Abstract
System and method in which correction signals are computed and applied individually and automatically to eliminate aberrations produced by non-linearities in the deflection amplifiers, yoke and cathode ray tube of a television display. During a programming period, alignment signals are applied to the deflection circuits in place of the normal scan signal, and the position of the beam on the screen is monitored. When the beam is at predetermined points, the correction signals are computed, and these signals are stored. During normal operation of the television system, the correction signals are addressed in accordance with the beam scan signals, and the correction signals are combined with the scan signals to maintain the beam on the desired path.
