Abstract
Provided are an image encoding/decoding method and apparatus, in which one of a plurality of color component images is predicted from a different color component image reconstructed using a correlation between the plurality of color component images. Using a reconstructed image of a first color component image selected from among the plurality of color component images forming a single color image, the other color component images are predicted.
Claims12
An image decoding method comprising:
- (a) receiving a bitstream of an encoded image including a plurality of color component images;
- (b) decoding a pixel block having a predetermined size of a first color component image among the color component images;
- and
- (c) decoding a corresponding pixel block of a second color component image using pixel values of a decoded neighbor pixel block of the previously processed first color component image, pixel values of a decoded neighbor pixel block of the second color component image, and pixel values of the decoded pixel block of the first color component image.

An image decoding apparatus comprising:
- a first color component decoding unit which receives a bitstream including a plurality of encoded color component images comprising a plurality of color components and decodes a pixel block having a predetermined size of a first color component image among the color component images;
- and
- a correlation decoding unit which decodes a corresponding pixel block of a second color component image using pixel values of a decoded neighbor pixel block of the previously processed first color component image, pixel values of a decoded neighbor pixel block of the second color component image, and pixel values of the decoded pixel block of the first color component image.
