Abstract
A picture coding device, for coding a moving picture using inter prediction based on inter prediction information in units of blocks and forming a bitstream, includes a coding information storage unit configured to store inter prediction information used in the inter prediction of a coded block in a history-based motion vector predictor candidate list, a spatial merging candidate derivation unit configured to derive a spatial merging candidate from inter prediction information of a block spatially neighboring a coding target block and to add the spatial merging candidate to a merging candidate list, and a history-based merging candidate derivation unit configured to derive a history-based merging candidate from the inter prediction information stored in the history-based motion vector predictor candidate list and to add the history-based merging candidate to the merging candidate list.
