Patent ID: 8014026

Claim:
An image encoding system comprising: a residue production unit to generate first residues corresponding to differences between color components of a current image and color components of a predicted image; a residue prediction unit to predict second residues with respect to the first residues, the predicted second residues corresponding to color components other than a first color component by using a reconstructed first residue of the first color component reconstructed from a processing of a first residue of the first color component generated by the residue production unit; an encoding unit to encode the first residue of the first color component and the second residues of the color components other than the first color component; and an operation unit to predict a second residue of the first color component based on the reconstructed first residue of the first color component for a current pixel and reconstructed first residues of the first color component for one or more other pixels, wherein the residue prediction unit applies the predicted second residue of the first color component to the first residues corresponding to the color components other than the first color component.
