Abstract
A method for representing a digital image having color values with an extended color gamut in a storage color space having a limited color gamut includes adjusting the color values of the extended color gamut digital image to fit within the limited color gamut to form a limited color gamut digital image; representing the limited color gamut digital image in the storage color space; determining a set of residual images representing a difference between the extended color gamut digital image and the limited color gamut digital image; and associating the set of residual images with the limited color gamut digital image in the storage color space such that the associated residual images and the limited color gamut digital image is adapted to be used to form a reconstructed extended color gamut digital image.
