  • Apparatus and method for converting pictures or images into video signals
    Patent number: 5027219
    Abstract: A camera, together with a light source, is pointed by means of a mirror system at a projection surface which lies on the apparatus or adjacent to it. Transmitted light pictures, such as slides, can be placed in front of the light source, the said pictures thus being reproduced on the projection surface and being recorded from there. Instead of such projected images, it is possible to illuminate and record articles. Connecting two pieces of apparatus with one another, each apparatus having a monitor, provides a universal video telephone.
