Abstract: A 3D image sensor include a depth pixel and at least two polarization pixels adjacent to the depth pixel. The depth pixel includes a charge generation region in a substrate. The depth pixel is configured to generate depth information associated with a depth of an object from the 3D image sensor in a 3D scene based on detecting light reflected from the object. Each polarization pixel includes a photodiode in the substrate and a polarizer on the substrate in a light-incident direction. The polarization pixel is configured to generate shape information associated with a shape of a surface of the object in the 3D scene based on detecting light reflected from the object. The polarization pixels and the depth pixel collectively define a unit pixel. The respective polarizers are associated with different polarization directions.

Abstract: An image sensor includes unit pixels, and from among the unit pixels, a first unit pixel and a second unit pixel that are adjacent to each other each include a first tap having a first photo gate, to which a first signal having a first phase difference with respect to an optical signal is applied, and a second tap having a second photo gate, to which a second signal having a second phase difference with respect to the optical signal is applied. A location of the first tap in the first unit pixel and a location of the first tap in the second unit pixel, and a location of the second tap in the first unit pixel and a location of the second tap in the second unit pixel are symmetrical with each other based on one point between the first unit pixel and the second unit pixel.
