<P>PROBLEM TO BE SOLVED: To eliminate the possibility of the wrong estimation that a colored part where no mirror reflection is observed in taken image information has no mirror reflection in an object where the mirror reflection appears only in an extremely narrow angle range such as metal glossy matter. <P>SOLUTION: Taken image information for a subject matter 3 to which an illuminating light having a two-dimensionally spread luminance distribution is emitted from a light source 2 to the surface of the subject body 3 is acquired, and the surface attribute (particularly, reflecting characteristic) of the subject body is estimated on the basis of this taken image information and imaging environment information in the imaging (the information related to the luminance distribution of the illuminating light, the information related to the characteristic or setting of an imaging device 1 for performing the imaging, the information related to the position of the subject matter, the light source and the imaging device, the information related to the imaging direction by the imaging device, and the like). <P>COPYRIGHT: (C)2003,JPO |
