<p>PROBLEM TO BE SOLVED: To change a reflection image projected in an object even when tracking a moving object with a camera. SOLUTION: A reflection vector V1 corresponding to a vector from a viewpoint E1 to a point R1 on an object 60 is determined. Among texture images passing closely to the object and expressing the environment of the object determined corresponding to the inner surface of a cylinder 70 having a central axis extended in the moving direction, a reflection image correspondent closely to a point Q1 on the cylinder 70 on the extension of the reflection vector V1 is used as a reflection image part projected closely to the point R1 of the object 60. When moving the object 60 to a position 60A and the object 60A is tracked with the camera, a reflected image close to a point Q3 on the cylinder on the extension of a reflection vector V3 at a point R2 on the object 60A corresponding to the point R1 becomes a reflection image projected into the point R2.</p> |
