This paper describes a new methotl for si~perim-posing virtual objects onto an image of a real scene with correct shading and shadows. Unlike the previously proposed methods, onr method renders virtnal objects based on a real illnmination distrib11-tion. First, a ratliance distribntion in the real scene is determined from two omni-tlirectional images of the scene. Then the measl~rrd radiance distribi~tion is nsed for rendering virti~al ohjects snperimposed onto the scene image. The proposed method can synthesize a convincing image even for a complex radiance distribution where other methods ofteri fail. We successfi~lly tested the proposed method by using real images to demonstrate its effectiveness.
