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.
