    Abstract: In an image capturing unit 20, an imaging element has a 4×4-pixel area in which: pixels including at least one pixel of every color component of a plurality of color components are polarization pixels of the same polarization direction; and pixels which are not the polarization pixels constitute a majority of the 4×4-pixel area, and are non-polarization pixels. The unpolarized component calculating unit 31 of the image processing unit 30 calculates unpolarized components for each pixel and for each color component by using pixel signals of polarization pixels, and pixel signals of non-polarization pixels that are generated at the image capturing unit 20. The diffuse reflection component calculating unit 32 calculates diffuse reflection components for each pixel and for each color component by using pixel signals of polarization pixels, and pixel signals of non-polarization pixels that are generated at the image capturing unit 20.

    Abstract: A correction information generation section 50 emits measurement light having uniform intensity onto a polarized image acquisition section 20 acquiring a polarized image. Further, on the basis of a measured polarized image acquired from the polarized image acquisition section 20, the correction information generation section 50 generates variation correction information for correcting sensitivity variations caused in the measured polarized image due to difference in polarization direction, and causes a correction information storage section 30 to store the generated variation correction information. A correction processing section 40 then corrects the sensitivity variations caused in the polarized image acquired by the polarized image acquisition section 20 due to the difference in polarization direction by using the pre-generated variation correction information stored in the correction information storage section 30. Therefore, the polarized image outputted from the correction processing section 40 becomes a high-quality polarized image with, for example, its sensitivity variations corrected.

    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: A polarization imaging section 20 includes polarized pixels in each of a plurality of polarization directions. The polarization imaging section 20 includes a polarizer. The polarization imaging section 20 outputs image signals of a polarized image to a defect detecting section 35 of an image processing section 30. In a case where a difference between a pixel value of a target polarized pixel generated by the polarization imaging section and a pixel value of the target polarized pixel estimated from polarization characteristics corresponding to pixel values of peripheral pixels in a polarization direction different from a polarization direction of the target polarized pixel is greater than a predetermined allowable range, the defect detecting section 35 determines that the target polarized pixel is a defective pixel. Therefore, it is possible to detect a defect of a pixel in the polarization imaging section that generates the polarized image.

    Abstract: [Object] The present technique relates to an image pickup device, an image pickup method, and a program that enables pixels having 4 types of spectral sensitivities to be controlled while changing exposure times.[Solving Means] The present technique is applicable to an image pickup device including pixels having 4 types of spectral sensitivities, that include pixels having a panchromatic spectral sensitivity and are arranged on an image pickup surface, pixels that realize a first exposure and pixels that realize a second exposure different from the first exposure being arranged on the image pickup surface with respect to the 4 types of spectral sensitivities. Further, a first line in which first pixels having the panchromatic spectral sensitivity are arranged in a two-pixel cycle in a specific direction and a second line in which the first pixels are arranged while deviating by one pixel from the first line in the specific direction are arranged alternately in a direction orthogonal to the specific direction, and pixels having spectral sensitivities different from the spectral sensitivity of the first pixels are arranged in a 2- or 4-pixel cycle in the specific direction for each of the spectral sensitivities and 2-dimensionally constitute a cyclic arrangement of 4×4 pixels in which the first spectral sensitivity pixels are arranged in a checkerboard arrangement.

    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.
