Abstract

본 발명은 리모콘키의 조작에 따른 OSD화면의 출력시에 시청자의 시청거리에 자동으로 화면의 밝기를 조정함으로써 시청거리가 멀더라도 시청자가 뚜렷하게 OSD화면을 인지할 수 있도록 해주는 OSD동작시 화면 밝기 자동조정기능을 갖춘 텔레비전 수상기에 관한 것으로, 안테나에 의해 수신된 방송신호를 근거로 영상신호를 처리하여 재생하는 영상처리수단과 키입력수단을 통해 입력되는 키신호에 따른 텔레비전 수상기의 동작상황을 나타내는 OSD발생수단을 구비한 텔레비전 수상기에 있어서, 시청자의 시청거리를 검출하기 위한 시청거리검출수단과, 상기 영상처리수단을 통해 출력되는 영상신호의 밝기 데이터가 시청거리에 따라 각기 다른 데이터로서 저장되어 있는 데이터저장수단 및, 상기 키입력수단으로부터 키신호가 입력되면 상기 OSD발생수단으로부터 생성된 OSD패턴의 화면출력을 제어함과 더불어 상기 시청거리검출수단으로부터 검출된 시청거리에 따라 상기 데이터저장수단으로부터 영상신호의 밝기 데이터를 독출하여 상기 영상처리수단을 제어하는 제어수단을 포하맣여 구성된 것을 특징으로 한다.The present invention automatically adjusts the brightness of the screen to the viewing distance of the viewer when the OSD screen is output according to the operation of the remote control key to automatically display the screen brightness during OSD operation so that the viewer can recognize the OSD screen clearly even if the viewing distance is far. The present invention relates to a television receiver having an adjustment function, the OSD including an image processing means for processing and reproducing an image signal based on a broadcast signal received by an antenna, and an operation state of a television receiver according to a key signal input through a key input means. In a television receiver having a generating means, a viewing distance detecting means for detecting a viewing distance of a viewer and data in which brightness data of a video signal output through the image processing means is stored as different data according to the viewing distance. The OSD means when the key signal is input from the storage means and the key input means; A control means for controlling the screen output of the OSD pattern generated by the control unit and controlling the image processing means by reading brightness data of the video signal from the data storage means according to the viewing distance detected by the viewing distance detecting means. Characterized in that configured.

Description
