PURPOSE:To simply and inexpensively output the color display signal of a different system from three colores (red, green and blue) by the color signals of any two colors of red, green and blue. CONSTITUTION:This device is provided with a micro processor 1 digitally outputting the signals of any two colors of red, green and blue and a blanking signal, an on-screen display switching circuit 2 inputting the two colors signals and the blanking signal from the micro processor 1 and generating and outputting three colors of red, green and blue and a brightness signal and a color signal output circuit 8 receiving the output of the on-screen display switching circuit 2 and outputting the color signals of three colors and the brightness signal to a cathode ray tube, and by adjusting the DC level of the blanking signal by a DC level switching means 6, the signal of the color different from three colors is outputted from the on-screen display switching circuit 2. |
