Abstract
PURPOSE:To obtain optimum conditions independently by enabling the 1st driver circuit to drive and switch a picture display unit under the optimum conditions during the display of an animated picture, and the 2nd driver circuit to operate it under the optimum conditions when the animated picture is switched into the still picture. CONSTITUTION:A composite video signal inputted from terminal 6 is separated 7 into video signal 8 and horizontal and vertical synchronizing signals. Then, a pulse from clock pulse generating circuit 13 is mixed with horizontal and vertical synchronizing signal 9 by timing generating circuit 14, and maintenance pulse timing generating circuit 17 generates a maintenance pulse which varies in pulse width at the animation-display time and at the still-display time. Here, monostable multivibrators MDM and MDP drive the picture display unit under the optimum conditions during the animation display, and monostable multivibrators MSM and MSP drive the unit under the optimum conditions when the animated picture is switched to the still picture; and gate circuits G3...G5 and G6...G8 selects driver circuits corresponding to the animation display time and still display time. Consequently, The still picture and animated picture can be obtained independently under the optimum conditions.
