Automatic adjustment of the CRT screen image geometry parameters

In this article in the introduction the television screen image geometric distortion and the system for automatic adjustment of the CRT screen image geometry parameters that compensates distortions through adjustments in the compensational circuit in the TV set are described. Further, we extend cognitions, obtained with research work on the project of the automatic adjustment, mainly about the nature of geometry distortions of the television box. Then, mathematical model of image on the television screen, developed on the base of those cognitions, is represented and the cross-coupling compensation by use of mathematical model described.
