PROBLEM TO BE SOLVED: To improve encoding efficiency of a motion vector.SOLUTION: A candidate list generating section selects a plurality of blocks having one or two pieces of motion information comprising at least motion vector information and reference image information from a plurality of encoded blocks adjacent to a block to be encoded, and generates a candidate list comprising candidates of the motion information used in motion compensation prediction from the motion information of the selected block. A first motion information acquiring section acquires motion information of a first prediction list from a first candidate included in the candidates. A second motion information acquiring section acquires motion information of a second prediction list from a second candidate included in the candidates. A selected candidate generating section combines the motion information of the first prediction list acquired by the first motion information acquiring section, and the motion information of the second prediction list acquired by the second motion information acquiring section, to generate a new candidate of the motion information.
