<p>Graphic form data of a rendering graphic form and a rendering list for defining the specifics of rendering out of an external memory, where the graphic form data and the rendering list are stored in advance, to generate intermediate data and store the intermediate data in the external memory with the use of intermediate data generation means. Intermediate data scanning means detects a graphic form from the intermediate data stored in the external memory. Graphic form rendering means generates pixels of the detected graphic form from the graphic form data stored in the external memory to render an image. The rendering image is written and held in a buffer that has a multi-buffer configuration. Display output means reads the rendering image stored in the buffer and outputs the read rendering image to a display device. The writing in the buffer and the reading out of the buffer are executed alternatingly.</p> |
