Abstract
A distorted image (S) is acquired through a photographing operation using a wide-angle lens or an omnidirectional mirror. A cutting reference point (P) for cutting a partial cut region from the distorted image is set. The cut region is set according to the cutting reference point. An eye vector (n) corresponding to the cutting reference point is set with a photographing viewpoint of the distorted image as a base point. The cut region is shifted by a predetermined distance from the cutting reference point. The shifted cut region is transformed through image transformation to transform the distorted image into a planar regular image (T′) according to the eye vector. The shifted cut region (E′) is transformed.
