摘要

When information, which indicates whether or not coupled motion information candidates to be used in common are to be derived with respect to all prediction blocks within a coding block, indicates that the coupled motion information candidates to be used in common are to be derived with respect to all of the prediction blocks within a coding block, a coupled motion information candidate list generating unit (140) derives a plurality of coupled motion information candidates to be used in common with respect to all of the prediction blocks within a coding block. A coupled motion information selecting unit (141) selects one coupled motion information candidate from the plurality of coupled motion information candidates, and uses the one coupled motion information candidate that was selected in a prediction block to be encoded.
