1. An image processing apparatus, comprising:
a same region detector configured to detect a same region of a processing target for each of a plurality of viewpoints from polarization images in a plurality of polarization directions for each of the plurality of viewpoints; and
an image processor configured to:
calculate a polarization degree of the same region for each of the plurality of viewpoints based on the polarization images in the plurality of polarization directions; and
perform reflection removal process on the same region of the processing target based on the polarization images in the plurality of polarization directions of a viewpoint of the plurality of viewpoints at which the calculated polarization degree is maximized.
