Abstract

본 발명은 텔레비전 수상기 또는 모니터를 사용할 때 일정시간 동안 화면의 상태 특히, 밝기가 급변할 경우 ABL신호의 레벨을 감지하여 화면의 브라이트니스, 콘트라스트, 틴트 등의 영상출력 조정레벨을 자동으로 조절하여 시청하는 사람으로 하여금 눈에 많은 피로가 쌓이는 것을 방지하도록 하는 텔레비전 수상기의 화면 맑기 자동조절방법을 제공함에 그 목적이 있다.The present invention detects the level of the ABL signal for a certain period of time when the television receiver or monitor is used, in particular, when the brightness changes suddenly, and automatically adjusts the video output adjustment level such as brightness, contrast, and tint of the screen to watch. It is an object of the present invention to provide a method for automatically adjusting the screen clearness of a television receiver to prevent a person from accumulating a lot of eyes.

상기한 목적을 달성하기 위한 본 발명의 방법은 텔레비전 수상기의 전원이 구동 상태에서 자동화면 상태 변경모드가 선택되었는지를 검색하는 자동화면 상태 변경모드 설정과정과; 상기 자동화면 상태 변경모드가 설정된 경우 소정시간내에 화면의 밝기가 급변할 경우 이를 감지하여 사용자에게 알리고 화면의 밝기를 다운시키는 자동화면 상태 변경과정으로 이루어짐을 특징으로 한다.The method according to the present invention for achieving the above object comprises the steps of: setting an automatic surface state change mode for searching whether the automatic surface state change mode is selected while the power of the television receiver is driven; When the automatic surface state change mode is set, the automatic surface state change process detects when the brightness of the screen suddenly changes within a predetermined time, informs the user, and lowers the brightness of the screen.
