Development of a Real-Time Registration Adjustment System for a Color Camera

This article describes the real-time registration adjustment system developed for a three-tube color camera. Until now, the amount of the “dynamic” registration error exceeded 0.1% in Zone 1 and sometimes 0.5% in Zone 3, degrading the picture quality. With this system, the errors are decreased to within 0.05% in Zone 1, and to 0.1% in Zone 3. For real-time operation, correction signals are calculated in 10 msec by the “curved surface approximation” method, and are sent to camera deflection circuits every 0.05 sec from a built-in microprocessor.
