INTRA PREDICTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an intra prediction apparatus which is capable of lightening computational load while contributing to improvement in picture quality and encoding efficiency.

SOLUTION: An intra prediction apparatus 11 includes: a candidate narrowing-down unit 111 which narrows down, from a plurality of intra prediction directions, an intra prediction direction candidate which is applied to a block of multiple pixels that constitutes a video in accordance with a characteristic of the video; and an intra prediction execution unit 112 which executes intra prediction in the intra prediction direction narrowed down by the candidate narrowing-down unit 111. Through this, computational load can be lightened while contributing to improvement in picture quality and encoding efficiency.
