Example video processing systems and methods are described. In one implementation, compressed video data is received from a recording device. Additionally, metadata associated with the compressed video data is received such that the metadata includes frame-specific metadata associated with frames in the compressed video data. Further, an application program is received and configured to generate a real-time interactive experience for a user based on the compressed video data and the metadata associated with the compressed video data. A non-fungible token (NFT) is generated that includes the compressed video data, the metadata associated with the compressed video data, and the application program.

A head wearable display system comprising a target object detection module receiving multiple image pixels of a first portion and a second portion of a target object, and the corresponding depths; a first light emitter emitting multiple first-eye light signals to display a first-eye virtual image of the first portion and the second portion of the target object for a viewer; a first light direction modifier for respectively varying a light direction of each of the multiple first-eye light signals emitted from the first light emitter; a first collimator; a first combiner, for redirecting and converging the multiple first-eye light signals towards a first eye of the viewer. The first-eye virtual image of the first portion of the target object in a first field of view has a greater number of the multiple first-eye light signals per degree than that of the first-eye virtual image of the second portion of the target object in a second field of view.

In various examples, a head-mountable display (“HMD”) may include a light source to emit light across a target region of a wearer, a light sensor, and a circuitry operably coupled with the light source and the light sensor. The circuitry may operate the light source to periodically emit light across the light sensor. Based on a determination that a time interval since the circuitry last received a signal from the light sensor satisfies a threshold, the circuitry may trigger a remedial action to cause the light source to cease emission of light across the target region of the wearer.

The present invention relates to a near-eye display device. The a near-eye display device includes a display, a first lens disposed in front of the display so as to be spaced apart from the display by a predetermined distance, a dynamic aperture adjustment element disposed adjacent to the first lens to dynamically control an aperture size of the first lens and a horizontal position of the aperture on a plane perpendicular to an optical axis, a main optics lens disposed to be spaced apart from the first lens by a predetermined distance, and a control system configured to control the dynamic aperture adjustment element.

A head-mounted device (HMD) contains a display, an optics block, a redirection structure, and an eye tracking system. The display is configured to emit image light and provide it to an eye of a user. The optics block is configured to direct the emitted light in order to allow it to reach the eye. The eye tracking system contains a camera, an illumination source, and a controller. The camera is configured to capture image data using infrared light reflected from the eye. The controller is configured to use this image data to determine eye tracking information. The illumination source is configured to illuminate the eye with infrared light for the purpose of taking eye tracking measurements. The redirection structure is configured to direct infrared light reflected from the eye to the eye tracking system. In multiple embodiments, redirection structures may comprise prism arrays, lenses, liquid crystal layers, or grating structures.

A display uses a projector to project an image onto a holographic diffuser. The holographic diffuser scatters light of the projected image to at least one holographic element having optical power, which forms an image in angular domain for a direct observation by a user. The holographic diffuser and the holographic optical element, such as a freeform lens or a reflector, may be disposed on a transparent substrate in which the image light propagates. The architecture that immerses a display (HOE diffuser) and the eyepiece lens into the substrate may reduce the form factor of the system compared to the VR headset architecture, while being suitable for operation in AR configuration.

Display devices include waveguides with metasurfaces as in-coupling and/or out-coupling optical elements. The metasurfaces may be formed on a surface of the waveguide and may include a plurality or an array of sub-wavelength-scale (e.g., nanometer-scale) protrusions. Individual protrusions may include horizontal and/or vertical layers of different materials which may have different refractive indices, allowing for enhanced manipulation of light redirecting properties of the metasurface. Some configurations and combinations of materials may advantageously allow for broadband metasurfaces. Manufacturing methods described herein provide for vertical and/or horizontal layers of different materials in a desired configuration or profile.

Visual-inertial tracking of an eyewear device using a rolling shutter camera(s). The eyewear device includes a position determining system. Visual-inertial tracking is implemented by sensing motion of the eyewear device. An initial pose is obtained for a rolling shutter camera and an image of an environment is captured. The image includes feature points captured at a particular capture time. A number of poses for the rolling shutter camera is computed based on the initial pose and sensed movement of the device. The number of computed poses is responsive to the sensed movement of the mobile device. A computed pose is selected for each feature point in the image by matching the particular capture time for the feature point to the particular computed time for the computed pose. The position of the mobile device is determined within the environment using the feature points and the selected computed poses for the feature points.

A system for measuring speckle contrast includes: a head up display (HUD) system configured to output a predetermined image and having a first pixels per degree (PPD); an imaging colorimeter: having a field of view; positioned such that the predetermined image is in the field of view; having a second PPD that is at least 2.2 times greater than the first PPD of the HUD system; and configured to capture an image including the predetermined image; and a speckle contrast module configured to determine a speckle contrast of the HUD system based on the image.
