Patent ID: 7265778

Claim:
A method of characterizing a display having a plurality of color channels and unknown chromaticities of the color channels, the method implemented at least in part by a computer, and the method comprising the steps of: a) visually characterizing the nonlinearities of the display; b) visually determining luminance ratios of the color channels based at least upon input received from a user interface, heterochromatic photometry and the characterized nonlinearities; c) visually determining the chromaticities of the color channels using a neutral identification process and the determined luminance ratios of the color channels; d) calculating a colorimetric mixing matrix for the display, said calculating further comprising combining the luminance ratios of the color channels determined in step b with the chromaticities of the color channels determined in step c; and e) generating a characterization of colorimetric properties of the display using the colorimetric mixing matrix.
