  • Patent number: 10310595
    Abstract: Provided is an image display device configured to display a free viewpoint image that tracks a movement of observer's head and trunk. The line-of-sight direction and trunk orientation of the user are individually oriented in a free viewpoint space displayed on a display device 500 based on posture information of the user's head and trunk, which are respectively obtained from a head motion tracking device 200 and a trunk motion tracking device 300. A behavior that is natural in real space can be represented by moving a line of sight to a front direction of the trunk on a space in a state where the line of sight does not match the front direction of the trunk. An unnatural UI that goes straight to the line-of-sight direction is prevented regardless of orientation of the trunk.

  • Publication number: 20190164558
    Abstract: A method, system, and computer program product for processing an encoded audio signal is described. In one exemplary embodiment, the system receives an encoded low-frequency range signal and encoded energy information used to frequency shift the encoded low-frequency range signal. The low-frequency range signal is decoded and an energy depression of the decoded signal is smoothed. The smoothed low-frequency range signal is frequency shifted to generate a high-frequency range signal. The low-frequency range signal and high-frequency range signal are then combined and outputted.

  • Publication number: 20190149935
    Abstract: The present technology relates to a sound processing apparatus and method, and a program for enabling more stable localization of a sound image. A virtual speaker is assumed to exist on the lower side among the sides of a tetragon having its corners formed with four speakers surrounding a target sound image position on a spherical plane. Three-dimensional VBAP is performed with respect to the virtual speaker and the two speakers located at the upper right and the upper left, to calculate gains of the two speakers at the upper right and the upper left and the virtual speaker, the gains being to be used for fixing a sound image at the target sound image position. Further, two-dimensional VBAP is performed with respect to the lower right and lower left speakers, to calculate gains of the lower right and lower left speakers, the gains being to be used for fixing a sound image at the position of the virtual speaker.

  • Patent number: 10235255
    Abstract: An information processing system includes first to third information processing apparatuses. The first information processing apparatus has a first memory with a cache region and outputs a first power failure signal on detecting a power failure. The second information processing apparatus includes a second memory with a mirror cache region that stores mirror data for the cache region and outputs a second power failure signal on detecting a power failure. The third information processing apparatus monitors the first and second information processing apparatuses and, when both apparatuses have stopped operating, determines whether there is a power failure at the first and second information processing apparatuses based on the first and second power failure signals. When there is no power failure at either apparatus, the first and second information processing apparatuses are restarted in a state where data of the first and second memories is held.
