A signal processing apparatus includes: a specification unit configured to specify, based on plural pixels forming the target block, a partial region which is a part of the target block; a search-region shifting unit configured to sequentially shift, within the reference frame a search region which is compared with the partial region; a comparing unit configured to calculate a degree of coincidence between the search region and the partial region, and to specify a coincidence region which is the search region having the highest degree of coincidence with the partial region, as the search region is shifted; and a detecting unit configured to detect the motion vector of the target block based on both positions of the partial region within the target frame ad the coincidence region within the reference frame.
