APPARATUS, METHOD AND PROGRAM FOR ENCODING MOVING IMAGE

摘要

PROBLEM TO BE SOLVED: To suppress processing load and improve coding efficiency of motion information when encoding is performed by using motion information of an adjacent block.

SOLUTION: A coupling motion information candidate list generation part 1000 calculates motion information of a plurality of encoded adjacent blocks adjacent to an encoding target block as a motion information candidate of the encoding target block to create a motion information candidate list. A coupling motion information candidate list deletion part 1001 deletes either motion information from the candidate list when there is the coincidence of a prediction direction and a motion vector value among motion information included in the created candidate list. A encoding part encodes the encoding target block and an index representing designated reference block by using motion information of the designated reference block obtained from the candidate list processed in the coupling motion information candidate list deletion part 1001 when a coupling prediction mode is selected.
