Systems and methods are provided to determine glare information. An optical filter is configured to attenuate visible light and pass near-infrared light and an image sensor is configured to detect light reflected by a surface after the reflected light passes through the optical filter. The image sensor is further configured to generate image data comprising a detected near-infrared portion of the light reflected by the surface. Processing circuitry is configured to receive the image data from the image sensor and determine near-infrared glare information based on the received image. The near-infrared glare information can be used to adjust display parameter associated with the surface or characterize near-infrared glare properties of the surface.

Embodiments are disclosed for display configurations for providing an augmented reality heads up display. In one example, a method of operating a display system includes adjusting an output of image light from a display to pass through an optical element positioned between the display and at least one micro lens array, including impinging light upon a transparent plane to generate a three-dimensional image on a continuous plane that is based on a user focal point determined by an eye-tracking module.

A window tinting system for vehicles is disclosed. The system includes a tinted glass with adjustable tint levels, controlled automatically or manually. The automatic adjustment is facilitated by a light sensor detecting sunlight intensity and transmitting data to a tint control module, which adjusts the tint level for optimal protection. A control knob disposed on the vehicle's dashboard is linked to the tint control module through control circuitry and can be turned to manually adjust tint. Additionally, a mobile application enables remote control of the tint level. The tinted glass features an outer photochromic layer that darkens in response to UV light and an inner electrochromic layer controlled by the tint control module.

A HUD 10 is configured to be able to display a plurality of virtual images at different distances. The HUD 10 includes an image generation unit 12 and a shielding member 14. The image generation unit 12 generates a first image for forming a first virtual image and a second image for forming a second virtual image to be displayed nearer than the first virtual image. The shielding member 14 can reduce an amount of external light incident on the image generation unit 12. The shielding member 14 is movable between a position through which first light constituting the first image emitted from the image generation unit 12 passes and a position through which the first light does not pass.

Provided is an interlayer film for laminated glass capable of enhancing the sound insulating property of the laminated glass. An interlayer film for laminated glass according to the present invention is an interlayer film, for laminated glass, having a two or more-layer structure, the interlayer film includes one end and the other end being on an opposite side of the one end and having a thickness larger than a thickness of the one end, at least one layer having a glass transition temperature of less than 15 C., and a region where a value of Y/X is 0.12 or more when the interlayer film has a thickness of X m and a total thickness of the at least one layer having a glass transition temperature of less than 15 C. is denoted by Y m, and the interlayer film has an average thickness of each surface layer, in a region from a position of 100 mm to a position of 400 mm from the one end toward the other end, of less than 300 m.

A device for minimizing the effects of glare of a driver of a vehicle is proposed. The device comprises a circuit configured to determine a glare intensity of the glare of the driver of the vehicle. The circuit is further configured to activate an in-vehicle safety function to increase driving safety in the presence of glare if the glare intensity exceeds a threshold.

A method for displaying a rearward image of a vehicle includes varying reflectivity of an electro-optic layer for incident light to transmit a portion of the incident light and to reflect another portion of the incident light; displaying on a display at least the portion of the rearward image; and switching the electro-optic layer between a first posture and a second posture. When the electro-optic layer is in the first posture, at least the portion of the rearward image is displayed, and when in the second posture, the reflectivity of the electro-optic layer for the incident light varies between at least two values based on at least one of a first illuminance or a second illuminance. The first illuminance indicates brightness around the vehicle and the second illuminance indicates intensity of light emitted on a front surface of the electro-optic layer.

An information display apparatus capable of reducing the viewpoint movement of a driver and achieving safer driving in consideration of the relationship between the traveling speed and the stopping distance of a vehicle is provided. The information display apparatus is configured to display image information in a transportation and comprises a HUD apparatus disposed between a windshield of the transportation and an instrument panel of the transportation. The HUD apparatus detects a viewpoint position of a driver; and displays a virtual image of the image information in front of the transportation by reflecting light emitted from the HUD apparatus to display the image information by the windshield. The HUD apparatus is configured to set a display position of the virtual image in accordance with movement of the viewpoint position of the driver who is driving the transportation.

A display control method for a vehicle-mounted display device includes a housing, an electro-optic layer configured to vary reflectivity of incident light, a display provided between the electro-optic layer and part of the housing, a sensor to detect intensity of light emitted on the display device, and an operation lever provided on the housing that switches the electro-optic layer between two postures. The display control method includes varying a reflectivity of the electro-optic layer within a predetermined range based on intensity of light emitted on the display device, and when the electro-optic layer is in a first posture, the predetermined range is between a first and second reflectivity. When the electro-optic layer is in a second posture, displaying a backward image on a display screen, and when the electro-optic layer is in the second posture, restricting the varying of the reflectivity within the predetermined range.

Embodiments disclosed herein relate to a heads-up display visor for a vehicle, such as an automobile, to provide driver assistance information to the driver. Features include a display screen that is sized and positioned relative to the driver's conventional sun visor, so as to eliminate the need to project images onto the windshield and/or to have a projector located on the vehicle dashboard. In certain embodiments, the heads-up display visor is portable, and is affixed to the driver's conventional sun visor by a clip, thereby allowing a driver to move the device from one vehicle to another.
