Abstract
In a color television camera of the type having a single image pickup tube with red, green and blue stripe filters for providing an electrical signal indicative of the image of an object, a luminance signal is separated by a low pass filter from the electrical signal, and a chrominance signal is also separated therefrom. A color difference signal is derived from the chrominance signal and is mixed with the luminance signal such that the polarity of the color difference signal is inverted relative to the luminance signal and a magnitude of the color difference signal is adjusted by a predetermined amount. The corrected luminance signal and a carrier chrominance signal are then combined to form a composite color video signal. A noise eliminating circuit is provided for improving the signal to noise ratio of the color difference signal used to correct the luminance signal.
