Abstract
A carrier level balancing circuit in which a color aliasing signal occurring when a cameraman takes a picture of an object of an achromatic (black and white) color can be canceled completely. In a carrier level balancing circuit for a color camera formed of a CCD solid state image pickup device of an all pixel separately read out system, two-channel color signals output from the CCD solid state image pickup device are multiplied with independent balance coefficients at every line by multipliers while the balance coefficients are switched in a dot-sequential fashion. Also, values of these balance coefficients are set by a coefficient setting circuit in response to color temperature information. Thus, the carrier levels can be balanced over a range of color temperatures.
