8.4.2 Black level adjustment
About adjusting the black level
The purpose of the black level adjustment is to align the black levels in the overlapped regions with the black levels in the other
regions.
This is needed because the black levels will be brighter in the blend zones, since multiple projectors will project on the same screen
area.
The size of the black level area is calculated automatically from the blend zones. This is done by using the start position and size of
each edge of the blend and adding an additional size of 8 pixels to reduce the effect known as "sea of mirrors".
You can also specify the offsets manually by turning off the automatic calculation. The black level value is adjusted in a 8 bit resolution
from 0 to 255.
How to adjust the black level manually
