Abstract

PURPOSE:To enable to picture the decomposed picture for dynamic picture by setting the mutual interval of write-in operation time of a memory circuit greater than the vertical synchronizing signal period or to a multiple of one field. CONSTITUTION:The output of tuners 12a-12d are inputted to A/D converters 13a-13d and write-in/address generating circuits 15a-15d. The write-in address of memory circuits 14a-14d is determined with the output of address switching circuits 16a-16d. The output control pulse of the circuits 16a-16d is applied to a control terminal of the circuts 14a-14d via OR circuits 17a-17d. The video information read out from the circuits 14a-14d is edited to the video information for one field's share as a whole.
