摘要

A merging motion information candidate generation unit 140 derives, when information indicating whether or not to derive a merging motion information candidate shared for all prediction blocks in a coding block is information indicating the derivation of a merging motion information candidate shared for all the prediction blocks in the coding block, a plurality of merging motion information candidates shared for all the prediction blocks in the coding block. A merging motion information selection unit 141 selects one merging motion information candidate from the plurality of merging motion information candidates and uses the selectedmergingmotion information candidate in a predict ion block subject to coding.
