A vehicular three-dimensional head-up display includes a display device functioning as a light source; and a combiner for simultaneously reflecting light from the light source toward a driver's seat and transmitting light from the outside of a vehicle, and may include an optical configuration in which an image created by the light from the light source is displayed as a virtual image of a three-dimensional perspective laid to correspond to the ground in front of the vehicle.

An illumination unit includes a plurality of sets of illumination modules each having a light source placed at a conjugate position and a plurality of stages of condenser lenses that collect light from the light source toward a display device, a magnifying optical system being between the conjugate position and a viewing area. Each illumination module set includes an initial stage lens as a condenser lens closest to the light source and a final stage lens as a condenser lens farthest from the light source. In each illumination module set, assuming a composite focal point of a composite lens combined from all stages of condenser lenses, a gap between a principal plane of the initial stage lens and the light source is set to be equal to or less than a gap between the principal plane and the composite focal point.

A head-up display system includes a head-up display device 10 and a smart phone 30. The head-up display device 10 includes: a communication unit 12 which establishes a communication connection by requesting a communication connection to a communication unit 32 of the smart phone 30 when power is applied to the head-up display device; a display unit 11 which visually displays navigation information received through the communication unit 12; and a control unit 13 which controls the communication unit 12 and the display unit 11. The smart phone 30 includes: a communication unit 32 which establishes a communication connection in response to the communication connection request from the communication unit 12; a navigation module 31 which generates navigation information; and a control unit 33 which controls the communication unit 32 and the navigation module 31.

A vehicular display control device includes: a display control unit for controlling a display device to superimpose an image on a surrounding view of the vehicle; and a sensor operation detecting unit for detecting whether an obstacle sensor detecting an obstacle around the vehicle is in operation. When the obstacle sensor is in operation, the display control unit: transforms a detection target area, which falls in a detection range of the obstacle sensor and expands from the vehicle to a periphery along a road surface, into a detection target image represented from a viewpoint of a driver of the vehicle; and displays a transformed image to be superimposed on the surrounding view of the vehicle.

A display device is for displaying a virtual image in front of a driver of a vehicle. The display device includes a detecting unit that receives light surrounding the vehicle, and detects a brightness of the received light; a restricting unit that restricts an angle of the received light; a correcting unit that adjusts a luminance of a display image, according to the detected brightness of the light; and a displaying unit that superimposes and displays the display image on a field of vision of the driver as the virtual image, based on the adjusted luminance. The restricting unit includes two opening restricting elements arranged on a front side of the detecting unit, such that an angle 2 at which the detecting unit receives the light is restricted according to an angle 1 formed by light beams directed from the virtual image toward eyes of the driver.

Provided is a head-up display apparatus that projects a display image, which is formed on a display surface, onto a projection surface of a movable body to display a virtual image viewable from a cabin of the movable body. The head-up display apparatus includes a display with pixels arranged along the display surface, a light source, and a diffusion plate for diffusing the light coming from the light source and emits the diffused light toward the display. The diffusion plate has through-holes in a thickness direction. In a specific direction on the display surface, an inner dimension of the through-hole is smaller than a pixel pitch of the pixels.

A reflection display system for displaying a display image for a vehicle occupant of a motor vehicle by reflecting the display image on a windshield is provided. The system includes a display unit which is designed to display the display image on a display surface, a detection sensor system for detecting the displayed display image on the display surface, and a control unit which is designed to actuate the display unit for displaying purposes, ascertain detection information on the basis of the detected displayed display image, ascertain the presence of a foreign object on the display surface of the display unit on the basis of the displayed display image and on the basis of the detection information, and signal a disruption of the display if the presence of a foreign object on the display surface of the display unit has been ascertained.

A reflection display system for displaying a display image for a vehicle occupant of a motor vehicle by reflecting the display image on a windshield is provided. The system includes a display unit which is designed to display the display image on a display surface, a detection sensor system for detecting the displayed display image on the display surface, and a control unit which is designed to actuate the display unit for displaying purposes, ascertain detection information on the basis of the detected displayed display image, ascertain the presence of a foreign object on the display surface of the display unit on the basis of the displayed display image and on the basis of the detection information, and signal a disruption of the display if the presence of a foreign object on the display surface of the display unit has been ascertained.

Provided is a vehicle display device that can improve visibility without providing a feeling of strangeness to a passenger. A vehicle display device includes a display unit provided in an inner side of an instrument panel and which projects a display image, a transparent cover that transmits the display image projected from the display unit toward a windshield, and a bezel body including an opening portion that allows the display image transmitted through the transparent cover to pass through and having an outer edge portion continuing into the windshield, and the degrees of brightness of respective reflected images of the instrument panel, the transparent cover, and the bezel body, the respective reflected images being reflected in the windshield, are made uniform, and therefore dark visual recognition of any of the reflected images is suppressed, and the feeling of strangeness provided to the passenger is relieved.
