    摘要: Technology for improving coding efficiency by performing a block split suitable for picture coding and decoding is provided. A moving-picture coding device for performing an affine transform in units of coding blocks includes 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, 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, and an affine fixation merging candidate derivation unit configured to derive an affine fixation merging candidate in which motion information of an affine control point is fixed. A motion vector of each affine control point is fixed to (0, 0) in the affine fixation merging candidate.

    摘要: 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.
