value is within the angle of view. Can be easily eliminated.

  If there is a subject whose number of shootings on the RAM 23 is below the lower limit by half-pressing the shutter key 7, it is determined whether or not the remaining time of the shooting schedule is less than or equal to a predetermined value, and the remaining time is less than or equal to the predetermined value. In such a case, only a subject whose number of shootings 65 is below the lower limit is recognized. Even in this case, the photographer can substantially photograph only the subject without performing a troublesome operation such as shaking the digital camera 1 so that only the subject whose number of photographing 65 is less than the lower limit value is included in the angle of view. It is possible to easily eliminate bias in the number of times the subject is shot. Furthermore, only when the remaining time is equal to or less than the predetermined value, only a subject whose number of shootings 65 is less than the lower limit is recognized. Therefore, when the remaining time is large, only the subject is within the angle of view by the user's operation. The convenience can be improved.

  When the digital camera 1 deviates from the current shooting scene 63 and a predetermined time or more has elapsed, a virtual scene is determined as a shooting scene and added to the schedule table 60 and changed. For this reason, even when the schedule is changed and a new shooting scene is shot, the shooting scene can be added to the shooting schedule as a virtual scene and the subject can be shot evenly.

  In addition, when there is a subject whose number of photographings 65 is below the lower limit, the display unit 13 and the sound output unit 29a notify the photographer that the subject is fewly photographed and there is a bias in photographing the subject. By this notification, the photographer can adjust the angle of view to eliminate the deviation in the number of times of photographing of a plurality of subjects, and can perform uniform photographing of the subjects.

  The description in the above embodiment is an example of a photographing apparatus, a photographing method, and a program according to the present invention, and the present invention is not limited to this.

  For example, in the above-described embodiment, the configuration is configured to prevent deviation in the number of times the subject is captured in still image capturing. However, the present invention is not limited to this. In moving image shooting, it is possible to eliminate the bias of the shooting amount of the subject. FIG. 13 shows the appearance of the movie camera 1a.

  The movie camera 1a as shown in FIG. 13 may be configured to have a function of shooting a subject without deviation in shooting time for each shooting scene. More specifically, in the movie camera 1a, the subject is recognized at the time of moving image shooting, and the shooting time as the shooting amount is counted for each recognized subject, and when the shooting time of a certain subject falls below the lower limit value, A configuration may be adopted in which a warning indicating that there is a bias in shooting of the subject is short and the warning is displayed and voiced to notify the photographer.

  In the above embodiment, AF and AE are performed on the recognized subject. However, the present invention is not limited to this. When the shutter key 7 is half-pressed, it is determined whether or not there is a subject whose number of shots on the RAM 23 is below the lower limit. If there is a subject whose number of shots 65 is below the lower limit, the subject is the center of the angle of view. It is good also as a structure which performs a digital zoom automatically so that it may be located in FIG. In this case, a control signal is output from the CPU 21 to the signal processing circuit 40 so as to control the subject whose number of shootings 65 is below the lower limit value to be positioned at the center of the angle of view. Then, the signal processing circuit 40 extracts the digital zoom area image data from the frame data (cuts out image data of a predetermined amount of zoom magnification centered on the subject whose number of shootings 65 is below the lower limit value from the frame data. Then, image data for one screen is generated). Also, the image data that has been subjected to the digital zoom process is enlarged and displayed on the display unit 13 full. Note that the image data in the digital zoom area may include a part of the subject whose number of shootings 65 is equal to or greater than the lower limit. According to this, the photographer can photograph only the subject without performing a troublesome operation such as shaking the digital camera 1 so that only the subject whose number of photographing 65 is less than the lower limit value is within the angle of view. It is possible to easily eliminate the deviation of the number of times of photographing.

  Further, when there is an object whose number of shootings 65 on the RAM 23 is below the lower limit by half-pressing the shutter key 7, it is determined whether or not the remaining time of the shooting schedule is equal to or less than a predetermined value. In some cases, the digital zoom may be automatically performed so that the subject is positioned at the center of the angle of view. Also by this, the photographer can shoot only the subject without performing a troublesome operation such as shaking the digital camera 1 so that only the subject whose number of times of photographing 65 is less than the lower limit value is within the angle of view. The bias in the number of times can be easily eliminated. Further, only when the remaining time is less than or equal to a predetermined value, only the subject whose number of shots 65 is below the lower limit is recognized and zoomed. Therefore, when the remaining time is large, only the subject is imaged by the operation of the photographer. It can be adjusted to fit within the corner, improving convenience.

  Of course, the detailed configuration and detailed operation of each component of the digital camera 1 in the above embodiment can be changed as appropriate without departing from the spirit of the present invention.
