PURPOSE:To form electric circuits of a deflecting system as ICs and LSIs by constituting deflecting coils by multi-dividing coils and driving the deflecting coil by output signals from digital memories storing deflecting amount, correcting amount, etc. in accordance with the positions of the coils. CONSTITUTION:A synchronizing signal from a synchronizing separator circuit 4 is supplied to a processor 3 and also supplied to a clock signal generating circuit 5. The processor 3 reads out data in unit frame memories S1-S8 in nine digital memories M1-M9 repeatedly in every horizontal period in accordance with clock signals from the clock signal generating circuit 5. The read out one frame signal is supplied to matrix circuits 71-79 through decoders 61-69 and digitally processed by the matrix circuits 71-79 and signals including all the horizontal deflecting amount, miss convergence correcting amount, pin cushion correcting amount, etc. are supplied to coils L1-L9 through D/A converters 81-89 and driving circuits 91-99. |
