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.

Abstract: An image sensor pixel includes a plurality of photodiodes, a shared microlens, and a plurality of microlenses. The plurality of photodiodes are arranged as a photodiode array with each of the plurality of photodiodes disposed within a semiconductor material. The shared microlens is optically aligned with a group of neighboring photodiodes included in the plurality of photodiodes. Each of the plurality of microlenses are optically aligned with an individual one of the plurality of photodiodes other than the group of neighboring photodiodes. The plurality of microlenses laterally surrounds the shared microlens.
