Abstract: Implementations of camera architectures for combined eye-tracking and outward-tracking are provided. One example includes a near-eye device comprising: a frame comprising an arm; an eye illuminator disposed on the arm of the frame, wherein the eye illuminator is configured to project light to an eye of a user; an imaging system disposed on the arm of the frame, wherein the imaging system comprises: an image sensor; and a color filter array comprising: a first set of filters for allowing the projected light from the eye illuminator to pass; and a second set of filters for allowing visible light to pass; and a lens comprising an optical element for: directing the projected light from the eye illuminator to the eye of the user; and directing light reflected off the eye of the user to the imaging system.
