Abstract
Dans la présente invention, un dispositif de codage vidéo est apte à sélectionner, parmi une pluralité d'espaces colorimétriques, un espace colorimétrique d'un signal d'erreur de prédiction dans des unités de bloc codé, et comprend ce qui suit : une partie de calcul de décalage de quantification de chrominance adaptatif pour calculer un décalage de quantification de chaque espace colorimétrique ; et une partie de quantification inverse qui exécute une quantification inverse sur une image de coefficient de quantification au moyen du décalage de quantification de chrominance de chaque espace colorimétrique.
