Abstract
A same region detector detects a same region of a processing target for each of a plurality of different viewpoints from polarization images in a plurality of polarization directions acquired for each of the viewpoints. The polarization images in the plurality of polarization directions acquired for each of the plurality of different viewpoints are, for example, polarization images acquired by imaging over a period of a plurality of frames in which a positional relationship between the processing target and a polarization image acquisition unit that acquires the polarization images changes. A polarization degree calculation unit calculates a polarization degree of the same region for each of the viewpoints on the basis of the polarization images in the plurality of polarization directions. A reflection removal unit performs reflection removal processing on the same region of the processing target by using the polarization images in the plurality of polarization directions of the viewpoint at which the polarization degree calculated by the polarization degree calculation unit is maximized. A reflection component can be removed even when an angle between a plane direction of a reflecting surface and an imaging direction is not clear.
