PROBLEM TO BE SOLVED: To provide a game machine which can partially display a character or letter while suppressing increase of a memory capacity by a certain degree.SOLUTION: A VDP 76 creates drawing data to a frame buffer 82 on the basis of a drawing instruction from a display CPU 72. Image data which is processed in creation of the drawing data is stored in a memory module 74 in advance. At the time, as the image data, symbol sprite data is stored, and α data for whole body for performing antialiasing to the symbol sprite data, is stored. In addition, α data for part which is one kind of the α data is also stored. By applying the α data for part to the symbol sprite data, partial display of a symbol corresponding to the symbol sprite data is performed.SELECTED DRAWING: Figure 8 |
