Reduce Black Level Uplift Width (continued)
A detailed view of one of the projectors in a
two-projector array:
1
Black level uplift region
This image occupies the left half of a
two-projector array. Black level uplift
has created artifacts on the edges of
the blend region.
2
Artifact (left)
This artifact is caused by the
other projector’s pond of mirrors
overlapping the black level uplift
region of this projector. It can be
eliminated if the black level uplift
width of this projector is reduced.
3
Blend region
The area in the middle of the array,
where the two images overlap.
Black level uplift has not been
applied here.
4
Artifact (right)
This artifact is caused by this
projector’s pond of mirrors
overlapping the black level uplift
region of the other projector. It
can be eliminated if the black level
uplift width of the other projector is
reduced.
