Abstract
(EN)
The present invention provides a compensation table compression method. In the compensation table compression method, by means of a visual lossless compression compensation table, the quality loss of an original compensation table is not sensed by a human eye, and the compression efficiency is greatly increased. Compared with an existing compensation table compression algorithm, the present invention can obtain an optimal quantization step size without iteration, reduces the occupation of memory space, saves hardware resources of a system, may reduce costs, and reduces the time consumed for transmitting and burning data.

La présente invention concerne un procédé de compression de table de compensation. Dans le procédé de compression de table de compensation, au moyen d'une table de compensation de compression sans perte visuelle, la perte de qualité d'une table de compensation d'origine n'est pas détectée par un oeil humain, et l'efficacité de compression est fortement augmentée. Par comparaison avec un algorithme de compression de table de compensation existant, la présente invention peut obtenir une taille de pas de quantification optimale sans itération, réduit l'occupation de l'espace mémoire, économise les ressources matérielles d'un système, peut réduire les coûts, et réduit le temps consommé pour la transmission et le rodage des données.
