Abstract:
Video communication apparatus includes a first diffusing screen comprising a layer of a transparent material in contact with a layer of a diffusing material such that the surface of the diffusing material not in contact with the transparent material forms a receiving surface that is substantially smooth and of a quality for accepting indicia, and the surface of the diffusing material in contact with the transparent material forms a transmitting surface. A video camera is positioned to provide a first video signal representative of images on the transmitting surface.
