Title (EN) METHOD AND DEVICE FOR PROCESSING VIDEO SIGNAL
(FR) PROCÉDÉ ET DISPOSITIF DE TRAITEMENT DE SIGNAL VIDÉO
(KO) 비디오 신호 처리 방법 및 장치
Abstract:
(EN) An image decoding method according to the present invention may comprise the steps of: determining an intra prediction mode of a current block; when the intra prediction mode of the current block is a DC mode, determining a DC value on the basis of at least one among left reference samples and top reference samples of the current block; and inducing a prediction sample of the current block on the basis of the DC value.
(FR) La présente invention concerne un procédé de décodage d'image pouvant comprendre les étapes consistant : à déterminer un mode de prédiction intra d'un bloc de courant; lorsque le mode de prédiction intra du bloc de courant est un mode de courant continu, à déterminer une valeur de courant continu sur la base d'au moins un échantillon parmi des échantillons de référence gauche et des échantillons de référence supérieurs du bloc de courant; et à induire un échantillon de prédiction du bloc de courant sur la base de la valeur de courant continu.
(KO) 본 발명에 따른 영상 복호화 방법은, 현재 블록의 인트라 예측 모드를 결정하는 단계, 상기 현재 블록의 인트라 예측 모드가 DC 모드인 경우, 상기 현재 블록의 좌측 참조 샘플들 또는 상단 참조 샘플들 중 적어도 하나를 기초로 DC값을 결정하는 단계, 및 상기 DC값을 기초로 상기 현재 블록의 예측 샘플을 유도하는 단계를 포함할 수 있다.
