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.
