A video search device for video searches in which a user specifies the position and orientation of an object that should appear in a video. A receiver receives input of a still image, two reference positions in the still image and two target positions in a video frame. An extractor extracts a reference image containing the two reference positions from the still image. A searcher searches for similar frame images in which local images similar to the reference image are depicted, from frame images in the video, traces movement tracks of two noteworthy pixels 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 videos containing the similar frame image and the target frame image.
