Patent ID: 7515746

Claim:
A method of color matching images generated by multiple projectors of a tiled projection display system, comprising the steps of: providing at least two projectors, each having chromaticity data representing a color gamut of that projector stored therein, and having luminance data representing the relative luminance of colors generated by that projector stored therein; communicating each projector's stored chromaticity and luminance data to a main controller; determining a standard color gamut achievable by each said projector; calculating color correction data for each projector, based on that projector's stored chromaticity data, luminance data, and on said standard color gamut; and calculating image pixel values based on input image data and said color correction data; wherein said determining and calculating color correction data steps are performed by at least one component selected from the group consisting of: a processing system in data communication with each projector, and at least one projector functioning at least partially as the main controller.
