Claims (1)

  1. 움직임 보상과 프레임간 부호화를 조합시킨 대역 압축 장치에 있어서, 입력 화상 데이타를 직교 변환하여, 제1의 직교 변환 출력을 형성하여, 프레임 메모리의 출력에 대해서도, 상기 직교 변환과 같은 직교 변환을 행함과 함께, 지연을 부여하므로서, 현 프레임과 어긋난 복수의 위치에 각각 대응하는 제2의 직교 변환 출력을 형성하여, 상기 제1의 직교 변환 출력과 상기한 복수의 위치에 대응하는 제2의 직교 변환 출력과의 차를 각각 연산하여, 상기한차에 의거해서, 데이타 압축 효과의 가장 높은 어긋난량의 데이타에 대한 출력차를 부호하 출력으로서 이용하도록 한 것을 특징으로 하는 대역 압축 장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
