Title
(EN) COLOR ACCURACY ACROSS A COMPUTER NETWORK
(FR) PRECISION D'AFFICHAGE COULEUR DANS UN RESEAU INFORMATIQUE
Abstract
(EN)
Improved color image display accuracy can be achieved across a computer network by obtaining information characterizing the color response of display devices associated with a client residing on the computer network, and using the information to modify color images delivered to the client. The modifications can be designed to compensate for the color response of the individual display device associated with the client. The display device may take the form of a cathode ray tube monitor, flat panel display, or similar color image display device. The information can be obtained, for example, by guiding the client through a color profiling process that profiles the color response of the display device. For example, such guidance may take the form of a series of instructional web pages that are delivered to the client. The web pages can be made interactive to enable collection of color characterization data from the client. The color characterization data can be used to estimate a variety of information concerning display device characteristics such as gamma, black point, gray balance, and the like.

Selon cette invention, on obtient une plus grande précision d'affichage d'une image couleur dans un réseau informatique au moyen d'informations caractérisant le réponse couleur des dispositifs d'affichage associés à un client résidant sur le réseau informatique et en utilisant ces informations pour modifier l'image couleur envoyée au client. Les modifications peuvent être adaptées pour compenser la réponse couleur du dispositif d'affichage individuel associé au client. Ce dispositif d'affichage peut avoir la forme d'un moniteur de tube cathodique, d'un panneau plat ou autre dispositif d'affichage similaire d'image couleur. On peut, par exemple, obtenir ces informations en guidant le client dans un processus de profilage qui profile la réponse couleur du dispositif d'affichage. Le guidage peut s'effectuer sous la forme d'une série de pages web d'instructions qui sont envoyées au client. Les pages web peuvent être interactives pour permettre la collecte de données de caractérisation des couleurs provenant du client. Ces données peuvent être utilisées pour évaluer différentes informations concernant les caractéristiques du dispositif d'affichage telles que facteur de contraste, point noir, équilibre des gris et analogue.
