摘要

A small region panorama image group (I₁^P, I₂^P, I₃^P) is generated in advance. The small region panorama image group (I₁^P, I₂^P, I₃^P) includes images including a common shooting range, being composed of a plurality of common partially overlapped regions (A, B, C, D), and having independency from each other in each partially overlapped region (A, B, C, D). With the use of the small region panorama image group (I₁^P, I₂^P, I₃^P), a predicted background image is generated in which light source environment is the same as that of a shot target image.
