Title
(EN) COLOR RENDERING OF ILLUMINATION LIGHT IN DISPLAY SYSTEMS
(FR) RENDU DES COULEURS DE LUMIERE D'ECLAIRAGE DANS DES SYSTEMES D'AFFICHAGE
Abstract
(EN) A method and a color rendering filter for compensating for deficiency in illumination light from a light source in display systems are provided. The color rendering filter has a color that is determined based upon the spectrum, sensitivity of viewer's eyes over the visible light range, and a pre-determined waveband threshold.
(FR) La présente invention concerne un procédé et un filtre de rendu des couleurs conçu pour compenser une insuffisance de lumière d'éclairage provenant d'une source lumineuse dans des systèmes d'affichage. Ce filtre de rendu des couleurs présente une couleur qui est déterminée sur la base du spectre, de la sensibilité des yeux de l'observateur sur le domaine de la lumière visible et d'un seuil de gamme d'ondes prédéfini.
