Abstract
본 발명은 종래 8가지의 OSD색상의 한계를 넘어 다양한 색상으로 OSD를 완전하게 컬러화하여, 밝기조정과 틴트조정 및 콘드라스트조정 동의 영상조정이나 음량조정과 같은 OSD를 이용한 텔레비젼 출력상태조정시에 각 조정단계별로 OSD문자가 다양한 색상과 밝기를 갖고서 표시될 수 있도록 하기 위한 OSD신호발생장치를 제공하기 위한 것이다. 이를 위해 본 발명은, 키입력부(10)의 제어키의 작동에 따라 튜너(12)를 제어하여 선국동작을 하거나 OSD출력을 제어하는 제어부(14)와, OSD데이터를 저장하기 위한 OSD저장부(18) 및, 상기 제어부(14)로부터의 제어신호에 따라 상기 OSD저장부(18)로부터 해당 OSD데이터를 독출하여 색신호와 휘도신호를 출력하는 OSD출력부(20)를 구비한 OSD신호발생장치에 있어서; 톱니파를 발생시키는 톱니파발생부(34)와, 상기 톱니파발생부(34)로부터의 톱니파를 입력받아 상기 OSD출력부(20)의 색신호(R',G',B')를 제어신호로 해서 스위칭선택한 신호를 OSD색신호(R",G",B")로서 출력하는 스위칭수단(32A,32B,32C)을 더 구비하여 이루어진 것을 특징으로 한다.The present invention completely colorizes the OSD in various colors beyond the limitations of the conventional eight OSD colors, and adjusts the TV output state using the OSD such as image adjustment or volume adjustment by adjusting brightness, tint adjustment, and contrast adjustment. It is to provide an OSD signal generator for displaying OSD characters in various colors and brightness in each adjustment step. To this end, the present invention, the control unit 14 to control the tuner 12 in accordance with the operation of the control key of the key input unit 10 to perform the tuning operation or to control the OSD output, and the OSD storage unit for storing the OSD data ( 18) and an OSD signal generation device having an OSD output unit 20 for reading out the corresponding OSD data from the OSD storage unit 18 and outputting a color signal and a luminance signal according to a control signal from the control unit 14. In; A sawtooth wave generator 34 for generating a sawtooth wave and a sawtooth wave from the sawtooth wave generator 34 are input to switch the color signals R ', G', and B 'of the OSD output unit 20 as control signals. And switching means (32A, 32B, 32C) for outputting the selected signal as OSD color signals (R ", G", B ").
