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.
