The present invention provides a video search device and/or the like for accomplishing video searches in which a user easily specifies the position, orientation and/or the like of an object that should appear in a video. In a video search device (501), a receiver (502) receives input of a still image, two reference positions in the still image and two target positions in a video frame. An extractor (503) extracts a reference image containing the two reference positions from the still image. A searcher (504) searches for similar frame images in which local images similar to the reference image are depicted, from frame images included in the video, traces two movement tracks of two noteworthy pixels depicted at start positions corresponding to the two reference positions in a local image when time advances or regresses from a similar frame image in the video, searches for a target frame image where the two movement tracks approach two target positions and produces as search results videos containing the similar frame image and the target frame image. |
