PROBLEM TO BE SOLVED: To obtain an image, resulting from revising a lighting environment, on a photographing object. SOLUTION: Image data are acquired (step ST11), and a spectrum distribution of a lighting light at photographing is acquired from a multi-band sensor as lighting component data (step ST12). Then object color component data equivalent to spectral reflectance of the photographing object are obtained by using the image data and the lighting component data (step ST13). Then the obtained lighting component data and the obtained object color component data are stored in such a way that they are extracted respectively independently (step ST14). Thus, data denoting the effect of a lighting environment on an image and data denoting a component of eliminating the effect of the lighting environment from the image are individually stored. As a result, arbitrary lighting component data can be combined with the object color component data at reproduction, so as to obtain an image with the lighting environment onto the photographing object revised. |
