Abstract
본 발명은 화상을 출력하는 투사기와 상기 투사기에서 출력된 화상의 광로를 1차 변경하는 프런트 미러와, 상기 프런트 미러에서 제공된 화상을 스크린에 결상시키기 위하여 화상의 광로를 2차로 변경하는 리어 미러와, 상기 리어 미러를 장착한 패널을 구비한 배면 투사형 티브이의 화상 보정 장치는 상기 스크린의 상하좌우에 화상이 결상되지 않는 부분에 광을 감지하는 센서로 구성되어 각각의 센서의 동작 유무에 대한 데이타를 신호 처리하는 화상 위치 감지부와, 상기 화상 위치 감지부에서 제공되는 각각의 센서 동작 유무에 대한 데이타를 제공받아 화상이 상기 스크린을 벗어나 결상되면 이를 보정하여 화상이 상기 스크린에 정확히 결상되도록 제어하하는 제어부와, 상기 스크린에 결상된 화상의 위치와 기준 화상의 위치에 대한 차이를 보정하기 위한 데이타를 저장하는 저장부와, 상기 스크린에 결상된 화상의 위치에 대한 차이를 보정하기 위하여 상기 제어부의 제어에 따라 상기 리어 미러가 장착된 상기 패널의 위치를 조절하기 위한 구동 신호를 출력하는 화상보정부를 구비한다. 따라서, 본 발명은 배면 투사형 티브이의 리어가 장착된 패널의 위치가 변동되어 화상이 스크린에 정확히 투사되지 않을 경우 상하좌우 방향으로 보정을 하여 스크린에 화상이 정확히 결상되도록 하여 고품질의 회상을 획득할 수 있다.The present invention provides a projector for outputting an image, a front mirror for primaryly changing an optical path of an image output from the projector, a rear mirror for secondaryly changing an optical path of an image to form an image provided from the front mirror on a screen, and The image projection apparatus of the rear projection type TV equipped with the rear mirror-mounted panel is composed of a sensor for detecting light in a portion where images are not imaged on the top, bottom, left, and right sides of the screen to signal data on the operation of each sensor. A control unit for controlling the image to be accurately imaged on the screen by receiving an image position sensing unit and data on whether each sensor is provided by the image position detecting unit and correcting the image when the image is out of the screen. And correcting a difference between the position of the image formed on the screen and the position of the reference image. A storage unit for storing data for outputting the data and a drive signal for adjusting the position of the panel on which the rear mirror is mounted under the control of the controller to correct a difference in the position of an image formed on the screen. Image correction is provided. Therefore, the present invention can obtain a high-quality recall by correcting the image in the up, down, left, and right directions when the position of the rear mounted panel of the rear projection TV is not accurately projected on the screen so that the image is accurately imaged on the screen. have.
