A color image viewed from a virtual camera is generated. Next, a fog image is generated by adding a fog color to respective objects in accordance with distances from a position, which is represented by a Z value, of a player object to positions of the respective objects which are represented by Z values. Further, mask processing is performed so as to add to the fog image a predetermined fog color in accordance with distances from a predetermined reference pixel to pixels in a lateral and a longitudinal directions in the fog image. And an image into which the fog image and the color image have been synthesized is displayed as a game image.
