A vehicle user interface apparatus for a vehicle including a light emitting unit configured to emit light; a touch sensor configured to sense a touch; a processor configured to control the light emitting unit to emit the light in response to an event, activate the touch sensor when the light is emitted, and provide a signal to control a vehicle device corresponding to a touch input received through the activated touch sensor; and a cover covering the light emitting unit, the touch sensor, and the processor, the cover configured to transmit the light into a passenger compartment with a specific shape when the light is emitted.

A vehicle-mounted stereo camera device that achieves high-precision distance detection is provided. The provided vehicle-mounted stereo camera device includes a left camera and right camera disposed on a vehicle to cause a visual field of the left camera and a visual field of the right camera to overlap each other, a stereo processor that calculates a distance to a body outside the vehicle based on images captured by the left camera and right camera and on positions of the left camera and right camera on the vehicle, and sensors disposed near the left camera and right camera for detecting displacement amounts of the left camera and right camera. The stereo processor changes a cutout positions in the images captured by the left camera and right camera based on the displacement amounts.

This display system includes: a projection device including a phase-modulation-type spatial light modulator element, a light source radiating light to a display part of the element, and a control circuit controlling the element and the light source; and projecting reflection light of the part of the element; and a reflecting mirror reflecting projection light of the device. The control circuit displays, on the part of the element, a first pattern and a second pattern associated with display information having different definition degrees. The reflecting mirror includes a first reflection region causing reflection light of a portion where the first pattern is displayed to enter, and reflecting the light toward a first display region, and a second reflection region causing reflection light of a portion where the second pattern is displayed to enter, and reflecting the light toward a second display region.

A lighting apparatus for a motor vehicle has a lighting module. The lighting module includes a laser light source for generating laser light. The laser light source has one or more laser diodes. The lighting module also includes an optical device on which the laser light is incident and which is designed to generate a defined symbol in the surroundings of the motor vehicle. The optical apparatus includes one or more holographically optical elements which are substantially non-absorbent to the laser light and which are designed to produce an interference of the laser light by phase modulation thereof in order to generate the defined symbol.

A scanning-type display device includes: a light source which emits projection-display laser light; an optical scanning unit which uses the laser light emitted from the light source in scanning; and a light diffusion unit which includes a plurality of light diffusion channels arranged in two dimensions and diffuses the laser light used in scanning by the optical scanning unit. The light diffusion unit is configured so that an angle formed by optical paths extending to an eye of an observer through a pair of adjacent light diffusion channels arbitrarily selected from among the plurality of light diffusion channels becomes equal to or larger than an angle set on the basis of a resolution angle of the eye.

A head-up display system includes an image generating apparatus configured to emit light having a first polarization and including image information; a polarization beam splitter provided on an optical path of the light having the first polarization and configured to transmit the light having the first polarization; a wave plate configured to transmit the light transmitted through the polarization beam splitter while changing a phase of the light; and a mirror configured to reflect the light sequentially transmitted through the polarization beam splitter and the wave plate back to the polarization beam splitter through the wave plate. The polarization beam splitter may reflect light having a second polarization that is different from the first polarization and obtained by transmitting the light reflected by the mirror back through the wave plate.

A method and an illumination arrangement for generating image effects in the interior of a motor vehicle or also outside the motor vehicle. To use existing installation space as efficiently as possible, light is radiated, in the form of at least a first optical reference wave field, onto a irradiation surface that is arranged laterally on an optical image storage device. In the optical image storage, which contains a holographic layer or a diffractive optical layer, the optical reference wave field is transformed into at least a first image wave field and is emitted on an emission side, at a first angular offset with respect to the irradiation surface.

A head up display arrangement for a motor vehicle includes a head up display module having a picture generation unit emitting a light field. A plurality of linear polarizers are arranged in a stack. A first of the linear polarizers receives the light field from the picture generation unit. A last of the linear polarizers emits the light field. A windshield reflects the light field from the last linear polarizer such that the reflected light field is visible to a human driver of the motor vehicle as a virtual image.
