The present invention relates to a head-up display for a vehicle configured to change display positions of a plurality of virtual images displayed through a windshield of the vehicle or the like to implement augmented reality and a control method thereof, and a head-up display for a vehicle according to an embodiment of the present disclosure may include a mirror unit comprising a first mirror for reflecting first and second image lights toward a windshield of the vehicle; a display layer located at the windshield of the vehicle to display a first virtual image corresponding to the first image light in a first region, and display a second virtual image corresponding to the second image light in a second region; and a controller configured to change an inclination of the first mirror to change a display position of the first and the second virtual image.

Intelligent application of reserves to transactions are described. In an example, server(s) associated with a payment processing service receive, from a point-of-sale (POS) device operated by a merchant, transaction data associated with a payment transaction between the merchant and a customer. Based on a predictive model, the server(s) can determine a level of risk associated with the merchant and/or the payment transaction and can determine a portion of the transaction to withhold from a settlement amount of the payment transaction based at least in part on the level of risk. The portion can be deposited into a reserves account associated with the payment processing service to satisfy costs associated with chargeback requests.

An imaging apparatus for conveying a virtual image including a waveguide having first and second surfaces. An in-coupling diffractive optic and an out-coupling diffractive optic arranged along one of the first and second surfaces, wherein the in-coupling diffractive optic is operable to direct image-bearing light beams into the waveguide for propagation by total internal reflection, and wherein the out-coupling diffractive optic is operable to direct at least a portion of the image-bearing light beams from the waveguide through the second surface toward an eyebox. An at least partially transparent outer cover located adjacent to the first surface, and a circular polarizer arranged between the waveguide and the outer cover, wherein the circular polarizer is operable to circularly polarize at least a portion of image-bearing light beams transmitted through the first surface and to prevent at least a portion of image-bearing light beams transmitted through the first surface from reentering the waveguide as a result of reflection from the outer cover.

A light field near-eye display device and a method of light field near-eye display are provided. The light field near-eye display device includes a processor, a display panel, and a lens module. The processor adjusts a preset eye box according to a vision data to obtain an adjusted eye box, and adjusts a preset image data according to the adjusted eye box to generate an adjusted image data. The display panel is coupled to the processor and emits an image beam according to the adjusted image data. The lens module includes a micro lens array and is disposed between the display panel and a pupil. The image beam is incident on the pupil via the lens module and displays a light field image.

An apparatus for displaying a three-dimensional image. The apparatus includes a light source, an intensity modulator to modulate an intensity of a given light beam, a mirror device to modulate spatially the intensity-modulated light beam at a given time instant, a first optics to collimate the spatially-modulated light beam and an image waveguide comprising an in-coupling structure to receive the collimated light beam and an out-coupling structure comprising out-coupling sites. The image waveguide directs the collimated light to the out-coupling structure which selectively redirects multiple reflections towards a segmented optical structure comprising at least two types of segments to redirect a first part of the multiple reflections to form a first type image point P1 at a first focal distance d1, d1′ and a second part of the multiple reflections to form a second type image point P2 at a second focal distance d2, d2′.

There is described a method for controlling, in a display, a virtual image of a displaying object for which displaying is controllable. The method comprises providing a curved mirrored surface opposing the displaying object to produce the virtual image. The location of an observer is determined, with respect to the curved mirrored surface. A position of the virtual image can then be determined for the observer at the location, wherein this virtual image provides at least one of parallax and a stereoscopic depth cue. The displaying object is controlled to produce the virtual image as determined.

Thin, multi-focal plane, augmented reality eyewear are disclosed. An example lens structure includes a two-layer waveguide including a first waveguide and a second waveguide. The two-layer waveguide produces a virtual object based on light from an image source. The two-layer waveguide causes the virtual object to appear at a first virtual object focal plane. The first waveguide propagates more of the light in a first wavelength range than in a second wavelength range. The second waveguide propagates more of the light in the second wavelength range than in the first wavelength range. The first wavelength range is associated with longer wavelengths than the second wavelength range. The lens structure further includes an optical lens to cause the virtual object to appear at a second virtual object focal plane associated with a shorter apparent distance from a user than the first virtual object focal plane.

An image display device includes a processor that sets a location of a virtual image plane on which a virtual image is formed according to depth information included in first image data and generates second image data obtained by correcting the first image data based on the set location of the virtual image plane; an image forming optical system including a display element configured to modulate light to form a display image according to the second image data and a light transfer unit that forms the virtual image on the virtual image plane, the virtual image corresponding to the display image formed by the display element, the light transfer unit comprising a focusing member; and a drive unit that drives the image forming optical system to adjust the location of the virtual image plane.

A head-up display includes a picture generation unit configured to emit first light for generating a first picture at a position away from a vehicle by a predetermined distance and second light for generating a second picture at a position away from the vehicle by a distance different from the predetermined distance; and a reflection unit configured to reflect the first light and the second light so that the first light and the second light are radiated to a windshield. A first optical element that reduces transmittance of light including at least visible light to be lower than transmittance of the first light is provided between the picture generation unit and the windshield at a position through which the second light passes.

An imaging system includes a light source configured to generate a light beam. The system also includes first and second light guiding optical elements having respective first and second entry portions, and configured to propagate at least respective first and second portions of the light beam by total internal reflection. The system further includes a light distributor having a light distributor entry portion, a first exit portion, and a second exit portion. The light distributor is configured to direct the first and second portions of the light beam toward the first and second entry portions, respectively. The light distributor entry portion and the first exit portion are aligned along a first axis. The light distributor entry portion and the second exit portion are aligned along a second axis different from the first axis.
