Abstract: A polarization imaging unit 20 acquires a polarized image including polarization pixels with a plurality of polarization directions. An information compression unit 40 sets reference image information based on polarized image information of reference polarization pixels with at least a plurality of polarization directions in the polarized image and generates difference information between the polarized image information of each of polarization pixels different from the reference polarization pixels in the polarized image and the reference image information. In addition, the information compression unit 40 reduces the amount of information of the difference information generated for each of the polarization pixels with the plurality of polarization directions to generate compressed image information including the reference image information and the difference information with the reduced amount of information. An information decoding unit 70 applies a decoding process corresponding to the compression process of the information compression unit 40 to the compressed image information acquired through a recording medium 50 or a transmission path 60 to generate the polarized image and outputs the polarized image to a polarized image using unit 80.

Abstract: The present disclosure relates to an image processing apparatus and method that enables to correctly obtain an area of a main object at the time of auto focusing.A control block selects a local focus area from information of a taken image and supplies designated focus position information indicative of the selected local focus area to an image processing block. The image processing block executes a control operation related with focusing on the basis of object area information indicative of an area corresponding to two or more objects within an image and designated focus position information indicative of a designated focus position in this image. The present disclosure is applicable to an imaging apparatus, for example.

Abstract: Provided is a polarization imaging unit that acquires a polarization image using a lens. In a parameter storage unit of an information processing unit, 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 of the information processing unit corrects the change in polarization state due to the lens, using the parameters stored in advance in the parameter storage unit.

Abstract: A normal candidate information generation unit of an information processor generates normal candidate information for each pixel indicating, for example, a zenith angle, or an azimuth angle, or a zenith angle and an azimuth angle, on the basis of a polarization image in a plurality of polarization directions obtained by a polarization imaging unit. The in-plane pixel selection unit selects a plurality of pixels indicating the plane to be observed in the polarization image. A normal calculation unit calculates a normal of the plane to be observed on the basis of the normal candidate information of the pixels selected by the in-plane pixel selection unit.
