Abstract
PURPOSE:To attain a reading simultaneously with a writing by successively transferring picture data, which are written to respective memory area parts, to a serial access memory as parallel transferring data with the plural memory area parts as a unit and reading them. CONSTITUTION:The picture data, which are written to plural memory area parts MEM1-MEM3 to constitute an image memory main body 31, are transferred to a serial access memory 35 as parallel transferring data DM1-DM3 with respectively different timings. The said transferred picture data are read from the serial access memory 35 as reading data DATAOUT. Accordingly, while the picture data are serially transferred from the one part of the memory area parts MEM1-MEM3, writing data DATAIN can be written to the other memory area parts MEM1-MEM3. Thus, practically, the picture data are written to an image memory 13 and simultaneously, the written image data can be read neither too much nor too little.
