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.
