Abstract
PURPOSE:To make it possible to obtain a stable picture without flickering as a display picture on a cathode-ray tube even in case of the random determination of the display position of the picture on the cathode-ray tube. CONSTITUTION:Deflection-position signals from signal generators 1 and 5 are held by sample holders 2 and 6 by sample time signals and then added and subtracted to and from previous deflection position signals corrected by residual-flux erasing number generators 4 and 8 by adder-subtracters 4 and 8, where addition and subtraction for the residual flux generated by previous deflection-position signals are made before deflecting amplification processes 20 and 50, thereby driving deflecting coils 30 and 60. Consequently, a stable picture without flickering can be displayed on CRT70.
