- 영상처리 시스템의 영상정보 압축 및 복원 방법에 있어서, 입력되는 디지탈 데이타 값을 계승값으로 변환시키는 계승코드 변환루틴(L1)과, 상기 계승코드 변환루틴(L1)에서 출력되는 계승코드(Q1~Qn)를 크기비교가 가능한 데이타로 변환하는 큐빅 코드 변환루틴(L2)과, 상기 큐빅 코드 변환루틴(L2)에서 출력되는 데이타를 크기비교하여 인터널 비트와 어덥티브비트로 출력하는 FASCM 변환 루틴(L3)의 순으로 이루어진 데이타 압축과정과 ; 상기 데이타 압축과정에 의하여 압축된 데이타를 크기순서대로 정렬하는 역 FASCM 변환루틴(L4)과, 상기 역 FASCM 변환루틴(L4)에 의하여 크기순서대로 정렬된 데이타로부터 계승코드(Q1~Qn)를 추출하기 위한 역 큐빅 코드 변환루틴(L5)과, 상기 역 큐빅 코드 변환루틴(L5)에 의한 계승코드(Q1~Qn)를 디지탈 데이타로 복원시키는 역계승코드 변환루틴(L6)의 순으로 이루어지는 데이타 복원과정으로 이루어지는 영상처리 시스템의 데이타 변복조방법.
- 제1항에 있어서, 계승코드 변환루틴(L1)은 다음식을 만족하는 스텝으로 이루어진 영상처리 시스템의 데이타 변복조방법, 데이타(D1~DN)=Qn×N!+Qn-1×(N-1)!…Q2×2!+Q1×1! 여기서 Q1~Qn은 계승코드이다.
- 제1항에 있어서, 큐빅 변환루틴(L2)은, A=N-(Qn-1)을 만족하면 데이타를 N번째 계승코드의 데이타로 치환하는 스텝(S5~S10)과, A=N+1을 만족하면 큐빅 변환하지 않는 스텝(S11~S15)으로 이루어지는 영상처리 시스템의 데이타 변복조방법.
- 제1항에 있어서, FASCM 변환루틴(L3)은, 바로 이전의 데이타부터 크기를 비교하는 판별스텝(S16~S19)과, 상기 판별스텝(S19)에 의하여 바로 이전의 데이타보다 크기가 크면 "로직 1"로, 상기 판별 스텝(S19)에 의하여 바로이전의 데이타의 크기가 작으면, "로직 0"으로 되는 인터널비트를 추출하는 스텝(S20~S23)과, 상기 스텝(S23)에 의하여 추출된 바로 이전의 인터널 비트가 로직 1이면, 지금까지의 데이타중 가장 큰것부터 크기비교하고, 바로 이전의 인터널 비트가 로직 0이면 데이타의 하측 중심부터 크기비교하여 인텁티브 비트를 추출하는 스텝(S24~S32)으로 이루어지는 영상처리 시스템의 데이타 변복조방법.
- 제1항에 있어서, 역 FASCM 변환루틴(L4)은, 저장된 인터널비트와 어덥티브비트에 의하여 데이타의 크기 순서대로 정렬하여 계승치(D1~DN)를 추출하는 스텝(S100~S103)으로 이루어진 영상처리 시스템의 데이타 변복조방법.
- 제1항에 있어서, 역큐빅 코드 변환루틴(L5)은, 일련의 정수(1~N)로 디폴트데이타(d1~dN)가 설정되는 스텝(S104~S107)과, 참조 데이타((R(Di))=di이면, 계승코드(Qi)는 0이고, 설정데이타(R(Di))≠di이면, 계승코드(Qi)가 (Qi)=N+1-Di으로 되며, 상기 참조데이타(R(Di))를 기준데이타(Ri)와 참조데이타의 R(di)에 저장하는 스텝(S108~S115)으로 되는 영상처리 시스템의 데이타 변복조방법.
