7.8.11.1 Description
What is Gray Level De
fi
nition?
When matching multi channel systems, the
white level
can be matched using
Dynacolor
and the
black levels
can be tweaked
using
Black Color Matching
. When comparing the gray levels of certain projector platforms there can be a signi
fi
cant difference in
the primary color distribution on different gray levels. This is typically the case for LCD and LCoS projectors; especially when they
reach a certain age they are more sensitive to this artifact.
GLD adjustment allows correcting the gray levels by tweaking the contribution of the primary colors to each gray level (i.e. color
balancing).
How does Gray Level De
fi
nition work?
GLD allows you to adjust the contribution of the primary colors to different gray levels — or zones — to match different display
channels to a reference channel.
Applying a correction in a certain zone also in
fl
uences the adjacent zones.
The hierarchical levels are selected in a way that the
fi
rst hierarchy level in
fl
uences the entire transition from black to white (0% to
100%) with the main correction done at 25%. Below you can
fi
nd the table of the hierarchy levels and their in
fl
uence zone.
