Abstract
A polarization imaging unit generates, as polarization information, a polarization image including pixels in a plurality of polarization directions. An interpolation processing unit of an information processor performs interpolation processing using the polarization image obtained from the polarization imaging unit, and generates a polarization image for each polarization method. A polarization degree calculation unit calculates, for example, a polarization degree for each pixel as object surface information on the basis of the polarization image for each polarization method. A noise amount calculation unit calculates a noise amount for each pixel on the basis of the polarization image for each polarization method and the like. A polarization degree correction unit serves as an information correction unit, and corrects, according to the noise amount calculated by the noise amount calculation unit, the polarization degree that is object surface information calculated by the polarization degree calculation unit.
