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.
