ABSTRACT:
Apparatus and method for generating a correct CRT display suitable for photographing without adjustment, regardless of horizontal and vertical timing signals. Sawtooth current waveforms of constant maximum amplitude and "S" bending are generated through the horizontal and vertical windings of the deflection coils for the CRT display in order to produce a scan of constant width, height, and horizontal and vertical linearity.
