ABSTRACT:
A color temperature control circuit for use in a color television receiver includes a first differential amplifier which compares a luminance signal with a reference voltage and when the luminance signal drops below the reference voltage, it is so actuated as to derive a current from a green chrominance signal to reduce the green chrominance signal level, and the second differential amplifier which compares the luminance signal with the reference voltage and when the luminance signal drops below the reference voltage, it is so actuated as to derive a current from a red chrominance signal to reduce the red chrominance signal level. When the first and the second differential amplifiers are actuated, signal level of a blue chrominance signal is apparently increased to turn a white image to a bluish white image.
