摘要： A high-frequency image can be acquired at low computational cost at high speed.
A polarization optical unit 20 separates incident light into first polarized light and second polarized light to perform optical low-pass filter processing on the first polarized light and combines the first polarized light subjected to the optical low-pass filter processing and the second polarized light not subjected to the optical low-pass filter processing to generate combined light. A polarization image acquisition unit 30 includes a first polarizing pixel that generates pixel information on the first polarization image and a second polarizing pixel that generates pixel information on the second polarization image on the basis of the combined light. An image processing unit 40 performs a difference computation between the first polarization image and the second polarization image acquired by the polarization image acquisition unit 30 to generates the high-frequency image.

摘要： The present technology relates to a signal processing device, a signal processing method, and a detection sensor that enable detection of flicker information from an output indicating a luminance change.
A signal processing device includes: a count unit that counts a first count number, which is a count number of pixels in which a first luminance change in a positive direction is detected, and a second count number, which is a count number of pixels in which a second luminance change in a negative direction is detected, in an image output from a light receiving unit at a predetermined frame rate and indicating a luminance change; a coefficient generation unit that generates a coefficient corresponding to a time at which the luminance change is detected; and an integrating unit that integrates a multiplication result of the count number of the pixels and the coefficient. The present technology can be applied to, for example, an event detection sensor or the like.

摘要： The present disclosure relates to a solid-state imaging device, a method for driving the solid-state imaging device, and an electronic device that enable a solid-state imaging device capable of outputting a spatial difference to be realized at low cost.
A solid-state imaging device includes: a pixel including a photoelectric conversion element, a first capacitive element, and a second capacitive element; a reading circuit shared by a plurality of the pixels including a first pixel and a second pixel; and a vertical scanning circuit configured to control the pixel and the reading circuit, in which the vertical scanning circuit performs first control of simultaneously reading signal levels of different capacitive elements of the first and second capacitive elements in the first pixel and the second pixel. The present disclosure can be applied to, for example, a solid-state imaging device or the like in which a pair of capacitors is provided for each pixel, and these capacitors hold two signals of a reset level and a signal level to be subjected to AD conversion.
