Abstract:
The chromatic aberration of the lens of a multi-tube color TV camera is separated into a linear component and a non-linear component. Horizontal and vertical deflection correction waveforms are generated in accordance with these two components. These two correction waveforms are superimposed onto horizontal and vertical deflection waveforms employed to deflect electron beams in said camera tubes. A registration error caused by the chromatic aberration of the lens is corrected with high accuracy by employing these correction waveforms.
