Abstract: An image pickup unit 20 has a configuration in which non-polarizing pixels and polarizing pixels are disposed, the polarizing pixels being provided per angle in at least two polarization directions. A demosaicing unit 50 generates a non-polarized image, and a polarization component image per polarization direction, from a captured image generated by the image pickup unit 20. A polarization information generating unit 60 generates polarization information indicating the polarization characteristics of a subject included in the captured image, from the non-polarized image and the polarization component image generated by the demosaicing unit 50. As described above, the polarization information is generated with not only the polarization component image but also the highly-sensitive non-polarized image not having a decrease in the amount of light.

Abstract: In an image capturing unit 20, an imaging element has a 4X4-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 4X4-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.

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: The present technology relates to a signal processing device, a signal processing method, a solid-state image sensor, an imaging device, an electronic device, and a program capable of generating an interpolated pixel such that occurrence of jaggies may be inhibited without blurring an image with a small calculation amount. Two candidate lines are set in each of a horizontal direction and a vertical direction in positional relationship symmetrical about a current pixel. The candidate lines are narrowed to two lines in the horizontal direction or in the vertical direction according to a pattern to which the current pixel belongs. Furthermore, searched pixels on the candidate line are narrowed according to the pattern. A weight value is calculated on the basis of similarity between a current block and a block in the same phase at the same distance from the block by block matching by a block to which the current pixel belongs.
