Abstract
In an image processing apparatus, an image signal of a plurality of polarized lights is input, for each set of image signals corresponding to the polarized lights, a maximum value of polarization intensities of polarization components of the image signals and a polarization angle at which the maximum value of the polarization intensities is obtained are found, and a target area to which polarization reduction is to be applied is found based on the image signal and a statistical area is set in the target area. Representative intensity and angle which are modes of the polarization intensities and angles of the sets included in the statistical area are found, and first correction processing for correcting each image signal of the sets included in the target area is performed using the representative intensity and angle according to the polarization angle of the each image signal.
