  • Patent number: 10330935
    Abstract: A Predictive, Foveated Virtual Reality System may capture views of the world around a user using multiple resolutions. The Predictive, Foveated Virtual Reality System may include one or more cameras configured to capture lower resolution image data for a peripheral field of view while capturing higher resolution image data for a narrow field of view corresponding to a user's line of sight. Additionally, the Predictive, Foveated Virtual Reality System may also include one or more sensors or other mechanisms, such as gaze tracking modules or accelerometers, to detect or track motion. A Predictive, Foveated Virtual Reality System may also predict, based on a user's head and eye motion, the user's future line of sight and may capture image data corresponding to a predicted line of sight. When the user subsequently looks in that direction the system may display the previously captured (and augmented) view.

  • Patent number: 8529075
    Abstract: An antireflection structure having a high antireflection effect is provided. An antireflection structure (50) reduces reflection of light having a wavelength equal to or larger than a predetermined wavelength, and absorbs the light whose reflection is reduced. The antireflection structure (50) includes a base structure portion (7) which is configured to have a plurality of structural units (70) arranged on a reference plane, and each having a tilted surface (71) so that an angle between the first side surface (71) and a reference plane (51) is a predetermined angle, and a plurality of fine concave/convex portions (8, 8, . . . ) which are formed on a surface of the base structure portion (7), and arranged within a cycle equal to or smaller than the predetermined wavelength.

  • Patent number: 8459808
    Abstract: An exemplary light blocking plate includes a flat plate-like light pervious member, and a blocking and shielding layer formed on the light pervious member. The blocking and shielding layer includes a top surface facing away from the light pervious member, a bottom surface facing the light pervious member, and a through hole extending from the top surface to the bottom surface. The blocking and shielding layer includes an electromagnetic shielding layer having a first part of the top surface, and a light blocking layer. The light blocking layer includes a first portion having the bottom surface, and a second portion having a second part of the top surface, and extending from the first portion to the second part of the top surface. The electromagnetic shielding layer surrounds the second portion of the light blocking layer. The second portion of the light blocking layer surrounds the through hole.

  • Patent number: 8421037
    Abstract: A variety of methods and systems are described that relate to reducing optical noise. In at least one embodiment, the method includes, emitting a first light having a selected wavelength from a light source, receiving a reflected first light onto a phosphor-based layer positioned inside a receiver, the reflected first light being at least some of the emitted first light that has been reflected by an object positioned outside of a desired target location. The method further includes, shifting the wavelength of the received reflected first light due to an interaction between the received reflected first light and the phosphor-based layer, and passing the received reflected first light with respect to which the wavelength has been shifted through a light detector without detection.
