<p><P>PROBLEM TO BE SOLVED: To strictly prevent lost frames while improving the processing efficiency in the processing of the images by the double buffering. <P>SOLUTION: In the game machine, a CPU for the control of the performances reads out the image data based on the display control execution data out of the process data. The background image data read out is developed in any of two background frame buffers and the state of the background buffer indication flag is switched while the special pattern image read out is developed on any of two front frame buffers and the state of the front buffer indication flag is switched. In the game machine, a synthetic image is generated by synthesizing the background image data developed on the background frame buffer corresponding to the state of the background buffer indication flag and the special pattern image data developed on the front frame buffer corresponding to the state of the front buffer indication flag and the image signal is outputted for displaying as image the synthetic image thus generated. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
