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.

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 polarized image acquisition section 11a acquires a polarized image of a target object having one or more polarization directions. A polarization parameter acquisition section 12-1 calculates the average brightness α of a polarization model on the basis of a non-polarized image subjected to sensitivity correction. Further, the polarization parameter acquisition section 12-1 calculates the amplitude β of the polarization model on the basis of the calculated average brightness α, pre-stored information regarding the zenith angle θ of the normal line of the target object, a refractive index r, and reflectance property information indicative of whether a subject is diffuse reflection or specular reflection. A polarization model detection section 13-1 is able to detect the polarization properties of the target object through the use of an image polarized in one or more polarization directions, by calculating the phase ϕ of the polarization model on the basis of a polarized image of the target object having one or more polarization directions, the average brightness α, and the amplitude β of the polarization model.

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: The polarization imaging unit generates a polarized image including pixels for each of a plurality of polarization components. The demosaicing unit calculates a pixel signal for each polarization component by using the pixel signal of the target pixel of the polarized image and the pixel signal of the pixel for each of the identical polarization components located near the target pixel. In one example, a low frequency component is calculated for each polarization component using the pixel signal of the pixel located near the target pixel for each of the identical polarization components. In addition, component information indicating relationship between the low frequency component of the polarization component of the polarized image and the pixel signal of the target pixel is acquired. Furthermore, the pixel signal for each polarization component in the target pixel is calculated based on the low frequency component and the component information for each polarization component.

Abstract: There are provided an apparatus and a method which generate an RGB image having less color noise and fewer false colors by inputting an RGBW image. The apparatus has an image sensor having an RGBW array, and an image processing unit which performs image processing by inputting a sensor image formed of an RGBW pixel signal output from the image sensor. The image sensor has a periodic array of a unit composition formed of each RGBW pixel, and has an array in which composition ratios of each RGB pixel within the unit composition are adapted to be the same as each other. The image processing unit converts a pixel array of the sensor image formed of the RGBW pixel signal, and performs at least either array conversion processing for generating an RGB array image or signal processing for generating each RGB image signal in which all RGB pixel values are set for each pixel position of the sensor image.
