CA 2583156

Briefly, in accordance with a preferred embodiment of the present principles, simulation of a block of film grain for addition to a block of an image occurs by first establishing at least one image parameter in accordance with at least one attribute of the block. Thereafter, a block of film grain is established in accordance with the image parameter. Deblocking filtering can be applied to the film grain block.

Selon un mode de mise en oeuvre préféré de cette invention, la simulation d'un bloc de grain d'émulsion destiné à être ajouté à un bloc d'une image se produit lorsqu'on établit d'abord au moins un paramètre d'image conformément au moins à un attribut du bloc. On établit ainsi un bloc de grain d'émulsion conformément au paramètre de l'image. On peut appliquer un filtre de déblocage sur le bloc de grain d'émulsion.
