Abstract

An image display apparatus has a display memory for storing a one-frame image, a mouse for pointing a desired point on a CRT display, a keyboard including a key for instructing display area displacement, and an MPU to control display area displacement in response to operation of the key by the operator. The cursor can be displaced to a desired point on the screen to aid efficient panning without frequent shifting of the display area.
