Abstract: The present invention relates to the technical field of naked-eye 3D display, and provides a flicker-free directional backlight naked-eye 3D display device for multi-person viewing. An image control module converts image data into a 3D image, and a parallax 3D image is output to a first or Nth viewer through the cooperation of a display unit, a triangular prism-shaped microstructural directional beam-splitting film, and a directional backlight module, a quantity of viewers is determined by a human eye position signal in a display area collected by a human eye tracking module. The directional backlight module provides motion parallax, and the triangular prism-shaped microstructural directional beam-splitting film provides binocular parallax, so that the resolution is lost by only half in a horizontal direction and remains unchanged in a vertical direction, so that ultra HD 3D images can be implemented for one or more persons.

Abstract: A computing system includes a storage device and processing circuitry. The processing circuitry is configured to obtain an image frame that comprises a plurality of pixels that form a pixel array. Additionally, the processing circuitry is configured to determine that a region of the image frame belongs to a trigger content type. Based on determining that the region of the image frame belongs to the trigger content type, the processing circuitry is configured to modify the region of the image frame to adjust a luminance of pixels of the region of the image frame based on part on an ambient light level in a viewing area of the user; and output, for display by a display device in the viewing area of the user, a version of the image frame that contains the modified region.

Abstract: Examples of a light field metrology system for use with a display are disclosed. The light field metrology may capture images of a projected light field, and determine focus depths (or lateral focus positions) for various regions of the light field using the captured images. The determined focus depths (or lateral positions) may then be compared with intended focus depths (or lateral positions), to quantify the imperfections of the display. Based on the measured imperfections, an appropriate error correction may be performed on the light field to correct for the measured imperfections. The display can be an optical display element in a head mounted display, for example, an optical display element capable of generating multiple depth planes or a light field display.

Abstract: An electrically controlled spectacle includes a spectacle frame and optoelectronic lenses housed in the frame. The lenses include a left lens and a right lens, each of the optoelectrical lenses having a plurality of states, wherein the state of the left lens is independent of the state of the right lens. The electrically controlled spectacle also includes a control unit housed in the frame, the control unit being adapted to control the state of each of the lenses independently.

Abstract: A direct retinal projector system that provides dynamic focusing for virtual reality (VR) and/or augmented reality (AR) is described. A direct retinal projector system scans images, pixel by pixel, directly onto the subject's retinas. This allows individual pixels to be optically affected dynamically as the images are scanned to the subject's retinas. Dynamic focusing components and techniques are described that may be used in a direct retinal projector system to dynamically and correctly focus each pixel in VR images as the images are being scanned to a subject's eyes. This allows objects, surfaces, etc. that are intended to appear at different distances in a scene to be projected to the subject's eyes at the correct depths.

Abstract: Systems and methods for displaying an image across a plurality of displays are described herein. Pixel intensity values in the multifocal display are determined using correlation values and numerical iterations. An eye tracking system measures eye tracking information about a position of a user's eye, and the pixel intensity values are modified based on the eye tracking information. An image is displayed on the plurality of displays based on the determined pixel intensity values. The plurality of displays may be within an HMD, and address vergence accommodation conflict by simulating retinal defocus blur.
