  • Patent number: 4371893
    Abstract: A system of video communication which allows the production of a graphic creation which can be transmitted by television receivers at some distance, comprises a projector which projects images on the bottom surface of a screen, through a partly reflective mirror. The image on the screen is fed through this mirror to photographic means which are connected with a storage, recording and/or reproduction system. The screen comprises a semi-transparent sheet which can be provided with a photosensitive coating. The image projected from below onto the screen is visible for an operator who can modify it from above the screen. Another embodiment of screen comprises a transparent lower sheet and a translucent upper sheet of distinctively different colors, with particulate material between them. Pressing with an instrument on the upper sheet displaces the particulate material and temporarily prints on the lower sheet the pressed image of the upper sheet.
