Abstract
A switcher mixer architecture creates special effects such as a dissolve or a wipe from one priority structure of the elements of an image scene to a completely different prioritized ordering of those same or even other elements that comprise the same or a different image scene. The special effect can be thought of as a 'priority transition' in the sense that the priority of a set of input image signals can be transitioned from that of a 'from' image to that of a 'to' image. The switcher mixer architecture eliminates a soft border artifact from the special effect by allowing a border to be given its own priority as though the border were a separate image input as well as to couple together (1) a source, or 'from,' image having one or more elements; (2) a destination, or 'to,' image having one or more elements, which could be the same or different than the 'from' image elements; and (3) a border image for separating the source image and the destination image in an image display.
