Image Blending - Christie DHD635-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.
Image blending is only available for DWU635-GS and DHD635-GS.
What is a blend?
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?
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 disappear, as shown below.

Blending regions can be defined on all sides
used for all blending regions.
