Abstract

PURPOSE: To secure an easy correction for the difference of the color reproduction visually between cameras by securing the luminance correction for a specific color in case the color matching is given between several color TV's.
CONSTITUTION: The output of three color signals R, B and G given from the TV camera are applied to adders 101, 102 and 103 directly or via inverter 104. And the output of these adders are applied to non-adder circuit 105. Furthermore, the output of circuit 105 is applied to differential amplifier 106 along with the output of adder 103, and the output of amplifier 106 is connected to black/white clip circuit 107 as well as to dual differential amplifier 108. And the output of amplifier 108 is applied to adder 110 to be added with the output of Y matrix circuit 109 which supplies three color signals R, B and G. Thus the luminance correction is given to a specific color to secure an assured correction visually for the difference of the color reproduction between cameras.
