Abstract

본 발명은 카메라로 야간 프레쉬 촬영시 피사체의 구도를 설정하기 위한 보조램프 구동장치에 관한 것으로서, 종래의 콤팩트 카메라에는 본 발명과 같은 장치가 구비되어 있지 않아, 야간에 프레쉬를 이용하여 촬영을 할 경우 피사체가 전혀 보이지 않아도 피사체의 상을 대략적으로 화인더의 구도에 맞춘다음 촬영에 임하므로써 구도가 잘못 맞추어졌을 경우 피사체가 잘린 상태에서 촬영될 수 있을 뿐만 아니라 피사체의 구도를 맞춘다 하더라도 시간이 많이 소요되는 등의 문제점이 있었다.The present invention relates to an auxiliary lamp driving device for setting the composition of a subject during night-time fresh shooting with a camera, and the conventional compact camera is not equipped with the same device as the present invention, and when taking a picture using fresh at night. Even if the subject is not visible at all, the image of the subject is roughly matched to the framer's composition, and then photographed. There was a problem.

따라서, 본 발명에서는 기존의 콤팩트 카메라에 피사체 확인 수단인 보조램프(L1)등을 부가시켜 주변밝기 검출수단을 통해 검출한 주변의 밝기가 피사체의 구도를 잡을 수 있을 정도로 어두어 주변밝기 검출수단의 출력전압이 소정전압 이하가 된 상태에서 자동포커스를 구동시키는 셔터 릴리즈 1단 스위치(S1)가 '온'이되면, 상기 피사체 확인수단이 구동되도록 하여 주므로서 주변이 아무리 어둡더라도 상기 피사체 확인수단의 불빛을 이용하여 화인더를 통해 피사체의 구도를 설정할 수 있게 되어 제품의 신뢰도를 더욱더 향상시킬 수가 있는 것이다.Therefore, in the present invention, by adding an auxiliary lamp (L1), etc., which is a subject identifying means, to the existing compact camera, the ambient brightness detected by the ambient brightness detecting means is dark enough to compose the subject. When the shutter release stage 1 switch S1 for driving the automatic focus when the output voltage is less than the predetermined voltage is 'on', the subject checking means is driven so that no matter how dark the surroundings are, By using the light, the subject can be framed through the finder, further improving the reliability of the product.
