  • Publication number: 20240142796
    Abstract: A more favorable air floating video display apparatus is provided. This technique contributes to the Sustainable Development Goals that are “the third goal: Good Health and Well-being (for all people)”, “the ninth goal: Industry, Innovation and Infrastructure” and “the eleventh goal: Sustainable Cities and Communities”. The air floating video display apparatus includes: a video display; and a retro-transmitting plate transmitting video light emitted from the video display to form an air floating video, a light path length of video light having been emitted from a display surface of the video display through the retro-transmitting plate to a position of the air floating video changes depending on a position on the display surface of the video display from which the video light is emitted, and the video display is configured to change a light emission amount per unit area to depend on the light path length.

  • Patent number: 11698176
    Abstract: In an illumination device, an incidence angle of a laser beam, which is scanned by a laser beam scanning mechanism, with respect to a wavelength conversion member is set to an angle where the laser beam does not directly enter a projection lens when the wavelength conversion member is damaged, chipped or fallen off, and a laser light source and the laser beam scanning mechanism are located at a position corresponding to at least one of an upper side and a lower side of a light distribution pattern with respect to the wavelength conversion member, and are disposed to be deviated to either one of one side corresponding to a left side of the light distribution pattern and other side corresponding to a right side of the light distribution pattern.

  • Patent number: 11181743
    Abstract: In relation to a HUD apparatus having an AR function, the shift between an object and a virtual image (AR image) is reduced. The HUD apparatus extracts a predetermined object based on an image taken by an external camera, acquires object information including an object position in space, viewpoint position information of a driver and the amount of movement of the viewpoint position in space based on an image taken by an internal camera, and information including a position of a virtual image region in space. The HUD apparatus generates the image to be superimposed on the object, and corrects a display position of the image in the virtual image region including at least a position in a horizontal direction, and performs conversion processing at the time of the correction so that a virtual image region is set as a display position of the image after correction.

  • Patent number: 9769448
    Abstract: An interface is realized that can prevent video signals from being copied easily and which uses a luminance/color difference signal transmission scheme with an excellent harmony with a television circuit. In a video transmission using a digital interface, colorimetry information for defining the conversion from the luminance/color difference signal into a primary color signal and video aspect ratio information are transmitted along with the luminance/color difference type video signal. This allows reproduction of video with high quality and high resolution and also realizes a copyright protection which allows only the users authorized by key information to use the content of the video. With this transmission scheme, it is possible to provide a transmitting apparatus, a receiving apparatus and an interface which highly harmonize with a rationalized television-based circuit.
