PROBLEM TO BE SOLVED: To provide an image display device for a game machine which displays exciting changes in thrilling pattern images to attract players with prolonged enjoyment. SOLUTION: This display device sets a changing value for a specified frequency of vertical scanning signals (U1). The display area is scrolled on a background image in response to each shift of the vertical scanning signal to set the background image within the display area as background (U2). Multiple kinds of pattern images and right and left pattern images are set for each of the changing values (U3 and U4). Pattern pictures with changing forms are sequentially set for each changing value as intermediate pattern picture (U5). While a fixed changing value is given, multiple kinds of shocking images are sequentially set (U6). Information for constructing screens is generated to get the background images, the pattern images and shocking images superimposed on the screen (U7). Thus, images based on the information for constructing screens are generated to be displayed sequentially each time the vertical scanning signal shifts thereby realizing exciting changes in thrilling pattern images (U8 and U9). |
