Abstract

L'IMAGE EST DIVISEE EN TROIS PLANS DE COULEUR COMPOSANTE, DIVISES EN BLOCS ET CODES PAR LES PREMIER, SECOND ET TROISIEME MOYENS DE CODAGE. LE PREMIER DE CES MOYENS AFFECTE A CHAQUE BLOC DES CODES REPRESENTATIFS DE NIVEAUX DE GRIS ET UN CODE DE RESOLUTION INDIQUANT LA DISTRIBUTION DE CES CODES. QUAND LE NIVEAU DE GRIS DU BLOC VARIE PEU, ON PEUT ADOPTER UN CODE DE NIVEAU DE GRIS MOYEN ET SUPPRIMER LE CODE DE RESOLUTION. LES SECOND ET TROISIEME MOYENS DE CODAGE PEUVENT ETRE IDENTIQUES AU PREMIER. LE CODE DE RESOLUTION ETABLI PAR LE PREMIER CODEUR PEUT SERVIR POUR LES BLOCS CORRESPONDANTS DANS LES AUTRES CODEURS. DANS LE PREMIER CODEUR, LA GRANDEUR DES BLOCS PEUT ETRE MODIFIEE LOCALEMENT SELON L'ETAT DU PLAN DE COULEUR ET CETTE MODIFICATION PEUT SERVIR AUSSI DANS LES DEUX AUTRES CODEURS. APPLICATION AU STOCKAGE ET A L'AFFICHAGE SUR DEMANDE D'IMAGES EN COULEURS.
