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. Therefore, accurate polarization information can be acquired compared to a case where polarization information is generated on the basis of the polarization component image.

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 image data processing devices, image data processing methods, and programs. A frame data generation unit generates first frame data based on event data indicating a variation in an electrical signal of a pixel generating the electrical signal by performing photoelectric conversion during a first accumulation time from a first frame generation start time to a first frame generation end time, and second frame data based on event data occurring during a second accumulation time from a second frame generation start time to a second frame generation end time. A first frame period from the first frame generation start time to the second frame generation start time is set and supplied to the frame data generation unit. The present technology can be applied to, for example, a case where a frame data is generated from an event data output from a dynamic vision sensor (DVS).

Abstract: An information generation unit 30 acquires, from a polarization imaging unit 20, observation values in which polarization directions are at least three or more directions (m≥3). A noise amount calculation unit 35-1 calculates an amount of noise on the basis of an observation value in a first polarization direction. Similarly, noise amount calculation units 35-2 to 35-m calculate amounts of noise on the basis of observation values in second to m-th polarization directions. A polarization model estimation unit 36 estimates a polarization model by using the observation values for the respective polarization directions and the amounts of noise calculated by the noise amount calculation units 35-1 to 35-m. Thus, it is possible to calculate a polarization model that is robust against noise.

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.

The sensitivity difference correction is executed for Gr and Gb signals included the image signal, for example, an RGB signal, which is generated by the single plate-type image sensor through the color filter. A pixel value of a color filter unit which has the same color as a correction target pixel and is present in surroundings of the correction target pixel is acquired. An additional value is calculated by adding a difference between weighted mean pixel values “a” and “b” of two kinds of pixel groups “A” and “B” classified according to positions of pixels to the pixel value of the correction target pixel in which the weighted mean values correspond to distances of the pixel groups from the correction target pixel. A mean value of the pixel value of the correction target pixel and the additional value is calculated as a corrected pixel value of the correction target pixel.
