ABSTRACT:
An image processing apparatus sequentially reads image data corresponding to an area to be displayed from an image memory by use of an access address. This image memory stores the image data corresponding to the display area and other image data for other uses. The access address for the image memory is determined by the image processing apparatus such that the access address is increased from the predetermined start address in response to a scanning of a display screen. When the access address reaches at a predetermined boundary address representative of an address of the last image data corresponding to the display area of the image memory, the access address jumps to a predetermined jump destination address (such as the start address). Hence, the display will be started from the jump destination address, whereby the other image data can be prevented from being used for the display or from being destructed.
