<p>Virtual three-dimensional object video signals V1 are generated by performing three-dimensional image conversion of source video signals, and two-dimensional object video signals V2 for visually representing the three-dimensional image conversion are generated by projecting the signals V1 upon an X-Y plane. Then three-dimensional shadow signals V3 and V5 are generated by projecting the signals V1 subjected to the three-dimensional image conversion upon a shadow plane, and two-dimensional shadow signals V4 and V6 corresponding to the signals V2 are generated by projecting the signals V3 and V5 upon the X-Y plane. Thus, the shadow signals with respect to the object video signals subjected to the three-dimensional image conversion can be generated through arithmetic operation.</p> |
