PROBLEM TO BE SOLVED: To show realistic vibratory motions of an image using a small quantity of data. SOLUTION: While a CPU 1020 moves a front surface image 1500 together with a background image 1501 offset upwards from the image 1500 by a distance corresponding to several dots, maximum movements of these image are displayed in such a manner that the maximum movement of the image 1500 (U1) differs from that of the image 1501 (U2) and then the image 1500 moved to its maximum movement and the image 1501 moved to its maximum movement are returned to their initial locations, respectively. Thus, the manner, in which the image 1500 is moved, differs from the manner, in which the image 1501 is moved, and hence vibratory motions, vibrations or the like or the image 1500 can be displayed realistically. |
