An object of the present invention is to process an image without a need to previously find out the initial value of a parameter representing an illumination condition and without a need for a user to manually input the illumination parameter. An image processing system includes a generalized illumination basis model generation means 300, a position/posture initial value input means 102, a face model generation means 103, an illumination basis model calculation means 301, a perspective transformation means 202, an illumination correction means 203, and a parameter update means 204. The generalized illumination basis model generation means 300 previously calculates a generalized illumination basis model. The face model generation means 103 generates an individual 3-dimensional shape and texture from the generalized 3-dimensional face model.; The illumination basis model calculation means 301 generates an individual illumination basis from the generalized illumination basis model using the same parameter. The parameter update means 204 searches for a parameter of a shape, texture, and position/posture to minimize the error when the input image is reproduced.
