Abstract

캠코더 및 감시용 카메라를 공개한다. 그 캠코더는 피사체의 입사광에 따라 촬상신호를 발생하는 전하결합디바이스와, 픽셀 단위의 불연속적인 그 촬상신호를 샘플링을 수행하여 연속적인 신호로 변환하며, 이득 조절을 하는 샘플링 및 이득 조절부와, 아날로그-디지탈 변환기와, 적외선을 차단하기 위한 적외선 차단용 필터와, 그 필터를 이동시키기 위한 이동수단과, 상기 디지탈 변환된 신호의 신호량에 따라 상기 이동수단을 제어하여 상기 전하결합디바이스에 입사되는 적외선의 차단여부를 결정하는 마이콤을 구비하는 것을 특징으로 한다. 본 발명에 의하면, 그 캠코더는 라이트 없이도 야간 촬영이 가능하다는 잇점이 있다.Camcorders and surveillance cameras are released. The camcorder comprises a charge coupled device for generating an imaging signal in response to incident light from a subject, a sampling and conversion of the discrete imaging signal in a pixel unit into a continuous signal, sampling and gain adjusting unit for gain adjustment, and an analog A digital converter, an infrared cut-off filter for blocking infrared rays, a moving means for moving the filter, and an infrared ray incident on the charge coupled device by controlling the moving means in accordance with the signal amount of the digitally converted signal Characterized in that it comprises a microcomputer to determine the blocking of. According to the present invention, the camcorder has the advantage that it is possible to photograph at night without a light.
