Abstract
In order to provide efficient coding technology with a low load, a 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, 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 temporal motion information candidate is compared with neither the spatial motion information candidate nor the history-based motion information candidate with respect to the motion information.
