This document relates to head mounted display devices. One example can include a layer of individually controllable pixels that can be energized to emit light and a layer of lenses that are physically aligned over the pixels. The example can also include a layer of shutters interposed between the pixels and the lenses and configured to be independently transitioned between a transmissive state and an opaque state to limit paths of the emitted light that reach the layer of lenses.

Video noise reduction for a video augmented reality system is provided. A head mounted display includes a display unit; a camera for generating frames of display data. A frame store is provided for storing previous frames of displayed information that was sent to the display unit; and a motion processor is provided in communication with the camera, display unit, and the frame store. The motion processor is operable to: identify an area of interest in a current frame of display data; match the area of interest to similar areas in previous frames stored in the frame store; rotate and translate the matched areas of interest from the one or more previous frames stored in the frame store to match the area of interest in the current frame; and average the prior matched areas of interest with the current area of interest to generate a displayed area of interest.

An achromatized metasurface lens that includes a color filter array and a metasurface lens located proximate to the color filter array. The color filter array includes a plurality of color filter elements for different colors of light. The metasurface lens includes a corresponding plurality of subsets of nanostructures based on the color filter array. Each respective subset of nanostructures is optically aligned with a corresponding color filter element. For example, a subset of nanostructures configured to modify a particular color of light may be optically aligned with a color filter element that filters light of the same particular color. The achromatized metasurface lens may be incorporated into a display system, such as a head-mounted-display. The display system may also include a narrowband display source tuned to the color filter elements in the color filter array.

Achromatized metasurface lens

A curved narrowband illuminant display is provided. A head mounted display is provided that includes a first lens having a first curvature. The first lens is focused on the curved display, and the display has a curvature such that the field curvature of the lens is corrected by the curvature of the display. In addition, a coherent fiber optic bundle sheet may be mounted on the display, wherein the coherent fiber optic bundle sheet has a curvature such that the field curvature of the lens is corrected by the curvature of the coherent fiber optic bundle sheet. According to another aspect, when a planar image is received, distortion for red, green, and blue images that comprise the planar image may be generated, undistorted red, green, and blue images may be generated, and the undistorted red, green, and blue images may be displayed.

Techniques for fabricating an image sensor chip having a curved surface include placing a bending substrate on a first surface of an imaging sensor chip. The first surface of the imaging sensor chip includes light sensors to generate electrical signals in response to receiving light. Fabricating also includes bending the bending substrate so as to impart forces on the image sensor chip to produce a curved imaging sensor chip. A second surface of the curved imaging sensor chip may be adhered to a backside substrate. The second surface is opposite the first surface. The bending substrate may be removed from the first surface of the imaging sensor chip.

Image sensor bending using tension

In some examples, techniques and architectures for operating a device that may be wearable, such as a head-mounted device, may be used for virtual reality applications. A processor of the device may operate by dynamically tracking the cornea, and thus the gaze direction, of a user's eyes. By tracking the gaze direction, retinal velocity of a display image projected onto the retina, measured in the retina coordinate frame may be computed. Display times of image frames viewable by the user may be modified based on the retinal velocity.

Adjusting image frames based on tracking motion of eyes

The subject disclosure is directed towards an image sensor that is controllable curved to adapt for differences in lens focal lengths. Variable data such as focal length data, measured curvature data and/or image quality data is received at a curve controller that curves the sensor based upon the variable data. In one aspect, a camera is provided with a lens having a variable focal length and a sensor capable of being dynamically curved. A curve controller receives image quality data and iteratively uses the image quality data to adjust the curvature to attempt to increase the image quality of a subsequent image to be captured.

Using a foveated camera for video augmented reality via a head mounted display is provided. A camera may be placed in a binning mode; a full frame binned image may be captured using the camera and the binning mode of the camera may be turned off. A region of interest may be selected within the full frame; the region of interest may be captured at a higher resolution than the resolution of the camera when in binning mode; the region of interest may be composited with the full frame binned image; and the composited image may be displayed.

Foveated camera for video augmented reality and head mounted display

The subject disclosure is directed towards a curved image sensor that is rotated in one or more rotational directions to compensate for camera movement, e.g., camera shake. In one aspect, sensors such as gyroscopes output camera movement data, which a controller uses to rotate the curved (e.g., hemispherical) image sensor about its center of curvature, e.g., via signals to electrical and/or magnetic movement mechanisms. Image processing may be used by the controller to rotate the image sensor.

Anti-shake correction system for curved optical sensor

Techniques for fabricating a semiconductor die having a curved surface can include placing a substantially flat semiconductor die in a recess surface of a concave mold such that corners or edges of the semiconductor die are unconstrained or are the only portions of the semiconductor die in physical contact with the concave mold. The semiconductor die can include through-die cut lines that can lead to substantially less tension in the semiconductor die as compared to the case where the semiconductor die does not include through-die cut lines. Accordingly, such through-die cut lines can allow for achieving relatively large curvatures.

Strain relieving die for curved image sensors

A system that comprises a receiver port to receive lens system design specifications; and a processor to: select a lens system type that includes one or more preliminary lenses, the selecting based, at least in part, on the lens system design specifications; from a lens database, select one or more catalog lenses to add to or replace the one or more preliminary lenses of the lens system type to construct a lens system; vary distances between or among the one or more catalog lenses and/or the one or more preliminary lenses of the lens system; and as the distances vary, determine optical behavior of the lens system.
