    Abstract: An image sensor may include an image pixel array with both image pixels to gather image data and phase detection pixels to gather phase information. The phase detection pixels may be arranged in pairs, with two adjacent pixels covered by a single microlens. The phase detection pixel pairs may be arranged in dashed lines, with image pixels interposed between each phase detection pixel pair. There may be only one image pixel interposed between each phase detection pixel pair. The phase detection pixels may all include color filter elements of the same color. The phase detection pixels may all include green color filter elements. The image pixels in the interrupted lines may include color filter elements that match the surrounding color pattern. The image pixels in the interrupted lines may all include color filter elements of the same color.

    Abstract: An image sensor may have an array of image sensor pixels arranged in color filter unit cells each having one red image pixel that generates red image signals, one blue image pixel that generate blue image signals, and two clear image sensor pixels that generate white image signals. The image sensor may be coupled to processing circuitry that performs filtering operations on the red, blue, and white image signals to increase noise correlations in the image signals that reduce noise amplification when applying a color correction matrix to the image signals. The processing circuitry may extract a green image signal from the white image signal. The processing circuitry may compute a scaling value that includes a linear combination of the red, blue, white and green image signals. The scaling value may be applied to the red, blue, and green image signals to produce corrected image signals having improved image quality.

    Abstract: An image sensor may include a non-rectilinear image pixel array, which may produce non-rectilinear image data. The image sensor may include a resampling circuit to convert the non-rectilinear image data into rectilinear image data that is optimized for displaying an image to a user. This image data may be corrected using defect correction circuitry, resilience filtering circuitry, and aberration correction circuitry in the image sensor, and demosaicking circuitry and color correction circuitry in an image signal processor that is coupled to the image sensor. Alternatively, the non-rectilinear image data may be sent to the image signal processor without converting it to rectilinear image data. For example, machine vision applications may use and interpret non-rectilinear image data directly. In these applications, the image sensor and image signal processor may include fewer components, as the resilience filtering circuit, resampling circuit, aberration correction circuit, demosaicking circuit, and color correction circuit may be unnecessary.

    Abstract: An image sensor may have an array of pixels that include nested sub-pixels that each have at least one respective photodiode. An inner sub-pixel of a pixel with nested sub-pixels may have a relatively lower effective light collecting area compared to an outer sub-pixel of the pixel within which the inner sub-pixel is nested. A pixel circuit for the nested sub-pixels may include an overflow capacitor and/or a coupled gate circuit used to route charges from the photodiode in the inner sub-pixel. The lower light collecting area of the photodiode in the inner sub-pixel, with optional flicker mitigation charge routing from the coupled gates structure, may reduce the size of the capacitors required to capture photodiode and photodiode overflow charge responses. Flicker mitigation charge routing using a coupled gates structure may allow an adjustable proportion of the overflow charge to be stored in one or more storage capacitors.

    Abstract: An image sensor may have an array of image pixels arranged in color filter unit cells that each have at least one red image pixel that generates red image signals, at least one blue image pixel that generate blue image signals, at least one clear image pixels that generate clear image signals, at least one infrared image pixel that generates infrared image signals, and optionally at least one green image pixel that generates green image signals. The image sensor may be coupled to processing circuitry that performs chroma demosaicking operations on the image signals. The processing circuitry may generate an infrared image using the infrared image signals and a luminance value using the clear, red, blue, and infrared image signals. The processing circuitry may perform point filter operations on the image signals based on the generated luminance value to produce corrected visible light image signals having improved image quality.

    Abstract: An image sensor may include an array of imaging pixels and an array of color filter elements that covers the array of imaging pixels. The array of imaging pixels may include visible light pixels that are covered by visible light color filter elements and near-infrared light pixels that are covered by near-infrared light color filter elements. The imaging pixels may be arranged in a pattern having a repeating 2×2 unit cell of pixel groups. Each pixel group may include a visible light pixel sub-group and a near-infrared light pixel sub-group. Signals from each pixel group may be processed to determine a representative value for each pixel group that includes both visible light and near-infrared light information.

    Abstract: A pixel may include an inner sub-pixel group and an outer sub-pixel group. The inner sub-pixel group may have a smaller light collecting area than the outer sub-pixel group and therefore be less sensitive to light than the outer sub-pixel group. This may enable the pixel to be used to generate high dynamic range images, even with the sub-pixel groups using the same length integration time. The inner sub-pixel group may be nested within the outer sub-pixel group. Additionally, one or both of the inner sub-pixel group and the outer sub-pixel group can be split into at least two sub-pixels so that the sub-pixel group can be used to gather phase detection data. Adjacent pixels may have sub-pixel groups split in different directions to enable detection of vertical and horizontal edges in a scene.
