Title (EN) METHOD FOR RENDERING COLOR IMAGES
(FR) PROCÉDÉ PERMETTANT DE RESTITUER DES IMAGES EN COULEURS
Abstract:
(EN) A system for rendering color images on an electro-optic display when the electro-optic display has a color gamut with a limited palette of primary colors, and/or the gamut is poorly structured (i.e., not a spheroid or obloid). The system uses an iterative process to identify the best color for a given pixel from a palette that is modified to diffuse the color error over the entire electro-optic display. The system additionally accounts for variations in color that are caused by cross-talk between nearby pixels.
(FR) L'invention concerne un système permettant de restituer des images en couleurs sur un dispositif d'affichage électro-optique lorsque l'affichage électro-optique possède une gamme de couleurs ayant une palette limitée de couleurs primaires et/ou lorsque la gamme est faiblement structurée (c'est-à-dire qu'elle n'est ni sphéroïde ni oblongue). Le système utilise un processus itératif permettant d'identifier la meilleure couleur pour un pixel donné à partir d'une palette qui est modifiée afin de diffuser l'erreur de couleur sur l'ensemble de l'affichage électro-optique. Le système tient en outre compte des variations de couleur provoquées par une diaphonie entre pixels voisins.
