PURPOSE: To omit a refreshing circuit of a memory control device, by shifting in order a picture element data at regular intervals and executing a write control, in a picture memory device for storing a picture which is similar to a static picture.
CONSTITUTION: An image to be photographed, which is similar to a static picture is photographed by a television camera 1, is A/D-converted 2, and a picture element data is stored in order in a picture memory 3' which has used a dynamic RAM. In order to store a picture element data which is A/D converted in order, a picture memory area is divided into plural area 3A, 3B, 3C, 3D, and each storage area is designated by common address information. A picture element data is also divided into each field, and is written in order and periodically to each corresponding storage area 3A, 3B, 3C, 3D by each field unit. As for a read-out control, immediately after the write-in, a data of an address corresponding to a write-in address of each storage area is read out.
