Abstract: A depth pixel of a three-dimensional image sensor includes a first photo gate which is turned on/off in response to a first photo control signal, a first photo detection area configured to generate first charges based on a received light reflected from a subject when the first photo gate is turned on, a first transmission gate which is turned on/off in response to a first transmission control signal, a first floating diffusion area configured to accumulate the first charges generated from the first photo detection area when the first transmission gate is turned on, and a first compensation unit configured to generate second charges which are different from the first charges based on ambient light components included in the received light to supply the second charges to the first floating diffusion area.

Abstract: A depth pixel of an image sensor includes a depth sensing element configured to generate first charges that are photo-electrically converted from a light reflected from an object, a first floating diffusion node configured to receive the first charges from the depth sensing element, a second floating diffusion node configured to output second charges corresponding to a component of a reflection light where a component of an ambient light is cancelled, and an ambient light cancellation circuit configured to detect the ambient light to control a barrier level of a charge transfer path between the first floating diffusion node and the second floating diffusion node in response to the ambient light.

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.
