Abstract: Systems, Methods, and Apparatuses for an image sensor and a control system to cooperate with each photodiode in individual pixels to allow multiple pixels in a set of pixels to operate in a different imaging-mode of operation simultaneously within multiple window regions of the image. The image sensor has multiple window regions each capable of operating in different operating modes. Each pixel contains multiple photodiodes. The imager is fabricated with an additional semiconductor layer containing one or more metallization layers for interconnections and providing active CMOS circuits for control.

Abstract: An imaging system for capturing light over a wide dynamic range and method for operating the same are provided. In some aspects, the method includes positioning an imaging pixel to image a scene described by light signals that extend over a wide dynamic range, and selecting a different integration time for at least two photodiodes in the imaging pixel based on light signals received by the imaging pixel, wherein the photodiodes are coupled to a sense node, and each photodiode is controlled using a different transfer gate. The method also includes performing a readout of the imaging pixel using a readout circuit connected to the sense node, wherein a capacitance associated with the sense node is modified during the readout of the at least two photodiodes.

Abstract: An image sensor having a set of pixels making up the image sensor to capture an image. Two or more pixels in the set of pixels each have an architecture that includes multiple photodiodes configurable to form an individual pixel. A control system can cooperate with the multiple photodiodes to form the individual pixel. Each of the multiple photodiodes can have a transfer gate electrically coupled to that photodiode. A common region can hold or transfer charge at least during or after an integration time. A read gate electrically coupled to the common region and a sense node, can supply charge from the common region through the read gate to the sense node.
