<p>PROBLEM TO BE SOLVED: To highly efficiently and accurately restore a performance image having been displayed in power shutdown.SOLUTION: A performance control data management part 404 updates a performance image at prescribed timing on the basis of scenario data selected by a scenario lottery execution part 403. A restoration buffer 406 stores records each comprising a combination of a layer number representing a layer in which new image data are drawn and a performance ID corresponding to the drawn image data. When all layers of the performance screen is reset, all records of the restoration buffer 406 are deleted. Further, when the layer in which the image data are drawn is updated to other image data, a record representing the image data before the update in the restoration buffer 406 is deleted. In the power recovery, the respective records of the restoration buffer 406 are read out one by one, and image data represented by the performance ID of the read record are drawn in the layer represented by the layer number of the record.</p> |
