Abstract

A dot matrix image display system displays a desired portion of an image in increased magnification on a dot matrix image display panel. A shift circuit functions to automatically shift the position of the enlarged portion in a predetermined direction on the dot matrix image display panel. The shift circuit determines not only the portion to be displayed with increased magnification but also a speed at which the enlarged display is shifted.
