  • Patent number: 10540818
    Abstract: Video data of an environment may be prepared for stereoscopic presentation to a user in a virtual reality or augmented reality experience. According to one method, a plurality of locations distributed throughout a viewing volume may be designated, at which a plurality of vantages are to be positioned to facilitate viewing of the environment from proximate the locations. For each location, a plurality of images of the environment, captured from viewpoints proximate the location, may be retrieved. For each location, the images may be reprojected to a three-dimensional shape and combined to generate a combined image. The combined image may be applied to one or more surfaces of the three-dimensional shape to generate a vantage. The vantages may be stored such that the vantages can be used to generate stereoscopic viewpoint video of the scene, as viewed from at least two virtual viewpoints corresponding to viewpoints of an actual viewer's eyes within the viewing volume.

  • Patent number: 10225545
    Abstract: This fully-automated 3D photo booth uses a single-or dual-lens camera or other depth sensors. Depth algorithms process the pictures taken, which can be inserted into themed templates. A novel method of coarse segmentation separates the foreground and background. The photo booth dispenses an interlaced print and snap-in photo frame, or gives the option of viewing on a mobile device or sending via email or social media. On a mobile device, the 3D viewing is with a snap-on or adhesive optical overlay if available, using novel lenticules that solve Moiré artifacts. In the absence of an optical overlay, tilt sensors are used to move the viewpoint of the 3D scene model, to look around objects in the foreground, the same as if real objects were being tilted back and forth.

  • Patent number: 9459524
    Abstract: The embodiment of the present invention provides a mask plate and a method of patterning using the mask plate, the mask plate comprising a light shielding area and an opening area, the edge of the opening area being in a concave-convex shape. The embodiment of the present invention, by setting the edge of the opening area of the mask plate in a concave-convex shape, can improve linearity of the matrix edge formed after the processes of coating, exposing, developing, roasting of the photoresist, so as to prevent the problem of generating a jagged or a wavy shape at the matrix edge of a color filter in a color film substrate, thereby improving uniformity of color display of a liquid crystal display. The effect is particularly significant for a product using a negative photoresist or with a relatively thin line width in the formed matrix.

  • Patent number: 9106925
    Abstract: Compression of a video by segmentation, transformation, transform encoding, difference encoding, and muxing. The segmentation looks at energies of the frames, in order to find three different things: black frames which have energy less than the specified amount, consecutive frames which have energy difference is less than the specified amount, and changes in scene which have energy difference is more than a specified amount. If there is little or no energy or energy difference, then the frame is replaced by an indication rather than information about the frame itself; either an indication of a black frames or an indication of no change between two adjacent frames. If there is much energy, then this is taken as the beginning of a new scene, and used as an area to change group of frames.
