Claims (1)
- 렌즈를 통해 촬상소자에 의해 광전변환된 전기적인 신호를 디지틀 신호로 변환하기 위한 아날로그/디지틀 변환기; 상기의 디지틀 변환된 신호를 저장하기 위한 화상 메모리와; 상기의 촬상된 신호의 시간적으로 전후에 있는 프레임의 특정 영역을 검출하기 위한 영역 검출기; 상기의 촬상된 신호의 특정 영역 데이터보다 큰 영역 데이터의 엣지부분을 검출하기 위한 제1엣지 검출기; 상기의 화상 메모리에서 출력되는 데이터 신호의 엣지부분을 검출하기 위한 제2엣지 검출기; 상기의 제1엣지 검출기와 제2엣지 검출기에서 검출된 데이터를 상호 비교하여 피사체의 움직임 량과, 방향을 위한 움직임 벡터를 생성하는 영역별 움직임 벡터 생성부; 상기의 영역별 움직임 벡터 생성부에서 발생된 신호를 입력으로 하여 화상 메모리로부터의 데이터를 독출하고 화상을 보정하여 피사체의 움직임에 따라 카메라를 자동적으로 이동시켜 피사체를 촬영토록 한 제어부로 구성시켜서 됨을 특징으로 하는 피사체 자동 추적장치.
