Abstract

본 발명은 주위조도에 의한 OSD문자색 절환장치에 관한 것으로서, 그 구성은 주위의 조도를 감지하도록 하는 조도감지수단(26)과, 주위의 조도량에 해당하는 컬러량에 대한 패턴이 메모리되어 있는 컬러패턴메모리수단(28), 텔레비전의 CRT상에 OSD문자를 표시하기 위한 OSD처리수단(30) 및, 상기 조도감지수단(26)에서 감지된 조도신호의 조도량에 의거하여 상기 컬러패턴메모리수단(28)에 메모리되어 있는 컬러패턴데이터를 독취한 후 그 독취된 데이터신호를 기초로 상기 OSD처리수단(30)에 제어신호를 인가하여 OSD 문자의 컬러량을 제어하도록 하는 제어수단(32)을 포함하여 구성된 것을 특징으로 하여, 텔레비전의 주위조도에 의한 밝기를 감지하도록 하여 주변이 밝을시에는 녹색계통의 칼라로 OSD문자를 표시하고 또한 어두울 시에는 노란색 계통의 칼라로 OSD문자를 표시하도록 하므로써, 보다 선명한 OSD문자가 CRT상에 표시되도록 하는 효과가 있다.The present invention relates to an OSD text color switching device based on ambient illumination, the configuration of which is the illumination sensing means 26 to detect the ambient illumination, and the color is stored in the pattern for the color amount corresponding to the ambient illumination amount The pattern memory means 28, the OSD processing means 30 for displaying OSD characters on the CRT of the television, and the color pattern memory means based on the illuminance amount of the illuminance signal detected by the illuminance sensing means 26; And control means 32 for reading color pattern data stored in the memory 28 and applying a control signal to the OSD processing means 30 based on the read data signal to control the amount of color of the OSD text. It is characterized in that it is configured to detect the brightness by the ambient light of the television so that when the surroundings are bright, the OSD text is displayed in green color, and in the dark, it is displayed in yellow color. By displaying the SD characters, there is an effect that the clearer OSD characters are displayed on the CRT.

Description

OSD text color switch for ambient light.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 주위조도에 의한 OSD문자색 절환장치가 적용되는 텔레비전의 블럭구성도이다.1 is a block diagram of a television to which the OSD text color switching device is applied according to the ambient light according to the present invention.
