Abstract
A method for compositing a graphic image with a background image to produce translucent effects identifies a key signal for each portion of the graphic image. The key signal is varied according to the amount of translucency desired for the graphics image from completely transparent to completely opaque. When the graphic image is mixed with the background image, the key signal is used to define the ratio of the graphic image to the background image at each part of the graphic image to produce a mixed image output.
