Abstract
(EN)
An image decoding method according to the present invention may comprise the steps of: determining whether a combined prediction mode is applied to a current block; when the combined prediction mode is applied to the current block, obtaining first and second prediction blocks with respect to the current block; and, on the basis of a calculation of a weighted sum of the first and second prediction blocks, obtaining a third prediction block with respect to the current block.
(FR)
L'invention concerne un procédé de décodage d'image qui peut comprendre les étapes consistant à : déterminer si un mode de prédiction combiné est appliqué à un bloc actuel ; lorsque le mode de prédiction combiné est appliqué au bloc actuel, obtenir des premier et deuxième blocs de prédiction par rapport au bloc actuel ; et, sur la base d'un calcul d'une somme pondérée des premier et deuxième blocs de prédiction, obtenir un troisième bloc de prédiction par rapport au bloc actuel.
