Abstract

본 발명은 홈오토메이션 시스템의 카메라와 관련된 것으로서, 종래에는 이러한 카메라에 역광방지수단이 존재하지 않아 방문객등 피사체에 대한 역광작용시의 불명확한 화면을 생성하게 되어 이러한 기기 이용시의 불리한 약점으로 남아 있었다. 본 발명은 상기예의 문제점을 개선할 수 있도록 이러한 카메라를 구성하는 페이스커버를 자외선이나 단파장가시광선의 조사량에 따라 렌즈색이 자동 가변되는 조광렌즈커버로 대체하거나, 시스템 시그널 프로세싱 IC의 백라이트단을 제어하는 역광방지부를 호출스위치와 관련하여 구비시킨 홈오토메이션용 역광방지 카메라를 제공한다.The present invention relates to a camera of a home automation system, and in the related art, there is no backlight preventing means in such a camera, so that an unclear screen at the time of backlighting on a subject such as a visitor has remained a disadvantage in using such a device. The present invention is to replace the face cover constituting such a camera with a dimming lens cover that automatically changes the lens color in accordance with the irradiation amount of ultraviolet or short wavelength visible light to improve the problems of the above example, or to control the backlight stage of the system signal processing IC Provided is a backlight automation camera for home automation equipped with a backlight prevention unit associated with a call switch.
