Abstract
(EN)
The present invention relates to an image processing device and method that are capable of suppressing a reduction in coding efficiency. The image processing device comprises: a prediction vector generation unit that, when encoding a current parallax vector for a current block to be used in prediction which uses the correlation of parallax directions, uses a reference parallax vector, which is referred to when generating prediction motion vectors, to generate a prediction vector for the current parallax vector; and a difference vector generation unit that generates a difference vector between the current parallax vector and the prediction vector generated by the prediction vector generation unit. This disclosure can be applied to image processing devices.

La présente invention concerne un dispositif et un procédé de traitement d'image qui sont aptes à supprimer une réduction du rendement de codage. Le dispositif de traitement d'image comprend : une unité de génération de vecteur de prédiction qui, lors du codage d'un vecteur de parallaxe courant pour un bloc courant à utiliser en prédiction qui utilise la corrélation de directions de parallaxe, utilise un vecteur de parallaxe de référence, auquel il est fait référence lors de la génération de vecteurs de mouvement de prédiction, afin de générer un vecteur de prédiction pour le vecteur de parallaxe courant ; et une unité de génération de vecteur de différence qui génère un vecteur de différence entre le vecteur de parallaxe courant et le vecteur de prédiction généré par l'unité de génération de vecteur de prédiction. Cette invention peut être appliquée à des dispositifs de traitement d'image.
