Abstract

PURPOSE: To prevent occurrence of the flicker at the time of picture renewal by carrying out the writing to the memory to the receiver side during the horizontal blanking period and reading twice the picture of the same field to reproduce the picture in the form of the 1-frame picture.
CONSTITUTION: The picture of the 1st field and the picture of the 2nd field are written into addresses 1∼n and n + 1∼2n of 1-frame memory 7 during the horizontal blanking period via writing address counter 16 which counts the clocks synchronized with the velocity of the still picture transmission. Counter 11 and 12 generate the reading addresses of 1∼2n and 1∼n in synchronization with the displayed synchronous signals. Comparator 17 identifies in which field the writing action is carried out in the 1st or 2nd field, and the output selects the output of counter 11 or 12. Thus, the field of the side where no writing action is given is read out from memory 7.
