摘要：
A method for determining information parameter(s) useful in processing a digital image having color values with an extended color gamut, includes the steps of: adjusting the color values of the extended color gamut digital image to fit within a limited color gamut to form a limited color gamut digital image; determining a residual image representing a difference between the extended color gamut digital image and the limited color gamut digital image; and analyzing the residual image to determine one or more image information parameter(s) related to the information contained in the residual image such parameter(s) being useful in processing the digital image.
