Patent ID: 8265478

Claim:
An imaging device, comprising: a photosensor that captures light projected onto the photosensor; an objective lens, wherein the objective lens that refracts light from a scene located in front of the imaging device to form a three-dimensional (3D) image of the scene in the imaging device; an optical element array positioned between the objective lens and the photosensor, wherein the optical element array comprises a plurality of optical elements, and wherein each optical element in the optical element array comprises: a microlens; and an aperture that increases depth of field of the microlens; wherein the 3D image of the scene extends in front of and behind the optical element array, wherein each optical element of the optical element array projects a separate portion of the 3D image of the scene onto a separate location on the photosensor, and wherein the separate portions of the 3D image projected onto the photosensor by the optical elements are in focus except for portions projected onto the photosensor from within a range extending in front of and behind the microlenses in the optical element array.
