Abstract
An apparatus includes an acquisition unit configured to acquire first polarization information that includes a polarized light component and an angle component using luminance values of input images obtained by imaging light of a plurality of colors in a plurality of different polarization states, a correction unit configured to acquire corrected polarization information obtained by replacing at least part of the first polarization information in a specific area with second polarization information obtained using a luminance value of a specific color among the plurality of colors in the specific area in the input images, and a generation unit configured to generate an output image using the corrected polarization information. The polarized light component is a luminance component that changes according to polarization angles. The angle component is a polarization angle that maximizes the luminance value.
