  • Patent number: 11914145
    Abstract: Disclosed in the present invention is a floating hologram system. The floating hologram system includes a diffuser configured to form a projection image using light beams transmitted from an image transmitter and diffuse the formed image, and a holographic optical element on which the image diffused from the diffuser is incident and which generates a virtual image floating at a position a predetermined distance therefrom and has a convex lens characteristic. A distance between the diffuser and the holographic optical element is determined based on a focal length of the holographic optical element and a distance from the holographic optical element to the virtual image.

  • Publication number: 20230360178
    Abstract: A system, such as for use in an automobile, is configured to process image data that includes infrared values and visible light values (e.g., data generated by a red, green, blue, infrared (RGB-IR) sensor). The system determines how to blend IR data and visible light data together to generate optimal images according to current light levels. In embodiments, the system computes a scene detection value for the image data based on a comparison between the infrared values and the visible light values. The system can then determine an amount of infrared correction, a color correction factor, a color saturation factor, etc. to apply to the image data. The system then transforms the image data based on the amount of infrared correction, the color correction factor, the color saturation factor, etc. The transformed image data includes more information for low light scenes than is traditionally available, and thus produces higher quality images in embodiments.
