Image Overlap
Source images consist of a single HD image that has been split into multiple channels (see Figure 1.2) 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 in Figure 1.3. The width of
the blending region determines the amount of required image overlap and this must be programmable to support
different applications.

Edge Feathering
The overlapping image data in the blend region must be edge-feathered to support a seamless optical blend. The
transfer function must be programmable to support blend regions of different widths and adjust to different video
characteristics. A typical blend function is illustrated in Figure 4.
