Abstract: <P>PROBLEM TO BE SOLVED: To provide technique in which high frequency video sequence is displayed on a matrix display while maintaining motion quality of an input source.   <P>SOLUTION: In order to display a video source having a higher frame rate than a conventional frame rate, a common portion (V<SB>x</SB>) being displayed by a low frequency f<SB>v</SB>/2 is extracted from two continuous pixels of two continuous video frames. On the other hand, individual portions (V<SB>1</SB>' and V<SB>2</SB>') of corresponding pixels are displayed by a correct high frequency f<SB>v</SB>. A time interval, in which the two frames are displayed, is divided into three subgroups. Two groups of the subfields having similar sizes display the individual portions and one group of a subfield being called a special code displays the common portion. Thus, flicker defect of a large region is eliminated from a PDP and actual high frequency video is displayed on the PDP without a frame drop.  <P>COPYRIGHT: (C)2004,JPO
