Abstract
PURPOSE: To eliminate the adjustment and the time changing by giving the correction to the position information at the digital stage, and thus to omit the adjustment at the exchange time of the correction amount setting circuit.
CONSTITUTION: The digital position information given from digital position information forming circuit 21 receives the correction amount set previously through fixed memory correction amount adder circuit 22 and is then supplied to the deflecting coil after D/A conversion 23 and necessary amplification 24. In this way, the correction is given to both X-and y-coordinates systems, thus ensuring the effective correction for the image distortion.
