Image conversion method, texture mapping method, image conversion device, server-client system, and image conversion program

摘要

A shadow portion is distinguished in a given image (S 2 to S 6 ). On the shadow portion, a conversion process based on the brightness value of a pixel is performed (S 7 ), while on a portion other than the shadow portion, a conversion process based on the surface normal parameter which represents the surface normal of a photograph subject is performed (S 8 and S 9 ).
