%0 Generic %1 crothers1989methoc %A Crothers, Paul %A Schaffer, Robert %B US Patent %D 1989 %K compositing keying segmentation %N 4,796,990 %T Methoc and Apparatus for Superimposing Scenes %X The device includes a camera having first and second imaging mediums. Polarlzed illumination is directed toward the camera from a screen mounted behind the foreground object. The foreground object blocks some polarlzed light from reaching the camera. Unpolarized light illuminates the foreground object, and the light reflects from the foreground object to the camera. A prism in the camera reflects polarized light to the first imaging medium and transmits the orthogonal components from the foreground object to the secon.d imaging medium. The image received by the fIrst imaging medium is combined with a background scene, and the image received by the second imaging medium is added to the combined image of the fIrst imaging medium and the background scene.
