Abstract

복호 영상 버퍼 압축장치 및 그 압축방법이 개시된다. 본 발명의 실시예에 따른 복호 영상 버퍼 압축장치는, 영상의 국지적 화소값 분포에 기초하여 복호 영상 버퍼에 대한 압축 수행의 블록 크기를 조절하는 적응적 블록크기 결정부; 적응적 블록크기 결정부에 의해 결정된 블록 크기를 수행단위로 하여 복호 영상의 비트 깊이를 감소시키는 적응적 스케일링(Adaptive scaling)을 수행하는 복호 영상 버퍼 압축부; 및 복호 영상 버퍼 압축부에서 발생한 복호 영상의 최소 화소값과 적응적 시프트(Shift value) 값을 포함하는 부가정보를 저장하는 부가정보 저장부를 포함하는 것을 특징으로 한다.
