  • Apparatus for controlling the luminance of video signals in character areas on an on-screen-display
    Patent number: 5815215
    Abstract: A video signal luminance control apparatus is provided, which includes an input portion for receiving a luminance signal of the video signal, a transistor with a collector receiving the input luminance signal input from the input portion, via a resistor, and a controller which is connected to the base of the transistor for outputting a control signal for controlling the on/off operation of the transistor in an area where an on-screen-display (OSD) character is displayed. A simple transistor receiving the control signal is used to control the luminance of a video signal in an area where an OSD character is displayed, thereby providing a luminance control apparatus for clearly displaying OSD characters.
