wherein the scores set to the plurality of second images are lower than the score set to the first image.
2. The apparatus according to claim 1 , further comprising a development circuit configured to develop the captured image, the development circuit developing the the plurality of second images under a condition different from that for the first image.
3. The apparatus according to claim 1 , wherein the image capturing instruction of the user is performed by input of a predetermined voice command.
4. The apparatus according to claim 1 , wherein the image capturing instruction of the user is performed via an external apparatus capable of communicating with the image capturing apparatus.
5. The apparatus according to claim 1 , wherein a supervised value of each of the plurality of second images is determined such that the larger a difference between an image capturing condition of the first image and that of each of the plurality of second images becomes, the larger a difference between a supervised value of the first image and that of each of the plurality of second images becomes.
6. The apparatus according to claim 1 , wherein a supervised value of each of the plurality of second images is determined such that the larger a difference between a shutter timing of the first image and that of each of the plurality of second images becomes, the larger a difference between a supervised value of the first image and that of each of the plurality of second images becomes.
7. The apparatus according to claim 1 , wherein the control circuit registers at least some of the plurality of second images as negative supervised data.
8. The apparatus according to claim 7 , wherein the control circuit registers, as the negative supervised data, an image of the plurality of second images, whose similarity to the first image is lower than a threshold.
9. The apparatus according to claim 1 , wherein the plurality of second images are images captured by changing an image capturing condition of the first image and at least one of conditions of focus, exposure, white balance, strobe light emission, and zoom.
10. The apparatus according to claim 1 , wherein the plurality of second images are generated from a moving image captured immediately before or immediately after the first image capturing performed.
11. The apparatus according to claim 1 , wherein the plurality of second images are continuously shot images captured immediately before or immediately after capturing the first image capturing performed.
12. The apparatus according to claim 1 , wherein the image capturing device captures the plurality of second images using an electronic shutter.
13. The apparatus according to claim 1 , wherein when the number of supervised data is smaller than a predetermined number, the control circuit causes the image capturing device to capture the plurality of second images.
14. The apparatus according to claim 1 , wherein
in a vector formed by combining feature amounts of input layers of the neural network, if a difference between data of the first image and data of each of the plurality of second images is not less than a predetermined value, the plurality of second images are not used as the supervised data.
