Title (EN) COLOR LOOK UP TABLE COMPRESSION
(FR) COMPRESSION DE TABLE DE CONSULTATION DE COULEUR
Abstract:
(EN) A memory device includes a compressed color table and corrective information. The compressed color table includes a first set of nodes of the color table compressed with a lossy compression at a selected compression ratio. The first set of nodes include a color difference within an error threshold at the selected compression ratio. Corrective information is included for a second set of nodes of the color table. The second set of nodes have a color difference outside the error threshold.
(FR) L'invention concerne un dispositif de mémoire qui comprend une table de couleurs comprimée et des informations correctrices. La table de couleurs comprimée comprend un premier ensemble de nœuds de la table de couleurs comprimée comportant une compression avec perte à un taux de compression sélectionné. Le premier ensemble de nœuds comprend une différence de couleur dans un seuil d'erreur au taux de compression sélectionné. Des informations correctrices sont comprises pour un second ensemble de nœuds de la table de couleurs. Le second ensemble de nœuds présente une différence de couleur en dehors du seuil d'erreur.
