Abstract
Provided is an image sensor including a sensing transistor having two gates and a method of operating the image sensor. The image sensor may include a photoelectric conversion device, a sensing transistor which may have a first gate connected to a floating diffusion region in which charges generated from the photoelectric conversion region are stored and a second gate separated from the first gate, a reset transistor that may be connected to the floating diffusion region and may reset a potential of the floating diffusion region, a control voltage source that may supply a control applied to the second gate, and a column output line which may be connected to a source of the sensing transistor.
