An ECU as a vehicle device includes an image generation unit that generates an image in a predetermined reference coordinate system, a viewpoint position identification unit that identifies a viewpoint position of a driver; a superimposed position identification unit that identifies a display position at which the image is displayed within an eyesight of the driver; an image conversion unit that generates a converted image obtained by converting the image into a coordinate system having the viewpoint position of the driver as a reference point; and a notification unit that displays a display image falling within the converted image so as to be superimposed on the eyesight of the driver with the projection device.

Systems, devices, and methods are disclosed in which one or more light sources, a detector, a processor and a controller are configured such that light from the one or more light sources can provide illumination or projections that can reduce accidents while the vehicle is in motion and when parked and may also provide information and illumination to the driver and vehicle occupants when entering or exiting the vehicle. These systems may, for example, provide spot illumination to moving objects or pedestrians on the road surface, with the spot illumination following the moving object. Alternatively or in addition these systems may project images on the ground, for example to communicate information to occupants of the vehicle, to occupants of another vehicle, or to pedestrians.

A system in a vehicle comprising one or more sensors configured to obtain cognitive-load data indicating a cognitive load of an occupant of the vehicle, a controller in communication with the one or more sensors, wherein the controller is configured to determine a cognitive load of the occupant utilizing at least the cognitive-load data in response to an initiation of a video conference session, and output on a vehicle display a first user interface in connection with the video conference session when the cognitive load exceeds a threshold and a second user interface in connection with the video conference session when the cognitive load is below a threshold, wherein the second user interface includes video of the video conference session and the first user interface excludes video of the video conference session.

A head-up display apparatus adapted to project an image light beam onto a target element is provided. The head-up display apparatus includes a display unit, a diffusion device, and an optical system. The display unit is adapted to provide the image light beam comprising a first light beam and a second light beam. The diffusion device includes a first diffusion region and a second diffusion region, and optical structures of the first and the second diffusion regions are different. The first diffusion region and the optical system are located on a transmission path of the first light beam and guide the first light beam to the target element to form a first image. The second diffusion region and the optical system are located on a transmission path of the second light beam and guide the second light beam to the target element to form a second image.

A device includes a microprocessor and a computer readable medium coupled to the microprocessor. The computer readable medium includes instructions stored thereon that cause the microprocessor to receive output from at least one sensor monitoring an interior space of a vehicle and determine, based on the received output, a condition of an occupant in the interior space of the vehicle. The instructions cause the microprocessor to determine, based on the determined condition of the occupant, to alter a first presentation of information displayed to a display device of the vehicle to a second presentation of the information displayed to the display device. The instructions case the microprocessor to render the second presentation of the information to the display device of the vehicle to replace the first presentation of the information displayed to the display device of the vehicle.

A vehicle display device includes: one or more display devices configured to: display a main image on a vehicle cabin interior side of a front windshield in a non-occupant-driven state; and display a sub image corresponding to a content of the main image on an instrument panel in the non-occupant-driven state.

An information providing apparatus includes one or more processors; and a memory storing instructions, which when executed by the processors, cause the processors to acquire, by a display unit, information on a predetermined position outside a moving body to display an information providing image for providing information associated with the predetermined position as a virtual image; and control the display unit to change a display position of the information providing image according to movement of the moving body. The display position of the information providing image is changed such that a deviation amount between the predetermined position and a position at which a straight line passing through a reference point within the moving body and the display position of the information providing image reaches a surface on which the moving body is moving decreases as a distance between the moving body and the predetermined position decreases.

A light guide unit has a cold mirror unit to guide display light toward a projection window. In an XYZ color system, a wavelength region between a wavelength at which a value of a color matching function Z is maximum and a wavelength at which a value of the color matching function Y is maximum is a first wavelength region, and a wavelength region between a wavelength at which a value of a color matching function Y is maximum and a wavelength at which a value of a color matching function X is maximum is a second wavelength region. A minimum reflectance of the cold mirror unit to the display light takes a minimum value among reflectances of the respective wavelengths in a corresponding wavelength region. The minimum reflectance in the second wavelength region is larger than the minimum reflectance in the first wavelength region.

The present disclosure relates to a display control apparatus (1) for dynamically controlling the display of information in a vehicle (3). The display control apparatus (1) comprises a controller (12) having at least one electronic processor (13). The at least one electronic processor (13) is configured to control first and second displays (4, 5). In dependence on a determined gaze direction of the vehicle driver, the at least one electronic processor (13) controls a switching module (16) to cause a first information data set (INF1) displayed on said first display (4) to be displayed on said second display (5). The present disclosure also relates to a method of controlling the display of information in a vehicle (3).

A head-up display device includes: an image formation unit which emits light including image information; and a projection optical system including an ocular optical system which displays a virtual image by reflecting the light emitted from the image formation unit. The ocular optical system includes spherical lenses, a free-form curved surface lens, a reflection mirror, and a free-form curved surface mirror, and is configured by arranging, in a space on the side of the ocular optical system of a plane conjugate with the virtual image plane with respect to the ocular optical system, a first small lens system which achieves first focus position movement and on which separated light from the image formation unit is made to be incident, and a second small lens system which achieves second focus position movement and on which separated light from the image formation unit is made to be incident.
