摘要

Provided is an image encoding method and an image decoding method wherein encoding efficiency can be improved. A motion-video encoding apparatus (100) is provided with a merge-block candidate calculation unit (111) that specifies merge-block candidates for a merge mode, using motion vectors and reference picture indices used in blocks adjacent to the block to be encoded, and using colPic information such as a motion vector of a co-located block stored in a colPic memory (112). The merge-block candidate calculation unit (111) also generates a combined merge block using the merge-block candidates.
