Abstract

Un appareil et des procédés mettant en uvre une ou plusieurs techniques visant à réduire le temps nécessaire à laffichage dimages à haute résolution sur un écran à grande plage dynamique présentant une couche source lumineuse et une couche daffichage. Selon une technique, la résolution de limage est réduite, un motif de luminance effective est déterminé pour la résolution dimage réduite et la résolution du motif de luminance effective est ensuite augmentée jusquà la résolution de la couche daffichage. Selon une autre technique, la fonction détalement des points de la couche source lumineuse est décomposée en une pluralité de composantes et un motif de luminance effective est déterminé pour chaque composante. Les motifs de luminance effective sont ensuite combinés pour produire un motif de luminance effective total. Des techniques de réduction de temps daffichage dimage supplémentaires sont également décrites.
