A head-up display device includes: a reflection member disposed in front of a driver who drives a vehicle; a projection unit configured to project light toward the reflection member and display a virtual image in a region superimposed on a superimposing display target when viewed by the driver; and an imaging unit configured to take an image of a region in front of the vehicle to generate a front image that is an image of the region in front of the vehicle. The projection unit adjusts a luminance distribution of a virtual image in accordance with a luminance distribution of a region of the superimposing display target in the front image.

A laser-based warning system for a vehicle, the system including: a laser device located on an inner face of a ceiling of a vehicle frame; and a controller configured to generate an emergency message and send the message to the laser device, wherein the laser device is configured to receive the emergency message and to shape a laser based on the message to irradiate the laser-based message onto a front, left, right, rear glasses of the vehicle selectively.

A method for operating a reflection display system for displaying a display image for a vehicle occupant of a motor vehicle by reflection of the display image on a reflection surface, in particular on a front windscreen, includes outputting a sequence of measurement display images with different patterns with different lighting intensities in some regions; detecting a brightness signal by an ambient brightness sensor while each measurement display image of the sequence is being displayed in order to obtain a brightness profile of the brightness signals; evaluating the profile of the brightness signals with respect to a predefined reference brightness profile which specifies brightness signals when the display surface is uncovered, for the sequence of measurement display images with constant ambient brightness; and signaling the presence of a foreign object on the display surface depending on the result of the evaluation.

In a vehicle-use image display system and a method therefor capable of displaying images, a driver can recognize, more appropriately and instantaneously, an object in eyesight through a front windshield during driving a vehicle even in environment with poor visibility. A vehicle-use image display system using a driving support system in combination with an ACC system or a travel environment recognition system includes a display device that uses a front windshield for screen displaying, and a display controller for controlling image displaying, by the display device, of an object detected in front of the own vehicle. The display controller causes a marking image or a displaying outline having a shape corresponding to an outline of the object to be displayed as being superimposed to the object actually existing in actual scenery viewed through the front windshield. A displaying property of the marking image may be adjusted and varied.

An information display device mountable on a vehicle, a vehicle apparatus, and a method for displaying an image to a driver of a vehicle. The information display device includes a controller configured to display information including information display related to a route along which the vehicle is to travel as a virtual image in a display area, and alter properties and characteristics of the information display being displayed in the display area. Alternatively, the controller is configured to display information including information display related to a route along which the vehicle is to travel as a virtual image in a display area, and switch between showing and hiding the information display being displayed in the display area. The vehicle apparatus includes the information display device and a vehicle on which the information display device is mounted.

An electro-optic assembly includes a first partially reflective, partially transmissive substrate defining a first surface and a second surface. A second partially reflective, partially transmissive substrate defines a third surface and a fourth surface. A space is defined between a first substrate and a second substrate. A seal is disposed about a perimeter of the first and second substrates. An electro-optic material is disposed between the second surface of the first substrate and the third surface of the second substrate. The electro-optic assembly is operable to change at least one of a reflectance state and a transmittance state in either a discrete or continuous manner. A transparent electrode coating is disposed between the second surface and the third surface. The transparent electrode coating includes an insulator layer, metal layer, and insulator layer (IMI) structure. The reflectance off of the transparent electrode coating is less than about 2%.
