Abstract

PURPOSE:To increase the reproduction processing speed of image, by performing storage, on one hand, and readout, on the other hand, through the use of a plurality of buffer memories. CONSTITUTION:Two image sensors CCDs 1, 2 receive the clock signal from a pulse source 206 at the same time and video signal is picked up simultaneously. Video signal is stored in memories A, C with the 1st scanning and the video signal is stored in memories B, D with the 2nd scanning. The video signal stored is read out serially, first from the memory A and then the memrory C.
