  • Imaging systems and methods for generating high dynamic range images
    Patent number: 11165977
    Abstract: An imaging system may include an image sensor having an image sensor. The image sensor may include an image sensor pixel array coupled to row control circuitry and column readout circuitry. The image sensor pixel array may include a plurality of image sensor pixels. Each image sensor pixel may include a photosensitive element configured to generate charge in response to incident light, a first charge storage structure configured to accumulate an overflow portion of the generated charge for a low gain signal and a second charge storage structure configured to store a remaining portion of the generated charge for a high gain signal. Each image sensor pixel may also include a dedicated overflow charge storage structure interposed between the first charge storage structure and a floating diffusion region.
    Type: Grant
