A head up display arrangement is for a motor vehicle having a human driver. A camera is positioned and configured to capture images of an object being towed by the vehicle. A head up display module produces virtual images that are visible to the driver. The head up display module is operable in a conventional mode in which the virtual images are independent of the images captured by the camera, and in a tow mode in which the virtual images are dependent upon the images captured by the camera.

A display device includes a light projection device which projects light including an image, an optical mechanism which is capable of adjusting a distance from a predetermined position to a position where the light is formed as a virtual image, a concave mirror which reflects light toward a reflector, a concave mirror actuator which adjusts a reflection angle of the concave mirror, and a control device which controls the light projection device and the concave mirror actuator, in which the control device adjusts a projection position on a projection surface of the light projected from the light projection device having an angle formed by a horizontal surface passing through a predetermined position on an image and a segment from the predetermined position to a position where the light is formed as a virtual image so as to curb fluctuation occurring due to movement of a vehicle.

An operation input apparatus for a vehicle, comprising: a touch panel display that extends in a vehicle width direction; an instrument panel that has a flat surface that extends from a position near a lower end of the touch panel display, in a rearward direction of the vehicle; and an operation input unit that is provided in the flat surface, wherein the operation input unit includes one or more button switches, and upper surfaces of the one or more button switches are flush with the flat surface, or are located on a lower side of the vehicle relative to the flat surface.

A driver can intuitively and conveniently perform an operation for instructing a traffic lane change to a vehicle. In a driving support device 10, an image output unit 14a outputs, to a display unit 31, an image containing an own vehicle object representing an own vehicle and a plurality of traffic lanes. An operation signal input unit 14b receives an operation of a user for moving the own vehicle object in the image displayed on the display unit 31 from a first traffic lane to a second traffic lane. A command output unit 14c outputs, to an automatic driving control unit 20 that controls automatic driving, a command for instructing the change of a traveling traffic lane of the own vehicle from the first traffic lane to the second traffic lane when the operation is received.

An image display device includes a light source, a screen, an optical system, a converging lens, an optical distance correction member, and a scanning unit. The converging lens is configured to converge the light emitted from the light source onto the screen. The optical distance correction member is disposed between the converging lens and the screen. The scanning unit scans the screen with the light from the light source. The screen is disposed so as to be inclined with respect to a plane perpendicular to an optical axis of the converging lens so that a viewing distance of the virtual image gradually varies. The optical distance correction member adjusts an optical distance of light transmitting through the optical distance correction member so that a distance between the screen and a focusing position of the light is made substantially identical over an entire image display region in the screen.

A light diffusion member constituting a head-up display device includes multiple micro-lenses and has a curved base surface. The edge angle is larger than the base surface angle change amount. The edge angle is an angle formed by one of tangent lines of two micro-lenses and the other of the tangent lines passing through a boundary between two adjacent micro-lenses on a cross section orthogonal to the base surface. A reference line has a constant direction on the cross section, and a normal line passes at an arbitrary position on the base surface. The maximum value is .sub.max and the minimum value is .sub.min among angles between the normal line and the reference line. The base surface angle change amount is the absolute value of the difference between .sub.max and .sub.min.

A multi-eyebox head-up display device and a multilayer combiner are disclosed. The device comprises a projector generates a projected image to a reflector. The reflector generates a reflected image to a multilayer combiner. The multilayer combiner includes at least two superimposed imaging plates, and the semi-reflective surfaces of the superimposed imaging plates are tilted to each other. While the reflected image is projected to the semi-reflective surface of the topmost superimposed imaging plate, the semi-reflective surface of the topmost superimposed imaging plate generates a virtual image. Simultaneously, the reflected image penetrates through the topmost superimposed imaging plate and reaches the lower superimposed imaging plate, and the semi-reflective surface of the lower superimposed imaging plate reflects the light to generate another virtual image. The present invention enables the driver to view the vehicular information at different viewing angles.

A display system for a vehicle includes an interior camera disposed in an interior cabin of a vehicle and having a field of view interior of the vehicle that encompasses an area at or near a user input for an accessory, with the user input being accessible by a driver of the vehicle when the driver is normally operating the vehicle. A display device is viewable by the driver when the driver is normally operating the vehicle. The display device is operable to display images derived from image data captured by said interior camera. The display device displays images depicting the driver's hand as the driver's hand approaches the user input for the accessory for actuating the user input to adjust or control the accessory.

A display apparatus (500) for displaying a virtual image (VIMG1) comprises: an optical engine (ENG1) to form input light (IN1), which represents an input image (IMG0), an expander device (EPE1) to form light beams (B3.sub.P0,R,B3.sub.P1,R) of output light (OUT1) by expanding light beams (B0.sub.P0,R,B0.sub.P1,R) of the input light (IN1), the expander device (EPE1) comprising: a waveguide plate (SUB1), a diffractive in-coupling element (DOE1) to form first guided light (B1a) and second guided light (B1b) by coupling input light (IN1) into the waveguide plate (SUB1), wherein the display apparatus (500) comprises a base (BASE1) and an actuating mechanism (MOTOR1) to cause rotary motion of the expander device (500) with respect to the base (BASE1), wherein an angle (1) between an optical axis (AX0) of the optical engine (ENG1) and the axis (AX1) of rotation of the expander device (500) is in the range of 10 to 45.

An information display apparatus and a spatial sensing apparatus for the information display apparatus are provided, the information display apparatus enabling the selection/change of the lot of display images in small point-of-view motion so that an interactive function for a driver is achieved. An information display apparatus displaying information onto a vehicle includes: an information display apparatus displaying image information onto an image display region on a forward part of a driver seat of the vehicle; and a spatial sensing means detecting positional information of instruction made by a driver in a spatial region between the driver seat and the displayed image display region, and the information display apparatus includes a means displaying the instruction made by the driver onto the image display region on the forward part in response to the positional information of the instruction made by the driver, detected by the spatial sensing means.
