Adjusting the input balance

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.:

The source in question must be able to generate a white signal, ideally a 100% white (background) full screen pattern

The source in question must be able to generate a black signal, ideally a 100% black (background) full screen pattern

A B

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 changeover from min to max is indicated by the apparition of bright spots also called “digital noise”

An alternative to a full screen White/black pattern is the standard gray scale pattern, the white bar will be

used for white balance and the black bar for black balance.
