Title:
画像復号装置、画像復号方法及びプログラム
Document Type and Number:
Japanese Patent JP6931038
Kind Code:
B2
Abstract:
An image decoding device (200) includes: a merge unit (241A2) configured to apply geometric block partitioning merge to a target block divided in a rectangular shape, wherein the merge unit (241A2) includes: a merge mode specifying unit (241A21) configured to specify whether or not the geometric block partitioning merge is applied; a geometric block partitioning unit (241A22) configured to specify a geometric block partitioning pattern and further perform geometric block partitioning on the target block divided in the rectangular shape by using the specified geometric block partitioning pattern; and a merge list construction unit (241A23) configured to construct a merge list for the target block subjected to the geometric block partitioning and decode motion information.
