IMAGE PROCESSOR, CONTROL METHOD FOR IMAGE PROCESSOR AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image processor for suitably performing performance of such a situation that a shadow expressed on an object surface is changed according to the attitude change of an object.

SOLUTION: A pseudo normal vector information storage part 60a stores attitude conditions relating to the attitude of an object and pseudo normal vector information for acquiring the pseudo normal vectors of each element of a texture image mapped on the surface of the object by associating them with each other. A pseudo normal vector acquisition part 64 acquires the pseudo normal vector of each pixel of the texture image, based on the pseudo normal vector information stored in the pseudo normal vector information storage part 60a so as to be associated with attitude conditions satisfied by the attitude of the object. A shading processing execution part 66 executes shading processing to the object surface based on the pseudo normal vectors acquired by the pseudo normal vector acquisition part 64.
