Abstract

A method of generating graphic designs from a light source by scanning the light source to generate a video signal, generating signals representing parameters of a raster signal and generating a raster signal from the parameter signals. The method further includes the steps of generating a modified video signal from the video signal and the raster signal, displaying the modified video signal as a visual display and reproducing the visual display as the graphic design. The system for performing the method includes a light box which is scanned by a television camera to generate the video signal. A special purpose computer is programmed with the parameters for defining the size, shape, position and structure of a raster signal which is then generated. The video signal and the raster signal are combined by the computer to generate the modified video signal to a display means such as a cathode ray tube. A still camera is utilized to photographically record the displayed signal as the graphic design.
