Title (EN) METHOD AND APPARATUS FOR ENCODING/DECODING INTRA PREDICTION MODE
(FR) PROCÉDÉ ET APPAREIL DE CODAGE/DÉCODAGE EN MODE DE PRÉDICTION INTRA
(KO) 인트라 예측 모드 부호화/복호화 방법 및 장치
Abstract: front page image
(EN)An image decoding method, according to the present invention, includes the steps of: deriving an MPM candidate mode from neighboring blocks adjacent to a target block to be decoded; generating an MPM list using the MPM candidate mode derived from the neighboring blocks; and deriving an intra prediction mode for the target block to be decoded using the generated MPM list. According to the present invention, image compression efficiency can be improved.
(FR)Selon la présente invention, un procédé de décodage d'image comprend les étapes consistant à: dériver un mode MPM candidat de blocs voisins adjacents à un bloc cible à décoder; générer une liste MPM en utilisant le mode MPM candidat dérivé des blocs voisins; et dériver un mode de prédiction intra pour le bloc cible à décoder en utilisant la liste MPM générée. Le procédé de l'invention permet d'améliorer l'efficacité de compression d'image.
(KO)본 발명에 따른 영상 복호화 방법은 복호화 대상 블록에 인접한 주변 블록으로부터 MPM 후보 모드를 도출하는 단계, 주변 블록으로부터 도출된 MPM 후보 모드를 이용하여 MPM 리스트를 생성하는 단계 및 생성된 MPM 리스트를 이용하여 복호화 대상 블록의 인트라 예측 모드를 도출하는 단계를 포함한다. 본 발명에 의하면, 영상 압축 효율이 향상될 수 있다.
