ABSTRACT:
Depth-based recursive video effects are generated by including depth information in the recursive loop. A combined depth coefficient signal output from a depth-based video combiner is modified by a recursive key signal from the recursive image output from the recursive loop. The resulting depth coefficient signal may then be blurred when a recursive blur effect is selected by using an appropriate filter corresponding to that used in the luminance and key recursive loops. The recursive depth coefficient signal from the depth recursive loop is used, together with the depth coefficient signal associated with an incoming image, to produce the priority signal used in the depth-based video combiner.
