A main CPU extracts a contour and a contour candidate, which are visually important parts of an image to be rendered, according to, for example, polygon data representing an image of one frame. Further, a GPU performs rendering on data stored in a graphic memory according to the polygon data representing the image. Moreover, the GPU performs antialiasing on the contour and contour candidate extracted by the main CPU. Then, the GPU overwrites data representing the antialiased contour and contour candidate onto the data representing the image stored in the graphic memory.
