  • Patent number: 10437060
    Abstract: [Object] To provide an image display system that displays an image with a wide field of view while reducing VR sickness. [Solution] When a field of view FOVO of an original image provided by an image output device (200) is greater than a field of view FOVD of an image viewed by a user wearing an image display device (300), the image output device (200) cuts out a region with the field of view FOVD from the original image for delivery to the image display device (300). Also, when the field of view FOVO of the image viewed by the user wearing the image display device (300) is equal to or greater than the field of view FOVD of the original image provided by the image output device (200), the image output device (200) delivers the original image as-is to the image display device (300).

  • 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.
