Abstract: A prediction information deriving unit derives the inter-prediction information candidates from inter-prediction information of a prediction block neighboring to a coding target prediction block or a prediction block present at the same position as or near the coding target prediction block in a coded picture at a temporally different position from the coding target prediction block. A candidate supplementing unit supplements inter-prediction information candidates having the same prediction mode, reference index, and motion vector until the number of inter-prediction information candidates reaches the designated number of candidates when the number of inter-prediction information candidates is smaller than the designated number of candidates.

Abstract: A motion vector decoding unit derives a motion vector of a prediction block subject to decoding on the basis of a motion vector of a candidate block included in candidate blocks selected from neighboring blocks. The motion compensation prediction unit performs motion compensation prediction using the derived motion vector. In case a motion vector number of a first block and a motion vector number of a second block are identical with each other, the motion vector decoding unit determines whether or not to set the second block as a candidate block in accordance with whether or not a reference index indicating a reference picture that the motion vector of the first block refers to and a reference index indicating a reference picture that the motion vector of the second block refers to are identical with each other.

Abstract: A picture coding device includes: a block vector candidate derivation unit that derives block vector candidates of a coding target block in a coding target picture from coding information stored in a coding information storage memory; a selector that selects a selected block vector from the block vector candidates; a storage that stores coded pictures of a predetermined number of intra block copy standard blocks immediately before the coding target block; and a reference region boundary correction unit that removes a coded picture of one intra block copy standard block in the storage from a referenceable region after completion of a coding process of the coding target block, and determines whether an upper left position and a lower right position of a reference block indicated by the selected block vector are both included in the referenceable region.
