United States Patent [72} Inventor EdwinJ.Smura Webster. N.Y. [21] Appl. No 724,746 [22 Filed Apr. 29, 1968 [45] Patented July 20, 1971 (73] Assignec Xerox Corporation Rochester, N.Y.

[54] GRAPHICAL DATA PROCESSOR 3,480,943 11/1969 Manber ABSTRACT: A digital and analog signal responsive processor generates a visible display of alphanumerics, halftone, or vector information. The processor includes logic circuits for developing dynamic deflection fields in a display cathode-ray tube in response to a sequence of digital codes unique for a particular alphanumeric symbol such that the tubes electron beam is moved or scanned substantially only over the plurality of linear areas of the tubes screen which will collectively display the desired symbol. Additional circuitry is included to generate vectors of any length either at a uniform deflection velocity or during a uniform period of time. in addition, digital circuits are present which may reproduce halftone configurations in a dot-by-dot manner. Beam intensity and focus registers permit the alteration of these qualities of the electron beam as desired.
