Patent ID: 7192141

Claim:
A color projection system for projecting an image on a screen, comprising at least one light source for emitting a white light beam, a light splitting means for splitting said white light beam into color subbeams each comprising light of a different wavelength or wavelength range, for each of said color subbeams a light modulating means, and a dichroic prism for recombining said color subbeams, each of said modulating means positioned adjacent to a side of said dichroic prism, wherein said color projection system furthermore comprises further optical components for imaging each of said color subbeams onto the relevant light modulating means such that the images of each of said color subbeams on the corresponding light modulating means have a substantially equal size and such that the images of each of said color subbeams on the screen have the same orientation and such that for an image representing a plane of equal color, the distance between the average color coordinates in the 1976 CIE Chromaticity Diagram for the ANSI-points at the left side of the image on the screen and for the ANSI-points at the right side of the image on the screen is smaller than 0.01.
