Abstract

Improvements in frame correction circuits for television receivers, comprising a line frequency generator; a line deflection coil coupled to said line frequency generator; and an image scanning deflection generator, characterized in that said circuits comprise circuit means coupled to said line deflection coil and to said image scanning deflection generator, sensitive to signals from said image generator. image scan deflection to vary the line deflection current in said line deflection coil at a rate of image scan deflection during successive retransmission intervals of the line deflection beam so as to correct the deformation of the plot or background on which the image is built.
