<p><P>PROBLEM TO BE SOLVED: To prevent out of synchronism in rendition which is conducted by using a plurality of rendition control means. <P>SOLUTION: An initializing processing for setting initialization in a 33 ms timer, etc., is first performed in a main processing conducted by a display control CPU. Then a processing is changed into a loop processing for monitoring a timer interruption flag and a display control command received in the loop processing is analyzed. When a timer interruption occurs, the display control CPU 101 performs a counter updating processing, a display control process processing and a command transmission processing. A VDP performs control to update each picture frame once by the display control process processing which is conducted by 33 ms. Then the command transmission processing for transmitting a lamp control command, etc., is performed. Then the out of synchronism is prevented from occurring in rendition which is conducted by using the plurality of rendition control means. <P>COPYRIGHT: (C)2003,JPO</p> |
