Abstract
In a method of operating an image sensor, a noise voltage of a floating diffusion region is sampled after a reset voltage is applied to the floating diffusion region. A storage region, in which a photo-charge is stored, is electrically connected to the floating diffusion region after sampling the noise voltage, and a demodulation voltage of the floating diffusion region is sampled after the storage region and the floating diffusion region are electrically-connected. A voltage is determined based on the noise voltage and the demodulation voltage.
