Abstract
In order to provide low-load, efficient coding technology, a moving-picture decoding device includes a spatial motion information candidate derivation unit configured to derive a spatial motion information candidate from motion information of a block neighboring a decoding target block in a space domain and a history-based motion information candidate derivation unit configured to derive a history-based motion information candidate from a memory where motion information of a decoded block is retained, wherein the history-based motion information candidate derivation unit preferentially derives old motion information without making a comparison of the motion information with the spatial motion information candidate.
