US Patent 10327633 Computational array camera with dynamic illumination for eye tracking

Methods and systems for eye tracking are disclosed. One such method obtains a plurality of images of the eye from an array camera and detects glint positions and a pupil edge of the eye in the plurality of the images. A distance from the array camera to the pupil edge may be estimated based on the glint positions. A pupil image may be generated based on selected ones of the plurality of images, the glint positions, and the estimated distance to the pupil edge. A pupil center position may be determined based on the pupil image and the glint positions.
