Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a display device by simultaneously enhancing the luminance of specific still picture and its background on a display screen gradually from a low state to a prescribed high state to reduce a memory capacity. SOLUTION: A CPU 2 reads out picture data of a stereoscopic character (pattern) which is framed in a single background color and is in a state in which it is illuminated by a weak light among pictures for opening stored in a ROM 3. And then, it supplies digital quantities indicating ratios of three primary colors of R, G, B of the picture to the source driver 9b of a liquid crystal display 9. Thus, at a time T1, the background and the patter are displayed dark on a liquid crystal display 9, that is, they are displayed in a low contrast on the display, but since the luminance of them become gradually high as a time is elapsed and it becomes a time T2, they become bright. Namely, since whitish parts become more whitish and the shade of the lower side in frames becomes clearer, the stereoscopic character of the pattern looms up in three dimensions out of the background.
