• Description of the early Image Processor, excerpted from the Macro Proto Proposal Tools

  The image processor was constructed under a grant for innovation in undergraduate program development at U.I.C.C. (University of Illinois at Chicago Circle) and is partially completed but functioning; its explicit instruction addresses perceptual learning of two-dimensional kinetic images and its implicit content embodies linear analogue generalized machines and video technology. It accepts moving images from television cameras, film trains or video tape recorders and routes them through modules that modify and combine images; it has operated about four months and was introduced to about seven people, with formal curriculum introduction planned for this fall.

• Principles of Electronic Image Processing - Switch, Mix, Compare Tools

  Overview of electronic image processing outlining imaging systems as signal generators, processors and controllers and describing switching, sequencing, mixing and comparing techniques. It defines switcher types (broadcast and distribution), timing and sync issues including internal versus external sync and vertical-interval switching; it explains sequencers, mixers, fades, wipes and keyers with clip thresholds, oscillator control signals and waveform-based patterns, and notes SEG/mixer re-entry. Switchers and mixers are identified as commercially developed prior to and during the 1950s.

• Computer Systems Approach to Video Art Tools

  A 1975 proposal to the New York State Council on the Arts and a 1977 report describe a computer-based video synthesis system for synthesizing, processing and controlling video images for artists. The documents list proposed and conventional components including spatial and intensity digitizer, function generator, digital memory, A/D and D/A converters, sync generator with genlock, time-base corrector, chroma keyer, colorizers, keyers and special-effects generators; they define interactive-compositional and automatic-production modes. The system specifies a 1,024-word 16-bit buffer, a DEC LSI-32 microprocessor with Teletype I/O and floppy drives, a 9.7552434 MHz clock phase-locked to a 3.579545 MHz subcarrier, and an X–Y module providing 512 pixels and 18 bits of timing.

• Final Report to the National Endowment of the Arts: Analog Computers Bibliography

  "Analog computers have been much more successful as tools for the creative artist than digital computers. Analog computers are quite successfully used in music and more recently, in video art. Most of the current work in digital computer art suffers from a real lack of fluidity in control, which is …
