摘要

PROBLEM TO BE SOLVED: To provide a technique for improving coding efficiency by performing block division suitable for image coding and decoding. SOLUTION: A merge candidate list construction unit for constructing a merge candidate list, a first merge candidate selection unit for selecting a first merge candidate which is a simple prediction corresponding to a first merge partition from the merge candidate list, and a merge candidate selection unit. It comprises a second merge candidate selection section that selects a second merge candidate that is a simple prediction corresponding to the second merge partition from the merge candidate list, and both the first merge partition and the second merge partition The motion information of the included block is stored as the simple predicted motion information of either the first merge candidate or the second triangular merge candidate.
