  • Patent number: 10707247
    Abstract: Various embodiments include methods and apparatuses for forming and using pixels for image sensors. In one embodiment, an image sensor having at least two pixel electrodes per color region, and having at least two modes is disclosed. The example image sensor includes a first, unbinned, mode; and a second, binned, mode. In the first, unbinned mode, the at least two pixel electrodes per color region are to be reset to substantially similar levels. In the second, binned mode, a first pixel electrode of the at the least two pixel electrodes is to be reset to a high voltage that results in efficient collection of photocharge, and a second pixel electrode of the at the least two pixel electrodes is to be reset to a low voltage that results in less efficient collection of photocharge. Other methods and apparatuses are disclosed.

  • Patent number: 10535699
    Abstract: An image sensor device includes a semiconductor substrate, including an array of pixel circuits, which define respective pixels of the device. A photosensitive layer is formed over the semiconductor substrate and configured to transfer charge to the pixel circuits in response to light incident on the photosensitive layer. An upper layer is formed over the photosensitive layer and is at least partially transparent to the light. Opaque partitions extend vertically through the upper layer in a checkerboard pattern aligned with the pixels in the array.

  • Patent number: 10516072
    Abstract: Optically sensitive devices include a device comprising a first contact and a second contact, each having a work function, and an optically sensitive material between the first contact and the second contact. The optically sensitive material comprises a p-type semiconductor, and the optically sensitive material has a work function. Circuitry applies a bias voltage between the first contact and the second contact. The optically sensitive material has an electron lifetime that is greater than the electron transit time from the first contact to the second contact when the bias is applied between the first contact and the second contact. The first contact provides injection of electrons and blocking the extraction of holes. The interface between the first contact and the optically sensitive material provides a surface recombination velocity less than 1 cm/s.

  • Patent number: 10506147
    Abstract: In various embodiments, an imaging system and method are provided. In an embodiment, the system comprises a first image sensor array, a first optical system to project a first image on the first image sensor array, the first optical system having a first zoom level. A second optical system is to project a second image on a second image sensor array, the second optical system having a second zoom level. The second image sensor array and the second optical system are pointed in the same direction as the first image sensor array and the first optical system. The second zoom level is greater than the first zoom level such that the second image projected onto the second image sensor array is a zoomed-in portion of the first image projected on the first image sensor array.
