Abstract
An apparatus and method for suppressing color error components generated in a color television camera of the type in which color component signals representing first and second colors of a color image are recovered by utilizing a difference of phase relationship of modulated color signals, one of which changes in successive horizontal scan lines. In this apparatus and method, a color correction signal which indicates positions of color errors and provides preferred color error correction is produced from an unmodulated component of an output from a pick up tube by operating upon such component. The wave shape of at least one of a luminance signal which is derived from the unmodulated component of the output from the pick up tube and used to generate color signals and the color component signals recovered by operating upon a modulated component of the output is adjusted, preferably in accordance with the color correction signal, so that the color error components which are generated when the color component signals are recovered and which are included in the color component signals are suppressed at least in the color signals which are produced from the luminance signal and the color component signals during generation of a color video signal.
