Abstract

본 발명은 동영상 부호화/복호화 장치, 이를 위한 적응적 디블록킹 필터링 장치와 필터링 방법, 및 기록 매체에 관한 것으로, 본 발명의 실시예에 따른 디블록킹 필터링 장치는, 현재 블록의 서브 블록간의 경계의 세기를 결정하는 경계 세기 결정부; 상기 경계를 기준으로 기 설정된 복수의 방향 중 하나씩 순차적으로 선택하는 방향 선택부; 상기 선택된 방향에 근거하여 필터링할 화소들을 선택하는 화소 선택부; 상기 선택된 화소들간의 화소값의 관계에 따라 상기 선택된 방향에 대한 필터링 여부를 결정하는 필터링 결정부; 상기 결정된 필터링 여부에 따라 상기 선택된 방향의 상기 선택된 화소들에 대해 필터링을 수행하는 필터링부를 포함하여 구성되어, 수직 수평 방향 뿐만 아니라 그 밖의 다수의 방향에 대해서도 화소 단위로 디블록킹 필터를 적용하여, 다수의 사선 방향에 대한 에지로 인하여 생기는 사선 방향의 불연속 성에 의한 블록 왜곡 현상을 효과적으로 제거한다.
