Black Level Uplift
Black in the blended regions appears less dark than in the rest of the image. To
compensate for this, use this menu to raise the black levels of the rest of the image:
•
Set
All
to the required amount of black level correction. This will apply equal
correction to the black levels of all colors.
•
If necessary, use the individual color sliders (
Red
,
Green
and
Blue
) for fine
adjustment.
You may experience artifacts at the edges where the blended region of one projector
overlaps the
pond of mirrors
of its neighbor. In the example below, the blended image
comes from
two projectors
,
1
and
2
. Both images have black level uplift applied;
as a result,
artifacts
3
and
4
have emerged at the edges where the black level uplift
region of one projector overlaps the pond of mirrors of the other.
To remove the artifacts, you need to slightly reduce the size of the black level uplift region
of each projector so it does not overlap the pond of mirrors of the other projector.
•
Depending on your array, use
Top
,
Bottom
,
Left
and/or
Right
to reduce the black
level uplift size. In the example below, use the
Right
slider of the
projector on the
left
1
to remove the
artifact on the right
4
, and the
Left
slider of the
projector
on the right
2
to remove the
artifact on the left
3
.
