ABSTRACT:
A shadow portion is distinguished in a given image (S2to S6). On the shadow portion, a conversion process based on the brightness value of a pixel is performed (S7), 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 (S8and S9).
