Abstract
A display circuit for use in a hand held device is provided, which virtually expands the image displayed. The display circuit includes a display, a memory, a motion sensor, and a controller. The display has a predetermined size, and the memory has stored therein an image, which has an image size, that is larger than the size of the display. The motion sensor detects the movement of the hand held device and the corresponding movement of the display. The controller, which is coupled to the motion sensor, via prestored instructions, determines the current position of the hand held device and displays a portion of the image on the display, corresponding to the present position of the device. As the hand held device moves, the image being displayed on the display is panned an amount, which matches the movement of the hand held device.
