<p>A rendering processing device includes a subpixel buffer (68) having a rendering region which corresponds to a display region of a display (55), a color buffer (69) that registers a color value of a pixel, and a Z buffer (70) for registering a Z value of the pixel, and renders the pixel in the rendering region in accordance with the color value and Z value of the pixel to be displayed. When there is a new pixel to be rendered, it is verified whether an empty region for registering the color value and Z value of the new pixel exists in the buffers (69) and (70), or not, and when no empty region exists, the color value and Z value of the new pixel and the registered color values and Z values are compared with each other, the most approximate color values or Z values are integrated together to produce an empty region. <IMAGE></p> |
