Abstract
A polarization image capturing section 103 obtains a first polarization image containing polarization information. A polarization information obtaining section 104 obtains first polarization information from the first polarization image. An illumination control section 102 changes an illumination section 101 and again obtains a second polarization image by means of the polarization image capturing section 103. The polarization information obtaining section 104 obtains second polarization information from the second polarization image. A light source dependency estimation section 105 obtains light source dependency from the first and second polarization information obtained from the first and second polarization images. An area dividing section 106 performs an area division by using the polarization information and light source dependency information.
