Claim:
1. An eyewear display system, comprising: a camera coupled to output a captured image in response to capturing an image of an object in a surrounding environment, wherein the camera includes an optical zoom to adjust a first magnification of the image prior to capturing the image; a projector coupled to receive the captured image to output a projected image; a polarizing beam splitter optically coupled to receive the projected image from the projector, the polarizing beam splitter further optically coupled to receive an actual view of the surrounding environment, wherein the polarizing beam splitter is optically coupled to output a combined view of the projected image combined with the actual view of the surrounding environment, wherein the combined view is to be directed to an eye of a user; an intensity controller optically coupled between the surrounding environment and the polarizing beam splitter to control an intensity of the actual view of the surrounding environment received by the polarizing beam splitter, wherein the intensity controller includes a liquid crystal polarization rotator (LCPR) disposed between a pair of polarizers, wherein a second polarizer in the pair of polarizers absorbs an s-polarization component of light from the actual view of the surrounding environment after the light passes through the LCPR; and a digital processor coupled to receive the captured image from the camera, wherein the digital processor is coupled to digitally scale the captured image to adjust a second magnification of the captured image provided to the projector, wherein the polarizing beam splitter is a first one of a plurality of polarizing beam splitters, wherein the eyewear display system further comprises a second one of the plurality of polarizing beam splitters optically coupled to receive illuminating light from an illuminating light source, wherein the second one of the plurality of polarizing beam splitters is adapted to direct the illuminating light to the projector, and wherein the second one of the plurality of polarizing beam splitters is optically coupled to direct the projected image from the projector to the first one of the plurality of polarizing beam splitters, wherein the eyewear display system further comprises a solid taper light tunnel disposed between the illuminating light source and a polarizer, wherein the solid taper light tunnel directs the illuminating light to the polarizer to enter the second one of the plurality of polarizing beam splitters, wherein a polarization of the projected image is orthogonal to a polarization of the actual view of the surrounding environment in the combined view output by the first one of the plurality of polarizing beam splitters that is directed to the eye of the user, and wherein the eyewear display system is adapted to be attached to eyeglasses to be worn by the user.
