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.
