ABSTRACT:
An object is to provide a game system, program and image generating method which can effectively generate an image having an edge line of higher quality. The image of an edge line EDL of an object OB is changed depending on a distance between the object and the viewpoint or the size of the perspectively transformed object OB. As the distance between the object and the viewpoint increases or as the size of the perspectively transformed object decreases, the color of the edge line of the object gradually becomes the second color. The color of the edge line begins to become the second color at a threshold value VTN. The color of the edge line is set to the second color at another threshold value VTF. As the distance between the object and the viewpoint increase or as the size of the perspectively transformed object decreases, the image of the edge line of the object is made more transparent. When the distance between the object and the viewpoint (or the size of the object) is substantially equal to a distance in the viewpoint follow mode, the color or translucency of the edge line is maintained substantially constant. When the distance between the object and the viewpoint is at the threshold value VTF, the image of the edge line substantially disappears. The image of the edge line is drawn in the outside or inside area of the object.
