Abstract: Abstract of DisclosureAn image processing apparatus includes a normal vector mapping section for dividing a surface of an object into a plurality of divided surfaces and generating a first normal vector pointing to the vertical direction of each of the divided surfaces, a luminance value mapping section for replacing the first normal vector of each divided surface with a luminance value associated with one of a predetermined number of second normal vectors, each associated with a different luminance value, which is most analogous in characteristic to the first normal vector, and a graphic processor for shading each divided surface according to the replaced luminance value.
