Abstract
A depth pixel includes a photo detection region, first and second photo gates and first and second floating diffusion regions. The photo detection region collects photo charges based on light reflected by an object. The collected photo charges are drifted in a first direction and a second direction different from the first direction based on an internal electric field in the photo detection region. The first photo gate is activated in response to a first photo control signal. The first floating diffusion region accumulates first photo charges drifted in the first direction if the first photo gate is activated. The second photo gate is activated in response to the first photo control signal. The second floating diffusion region accumulates second photo charges drifted in the second direction if the second photo gate is activated.
