The present invention relates to a vehicle lamp brightness control device using a camera, wherein front illumination is detected by using a distance detection camera for an advanced emergency braking system (AEBS) basically provided in a vehicle without using a separate detection sensor, and the brightness of a lamp is automatically adjusted using the detection result. The vehicle lamp brightness control device using a camera comprises: a lamp switch for selecting a lamp to be turned on; an AEBS for detecting front illumination; an electronic control device for calculating brightness by analyzing a photographed image from the AEBS, and generating a head lamp brightness control signal according to the illumination based on the calculated brightness; and a voltage control module for extracting a head lamp brightness control value corresponding to the head lamp brightness control signal generated in the electronic control device from an internal memory when a head lamp switch of the lamp switch is on, and automatically adjusting the brightness of a head lamp by outputting the extracted head lamp brightness control value to the head lamp.

    별도의 감지 센서를 이용하지 않고 차량에 기본적으로 구비된 자동긴급제동장치(Advanced Emergency Braking System, AEBS)를 위한 거리 감지용 카메라를 이용하여 전방 조도를 감지하고, 이를 이용하여 램프의 밝기를 자동으로 조절할 수 있도록 한 카메라를 이용한 차량 램프 밝기제어장치에 관한 것으로서, 점등할 램프를 선택하기 위한 램프 스위치, 전방 조도 감지를 감지하는 자동긴급제동장치(AEBS), 자동긴급제동장치로부터 촬영한 영상을 분석하여 밝기를 산출하고, 산출한 밝기를 기초로 조도에 따른 헤드램프 밝기 조정 제어신호를 발생하는 전자제어장치 및 램프 스위치의 헤드램프 스위치가 온 상태이면 상기 전자제어장치에서 발생한 헤드램프 밝기 조정 제어신호에 대응하는 헤드램프의 밝기 조정 값을 내부 메모리로부터 추출하고, 추출한 헤드램프 밝기 조정 값을 헤드램프에 출력하여 헤드램프의 밝기를 자동으로 조정하는 전압조정모듈을 포함하여, 카메라를 이용한 차량 램프 밝기제어장치를 구현한다.
