発明の概要(英語)

[Problem] To increase inter-predict coding efficiency and reduce data size. [Solution] Included are: a step of extracting, from a plurality of blocks which are present at a site corresponding to the sub-block and the periphery thereof in an already coded prior frame, one or more candidate reference blocks being highly related within the plurality of blocks

a step of selecting, from the extracted one or more candidate reference blocks, the block which most closely approximates the sub-block to be coded as the reference block

a step of generating a second reference pixel according to a pre-regulated plurality of added predict modes on the basis of a plurality of pixel values which configure the selected reference block

a step of generating a second predict pixel according to an already defined intra-predict mode on the basis of the second reference pixel

and a step of executing a rate distortion optimization on the basis of the second predict pixel.
