Abstract

본 발명은 영상 부호화/복호화 방법 및 장치에 관한 것이다. 본 발명은 영상을 부호화하는 장치에 있어서, 현재 블록을 복수 개의 서브블록으로 분할하는 블록 분할부; 및 현재 블록의 인트라 예측 모드와 동일한 인트라 예측 모드에 근거하여, 서브블록마다 이미 부호화되고 복호화된 서브블록별 인접 픽셀 정보를 참조하여 인트라 예측 부호화를 수행하고, 현재 블록에 대한 비트스트림을 생성하는 인트라 예측 부호화부를 포함하는 것을 특징으로 하는 영상 부호화 장치를 제공한다. 본 발명에 의하면, 영상을 부호화하고 복호화하는 데 있어서, 부호화하거나 복호화하고자 하는 현재 블록을 예측할 때 그 예측의 정확도를 향상시키고, 그로 인해 만족스러운 영상 재생 품질을 제공하는 효과가 있다.
