Display system with image magnification capability

Abstract

A display system includes a display unit provided with a screen for displaying images and an input unit for entering information. The display unit and the input unit include an infrared rays emitting section for emitting infrared rays and an infrared rays receiving section for receiving the infrared rays, respectively. The system further comprises a measuring section and a timer section. These sections measure the time which the infrared rays take to travel from the infrared rays emitting section to the infrared rays receiving section, and translate the time into the distance between the input unit and display unit. A magnifying section determines a magnification rate on the basis of the distance and a standard distance, generates a magnified image by, on the basis of the magnification rate, magnifying part of an image the entire of which is to be displayed on the screen in the case of the standard distance, and makes the display unit display the magnified image on the screen.
