    Abstract: A method for processing an image includes obtaining a set of pixel values captured from a pixel array during an image capture frame. The set of pixel values includes pixel values for a set of asymmetric pixels having different directional asymmetries. The method further includes detecting, using the pixel values for at least the asymmetric pixels and the different directional asymmetries of the asymmetric pixels, a directionality of image flare; and processing an image defined by the set of pixel values in accordance with the detected directionality of image flare. In some embodiments, image flare may be distinguished from noise using the set of pixel values.

    Abstract: An imaging method includes imaging a scene using an imaging system, which includes an array of radiation sensing elements, including first sensing elements with symmetrical angular responses and second sensing elements with asymmetrical angular responses, interspersed among the first sensing elements, and optics configured to focus radiation from the scene onto the array. The method further includes processing first signals output by the first sensing elements in order to identify one or more areas of uniform irradiance on the array, and processing second signals output by the second sensing elements that are located in the identified areas, in order to detect a misalignment of the optics with the array.

    Abstract: Pixel binning is performed by summing charge from some pixels positioned diagonally in a pixel array. Pixel signals output from pixels positioned diagonally in the pixel array may be combined on the output lines. A signal representing summed charge produces a binned 2×1 cluster. A signal representing combined voltage signals produces a binned 2×1 cluster. A signal representing summed charge and a signal representing combined pixel signals can be combined digitally to produce a binned 2×2 pixel. Orthogonal binning may be performed on other pixels in the pixel array by summing charge on respective common sense regions and then then combining the voltage signals that represent the summed charge on respective output lines.

    Abstract translation: 通过对来自像素阵列中的对角定位的一些像素的电荷求和来执行像素合并。 从位于像素阵列中对角线的像素输出的像素信号可以组合在输出线上。 表示相加电荷的信号产生一个二进制的2×1簇。 表示组合电压信号的信号产生一个二进制的2×1簇。 表示合并的电荷的信号和表示组合的像素信号的信号可以数字地组合以产生二进制的2×2像素。 可以通过对相应的公共感测区域上的电荷进行相加，然后将表示相加的输出线上的相加电荷的电压信号合并，来对像素阵列中的其他像素执行正交分样。

    Abstract: An electro-optical device includes a laser light source, which is configured to emit at least one beam of light. A beam steering device is configured to transmit and scan the at least one beam across a target scene. In an array of sensing elements, each sensing element is configured to output a signal indicative of incidence of photons on the sensing element. Light collection optics are configured to image the target scene scanned by the transmitted beam onto the array, wherein the beam steering device scans the at least one beam across the target scene with a spot size and scan resolution that are smaller than a pitch of the sensing elements. Circuitry is coupled to actuate the sensing elements only in a selected region of the array and to sweep the selected region over the array in synchronization with scanning of the at least one beam.
