Claim 7:
8. A method, comprising:
scanning, by a projector under control of a controller, an image of a scene to a subject's eye, wherein the projector comprises a plurality of light emitting elements and a focusing mechanism, wherein the focusing mechanism comprises a plurality of microlenses located in front of the plurality of light emitting elements, wherein the microlenses respectively correspond to respective ones of the light emitting elements to focus beams of light emitted by the respective ones of the light emitting elements at different focus distances, and wherein said scanning comprises:
determining, by the controller, a depth at each pixel in the scene; and
focusing, by the projector under control of the controller, each pixel at a focus distance that corresponds to the determined depth at the pixel as the image is being scanned by the projector,
wherein focusing each pixel at a focus distance that corresponds to the determined depth at the pixel as the image is being scanned by the projector causes objects in the scene that are intended to appear at different depths to be projected to a subject's eyes at correct depths.
