Abstract
PURPOSE: To obtain a device which can be used as the standard of the white balance adjuster covering from the low to high brightness by giving multiplication with every color of red, blue and green to the output given from the means selecting the brightness and the means selecting the fixed color each.
CONSTITUTION: Either one of the brightness and color switches is selected via selectors 1 and 2 and through brightness selection switch Si to select several units of brightness and switch Sj to set the set white of the color TV and the adjustment allowance range out of the set white. And the voltage conversion is given to the corresponding data via D/A converters 3 and 4 according to R, G and B each. Then the multiplication is given to each of these output voltage through multiplier circuit 5 to decide the necessary voltage of R, G and B each. The voltage corresponding to R and B are delivered via gamma corrector circuit 6.
