ABSTRACT:
Horizontal and vertical registration errors in a color television camera are automatically error corrected by detecting registration errors in live scenes. Each error is associated with the preselected region of the raster in which it was detected. The errors are separately collected for each region. An error waveform is generated from collected error values. The past history of registration errors is also used. A correction waveform is generated to correct the registration error by minimizing the error waveform. This automatic registration system is microprocessor controlled.
