Abstract

Selon l'invention, un dispositif de traitement vidéo est équipé d'un convertisseur de sous-champs (2), qui convertit des images d'entrée en données de luminescence pour chaque sous-champ, un détecteur de données de cinéma (5), qui détecte que des images d'entrée sont des images de cinéma dans lesquelles les mêmes images vidéo sont délivrées consécutivement dans au moins deux périodes de champ, un détecteur de vecteurs de mouvement (3), qui détecte des vecteurs de mouvement en utilisant deux images d'entrée chronologiquement consécutives, et un régénérateur de sous-champs (4), qui, quand il est détecté que des images d'entrée sont des images de cinéma, prend au moins deux images vidéo d'au moins deux périodes de champ comme une image vidéo à traiter, et réarrange spatialement les données de luminescence pour chaque sous-champ de l'image vidéo à traiter en fonction du vecteur de mouvement qui a été détecté, et génère ainsi des données de luminescence réarrangées pour chaque sous-champ de l'image vidéo à traiter.
