METHOD AND APPARATUS FOR ENCODING/DECODING COLOR IMAGE

摘要

The present invention relates to a method and an apparatus for encoding/decoding a color image. The apparatus for encoding an image: encodes a luminance component block for a current block of the image, selects one among plural color formats to encode a chrominance component block for the current block of the image according to the selected color format, and generates and outputs a bit stream including the information on the encoded luminance component block, the encoded chrominance component block, and the selected color format. The invention enables an improvement in compression performance by encoding and decoding one image which constitutes a video in various color formats.
