Abstract
An image display system, for displaying an image on a screen in response to a position of a pointer, includes an image display unit for displaying the image on the screen, a detector for detecting coordinates responsive to the position of the pointer, and a display controller. The display controller controls the display to display an image indicating the position pointed by the pointer at position coordinates spaced by a predetermined distance from the position coordinates detected by the detector.
