Abstract

An image sensor may include an array of imaging pixels arranged in rows and columns. A method of operating an imaging pixel is provided that includes accumulating charge in a photosensitive element, allowing the accumulated charge in the photodiode to overflow into a capacitor that is coupled to a reset transistor having a gate terminal configured to receive a reset control signal during an integration phase, and extending the dynamic range of the imaging pixel by dynamically adjusting the reset control signal from a first voltage level to a second voltage level during the integration phase. The reset control signal can be lowered from the first voltage level to the second voltage level in a discrete or continuous fashion such that a portion of the overflow charge in the capacitor represents a linear signal and a portion of the overflow charge in the capacitor represents a non-linear signal.
