Abstract
PURPOSE: To make it possible to obtain the same pickup-tube output as that at an initial adjustment time, by varying a target voltage according to the color temperature of an illuminating light source.
CONSTITUTION: Color output signals R, G and BB of electrode-divided pickup tube 51 are applied to color coder 53 through pre-amplifiers 52R, 52G and 52B to be made into a color signal. Targets TR, TG and TB of the pickup tube are applied with target voltage VT through an adjustment resistance and load resistance. Between terminals 55R and 55B, variable resistance 58 is connected and the middle terminal is supplied with target voltage VT. Consequently, the control voltage of targets TR and TB can be varied differentially. The color balance of the color temperature of the illuminating light source is adjusted previously by resistances 56G, 56R and 56B, so that when the color temperature of the illuminating light source changes, the color balance can be adjusted only by resistance 58.
