摘要： Disclosed herein includes a system, a method, and a device for rendering an image through adaptive reprojection. A first reprojection can be performed to generate a portion of a first image of a first view of a virtual space at a first rate. An amount of change from the first view to a second view of the virtual space can be determined. A portion of a second image of the second view of the virtual space can be determined to generate through a second reprojection. The second reprojection can be performed at a second rate to the portion of the second image according to the amount of change from the first view to the second view of the virtual space.

摘要： Laser or narrow band light sources (e.g., red, green, and blue) are utilized to form left (e.g., R1, G1, B1) and right (e.g., R2, G2, B2) images of a 3D projection. Off-axis viewing of the projections which has the potential to cause crosstalk and/or loss of energy/brightness in any channel or color, is eliminated (or reduced to only highly oblique viewing angles) via the combined use of any of guard bands between light bands of adjacent channels, curvature of viewing filters, and selection of passband wavelengths that maximize usability of the passband as it “shifts” due to varying or increasing angles of off-axis viewing. Implemented with any number of light sources, the light sources selected may also be converted to showing 2D images where the additional light sources are utilized to affect a desirable increase in color gamut.

摘要： Light from an array of laser light sources are spread to cover the modulating face of a DMD or other modulator. The spread may be performed, for example, by a varying curvature array of lenslets, each laser light directed at one of the lenslets. Light from neighboring and/or nearby light sources overlap at a modulator. The lasers are energized at different energy/brightness levels causing the light illuminating the modulator to itself be modulated (locally dimmed). The modulator then further modulates the locally dimmed lights to produce a desired image. A projector according to the invention may utilize, for example, a single modulator sequentially illuminated or separate primary color modulators simultaneously illuminated.

摘要： A method for displaying virtual content to a user, the method includes determining an accommodation of the user's eyes. The method also includes delivering, through a first waveguide of a stack of waveguides, light rays having a first wavefront curvature based at least in part on the determined accommodation, wherein the first wavefront curvature corresponds to a focal distance of the determined accommodation. The method further includes delivering, through a second waveguide of the stack of waveguides, light rays having a second wavefront curvature, the second wavefront curvature associated with a predetermined margin of the focal distance of the determined accommodation.

The stereoscopic image display apparatus includes a polarizing beam splitter for spatially splitting image light emitted by a projector into at least one transmitted beam and at least one reflected beam based on polarized components, at least one modulator for adjusting the transmitted beam and the reflected beam such that the transmitted beam and the reflected beam have different polarization directions when a left image and a right image are projected by the transmitted beam and the reflected beam, an angle adjustment unit for adjusting the position on a screen on which the transmitted beam is projected in response to a first remote control signal, a remote-control alignment type reflecting member for adjusting the path of the reflected beam in response to a second remote control signal such that the reflected beam overlaps the transmitted beam projected on the position on the screen adjusted in response to the first remote control signal in order to form a single image, and a remote controller remotely connected to the angle adjustment unit and the remote-control alignment type reflecting member for transmitting the first remote control signal and the second remote control signal to the angle adjustment unit and the remote-control alignment type reflecting member, respectively.

摘要： A novel projection system includes first and second light sources (e.g., sets of lasers), a spatial light modulator (SLM) that receives light from the first light source, and a beam steering device that receives light from the second light source and steers the light to highlight regions of the SLM. The SLM then modulates the light from both light sources to generate a highlighted imaging beam which can then be projected on a viewing surface. The highlighted imaging beam can represent a highlighted 2D image or a highlighted left- or right-eye view of a 3D image. The projection system thus improves peak brightness in the displayed highlighted images without incorporating a separate highlight projector or other expensive equipment. Methods for highlighting projected images are also described.
