Abstract
Description
Claims (4)
- 밤이나 조명이 없는 곳에서 적외선 조명을 행하는 적외선 조명기와, 상기 조명기의 조명에 의해 외부의 화상정보를 입력하는 렌즈와, 상기 렌즈에 의해 입력된 화상정보를 필터링하는 OLPF와, 외부 광원으로부터 입력되는 광을 축적하였다가 상기 렌즈에서 수집된 화상정보와 함께 수직동기신호에 맞추어 외부로 출력하는 CCD와, 상기 CCD에서 보내진 아날로그 신호를 디지털 신호로 변환하는 DSP 칩으로 구성된 CCD 카메라에 있어서,상기 조명기, 렌즈, OLPF, CCD 및 DSP 칩이 일체로 구성되고,상기 OLPF는 620~820nm의 적외선 대역이 필터링되며,상기 OLPF는 가시광선 영역에서는 95% 이상의 투과율을 나타내고, 적외선 대역에서는 50% 이하의 투과율을 나타내는 것을 특징으로 하는 일체형 CCD카메라.
- 제 1항에 있어서,상기 적외선 조명기는 내부의 광센서에 의해 외부의 조도가 1룩스 이하일 경우 온으로 자동전환되며, 상기 DSP칩은 내부의 광센서에 의해 조도가 1룩스 이하인 경우 컬러모드에서 흑백모드로 자동전환시키는 것을 특징으로 하는 일체형 CCD카메라.
