Abstract:
(EN) The present invention relates to a method and an apparatus for encoding/decoding a color image. The apparatus for encoding an image: encodes a luminance component block for a current block of the image, selects one among plural color formats to encode a chrominance component block for the current block of the image according to the selected color format, and generates and outputs a bit stream including the information on the encoded luminance component block, the encoded chrominance component block, and the selected color format. The invention enables an improvement in compression performance by encoding and decoding one image which constitutes a video in various color formats.
(FR) La présente invention se rapporte à un procédé et à un appareil pour le codage/décodage d'une image en couleur. L'appareil pour le codage d'une image : code un bloc de composante de luminance pour un bloc courant de l'image; sélectionne un format parmi plusieurs formats de couleur afin de coder un bloc de composante de chrominance pour le bloc courant de l'image, conformément au format de couleur sélectionné; et génère, puis émet en sortie, un flux de bits contenant les informations concernant le bloc de composante de luminance codé, le bloc de composante de chrominance codé et le format de couleur sélectionné. L'invention permet une amélioration de la performance de compression en permettant le codage et le décodage d'une image constituant une vidéo en divers formats de couleur.
(KO) 본 발명은 컬러 영상 부호화/복호화 방법 및 장치에 관한 것이다. 본 발명은 영상을 부호화하는 장치가 영상의 현재 블록에 대한 휘도 성분 블록을 부호화하고, 복수 개의 컬러 포맷 중 하나의 컬러 포맷을 선택하여, 선택된 컬러 포맷에 따라 영상의 현재 블록에 대한 색차 성분 블록을 부호화하며, 부호화된 휘도 성분 블록, 부호화된 색차 성분 블록 및 선택된 컬러 포맷에 대한 정보를 포함하는 비트스트림을 생성하여 출력하는 것을 특징으로 한다. 본 발명에 의하면, 동영상을 구성하는 하나의 영상을 다양한 컬러 포맷으로 부호화하고 복호화할 수 있도록 함으로써, 압축 성능을 향상시킬 수 있다.
