Abstract

본 발명은 프로젝션 티브이 겸용 캠코더에 관한 것으로, 종래 캠코더는 촬영한 내용을 재생시켜서 보고자할경우 별도의 티브이가 있어야하며 뷰파인더를 통해서 재생시켜 볼수는 있으나 화면이 작아서 혼자서만 볼수있고 여러명이 동시에 감상할 수 없는 문제점이 있었다.The present invention relates to a projection TV combined camcorder, the conventional camcorder has to have a separate TV if you want to play the recorded content to see through the viewfinder, but can be seen through the viewfinder is small screen can be seen alone and multiple people can watch at the same time There was no problem.

본 발명은 이와같은 종래회로의 문제점을 감안하여 액정디스플레이에 인가되는 영상신호의 위상을 바뀌주는 스위칭회로를 구성하고 조명장치에 전압조정회로를 부가하여 광원의 밝기를 조절할 수 있게하고 대안렌즈를 프로젝션 겸용의 렌즈로 하여 프로젝션 티브이 기능을 갖도록한 프로젝션 티브이 겸용 캠코더를 창안한 것이다.In view of the problems of the conventional circuit, the present invention constitutes a switching circuit for changing the phase of an image signal applied to a liquid crystal display, and adds a voltage adjusting circuit to the lighting device to adjust the brightness of the light source and to project an alternative lens. It was the invention of a projection TV combined camcorder which has a projection TV function as a combined lens.
