The purpose of the edge-blending process is to provide a smooth transition for the eye over
the blending region. To provide a smooth transition, identical image data from two different
projectors must be superimposed and the output from each projector must be edge
feathered to provide seamless optical mixing of the two source images. There are two
video processing functions that are required specifically to support wide-screen edge
blended displays:
Image Overlap
and
Edge Feathering
.

Image Overlap
Source images consist of a single HD image that has been split into multiple
channels, or a series of images from a multi-head graphics card. In either case,
the source images must be re-formatted to provide image overlap to support the
edge-blending process. The Image Overlap processing is illustrated below. The
width of the blending region determines the amount of required image overlap and
this must be programmable to support different applications.
