Abstract

Abstract A distance sensor for detecting the distance between a display panel and an image viewer is provided on a display apparatus. An image signal supplied to the display panel is controlled based on the distance detected by the distance sensor to make a changeover between an enlarged image and a reduced image or between scrolling and stopping of a text or between moving and stationary display of a moving image. The speed of the scrolling and the speed of the moving display are stepwisely set according to the detected distance.
