Abstract: An object detection unit detects an object of interest from within frames of video acquired from an image capturing unit. A motion vector detection unit detects a motion vector of the object between the frames of the video. A cutout position determination unit determines a cutout position for cutting out an image of a predetermined size from each frame of the acquired video.

An image composition unit combines image data of the object cut out from the object cutout position with image data of a background cut out from the background cutout position excluding the object.
