| 1. An image processing method for representing to a user, by means of a display device, a combined image of an image of a
real object and a CG image, said method comprising:
a position detection step of detecting a position of a real object on a support base in a real world;
a management step of associating a plurality of levels of transparency for the CG image with respective locations on the support
base in the real world;
a combining step of generating a combined image by superimposing the CG image on the image of the real object, wherein the
CG image has a level of transparency which is the level of transparency that was associated with the location of the real
object in the management step; and
an output step of outputting the combined image for display on the display device.
