MISREGISTRATION CORRECTION FOR COLOR TELEVISION CAMERAS |
摘要 |
A color television equipment has a plurality of component camera tubes and means for bringing the rasters of the tubes into registration one with another. The time interval between signals produced from each of a pair of tubes when that tube scans an oblique boundary on a test card is used to provide a correction signal to effect registration. Correction signals are derived to correct misregistration in both line and field directions.
