Abstract: front page image
(EN) An image encoding/decoding method and device for performing an intra prediction are provided. The image decoding method of the present invention comprises the steps of: inducing an intra prediction mode for a current block; determining whether a left side or an upper end boundary of the current block is a boundary of a predetermined image area; configuring a reference sample by using at least one reconstructed sample included in at least one reconstructed sample line adjacent to the current block, on the basis of the determination result; and performing intra prediction with respect to the current block on the basis of the intra prediction mode and the reference sample.
(FR) L'invention concerne un procédé et un dispositif de codage et de décodage d'image destinés à effectuer une intraprédiction. Le procédé de décodage d'image de la présente invention comprend les étapes consistant à : entraîner un mode d'intraprédiction pour un bloc actuel ; déterminer si un côté gauche ou une limite d'extrémité supérieure du bloc actuel est une limite d'une zone d'image prédéterminée ; configurer un échantillon de référence à l'aide d'au moins un échantillon reconstruit compris dans au moins une ligne d'échantillon reconstruite adjacente au bloc actuel, sur la base du résultat de détermination ; et réaliser une intraprédiction par rapport au bloc actuel sur la base du mode d'intraprédiction et de l'échantillon de référence.
