    Abstract: A polarization imaging unit 20 has a configuration in which each pixel group including a plurality of pixels is provided with a microlens and the pixel group includes at least three polarization pixels having different polarization directions, and the pixels included in the pixel group perform photoelectric conversion of light that is incident via the microlenses to acquire a polarization image. A polarization state calculation unit 31 of an information processing unit 30 accurately acquires a polarization state of an object by using a polarization image of the object acquired using the polarization imaging unit 20 and a main lens 15, and a correction parameter stored in advance in a correction parameter storage unit 32 and set for each microlens in accordance with the main lens.

    Abstract: A polarization imaging unit 20 generates, as polarization information, a polarization image including pixels in a plurality of polarization directions. An interpolation processing unit 31 of an information processor 30 performs interpolation processing using the polarization image obtained from the polarization imaging unit 20, and generates a polarization image for each polarization method. A polarization degree calculation unit 32 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 33 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 34 serves as an information correction unit, and corrects, according to the noise amount calculated by the noise amount calculation unit 33, the polarization degree that is object surface information calculated by the polarization degree calculation unit 32. The object surface information that is robust to noise can be obtained.

    Abstract: A polarization imaging unit 20 acquires a polarization image using a lens. In a parameter storage unit 32 of an information processing unit 30, parameters related to a change in polarization state due to the lens which are estimated in advance from polarization state information acquired by imaging a light source in a predetermined polarization state using the lens and polarization state information indicating the polarization state of the light source, for example, change parameters indicating the change in polarization state due to the lens or correction parameters for correcting the change in polarization state due to the lens are stored. A polarization state correction unit 33 of the information processing unit 30 corrects the change in polarization state due to the lens, using the parameters stored in advance in the parameter storage unit 32.
