  • Patent number: 11068072
    Abstract: In a mixed reality display system, a server and a plurality of mixed reality display terminals are connected, and virtual objects are displayed. The virtual objects include a shared virtual object for which a plurality of terminals have an operation authority and a private virtual object for which only a specific terminal has an operation authority. The server has virtual object attribute information for displaying the virtual objects in each terminal, and each terminal has a motion detecting unit that detects a motion of a user for switching between the shared virtual object and the private virtual object. When a detection result by the motion detecting unit is received from the terminal, the server updates the virtual object attribute information depending on whether the virtual object is the shared virtual object or the private virtual object, and transmits data of the virtual object after the update to each terminal.

  • Publication number: 20210149029
    Abstract: An image-capturing device includes a sensor, a visible-light-pixel driver, and a non-visible-light-pixel driver. The sensor is configured to have a plurality of visible light pixels having sensitivity to visible light and a plurality of non-visible light pixels having sensitivity to non-visible light. The visible-light-pixel driver controls light exposure to the visible light pixels and a reading operation for charges generated by photoelectric conversion of the visible light pixels resulting from the light exposure. The non-visible-light-pixel driver performs the light exposure to previously-set every two or more non-visible light pixels at the time of the light exposure to the non-visible light pixels and the reading operation, sums the charges generated by the photoelectric conversion of the two or more non-visible light pixels resulting from the light exposure, and creates the distance image on the basis of the summed charges.

  • Publication number: 20210141291
    Abstract: A lens unit capable of checking the airtightness of a seal member between an object side lens and an inner circumferential surface of a lens barrel. A part of an end portion of an air hole on the object side is opened radially inward from the inner circumferential surface of the lens barrel, and at least part of the end portion of the air hole on the image side is opened. When the image side lens is in close contact with the lens installation surface of the flange portion, the air fills the lens barrel through the air hole. The seal member provided between the object side lens and the inner circumferential surface of the lens barrel is damaged or it's not attached to a predetermined position from the beginning, it's still possible to measure air leakages, thus rendering it possible to exactly check the airtightness of the seal member.
