Abstract

Des modes de réalisation de la demande concernent une méthode et un appareil de prédiction d'image. La méthode de prédiction d'image comprend : déterminer si un mode de fusion est utilisé pour un bloc d'image actuel; si le mode de fusion est utilisé pour le bloc d'image actuel, déterminer si un mode de fusion de niveau 1 est disponible pour le bloc d'image actuel; si un premier mode de fusion n'est pas disponible et qu'un élément de syntaxe de couche élevée correspondant au premier mode de fusion indique que le premier mode de fusion est interdit d'utilisation, déterminer directement un deuxième mode de fusion comme mode de fusion cible applicable au bloc d'image actuel, le premier et le deuxième mode de fusion appartenant à un mode de fusion de niveau 2; et prédire le bloc d'image actuel en fonction du mode de fusion cible. Dans certains modes de réalisation de la demande, la redondance produite dans un procédé de détermination du mode de fusion peut être réduite autant que possible.
