Abstract:
1. A system for displaying images with the aid of a spatial light modulator wherein the system comprises: a light source emitting an illumination beam; the spatial light modulator comprising a matrix of pixels controlled by video control signals corresponding to a succession of image frames to be displayed; a matrix filter formed of a mosaic of adjacent elementary filters of various colors, illuminated by said illumination beam and transmitting a spatially filtered color beam to the spatial light modulator, means for producing an image of said filter on an entrance face of the spatial light modulator; means of displacement for displacing said image of the filter on the entrance face of the spatial light modulator and a device for controlling these means of displacement, making it possible to control at least one sequence of displacements of the image of the filter during each image frame.
