Abstract
The image processing apparatus includes a calculator configured to calculate, using luminance values of one or more input images produced by photoelectric conversion of multiple polarized lights whose polarization angles are mutually different, an angle-dependent component at a specific polarization angle among angle-dependent components that are luminance components changing depending on the polarization angle. The apparatus further includes a producer configured to produce an output image using the angle-dependent component at the specific polarization angle.
