Title
(EN) TECHNIQUES FOR DETERMINING EFFECTIVE COLOR SPACE OF A DISPLAY
(FR) TECHNIQUES POUR DÉTERMINER UN ESPACE DE COULEUR EFFECTIF D'UN DISPOSITIF D'AFFICHAGE
Abstract
(EN)
A method and device for determining an effective color space of a display perform the following steps. A two-dimensional parametric surface that intersects a color volume defined for the display can be defined for at least one color volume vertex (202). A flat bitmap to which the two-dimensional parametric surface is mapped (204) can be displayed (208), on the display, for the at least one color volume vertex. A selection of a point on the flat bitmap that corresponds to a perceived maximum color can be received for the at least one color volume vertex (210). The effective color space of the display can be determined based at least in part on the perceived maximum color selected for the at least one color volume vertex (212).

La présente invention concerne un procédé et un dispositif pour déterminer un espace de couleur effectif d'un dispositif d'affichage réalisant les étapes suivantes. Une surface paramétrique bidimensionnelle qui coupe un volume de couleur défini pour le dispositif d'affichage peut être définie pour au moins un sommet de volume de couleur (202). Une matrice de bits plate à laquelle la surface paramétrique bidimensionnelle est mappée (204) peut être affichée (208), sur le dispositif d'affichage, pour le ou les sommets de volume de couleur. Une sélection d'un point sur la matrice de bits plate qui correspond à une couleur maximale perçue peut être reçue pour le ou les sommets de volume de couleur (210). L'espace de couleur effectif du dispositif d'affichage peut être déterminé sur la base, au moins en partie, de la couleur maximale perçue sélectionnée pour le ou les sommets de volume de couleur (212).
