Classification: CPC G  H | IPC G  H

Claim 20:
21. A method for determining target display specific color adjustments, the method comprising:
identifying target display characteristics of a target image display, the target display characteristics of the target image display including a target spectral power distribution (SPD) of the target image display;
identifying reference display characteristics of a reference image display, the reference display characteristics of the reference image display including a reference SPD of the reference image display;
based at least in part on the target SPD, a set of sample colors and the viewer's color matching function (CMF) as determined with the method of claim 1, generating a set of target tristimulus values for the viewer for the set of sample colors as represented in the target image display;
based at least in part on the reference SPD, the set of sample colors and the viewer's color matching function (CMF), generating a set of reference tristimulus values for the viewer for the set of sample colors as represented in the reference image display;
generate a target display color transformation to transform the set of reference tristimulus values to the set of target tristimulus values; and
causing the target display color transformation to be used in image rendering operations of the target image display.
