Description

캠코더의 피사체 자동 추적장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따라 피사체를 자동으로 추적하기 위한 장치의 블럭 다이어그램,
제2도는 화면의 움직임이 피사체의 움직임인지 카메라 자체의 움직임인지를 판별하기 위한 그림이다.

Claims (1)

  1. 피사체의 셀프타이머모드 촬영시 렌즈를 통과한 광신호를 전기적인 신호로 변환하는 촬상소자와, 상기의 신호를 처리하여 비디오 테이프에 기록토록한 카메라 회로를 구비한 캠코더의 피사체자동추적장치에 있어서, 상기 렌즈의 망원 및 광각위치를 검출하여 디지틀신호로 변환하기 위한 줌위치검출기, 상기 카메라 회로에서 처리된 영상휘도신호를 디지틀신호로 변환하는 아날로그/디지틀 변환기, 상기의 디지틀신호를 제1필드와 제2필드별로 저장하기 위한 2개의 필드메모리, 상기의 필드메모리에 각각 저장된 전화면과 후화면을 비교하여 화면움직임의 방향과 량을 움직임 벡터로서 검출하기 위한 움직임 검출기, 상기의 화면움직임이 카메라 자체의 움직임인지 피사체의 움직임인지를 판단하여 피사체가 움직이는 경우 피사체의 움직임 방향과 량에 대한 정보 신호를 발생하여, 상기의 줌위치에 대한 정보신호를 입력받은 제어장치와, 상기의 제어장치로부터의 정보 신호를 입력하여 카메라를 회전시키는 방향과 량 및 회전속도 신호를 발생시켜 카메라가 피사체를 자동으로 추적토록한 모터제어기로 구성시켜서 됨을 특징으로 하는 캠코더의 피사체자동 추적장치.
