VIDEO DECODING DEVICE, VIDEO DECODING METHOD, AND VIDEO DECODING PROGRAM

摘要

PROBLEM TO BE SOLVED: To improve encoding efficiency of motion information while suppressing a processing load when performing encoding using motion information of adjacent blocks.SOLUTION: Merge motion information candidate list generation units 1000 and 1001 calculate motion information of a plurality of decoded adjacent blocks adjacent to a block to be decoded as motion information candidates for the block to be decoded to generate a motion information candidate list. When motion vector values of first prediction match each other and motion vector values of second prediction match each other between two motion information candidates included in the generated candidate list irrespective of uni-prediction or bi-prediction, a merge motion information candidate list deletion unit 1002 deletes any one motion information candidate of the two motion information candidates from the candidate list.
