Image Blending - Christie DHD599-GS User Manual

Image blending

Adjust blend widths and settings to left, right, top and/or bottom sides to create a seamless multi-
projector stitched image. (Available only when optional Dual Processor Warp Module is installed.)
What is a Blend?
In simple terms, a blend appears as a gradient strip along an edge of a projected image. It is
darkest along the extreme edge of the image, and lightens nearer to the rest of the image (see
below).
How are Blends used?
In multiple-projector wall, complementary blends between neighboring images can compensate for
the extra "brightness" or intensity where these edges overlap. By controlling blend width and other
properties, you can achieve uniformity across the group of images. Visible overlaps will disappear,
as shown below.
Overlap
Blending regions can be defined on all sides – left, right, top and bottom. The same gamma curve is
used for all blending regions.
