The alterations of the three color signals will happen independently i.e. the colors will end to be unbalanced.

The objective of input balancing
The objective in input balancing is to “set” the same black level and the same white level for the three colors of a particular input
source.
Black level setting : brightness
White level setting : contrast
The same absolute black and white level for the three colors allows the same reference for brightness and contrast control of the
picture!
These two references also set the range in which the ADC will work for that particular source (this also explains why each input
balance setting is linked to a particular source and thus saved in the image
fi
le).
How can it be done ?
To balance the three color signals of a particular source there are conditions; in fact we must know the black and the white level of
the source i.e. :
1.
the considered source must be able to generate a white signal, ideally a 100% white (background) full screen pattern
2.
the considered source must be able to generate a black signal, ideally a 100 % black (background) full screen pattern

White balance : In the projector, we will set the contrast for each color until we get a 100% light output picture when projecting a
100% white image (image A)
Black balance : In the projector, we will set the brightness for each color until we get a 0% light output picture when projecting a
100% black image (image B).
The black balance can be done automatically with
Automatic Black level
