Abstract
An appartus for adjusting the correction amount of a horizontal linearity and suppressing the amplitude of a horizontal deflection current in an image display device. A switching element 11 is provided between both ends of an S-curve correction capacitor 5 connected in series to a horizontal deflection coil 4, and by turning on this switching element 11 during a horizontal retrace period to discharge the S-curve correction capacitor 5, and controlling also the ON time of this switching element 11, the linearity in the horizontal period is corrected.
