摘要

A coupled motion information calculating unit (906) calculates, as candidates of a spatial motion information candidate of a block to be encoded, motion information of multiple already encoded adjacent blocks in prescribed positions spatially adjacent to the block to be encoded and, if the candidates of the spatial motion information candidate include candidates that have identical motion information, then one of these is set as the spatial motion information candidate. The motion information of an already encoded block in a picture temporally different from the picture having the block to be encoded is utilized to calculate a temporal motion information candidate of the block to be encoded. Thus, motion information candidates include the spatial motion information candidate and the temporal information candidate.
