- 이미지 데이타에 변환을 행한 후 각 프레임마다 판단함수에 의해 한계값을 가변시켜 원하는 데이타만을 선택하는 영상신호 압축전송을 위한 데이타 선택방법에 있어서, 수평과 수직 및 시간축 방향의 이미지 신호를 각각 다른 방법으로 3차원 변환하는 변환스텝과, 이미지 데이타를 취사선택하기 위한 설정된 한계값과 이미지 데이타를 비교하여 한계값보다 높은 데이타만을 선택하는 데이타 선택스텝과, 상기 데이타 선택스텝에서 선택된 데이타를 검출하는 데이타 검출스텝과, 상기 데이타 검출스탭에서 검출된 데이타량을 판단함으로써 목표한 데이타량과 비교하는 스텝과, 그리고 목표한 데이타량과 상기 비교하는 스텝에서 선택된 데이타량이 같지 않으면 다음 이미지 데이타를 받아들이기 위한 각 프레임의 한계값을 가변시키는 프레임 제어스텝을 포함하는 영상신호 압축전송을 위한 데이타 선택방법.
