<p>A graphic image display device comprises a display processing section (2B) and a line buffer section (3). The display processing section (2B) is provided with a graphics ROM (26) for storing original graphics data (S17) of a plurality of graphic images. The display processing section (2B) reads original graphics data (S17) of a graphic image from the graphics ROM (26) according to a CPU I/F signal (S5) supplied from a CPU (1) as graphics processing control information, processes the original graphics data (S17) according to the CPU I/F signal (S5), and outputs display graphics data (S18). The line buffer section (3) temporarily stores the display graphics data (S18) to be displayed on a line of a display screen. The display processing section (2B) includes a mesh pattern generator means (28B) and a line buffer write control means (30). The mesh pattern generator means (28B) generates a mesh signal (S21) including masking information of a mesh pattern to be given to the display graphics data (S18) according to a mesh effect ON/OFF signal (S14). The line buffer write control means (30) controls ON/OFF of writing on the storing of the display graphics data (S18) in the line buffer section (3) according to the mesh signal (S21), thereby mesh effect is given to the display graphics data (S18) and mesh effect display is realized. According to the device, overlapping display of mesh effect graphics is made possible and transition of display graphics can be executed smoothly, without preparation of huge amount of graphics data or large capacity of the graphics ROM (26). <IMAGE></p> |
