A device for generating a virtual image with stray light suppression comprises at least one light source for producing light with a specified wavelength, a display element for producing an image, and an optical waveguide for expanding an exit pupil. An aperture mask that has holes and non-transparent regions is arranged above an upper boundary surface of the optical waveguide.

A head-up display for displaying an image as a virtual image to an observer includes a projection optical system that includes a lens element and a reflecting mirror. A light beam reaching a center of a viewpoint region of the observer and corresponding to a center of the virtual image is defined as a reference light beam. The lens element is inclined with respect to the reference light beam. The lens element includes an entrance surface on which light of the image is incident, an exit surface from which light of the image emerges, a first edge portion, and a second edge portion. The second edge portion is inclined so that, when light emitted from the image travels through the entrance surface, the second edge portion, and the exit surface in this order, light emerging from the exit surface reaches below a central portion of the reflecting mirror.

This disclosure describes systems, methods, and devices related to vehicle display enhancement. For example, a vehicle may receive data associated with a user of a vehicle, wherein the data is associated with eyewear worn by the user or information associated with a user profile. The device may identify a first object in a field of vision of the user while the user is situated in the vehicle. The device may apply first enhancement to the first object based on the data. The device may display the first enhancement on a display device of the vehicle.

A motorcycle comprising a transparent member that transparently passes light. The motorcycle further comprises a transparent electrode that is arranged on a windshield serving as the transparent member and can be manipulated by a rider (driver) of the motorcycle, a projection apparatus that projects video of a switch relating to manipulation of the motorcycle onto the transparent electrode.

A display system, a mobile object, and an optical element. The display system includes an optical device through which light diverges, a light deflector configured to scan a light emitted from a light source in a main scanning direction and a sub-scanning direction orthogonal to the main scanning direction to form an intermediate image on the optical device, and an imaging optical system configured to project diverging light diverging through the optical device to form an image. An effective diameter a of a mirror of the light deflector for the intermediate image and a ratio c of a size of an image formed by the imaging optical system to the effective diameter a satisfy a condition in an equation given below.

The mobile object includes the display system, and the reflector is a front windshield. The optical element is used for the display system.

The present invention relates to a HUD system comprising a. a light source (14) projecting polarized light towards a glazing (10), said glazing (10) comprising an outer sheet of glass (11) having a first surface (P1) and a second surface (P2), and an inner sheet of glass (12) having a first surface (P3) and a second surface (P4), b. wherein over at least a portion of at least one of the surface (P1, P2, P3, P4) of the outer (11) and/or the inner sheet of glass (12) comprises a first enhanced p-polarized reflective coating (13). According to the present invention, the said light source (14) projecting polarized light comprises a waveplate (18) to compensate glass retardation in order to have P-polarized light at the outer face (P1) of the outer glass sheet (11).

A vehicle display apparatus of the present disclosure includes a display and a reflective member. The reflective member reflects display light from the display. The display causes the display light to be incident on the reflective member as S polarized light. The reflective member is located along an incident light path of the display light from the display to a reflecting surface of a windshield of a vehicle or along a transmitted light path of transmitted light transmitted by the reflecting surface. The reflective member reflects linearly polarized incident light as circularly polarized reflected light. The vehicle display apparatus guides display light reflected at the reflective member and at the windshield to an eye box.

The head-up display apparatus includes a display-light emitting unit having a second inclination angle around the axis parallel to the vertical direction so that the first direction side thereof is closer to the user than the second direction side thereof is, and being configured to emit display light forming a rectangular image corresponding to the rectangular virtual image. The head-up display apparatus includes a reflecting mirror having a third inclination angle around the axis parallel to the vertical direction so that the first direction side thereof is closer to the user than the second direction side thereof is, and being configured to reflect the display light and emit reflected light to the virtual-image display unit.

The systems described herein facilitate providing a virtual content with an intended appearance. The virtual content can be an interactive space. The interactive space may be presented on a display of a presentation device. The display can be a transparent display. The interactive space can be superimposed over a perspective of a physical real-world environment of a user. Environmental characteristics of the physical real-world environment can alter the intended appearance of the interactive space superimposed over a perspective of a physical real-world environment. The environmental characteristics include one or more of a light intensity, color, and/or other visual features of the physical real-world environment. The appearance of the interactive space can be altered to compensate for the environmental characteristics. The appearance of the interactive space can be altered such the user can perceive the interactive space as intended by the creator of the interactive space.

A vehicle and a method for controlling the vehicle are provided. The vehicle includes a first camera configured to capture a front image of the vehicle; a head-up display configured to project an image onto a windshield of the vehicle; an input device configured to input a boundary line for setting an area in which the image is projected from the windshield; and a controller configured to determine a projection area in which the image is projected based on the inputted boundary line, to determine an interest area of the front image based on the determined projection area and a speed of the vehicle, and to display the determined interest area in the determined projection area on the head-up display.
