ABSTRACT:
A method of characterizing a display having a plurality of color channels includes the steps of visually characterizing the nonlinearities of the display; determining luminance ratios of the color channels using heterochromatic photometry; determining the chromaticities of the color channels using a neutral identification process; and calculating a colorimetric mixing matrix for the display by combining the luminance ratios of the color channels with the chromaticities of the color channels.
