(Description of operation of the embodiment)
Next, an example of the operation of the photographing apparatus shown in FIG. 2 will be described using the flowchart shown in FIG. FIG. 3 is a flowchart showing an example of the flow of the person photographing process performed in the photographing apparatus of FIG. 2, and a predetermined number of images are photographed as the number of operation image acquisitions at the time of one shutter pressing operation. In this case, the best shot image of each of a plurality of persons as subjects is extracted from the acquired images and combined with the background image to output one generated image. Show. In the flowchart shown in FIG. 3, the number of subjects is M (M: the number specified by the user), and the number of acquired images indicating the number of captured images to be acquired at the time of pressing the shutter is n (n: image acquisition). Fi is the i-th acquired image, and BS is the best shot degree that is an index that indicates the quality of the image (and the maximum best shot that indicates the degree to which the image is the best among the processed images). The degree is expressed as BSmax).

  When the process of FIG. 3 is activated (step S301), when the camera operation is instructed by the key operation unit 206 (step S302), the camera sensor 201 and the image processing unit 203 are activated by an instruction of the CPU 204, and the image processing unit 203 is activated. Performs initialization such as initialization of the maximum best shot degree (BSmax = 0) and deletion of image data in the processing memory 207 (step S303).

  After starting the preview of the subject by the camera sensor 201 (step S304), M people are set as the number of subjects by the key input from the key operation unit 206 by the user (step S305). Thereafter, it is confirmed whether or not a shutter pressing operation has been performed (step S306). If the shutter pressing operation has not been performed (NO in step S306), a predetermined allowable time has not passed (step S325). NO), returning to the process of step S306, the confirmation of the shutter pressing operation is repeated.

  When the shutter is pressed by a key input from the key operation unit 206 by the user (YES in step S306), the camera sensor 201 continuously captures n images (n: arbitrary) A positive integer and a predetermined number of captured images) are acquired and stored in the processing memory 207, and the stored n captured images are sequentially transferred from the processing memory 207 one by one. Then, the processing from step S308 to step S319 is repeated. First, the first captured image (F1) is extracted (step S308), and the extracted first captured image (F1) is separated into a person partial image and a background image (step S309), and the background image is extracted. Save in the processing memory 207 (step S310).

  On the other hand, a labeling process for assigning labels (R1, R2,... Rs,..., RM) for identifying each person of the subject is performed on each person partial image extracted from the photographed image (F1) ( Step S311). Next, by repeating the processes from step S312 to step S317, the process of determining the best shot image of each person of the subject is performed.

  That is, for each given label (R1, R2,... Rs,..., RM), that is, for each person of the subject, the best shot degree BS of each person partial image (for example, in the case of label Rs, the best shot degree BSs) is calculated (step S313), and the calculated best shot degree BS of each person partial image (for example, the best shot degree BSs in the case of a person with label Rs) has been stored in the processing memory 207 so far. It is compared with the maximum best shot degree BSmax for the person partial image for each person (for example, in the case of a person with the label Rs, the maximum best shot degree to date for the person partial image of the person corresponding to the label Rs) (step S314).

  As described above, the best shot degree of each person partial image is determined by whether the person part in the person partial image is facing the front, looking at the front with eyes open, And the degree of sharpness as an image, the vividness of colors, the brightness, and the like are parameterized.

  If the calculated best shot degree BS of each person partial image does not exceed the maximum best shot degree BSmax of each person partial image stored in the processing memory 207 so far (NO in step S314), the current save is performed. The maximum best shot degree BSmax of each person partial image that has been set is not updated.

  On the other hand, if the maximum best shot degree BSmax of each person partial image stored in the processing memory 207 is exceeded (YES in step S314), each person part currently stored in the processing memory 207 is displayed. The maximum best shot degree BSmax of the image is updated with the calculated best shot degree BS of each person partial image (step S316), and the person partial image is held in the processing memory 207 as the best shot image up to the present ( For example, in the case of the person with the label Rs, the maximum best shot degree BSmax corresponding to the label Rs in the processing memory 207 is updated as the maximum best shot degree BSmax of the person corresponding to the label Rs so far, and the person corresponds to the label Rs. It is stored as the best shot image of the person up to the present).

