8.5.5 Black level setup procedure
Black level introduction
The Purpose of the black level adjustment is to adjust the black levels in the non overlapped areas with the
black level in the overlapped areas (Blend Zone).
This is a necessary function, due to the fact that the black level will be brighter in the blend zones, since
multiple projectors will add light in these zones.
The width of the black level area shall ideally be slightly larger than the width of the blend zone in order to also
compensate for the
“
sea of mirrors
”
phenomenon.
The figure below shows how this occurs in a side by side configuration without any correction of the black
level.
