A query acquisition unit () acquires a query video. A query frame selection unit () selects a plurality of query frames from among a plurality of first frame images included in the query video. A video selection unit () selects a video by using the plurality of query frames. At this time, the video selection unit () uses references (1) and (2) below as a condition for selecting the video. Reference (1) A condition that a “similar frame image whose degree of similarity to a query frame satisfies a first reference is present” is satisfied for at least two query frames. Reference (2) When query frames associated with each of at least two similar frame images are arranged in the same order as that of the at least two similar frame images, the arrangement order coincides with an arrangement order of at least two query frames in a query video.