  By repeating the determination processing regarding the necessity of updating the maximum best shot degree BSmax from the first label R1 until reaching the final label RM of the number of subjects M (steps S312 to S317), the first image The process of determining the best shot degree BS for a plurality of subjects of the subject in (F1) is terminated, and after the next second image (F2), the person and the label are linked to the same as the first person partial image. The same process is repeated until the number n of image acquisitions is reached (step S307 to step S318). Through such repeated processing, the person partial image indicating the maximum best shot image for each person of the subject corresponding to each of the labels R1, R2,. Will be held.

  When the person partial image indicating the maximum best shot image of each person is obtained, the person partial image indicating the maximum best shot image for each person of the subject corresponding to each of the labels R1, R2,... Rs,. The background image stored in the processing memory 207 is combined into a single generated image (step S319), and the generated image is displayed on the display unit 202 for user confirmation (step S320). ).

  When the user confirms the generated image displayed on the screen of the display unit 202 and designates cancellation indicating that the generated image is not adopted by the key operation of the key operation unit 206 (NO in step S321), The generated image is canceled and it is confirmed whether or not to continue shooting (step S323). On the other hand, when an instruction is given to save the generated image (YES in step S321), the generated image is stored in the memory unit 205, so that the generated image is transferred to another application (transfer, printing, pasting to a document, etc.). Is set to a usable state (step S322), and it is confirmed whether or not to continue photographing (step S323). When shooting is continued (YES in step S323), the process returns to step S303, and the operations described above are repeated. On the other hand, when the shooting is to be ended (NO in step S323), the operations of the camera sensor 201 and the image processing unit 203 are ended (step S324), and the processing in FIG. 3 is ended (step S326).

(Description of operation of other embodiments)
Next, an operation example different from the flowchart of FIG. 3 will be described for the operation of the photographing apparatus shown in FIG.

  In this embodiment, the basic operation is the same as that in the flowchart of FIG. 3 described above, but the operation of acquiring a plurality of photographed images by pressing the shutter once is shown in the flowchart of FIG. This is not the case. That is, in the flowchart of FIG. 3, a predetermined number of photographed images are acquired by a shutter pressing operation. In this embodiment, at a predetermined time interval by a single shutter pressing operation. Unlike the case of FIG. 3, the user designates an arbitrary time as the image acquisition time due to a difference in the shutter pressing operation method and the like. FIG. 4 and FIG. 5 show an operation example that makes it possible to acquire a plurality of photographed images taken during the period.

  For example, the flowchart of FIG. 4 is a flowchart showing an example different from FIG. 3 of the flow of the person photographing process performed in the photographing apparatus of FIG. 2, and only steps S406 and s417 hatched with diagonal lines are illustrated. This is different from the flowchart of FIG. That is, the process is the same as each step in FIG. 3 except that step S406 is used in place of step S306 in the flowchart in FIG. 3 and step S417 is used in place of steps S307 and s318 in the flowchart in FIG. Steps S401 to S405, Steps S407 to S416, and Steps S418 to S425 are the same processes as Steps S301 to S305, Steps S308 to S317, and Steps S319 to S326 in the flowchart of FIG.

  In the flowchart of FIG. 4, the shutter operation is selectively used for the start shutter operation for instructing the start of shooting and the end shutter operation for instructing the end of shooting, and the start of instructing the start of shooting is performed as one shutter pressing operation. Two operations, a shutter pressing operation (operation in step S406) and an end shutter pressing operation for instructing the end of shooting (operation in step S417), are possible. That is, the user starts the captured image acquisition operation at an arbitrary timing by pressing the start shutter to instruct the start of shooting (step S406), and presses the end shutter to instruct the end of shooting. By performing the operation, photographing is terminated at an arbitrary timing (step S417). In this operation, the imaging apparatus enters the imaging mode when the shutter is pressed in the preview mode (imaging standby state), starts imaging, and returns to the preview mode when the shutter is pressed in this imaging mode.

  Therefore, as the image acquisition time, after the user performs the pressing operation of the start shutter for instructing the start of shooting (step S406), until the pressing operation of the end shutter for instructing the end of shooting is performed (step S406). S417), by continuously capturing images at predetermined time intervals and acquiring captured images, it is possible to acquire any number of captured images desired by the user. The same processing as in the flowchart of FIG. 3 is performed on each of a number of photographed images acquired between the start timing instructed in step S406 and the end timing instructed in step S417. The best shot image is extracted, synthesized with the background image, and output as one generated image.

