Abstract
PURPOSE: To ensure the adjustment of white balance suitable for the color solidstate pick up unit of color difference sequential system, by applying the correction signal (luminance signal) of different amount every one horizontal period.
CONSTITUTION: In the output signal of the color difference signal LPF 10 of the color solidstate pick up unit, and in thescanning lines n(H) and n+1(H) of odd and even number of white balance, they are shifted (b) respectively 0.77R-Y and 1.23G-Y, then the color difference signal appears toward negative at n(H) and toward positive at n+1(H). On the other hand, the luminance signals (c) and (d) alternately fed to the amplifiers 17 and 18 every horizontal scanning are controlled for amplitude and polarity into waveforms (e) and (f). They are added to the signal (b) through the adders 19 and 20, and white balance is adjusted so that the color dirfference signal is zero(g). That is, the amplifiers 17 and 18 are controlled with the control circuit 21 adjustable externally every horizontal scanning of odd and even number corresponding to the color temperature of each illumination to completely match white balance.
