Introduction
Brightness uniformity
In a multi channel system the brightness can vary over the different channels/projectors. The brightness level can be matched using
:
1.
CLO: in this case the light power is matched over the different projectors, see
CLO
in the
Lamps
section
2.
Black level : this will act on the brightness of the “black” color of the image part situated outside the soft edge zones.
Internal black level versus Beta Planes
In the same way as for the soft edge adjustment (Internal vs Alpha planes) this black level adjustment can be
fi
xed
internally
by
using a dialog box or externally by uploading a user de
fi
ned
Beta plane
. This beta plane will contain the values for the brightness
offset
to be applied to the image.
Both methods will allow to compensate for the typical double brightness phenomenon in the soft edge zones by increasing the
brightness of the rest of the image.
