Title (EN) METHOD FOR SCANNING TRANSFORM COEFFICIENT AND DEVICE THEREFOR
(FR) PROCÉDÉ DE NUMÉRISATION DE COEFFICIENT DE TRANSFORMÉE ET DISPOSITIF ASSOCIÉ
(KO) 변환 계수 스캔 방법 및 그 장치
Abstract: front page image
(EN)The method for scanning a transform coefficient of the present invention comprises the steps of: determining a reference transform block for a block to be decoded; deriving a scanning map of the block to be decoded using scanning information of the reference transform block; and executing a reverse-scan on the transform coefficient of the block to be decoded using the derived scanning map. The present invention enhances image encoding/decoding efficiency.
(FR)L'invention concerne un procédé permettant de numériser un coefficient de transformée consistant à : déterminer un bloc de transformée de référence pour un bloc à décoder ; dériver une carte de numérisation du bloc à décoder au moyen des informations de numérisation du bloc de transformée de référence ; et exécuter une numérisation inverse sur le coefficient de transformée du bloc à décoder au moyen de la carte de numérisation dérivée. L'invention améliore l'efficacité du codage/décodage d'images.
(KO)본 발명에 따른 변환 계수 스캔 방법은, 복호화 대상 블록에 대한 참조 변환 블록을 결정하는 단계, 참조 변환 블록의 스캐닝 정보를 이용하여 복호화 대상 블록의 스캐닝 맵을 도출하는 단계 및 도출된 스캐닝 맵을 이용하여 복호화 대상 블록의 변환 계수에 대한 역 스캐닝을 수행하는 단계를 포함한다. 본 발명에 의하면 영상 부호화/복호화 효율이 향상될 수 있다.
