PROBLEM TO BE SOLVED: To provide a game machine capable of partly displaying characters or letters while preventing a memory capacity from increasing to some extent. SOLUTION: Drawing data are developed on a frame buffer 82 based on a drawing direction from a display CPU 72 in VDP 76. Image data to be processed for the development of the drawing data are stored in a memory module 74 in advance. Symbol sprite data and α data for a whole for executing anti-alias to the symbol sprite data are stored as the image data in this case. α data for a part as a kind of the α data are also stored. Applying the α data for a part to the symbol sprite data allows symbols corresponding to the symbol sprite data to be partly displayed. COPYRIGHT: (C)2011,JPO&INPIT |
