Circuit for compensating for vertical distortion of image by modes in display
 A circuit for compensating for a vertical distortion of images by modes includes: a compensation position regulator for regulating a pulse width of a horizontal output signal by varying an integration value of an output pulse width of a horizontal output circuit, for adjusting an output position of the horizontal output signal; a compensation size regulator for selectively amplifying the horizontal output signal voltage whose output position has been regulated by the compensation position regulator, for adjusting the voltage amplitude of the horizontal output signal; and a modulation circuit including a primary circuit for receiving the horizontal output signal whose output position and size are regulated by the compensation position regulator and the compensation size regulator, and a secondary circuit for receiving a vertical output signal having a period variable by modes through one terminal thereof, the modulation circuit modulating the vertical output signal selected by modes with the horizontal output signal to a vertical deflection coil connected to another terminal of the secondary circuit and outputting he modulated vertical output signal.
