Abstract

An image sensor pixel comprises a subpixel and a polarization pixel. The subpixel includes a group of photodiodes disposed in semiconductor material, a shared microlens optically aligned over the group of photodiodes, and a subpixel color filter disposed between the group of photodiodes and the shared microlens. The polarization pixel includes a first photodiode disposed in the semiconductor material, an unshared microlens optically aligned over the first photodiode, and a polarization filter disposed between the first photodiode and the unshared microlens. The shared microlens has a first lateral area. The unshared microlens has a second lateral area less than the first lateral area of the shared microlens.
