Abstract

In a highly accurate linear scan control for a CRT image display system useful for reproducing photographic images, distortion effects produced by system transients resulting from deflection drive amplifier circuits, are eliminated by introducing a step incremental increase in the input drive waveform at the start of the trace (scan) interval following the end of the retrace interval.
