Integrated-circuit imagers selectively multi-sample pixel array outputs according to luminance level indicated by an initial sample, avoiding the additional power/time required for multi-sampling in high-luminance, shot-noise-dominated conditions and, conversely, multi-sampling in readout-noise-dominated low-luminance conditions.

The present technology relates to a light receiving element, an imaging element, and an imaging device. A light receiving element includes an on-chip lens, a wiring layer, and a semiconductor layer arranged between the on-chip lens and the wiring layer. The semiconductor layer includes a first voltage application unit to which a first voltage is applied, a second voltage application unit to which a second voltage is applied, a first charge detection unit, and a second charge detection unit. The wiring layer includes at least one layer including first voltage application wiring configured to supply the first voltage, second voltage application wiring configured to supply the second voltage, and a reflection member that overlaps the first charge detection unit or the second charge detection unit, in plan view. The present technology, for example, can be applied to a light receiving element configured to measure a distance.

In an information compression unit 311, in an image capturing unit 121 (221), among a plurality of pixel output units that receives object light that enters without passing through any of an image capturing lens and a pinhole, pixel outputs of at least two of the pixel output units have incident angle directivity modulated into different incident angle directivity according to an incident angle of the object light. The information compression unit 311 performs compression processing to reduce an amount of data of pixel output information generated by the image capturing unit 121 (221). For example, by computation of a difference between set reference value information and the pixel output information, linear calculation of a set calculation parameter and the pixel output information, and the like, the information compression unit 311 reduces a word length of the pixel output information, and reduces the amount of data of the pixel output information generated according to the object light that enters without passing through any of an image capturing lens and a pinhole.

The disclosure relates to a filter array and to a method for processing image data in a camera. The camera is configured to receive light and generate image data using an image sensor having an associated filter array. The image sensor includes an array of pixels, each of which corresponds to a filter element in the filter array, so that each pixel has a spectral response at least partly defined by a corresponding filter element. The filter array includes a pattern of wideband filter elements and at least two types of narrowband filter elements. The method includes the step of generating a luminance image comprising a wideband filter element value that is calculated for each pixel of the image sensor.

In a solid-state image sensor that detects presence or absence of an address event, erroneous detection of the address event is suppressed. Each of a plurality of pixels executes detection processing for detecting whether or not a change amount of an incident light amount exceeds a predetermined threshold, and outputting a detection result. An abnormal pixel determination unit determines whether or not each of the plurality of pixels has an abnormality, and enables a pixel without an abnormality and disables a pixel with an abnormality. A control unit performs control for causing the enabled pixel to execute detection processing and control for fixing the detection result of the disabled pixel to a specific value.
