Abstract
In the present invention, certain improvements are incorporated that permit removal of the backing color when its illumination is of non-constant color. In addition, an improved color logic is described that improves the simultaneous reproduction of fleshtones and green foliage in the same scene. A modified control logic is described that improves reproduction of red objects and fleshtones. A reversed window permits retention of objects whose color is identical to that of the backing. And, finally, a circuit is described which permits a super-imposing of titles or glow where said titles or glow may be made wholly transparent, semi-transparent or opaque.
