AUTOMATIC REGISTRATION ADJUSTING SYSTEM ABSTRACT OF THE DISCLOSURE In a micro-processor based automatic registration compensation system for a multi-tube color television camera, the number of correcting points is increased by interpolation of a limited number of sampled error data. The sampling of errors, and generation of respective registration compensating signals therefrom are effected twice in respect to errors in the vertical direction and four times in respect to errors in the horizontal direction for video signals from a red pick-up tube and a blue pick-up tube, respectively, relative to a video signal from a green pick-up tube. The registration compensating signals thus obtained, particularly for the horizontal errors, are desirably applied to auxiliary deflection coils provided on each of the red and blue pick- up tubes.
