摘要

PROBLEM TO BE SOLVED: To suppress a processing load in performing encoding by using motion information of an adjacent block.

SOLUTION: A combined motion information candidate list generation unit 1100 generates a motion information candidate list in which respective motion information included in each of a plurality of blocks spatially or temporally adjacent to an encoding target prediction block is registered as motion information candidates. A prediction error encoding unit 103 calculates a prediction error signal of the encoding target prediction block and encodes the signal, by using a motion information candidate selected from the motion information candidate list as motion information of the encoding target prediction block. A motion information encoding unit 110 encodes an index indicating the motion information candidate selected from the motion information candidate list. The combined motion information candidate list generation unit 1100 sets designation information of a reference image included in the motion information candidate to the same value, in an encoding target prediction block whose size is equal to or smaller than a predetermined size.
