Exposure control for image sensors
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.
