ABSTRACT:
This invention provides an automatic color converter for on-screen signals including a color television displaying the color signals of image signals provided from a color demodulation integrated circuit on a cathode-ray tube through a cathode-ray tube driver. The converter uses a level detector for detecting the level of the original color signals R, G and B for image signals provided through a color demodulation IC, a decoder for decoding eight selections according to the detected level state detected through the level detector, a stage for combining the output of the decoder using OR gates, and an on-screen driver for selecting the color signals R, G or B provided from the color demodulation integrated circuit in accordance with the input signal of the combination means and applying the selected signals to the cathode-ray tube. The effect of converting the color of an on-screen signal to be distinguished in accordance with the change of the color of the image signal may be attained according to the present invention.
