Patent ID: 8810702

Claim:
A method, comprising: resetting a pixel of an image sensor by sequentially applying a plurality of reset pulses to a gate of a reset transistor associated with the pixel, wherein the sequentially applied plurality of reset pulses collectively cause the reset transistor to reset the pixel to a reset level; and after said resetting, reading the pixel to obtain a pixel output indicative of photo-generated charge collected by the pixel since said resetting; wherein said resetting and said reading correspond to a single reset subsequent read of the pixel; and wherein said resetting the pixel comprises generating the plurality of reset pulses such that each reset pulse of the plurality of reset pulses transitions between: a first potential level that results in a region located under the gate of the reset transistor having a potential level that is less than a pinned potential of the reset transistor; and a second potential level that results in the potential level of the region located under the gate being greater than the pinned potential of the reset transistor.
