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.

A method of characterizing a display having a plurality of color channels, comprising the steps of:
- a) visually characterizing the nonlinearities of the display;
- b) determining luminance ratios of the color channels using heterochromatic photometry;
- c) determining the chromaticities of the color channels using a neutral identification process;
- and
- d) calculating a calorimetric mixing matrix for the display by combining the luminance ratios of the color channels determined in step b with the chromaticities of the color channels determined in step c.
