Abstract

본 발명에 따른 인트라 복호화 장치는 수신된 비트 스트림으로부터 양자화된 잔차계수, 인트라 예측 정보 및 예측 유닛의 크기 정보를 복원하고, 상기 인트라 예측 정보 및 현재 예측 유닛의 크기 정보에 기초하여 현재 예측 유닛의 인트라 예측 모드를 복원하고, 예측 유닛의 이용 가능하지 않은 참조 화소를 생성하여 상기 인트라 예측 모드에 기초하여 참조화소를 적응적으로 필터링한다. 또한, 상기 인트라 예측 모드에 대응하는 참조픽셀들을 이용하여 예측블록을 생성하고 적응적으로 필터링하여 예측블록을 생성한다. 그리고, 상기 예측블록과 복원된 잔차블록을 이용하여 복원영상을 생성한다. 따라서, 원본 영상에 가까운 예측 블록을 복원할 수 있게 되어, 영상 압축률을 높일 수 있다.
