Abstract
An intra prediction apparatus includes: a candidate narrowing-down unit 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 which executes intra prediction in the intra prediction direction narrowed down by said candidate narrowing-down unit. Through this, computational load can be lightened while contributing to improvement in picture quality and encoding efficiency.
