Abstract

본 발명은 수광 소자를 이용한 모니터의 화면 조정장치에 관한 것으로, 종래의 모니터의 화면 조정장치는 모니터에서 출력되는 화면을 카메라로 촬영하고 이를 화상 인식장치로 인식하여 다시 화면의 위치를 설명하기 위한 시리얼 데이타로 변환해야 하므로 화면을 조정하여 이에 사용되는 카메라나 화상 인식 장치 등이 고가이므로 이를 위한 장치의 가격이 올라가는 결점을 가지고 있었다. 본 발명은 모니터(MOnitor)의 CRT상에 디스플레이(Display)되는 화면의 외곽선의 밝기를 수광 소자(Photo Snser)를 이용하여 검출하고 이로부터 화면의 정상위치 여부 및 화면 모양의 정상여부를 판별한 후 화면이 CRT 상의 중앙에 위치하도록 조정할 수 있도록 된 것이다.The present invention relates to an apparatus for adjusting a screen of a monitor using a light receiving element. A conventional apparatus for adjusting a screen of a monitor photographs a screen output from the monitor with a camera and recognizes it as an image recognizing device. Since it is necessary to convert the data into data, cameras and image recognition devices used to adjust the screen are expensive, and thus the price of the device for this has a drawback. The present invention detects the brightness of the outline of the screen displayed on the CRT of the monitor using a photo Snser and determines whether the screen is in a normal position and whether the screen shape is normal. The screen can be adjusted to be centered on the CRT.
