    Abstract: Imaging apparatus (20) includes a photosensitive medium (22) and a bias electrode (32), which is at least partially transparent, overlying the photosensitive medium. An array of pixel circuits (26) is formed on a semiconductor substrate (30). Each pixel circuit includes a pixel electrode (24) coupled to collect the charge carriers from the photosensitive medium; a readout circuit (75) configured to output a signal indicative of a quantity of the charge carriers collected by the pixel electrode; a skimming gate (48) coupled between the pixel electrode and the readout circuit; and a shutter gate (46) coupled in parallel with the skimming gate between a node (74) in the pixel circuit and a sink site. The shutter gate and the skimming gate are opened sequentially in each of a sequence of image frames so as to apply a global shutter to the array and then to read out the collected charge carriers via the skimming gate to the readout circuit.

    Abstract: Apparatuses and methods for charge transfer in image sensors are disclosed. One example of an image sensor pixel may include a first charge storage node and a second charge storage node. A transfer circuit may be coupled between the first and second charge storage nodes, and the transfer circuit may have a first region proximate the first charge storage node and configured to have a first potential. The transfer circuit may also have a second region proximate the second charge storage node configured to have a second, higher potential. An input node may be configured to control the first and second potentials based on a transfer signal provided to the input node.

    Abstract: A pixel (700) in an image sensor can include a photodetector (708) and a storage region (712) disposed in one substrate, or a photodetector disposed in one substrate (738) and a storage region in another substrate (740). A buried light shield (710) is disposed between the photodetector and the storage region. A sense region (716), such as a floating diffusion, can be adjacent to the storage region, with the buried light shield disposed between the photodetector and the storage and sense regions. When the photodetector and the storage region are disposed in separate substrates, a vertical gate (714) can be formed through the buried light shield and used to initiate the transfer of charge from the photodetector and the storage region. A transfer channel (744) formed adjacent to, or around the vertical gate provides a channel for the charge to transfer from the photodetector to the storage region.

    Abstract: A method of operating an image sensor. Charge accumulated in a photodiode during a first sub-exposure may be selectively stored in a storage node responsive to a first control signal. Charge accumulated in the photodiode during a first reset period may be selectively discarded responsive to a second control signal. Charge accumulated in the photodiode during a second sub-exposure may be selectively stored responsive to the first control signal. Charge stored in the storage node from the first and second sub-exposures may be transferred to a floating diffusion node responsive to a third control signal.

    Abstract: An image capture device, pixel, and method of determining a focus setting for an image capture device are described. The image capture device includes an imaging area and a pixel readout circuit. The imaging area includes a plurality of pixels. The plurality of pixels includes multiple pixels in which each pixel of the multiple pixels includes a two-dimensional array of photodetectors and a microlens. Each photodetector in the array of photodetectors for a pixel is electrically isolated from each other photodetector in the array of photodetectors. A microlens is disposed over the array of photodetectors for the pixel. The pixel readout circuit includes, per pixel, a shared readout circuit associated with the array of photodetectors for the pixel and a set of charge transfer transistors. Each charge transfer transistor is operable to connect a photodetector in the array of photodetectors to the shared readout circuit.
