Abstract
A moving-picture coding device, for performing an affine transform in units of coding blocks and forming a bitstream, includes a subblock-based temporal merging candidate derivation unit configured to derive a subblock-based temporal merging candidate which comprises a motion vector and a flag indicating whether or not a prediction subblock is valid for each reference list in units of subblocks, an affine inheritance merging candidate derivation unit configured to derive an affine inheritance merging candidate for inheriting an affine model of blocks neighboring a coding target block in a space domain, and an affine construction merging candidate derivation unit configured to derive an affine construction merging candidate from a plurality of motion information elements of blocks neighboring the coding target block in a space or time domain.
