Abstract:
A method for processing an extended color gamut digital image so as to represent the extended color gamut digital image in a storage color space having a limited color gamut digital image and for paying for such processed digital image, comprising the steps of:a) a user sending or authorizing the sending of an extended color gamut digital image to a processing site where the extended color gamut digital image is to be processed; b) processing such extended color gamut digital image at the processing site by: i) 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; ii) representing the limited color gamut digital image in the storage color space; iii) determining one of more residual images representing differences between the extended color gamut digital image and the limited color gamut digital image; and iv) associating the one of or more residual image(s) with the limited color gamut digital image in the storage color space such that the associated residual image(s) and the limited color gamut digital image are adapted to be used to form a reconstructed extended color gamut digital image; c) the user making payment; and d) making the processed extended color gamut digital image available to the user via a communications network.
