Abstract
A method and apparatus to isolate the video image of an object, usually a human being, from its background for use in forming a composite image. The viewer's image, with its background, is captured in both visible light and infra-red. In the preferred embodiment, the visible light image is modified by replacing, from an independent visible image source, that area corresponding to the cold (non-viewer) areas of the infra-red image.
