METHOD FOR CORRECTING CHROMATICITY AND LUMINANCE DEFECTS OF A MATRIX SCREEN AND MATRIX SCREEN AND CIRCUIT IMPLEMENTING SUCH A METHOD

摘要

The present invention relates to a method for correcting chromaticity and luminance faults in images formed by a projector, in particular a projector using matrix screens, consisting in recording in at least one memory, at least one compensation table for said faults and to multiply, pixel by pixel, the video signals Rin, Gin and Bin coming from the color decoder, by the content of the memory card.
