Image candidate determination apparatus, image candidate determination method, program for controlling image candidate determination apparatus, and recording medium storing program
In a case where a plurality of images are input, images in which the same person is included are grouped. In a case where there are images of which the number is equal to or larger than a maximum number of images to be made public for the same person, a total image evaluation value is calculated for the images in which the same person is included. An image with a small total image evaluation value is determined as a private image candidate so that the number thereof is smaller than the maximum number.
1. An image candidate determination apparatus comprising:
a processor configured to
receive a plurality of images and group one or more images in which the same person is included as grouped images, and
determine at least one extraction image candidate or at least one non-extraction image candidate from the grouped images, on the basis of a total image evaluation value and a limit value of an extraction number of images in which the same person is included,
wherein the total image evaluation value is calculated for each image on the basis of a person image evaluation value calculated for each person who appears in the images.
2. The image candidate determination apparatus according to claim 1 ,
wherein the processor is configured to display the extraction image candidate or the non-extraction image candidate on a display screen.
3. The image candidate determination apparatus according to claim 1 ,
wherein the person image evaluation value is calculated on the basis of an evaluation value relating to at least a face,
wherein the processor is configured to extract a face image portion from each of a plurality of images,
group the face image portions for each face image portion of the same person as the grouped images, and
determine the extraction image candidate or the non-extraction image candidate from the grouped images, on the basis of the total image evaluation value and the limit value of the extraction number of images in which the same person is included.
4. The image candidate determination apparatus according to claim 2 ,
wherein the person image evaluation value is calculated on the basis of an evaluation value relating to at least a face,
wherein the processor is configured to
extract a face image portion from each of a plurality of images as the grouped images,
group the face image portions for each face image portion of the same person, and
determine the extraction image candidate or the non-extraction image candidate from the grouped images, on the basis of the total image evaluation value and the limit value of the extraction number of images in which the same person is included.
5. The image candidate determination apparatus according to claim 1 ,
wherein the processor is configured to correct the person image evaluation value using a correction coefficient for setting the person image evaluation value to be larger as the number of images in which the same person is included is smaller.
6. The image candidate determination apparatus according to claim 2 ,
wherein the processor is configured to correct the person image evaluation value using a correction coefficient for setting the person image evaluation value to be larger as the number of images in which the same person is included is smaller.
7. The image candidate determination apparatus according to claim 1 ,
wherein the processor is configured to display a number of images for each person included in the extraction image candidate or the non-extraction image candidate on the display screen.
8. The image candidate determination apparatus according to claim 2 ,
wherein the processor is configured to
determine at least one extraction image or at least one non-extraction image from the extraction image candidate displayed on the display screen, or
determine at least one non-extraction image or at least one extraction image from the non-extraction image candidate displayed on the display screen.
9. The image candidate determination apparatus according to claim 8 , further comprising:
a display that notifies the number of the at least one extraction image or the number of the at least one non-extraction image, for each person included in the images.
10. The image candidate determination apparatus according to claim 8 ,
wherein the image candidate determination apparatus further comprises: a display that updates and notifies the number of at least one extraction image or the number of at least one non-extraction image for each person included in the images in accordance with the determination of the extraction images or the non-extraction images.
11. The image candidate determination apparatus according to claim 1 ,
wherein the processor is configured to exclude, in a case where an extraction number of images in which a specific person is included deviates from a limit value as one non-extraction image candidate becomes a non-extraction image or one extraction image candidate becomes an extraction image, the one non-extraction image candidate or the one extraction image candidate from the non-extraction image candidate or the extraction image candidate.
12. The image candidate determination apparatus according to claim 1 ,
wherein the processor is configured to regard non-same person as the same person for adults, and group the one or more images in which the same person is included.
13. The image candidate determination apparatus according to claim 1 ,
wherein the processor is configured to calculate a lower person image evaluation value as the number of persons included in an image is larger.
14. The image candidate determination apparatus according to claim 1 ,
wherein the processor is configured to determine, on the basis of the total image evaluation value and the limit value of the extraction number of images in which the same person is included, the extraction image candidate or the non-extraction image candidate from the grouped images so that an extraction number of images in which the same person is included is within the limit value.
15. The image candidate determination apparatus according to claim 1 ,
wherein the processor is configured to
detect a person for which the number of the same person included in the grouped images is equal to or smaller than a threshold value as a detected person, and
perform an imaging instruction of the detected person.
16. An image candidate determination method comprising:
receiving a plurality of images and grouping one or more images in which the same person is included as grouped images; and
determining at least one extraction image candidate or at least one non-extraction image candidate from the grouped images, on the basis of a total image evaluation value and a limit value of an extraction number of images in which the same person is included,
wherein the total image evaluation value is calculated for each image on the basis of a person image evaluation value calculated for each person who appears in the images.
17. A non-transitory computer-readable recording medium storing a program for controlling a computer of an image candidate determination apparatus to execute:
receiving a plurality of images and grouping one or more images in which the same person is included as grouped images; and
determining at least one extraction image candidate or at least one non-extraction image candidate from the grouped images, on the basis of a total image evaluation value and a limit value of an extraction number of images in which the same person is included,
wherein the total image evaluation value is calculated for each image on the basis of a person image evaluation value calculated for each person who appears in the images.
