Abstract

Official abstract text for this publication.

A method and apparatus for determining an intra prediction mode of a coding unit. Candidate intra prediction modes of a chrominance component coding unit, which includes an intra prediction mode of a luminance component coding unit, are determined, and costs of the chrominance component coding unit according to the determined candidate intra prediction modes are compared to determine a minimum cost intra prediction mode to be the intra prediction mode of the chrominance component coding unit.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus for decoding an image, the apparatus comprising: an entropy decoder which obtains first information that indicates an intra prediction mode of a luminance block and second information that indicates an intra prediction mode of a chrominance block corresponding to the luminance block, from a bitstream; and an intra prediction performer that performs intra prediction on the luminance block according to the intra prediction mode of the luminance…
