Information processing apparatus, method, and storage medium storing a program that obtain a feature amount from a frame in accordance with a specified priority order

A method executed by an information processing apparatus, the method comprising:

• executing processing for obtaining a first feature amount for each of a plurality of frames;
• specifying a priority order of frames for obtaining a second feature amount different from the first feature amount based on the obtained first feature amount;
• executing processing for obtaining the second feature amount from a frame in accordance with the specified priority order;
• and
• selecting an image processing target frame on the basis of the obtained second feature amount, wherein the number of frames from which the second feature amount is obtained is fewer than the number of the plurality of frames from which the first feature amount is obtained.

A method executed by an information processing apparatus, the method comprising:

• executing processing for obtaining a first feature amount for each of frames in each of sections divided;
• executing processing for obtaining a second feature amount different from the first feature amount for a portion of the frames included in each of the sections;
• specifying, in each of the sections, candidate frames for obtaining the second feature amount, based on the obtained first feature amount and the second feature amount obtained from the portion of the frames, wherein the number of the candidate frames is fewer than the number of the frames;
• executing processing for obtaining the second feature amount from the candidate frames;
• and
• selecting an image processing target frame based on the second feature amount of the candidate frames.
