Abstract
A picture coding device, for coding a moving picture using inter prediction based on inter prediction information in units of blocks into which each picture of moving pictures is divided and forming a bitstream, includes a coding information storage unit configured to add the inter prediction information used in the inter prediction to a history-based motion vector predictor candidate list, a spatial motion vector predictor candidate derivation unit configured to derive a spatial motion vector predictor candidate from a block neighboring a target block and add the spatial motion vector predictor candidate to a motion vector predictor candidate list, and a temporal motion vector predictor candidate derivation unit configured to derive a temporal motion vector predictor candidate from a block located at the same position as or near the target block and add the temporal motion vector predictor candidate to the motion vector predictor candidate list.
