Abstract: An image sensor includes a polarizer array and a depth pixel array. The polarizer array may include first to fourth unit pixels, which are arranged in a first direction and a second direction crossing each other, and may include polarization gratings respectively provided in the first to fourth unit pixels. The polarization gratings of the first to fourth unit pixels may have polarization directions different from each other. The depth pixel array may include depth pixels corresponding to the first to fourth unit pixels, respectively. Each of the depth pixels may include a photoelectric conversion device and first and second readout circuits, which are connected in common to the photoelectric conversion device.
