Patent

CA 2574739

The invention concerns a method comprising a coding step consisting in replacing the original values of the file with coding values of reduced brightness, a common coding value being attributed to a group of original values, a step of restitution consisting in setting correspondence values between the coding value and the restored value, selected from one of the values of the corresponding group, an insertion step consisting in modifying the successive redundant restored values so as to produce shades and a step which consists in reading the values resulting from the insertion step.

Le procédé selon l'invention comprend une étape de codage comportant le remplacement des valeurs d'origines du fichier par des valeurs de codage de luminosité réduite, une même valeur de codage étant attribuée à un groupe de valeurs d'origine, une étape de restitution comportant l'établissement des valeurs de correspondances entre la valeur de codage et une valeur restituée, choisie parmi l'une des valeurs du groupe correspondant, une étape d'adjonction consistant à modifier les valeurs restituées redondantes successives de manière à faire apparaître des nuances et une étape de lecture des valeurs issues de l'étape d'adjonction.
