Electronic Control Unit for an Industrial Animation Camera
George W. Tressel, Stanley J. Andrews · Journal of the SMPTE · 1964
Industrial animation involves specialized camera controls, because a minimum of cel-by-cel animation is used. Instead, a great deal of cyclic, scratch-off, and build-up animation is involved. An electronic control unit with parallel time-delay controls greatly simplifies these operations. The usual elaborate animation camera log is replaced with a simple cue sheet. The board includes control for an aerial-image unit with provision for multiple-framing control over power-zoom and platen drives, and a timer for frame-by-frame power drives. Visual indicator controls provide an immediate check for camera modes and conditions to minimize possible error.
