Patent abstract

Provided are an image encoding/decoding method and apparatus, in which one of a plurality of color component images of an input image is predicted from a different color component image using a correlation between the color component images and the encoding order of the plurality of color component images is adaptively determined according to the characteristics of the input image. In the image encoding method and apparatus, prediction errors or the amounts of generated bits for the remaining color component images predicted using a previously encoded color component image according to encoding orders are compared to determine the optimal encoding order and encoding is performed using a correlation between the color component images according to the determined encoding order.
