Abstract

본 발명은 텔레비전의 OSD신호 컬러제어장치에 관한 것으로, 텔레비전의 전원ON 시점에서 소정의 시청시간 간격으로 상기 OSD신호의 발생을 제어하는 제어부(12)와 그 제어부(12)의 제어하에 상기 전원ON 시점에서 활성화되어 일정한 시간마다 계시출력을 생성하는 타이머(38), 그 타이머(38)에서 일정한 시간마다 출력되는 계시출력에 기초해서 상기 OSD신호의 컬러를 변환하기 위한 OSD컬러변환부(40)를 포함하여 구성되고, 상기 OSD컬러변환부(40)는 상기 타이머(38)의 일정한 시간마다의 계시출력에 따라 상기 OSD신호의 현재 컬러레벨을 판별하는 컬러판별부(42)와, 그 컬러판별부(42)에 의해 지정되어 상기 OSD신호의 컬러를 변환하기 위한 R/G/B컬러제어부(44,46,48)을 구비하게 되고, 상기 OSD신호의 컬러변화는 CRT장치(36)상에 바그래프 형태로 표시되도록 한것이다.The present invention relates to an OSD signal color control apparatus for a television, wherein the control unit 12 controls the generation of the OSD signal at a predetermined viewing time interval at the time of power-on of the television, and the power supply is controlled under the control of the control unit 12. A timer 38 which is activated at a time point and generates a timed output at a predetermined time, and an OSD color conversion unit 40 for converting the color of the OSD signal based on the timed output output at a predetermined time by the timer 38. And the OSD color conversion unit 40 includes a color discriminating unit 42 for determining a current color level of the OSD signal according to a time output of the timer 38 at a predetermined time, and the color discriminating unit. And R / G / B color controllers 44, 46, and 48 for converting the color of the OSD signal, designated by (42), wherein the color change of the OSD signal is changed on the CRT device 36. It is intended to be displayed in graph form.
