1. An image selection apparatus comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to perform operations comprising:
acquiring a query video including a plurality of first frame images;
selecting a plurality of query frames from among the plurality of first frame images, wherein the plurality of query frames are selected by repeatedly performing a process of selecting, as a query frame following a first of the query frames, the first frame image having a change amount from the first query frame equal to or greater than a predetermined reference; and
selecting a video by using the plurality of query frames, based on at least first and second conditions for selecting the video, wherein
the first condition is that a similar frame image having a degree of similarity to the query frame satisfies a first reference is present for at least two of the query frames,
the second condition is that, in a case in which the query frames associated with each of at least two similar frame images are arranged in a same order as that of the at least two similar frame images, an arrangement order of the at least two similar frame images coincides with an arrangement order of the at least two query frames in the query video.
