Abstract

영상 신호의 개선된 조인트 포토그래픽 엑스퍼트 그룹(JPEG) 디콤프레션을 위한 장치 및 방법이 시사된다. 영상정보를 한번에 부분적으로 디콤프레스된 정보 부분으로 파스하는데 프로세서가 사용된다. 다음, 프로세서 또는 보조 디지털 신호 프로세서는 부분적으로 디콤프레스된 정보의 각 블록에 대한 비제로값 디멘존을 식별하고 정보의 디제로값 디멘존에 의거 부분적으로 디콤프레스된 정보의 각 블록을 디콤프레스 한다. 최종적으로 프로세서는 디콤프레스된 정보를 저장 및/또는 디스플레이 하기 위해 채용된다. 디콤프레션 단계는 파싱, 후프만 디코딩, 실행길이 디코딩, 언지그래깅, 탈양자화 및 연속 디스플레이를 위한 디콤프레스된 정보를 인터리빙하는 것을 포함한다.
