ABSTRACT OF THE DISCLOSURE An improved camera and process of coding images and a product produced thereby is described in which an image of graphics is scrambled by operation of a pseudoscopic camera. The graphics and focal plane-type shutter are moved simultaneously relative to . an objective lens and a graticule so as to produce an image of the graphics which will appear inchoate to ordinary vision. The image can be unscrambled by viewing the same through a graticule of the same nature as that used in the scrambling process.
