Abstract

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.
