ABSTRACT:
A system is described for automatic adjustment of a color television camera for correcting for geometrical errors in the raster and amplitude errors in the video. The system includes means for measuring the errors, positions, or amplitudes of the camera output signals at different locations of the red, green, and blue rasters for simultaneously providing detected signals representing the detected error positions or amplitudes of these locations to a signal processing means. The processing means selectively and separately processes said detected signals according to a plurality of algorithms for producing a plurality of correction signals. The correction signals are applied to the camera for adjusting the camera according to all of the correction signals before remeasuring the rasters.
