Abstract: An image displaying apparatus has a dual port memory with a plurality of memory fields. Picture data generated by an NTSC TV camera are sequentially inputted to the serial ports of the dual port memory and then read out via the serial ports to be transferred to a video monitor. Since the transfer of data between each serial port and the memory field associated therewith is effected in parallel, the transfer is performed during the blanking period of the video monitor. In a period other than the blanking period, display data are sequentially fed from one serial port to the video monitor, while video data are fed to the other serial port. During such an input/output period, graphic data generated by a graphic processor are randomly written to the memory via random ports. The graphic data and the picture data are stored in the memory fields to produce display data to be displayed on the video monitor.
