ABSTRACT:
A method of correcting position errors of points in a television picture formed from a plurality of individual pictures includes the steps of arranging a pattern of photosensors in the proximity of the television picture. The pattern of photosensors is sequentially illuminated with the individual pictures. The positions of the most brilliantly illuminated sensors for each individual picture are noted and correction values for each of the individual pictures are generated in accordance with the position of the most brilliantly illuminated sensors within the pattern. The correction values are stored and used to correct the positions points within the individual pictures.
