Abstract

Selon certains modes de réalisation, la présente invention concerne un procédé et un appareil d'affichage d'image, le procédé consistant à : acquérir un signal vidéo à traiter, le signal vidéo à traiter comprenant des données d'image à traiter et des données de suppression correspondant à celles-ci ; lorsque les données d'image à traiter ne correspondent pas à la zone d'affichage, acquérir la position des bords entre les données d'image à traiter et les données de suppression par rapport à la zone d'affichage ; sur la base de la position, régler les données d'image à traiter pour correspondre à la zone d'affichage ; et afficher les données d'image réglées dans la zone d'affichage. Les données d'image réglées correspondent à la zone d'affichage, améliorant ainsi les effets d'affichage d'image.
