<p>PROBLEM TO BE SOLVED: To easily and speedily form an image reduced in jaggy. SOLUTION: A main CPU 4 extracts the visually important part of the image to be plotted, an outer line (and outer candidate line), for example, based on polygon data constituting the image of one frame, for example. GPU 8 plots data with respect to a graphic memory 19 based on polygon data constituting the image of one frame. A GPU 8 performs antialiasing processing on the outer line (and outer candidate line) extracted by the main CPU 4. The outer line (and outer line candidate) which is antialiasing-processed is overwritten on the image which is previously plotted in the graphic memory 19.</p> |
