Abstract: A method for displaying a near-eye light field display (NELD) image is disclosed. The method comprises determining a pre-filtered image to be displayed, wherein the pre-filtered image corresponds to a target image. It further comprises displaying the pre-filtered image on a display. Subsequently, it comprises producing a near-eye light field after the pre-filtered image travels through a microlens array adjacent to the display, wherein the near-eye light field is operable to simulate a light field corresponding to the target image. Finally, it comprises altering the near-eye light field using at least one converging lens, wherein the altering allows a user to focus on the target image at an increased depth of field at an increased distance from an eye of the user and wherein the altering increases spatial resolution of said target image.

Abstract: The present invention facilitates efficient and effective image processing. A network can comprise: a first system configured to perform a first portion of lighting calculations for an image and combing results of the first portion of lighting calculations for the image with results of a second portion of lighting calculations; and a second system configured to perform the second portion of lighting calculations and forward the results of the second portion of the lighting calculations to the first system. The first and second portion of lighting calculations can be associated with indirect lighting calculations and direct lighting calculations respectively. The first system can be a client in a local location and the second system can be a server in a remote location (e.g., a cloud computing environment). The first system and second system can be in a cloud and a video is transmitted to a local system.

Abstract: In an embodiment, an augmented reality display is provided that incorporates a prescription lens for the wearer. In an embodiment, an image is generated from a display and directed into the edge of the prescription lens, and the lens acts as a waveguide. The image is internally reflected within the prescription lens, and is directed to the wearer by an image combiner embedded within the prescription lens. In an embodiment, the augmented reality display can be adjusted for many common vision problems including myopia, hyperopia, astigmatism, and presbyopia.

Abstract: In embodiments of the invention, a method may include displaying an array of slits using a first light-attenuating spatial light modulator, displaying a pre-filtered image using a second light-attenuating SLM by attenuating rays of light originating from a surrounding environment to synthesis a near-eye light field, where the rays of light pass through the first and second light-attenuating SLMs, and selectively blocking the rays of light originating from the surrounding environment using the array of slits to generate a virtual image in said near-eye light field.

Abstract: System and method of displaying images in temporal superresolution by multiplicative superposition of cascaded display layers integrated in a display device. Using an original video with a target temporal resolution as a priori, a factorization process is performed to derive respective image data for presentation on each display layer. The multiple layers are refreshed in staggered intervals to synthesize a video with an effective refresh rate exceeding that of each individual display layer, e.g., by a factor equal to the number of layers. Further optically averaging neighboring pixels can minimize artifacts.

Abstract: System and method of displaying images in spatial/temporal superresolution by multiplicative superposition of cascaded display layers integrated in a display device. Using an original image with a target spatial/temporal resolution as a priori, a factorization process is performed to derive respective image data for presentation on each display layer. The cascaded display layers may be progressive and laterally shifted with each other, resulting in an effective spatial resolution exceeding the native display resolutions of the display layers. Factorized images may be refreshed on respective display layers in synchronization or out of synchronization.
