This invention enables a person to paint or draw directly into color television. No special probe or stylus is required since a person can use brushes or pens, fingertips, rubber stamps, or any drawing or painting object whatsoever. At the same time, a person can play his free hand over a piano-like keyboard to synthesize images by manipulating or altering the images or forms as they are introduced. It is applicable to graphic productions of all sorts, computer input-output graphic processing systems, for visualizing mathematical transformations, or for use with scanning lasers or electron microscopes that etch or score.
