Title
(EN) COLOR RENDERING OF ILLUMINATION LIGHT IN DISPLAY SYSTEMS
(FR) RENDU DE COULEURS D'UNE LUMIERE D'ECLAIRAGE DANS DES SYSTEMES D'AFFICHAGE
Abstract
(EN) A method and apparatus for compensating for deficiency in the illumination light from a light source (102) is provided, where the spectrum in the visible range of light from the light source is determined, and a deficiency at a wavelength or band of wavelengths in the visible range of light is determined therefrom, a color sequencing device is provided having a set of filters (106) comprising red, green and blue filter segments, and an additional color balancing filter segment, and wherein a the color balancing segment is constructed so as to preferentially pass a band or bands of wavelengths, which band or bands are determined based on the determined deficiency of the light source.
(FR) L'invention concerne un procédé et un appareil de compensation d'une lacune dans une lumière d'éclairage émise d'une source lumineuse. Le spectre du rayonnement visible de la lumière émise de la source lumineuse est déterminé, et une lacune au niveau d'une longueur d'onde ou d'une bande de longueurs d'onde dans le rayonnement visible de la lumière en est déduite. Un dispositif de séquencement des couleurs est mis en oeuvre qui comprend un ensemble de filtre présentant des segments de filtre rouge, vert et bleu, et un segment de filtre d'équilibrage des couleurs supplémentaire. Le segment d'équilibrage des couleurs est construit de façon à traverser, de préférence, une bande ou des bandes de longueurs d'onde, laquelle (lesquelles) est (sont) déterminée(s) sur la base de la lacune détectée de la source lumineuse.
