Abstract
An image sensor includes a first imaging pixel for a first color having a photosensitive region disposed within a substrate of the image sensor and a second imaging pixel for a second color that is different from the first color having a photosensitive region disposed within the substrate. A refraction element disposed adjacent to the substrate, so that the refraction element refracts light of the first color to the photosensitive region of the first imaging pixel and refracts light of the second color to the photosensitive region of the second imaging pixel.
