GRAPHIC SIGNAL DISPLAY APPARATUS AND METHOD FOR HAND-HELD TERMINAL

PROBLEM TO BE SOLVED: To provide a graphic signal display device for a portable terminal machine and its method for moving a graphic signal and displaying it by movement of the portable terminal machine when the portable terminal machine displays a predetermined graphic signal on a screen. SOLUTION: When the graphic signal is displayed on the screen, a camera 100 integrally disposed in the hand-held terminal photographs a predetermined object. Feature points of the object are extracted from an image photographed by the camera 100, and the feature points are utilized to detect a movement of the camera 100. The graphic signals are moved, enlarged, scaled down or rotated for display on the screen according to the movement of the detected object. Accordingly, the graphic signals can be scrolled, enlarged, scaled down or rotated simply by the movement of the hand-held terminal, thereby precluding a user from the inconvenience of manipulating the graphic signal every time the user intends to display the graphic signal.
