ABSTRACT:
A correction circuit is used with a horizontal deflection circuit, for the correction of an image distortion. The correction circuit comprises a line memory for sequentially fetching and storing one-field digital image data. The digital image data read out of the line memory is supplied to a D/A conversion circuit. This D/A conversion circuit converts the digital image data into an analog signal used for making a beam scan rate constant on the entire screen of a CRT. The data transfer rate used in both the line memory and the D/A conversion circuit is varied, with a clock supply rate adjusted by a frequency modulation circuit and an A/D conversion circuit on the basis of clock rate data.
