CPC H04N 19/107 (2014.11) [H04N 19/105 (2014.11); H04N 19/137 (2014.11); H04N 19/176 (2014.11); H04N 19/423 (2014.11)] | 7 Claims |
1. A moving-picture decoding device comprising:
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;
a temporal motion information candidate derivation unit configured to derive a temporal motion information candidate from motion information of a block neighboring a decoding target block in a time domain; and
a history-based motion information candidate derivation unit configured to derive a history-based motion information candidate from a memory for retaining motion information of a decoded block,
wherein the history-based motion information derivation unit is configured to add the temporal motion information candidate to a motion information candidate list without comparison between the spatial motion information candidate and the temporal motion information candidate with respect to the motion information, and to add the history-based motion information candidate to the motion information candidate list in case that the motion information of the spatial motion information candidate and the motion information of the history-based motion information candidate are not identical.
