Representing an extended color gamut digital image in a limited color gamut color space

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 including providing a color adjustment function; 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 using the color adjustment function; representing the limited color gamut digital image in the storage color space; and associating information about the color adjustment function with the limited color gamut digital image in the storage color space such that the associated information and the limited color gamut digital image are adapted to produce a reconstructed extended color gamut digital image.
