PURPOSE: To speed up the output of a three-dimensional graphics picture by selecting two-dimensional picture data corresponding to a picture determination parameter. CONSTITUTION: When a processing request is inputted, the picture determination parameter and a two-dimensional picture parameter stored in a two-dimensional picture parameter memory are collated with each other by a two-dimensional picture data selecting and judging means 15, and it is judged whether one two-dimensional picture data among the two-dimensional picture data stored in the two-dimensional picture data memory is to be selected or not. Then, the two-dimensional picture data corresponding to the picture determination parameter is selected from among the two-dimensional picture data stored in the two-dimensional picture data memory by a two-dimensional picture data selecting means 17. A picture selected in this way is sent to an output means 14. This output means 14 is provided with a picture display device, and a two-dimensional picture based on that two-dimensional picture data is outputted to this picture display device. |
