Man-machine interface for motor vehicle comprising a display screen (6) and a control means on which the user of the vehicle can act in order to alter a parameter of the vehicle, characterized in that it also comprises displaying means (16) and a laser projector (14), the displaying means being designed to receive an image from the laser projector and to display it on the display screen.

Disclosed herein are devices, methods and systems for producing hologram-based indicia for a vehicle dashboard/cockpit. By employing the aspects disclosed herein, indicia (electronically coupled to the vehicle's microprocessor), is lighted and projected in a three-dimensional virtual manner. The aspects disclosed herein may be embedded in various portions in the vehicle and thus, not consume extra space or area required to create virtual images through other techniques.

A vehicle display device includes: a display; a vehicle information image generator; an external image obtaining device; a display controller that displays the vehicle information image and the external image on the display; and an external image display determination device that determines whether the display controller is going to display the not displayed external image. When the display controller is going to display the not displayed external image, the display controller displays the external image, which the display controller is going to display, on the display with gradually increasing brightness of the external image from the brightness that is lower by a predetermined amount than original brightness to predetermined brightness that is determined based on the original brightness.

A vehicle display device includes: a viewpoint position acquisition unit acquiring a user viewpoint position of a user seated in a driver seat of a vehicle; a forward information acquisition unit acquiring forward information of the vehicle; an image generation unit generating an image obtained by reflecting the forward information included within a prescribed area among the forward information acquired by the forward information acquisition unit; an image display unit having a display surface capable of displaying the image generated; and a projection unit projecting the image toward a vehicle's translucent member such that a virtual image is visible to the user. The image generation unit determines the position and the size of a first image element to be displayed, among image elements included in the generated image, on the display surface, according to the user viewpoint position in the vertical direction acquired by the viewpoint position acquisition unit.

Various aspects of a system and method to provide driving assistance are disclosed herein. The system comprises one or more circuits in an electronic control unit used in a vehicle configured to detect one or more actions associated with the vehicle based on one or more signals generated by one or more sensors embedded in the vehicle. The electronic control unit may be further configured to control the activation of an imaging device located on the vehicle at an opposite side of a driver of the vehicle, based on the detected one or more actions. The imaging device is operable to capture one or more images in a forward-facing direction of the vehicle.

A main controller of an HUD is configured to: acquire road surface information of a front road surface based on a plurality of measurement points on the front road surface, which is detected by a road surface detection sensor mounted on a vehicle with the HUD and is positioned forward of a traveling direction of the vehicle; calculate, by using the road surface information, a virtual image plane position on a virtual image plane where a virtual image of a display object is displayed, which is a display position of the virtual image for displaying the virtual image along the front road surface; and calculate a display position of a display surface within an image display device, which corresponds to the virtual image plane position, so as to output, to the image display device, a control signal for displaying the display object on the display position of the display surface.

A light source unit used for a vehicular head-up display includes a prism-shaped multi-reflection member and a substrate. The multi-reflection member has: an entrance surface; an emission surface; and a reflective surface connecting the entrance surface and the emission surface. The substrate faces the entrance surface and is provided with a plurality of light sources mounted in a matrix. A ratio Ra=A/B or a ratio Rc=a/b is larger than a ratio Rb=C/D, where A and B is the number of the light sources provided in a longer and shorter direction of the entrance surface, respectively, C and D is a longer and shorter dimension of the emission surface, respectively, and a and b is the sum of lengths of light-emitting surfaces of the plurality of light sources in the longer and shorter direction of the entrance surface, respectively.

A display apparatus allows a user to visually recognize a virtual image. The virtual image has luminance characteristics according to which a dependence of luminance on viewing angle changes along a certain direction.

There is provided a vehicle display device capable of simplifying a configuration for a passenger. A ring member is provided to be closer to the front side (opposite to the passenger) than a half mirror, and thus the configuration for the passenger can be further simplified than the half mirror, thereby achieving a simple appearance. The ring member is visually confirmed through the half mirror thereby to display the ring member and an image in combination like a configuration in which a decorative member is provided to be closer to the passenger than the display as conventionally.

An information display apparatus irradiates a transmissive reflection member with light for forming an image so as to make a virtual image of the image visible on the transmissive reflection member. The information display apparatus includes a memory, and a processor coupled to the memory and configured to control, upon a change in depth of a scene position at which to superimpose the virtual image, a degree of change in a part or an entirety of the virtual image to be displayed, differently from a degree of the change in depth.