  The flowchart of FIG. 5 is a flowchart showing an example different from FIGS. 3 and 4 of the flow of the person photographing process performed in the photographing apparatus of FIG. 2, and only the step S517 hatched with diagonal lines is shown. This is different from the flowchart of FIG. In other words, except that step S517 is used in place of steps S307 and s318 in the flowchart of FIG. 3, steps S501 to S506, steps S507 to S516, and steps S518 to S525 are the same. These are the same processes as steps S301 to S306, steps S308 to S317, and steps S319 to S326 in the flowchart of FIG.

  In the case of the flowchart of FIG. 5, as the shutter pressing operation, as in the case of the flowchart of FIG. 3, a shutter pressing (short pressing) operation for instructing acquisition of a plurality of photographed images having a predetermined number of image acquisitions. In addition to (operation of step S506), a shutter long press operation (operation of step S517) for instructing continuation of shooting can be performed, and the user can arbitrarily press the shutter to instruct the start of shooting. The captured image acquisition operation is started at the timing (step S506), and the captured image acquisition operation is continued while the shutter long press operation continues, and the shutter long press operation is canceled at an arbitrary timing to capture the image. Is terminated (step S517).

  Therefore, as the image acquisition time, while the user continues to press and hold the shutter for a long time, any number of images desired by the user can be obtained by continuously capturing images at predetermined time intervals. Can be obtained. FIG. 3 is a flowchart for each of an arbitrary number of photographed images acquired from the timing when the shutter pressing operation is performed in step S506 to the timing when the shutter long-press operation is canceled (NO in S517) to finish photographing in step S517. By performing the same processing as the above, the best shot images of each of a plurality of persons as subjects are extracted, combined with the background image, and output as one generated image.

  Further, regarding the setting of the number of subjects M, in the flowcharts of FIGS. 3 to 5, an example in which the user arbitrarily sets is shown. However, a person who is a subject from the photographed images is added to the photographing apparatus of FIG. 2. By incorporating a human detection unit capable of detection, it is possible to automatically detect a person as a subject, count the number of detected persons, and automatically set the number of subjects M. is there.

  In addition, when the same person is discriminated from the persons of the subject in the plurality of photographed images and labeling is performed for specifying each person, the photographing position is fixed for each person who becomes the subject, Discrimination of person partial images that exist at approximately the same coordinate position of the shot images as the same person, or the same person based on clothes, hats, and other patterns and shades of each person partial image Or by extracting facial parts and comparing the features obtained from the facial contours, relative positional relationships such as eyes, nose and mouth, etc., and distinguishing them as the same person. is there.

  In addition, as image processing in the image processing unit 203, when each person partial image is extracted from a plurality of photographed images for each person of the subject, It is also possible to perform color correction according to the characteristics of the person of each subject.

  As for the best shot degree calculation method, the best shot degree may be variably set according to the application and the scene. For example, when trying to use it for personal authentication, whether the best shot degree is set high or the front is simply faced for an image of a large face image or a high sharpness degree It is also possible to set the best shot degree based only on this.

  Further, the present invention can be applied even when the subject is only one person. In such a case, the processing may be performed with the number of subjects M described as the premise of the flowchart of FIG.

  As described in detail above, in the embodiment according to the present invention, the following effects can be obtained.

  The first effect is that when photographing a plurality of persons as subjects, the best image of each subject is extracted from a plurality of photographed images and combined with the background image. It is possible for all of them to generate images in a better state.

  The second effect is that a clearer human partial image interpolation process is performed using a plurality of photographed images, so that it is possible to generate an image with less deterioration due to camera shake or the like.

  The third effect is that it is possible to extract a best shot image of each subject and output a generated image synthesized with a background image only by software processing related to image processing. It can be realized by using the equipped image processing chip as it is.

  The configuration of the preferred embodiment of the present invention has been described above. However, it should be noted that such examples are merely illustrative of the invention and do not limit the invention in any way. Those skilled in the art will readily understand that various modifications and changes can be made according to a specific application without departing from the gist of the present invention.
