A first input unit in a head-up display obtains a distance to an object. A second input unit obtains a user's eye position. An optical system projects, into the user's field of view, a virtual image of an image displayed on a display panel. A processor causes the display panel to display a parallax image. An optical element causes a first image displayed on the display panel to reach the user's first eye and a second image on the display panel to reach the user's second eye. The processor causes the display panel to display an image element in the parallax image as at least partially superimposed on the object. The processor performs first control to fix, in response to the distance to the object greater than or equal to a predetermined first distance, parallax of the image element to a value other than 0 corresponding to the first distance.

A head-up display includes a display panel, a reflective optical element, a controller, and an obtainer. The display panel displays a first image. The reflective optical element reflects image light from the first image displayed by the display panel. The controller controls a position at which the first image is displayed on the display panel. The obtainer obtains, as positional information, a position of an eye of a user. The controller changes the position at which the first image is displayed on the display panel in accordance with the positional information.

A head-up display is mountable on a movable body, and includes a first display panel, a reflective optical element, and an optical member. The first display panel displays a first image. The reflective optical element at least partially reflects image light from the first image displayed by the first display panel toward a user of the movable body. The optical member is between the display panel and the reflective optical element and is light transmissive. The display panel includes a surface facing a surface of the optical member. Each of the surface of the display panel and the surface of the optical member includes a reflection reduction layer to reduce light reflection.

A head-up display system includes a first projection module that projects a first image to display the first image in a forward direction not directly facing a user, a second projection module that projects a second image to display the second image in a forward direction directly facing the user, and a reflective optical element that reflects at least a part of the first image and at least a part of the second image.

A vehicular display control device including: memory; and a processor coupled to the memory, wherein the processor is configured to: detect when a right-side operation region provided on a right side of a steering wheel has been operated; detect when a left-side operation region provided on a left side of the steering wheel has been operated; in a case in which operation of the right-side operation region has been detected, display a right-side image corresponding to the right-side operation region in a right-side area of a display region set in front of a driving seat; and in a case in which operation of the left-side operation region has been detected, display a left-side image corresponding to the left-side operation region in a left-side area of the display region.

The present invention relates to a method for displaying augmented reality information in vehicles. In particular, the invention relates to a method for displaying an augmentation on a windshield (12) of a vehicle (10), taking into account an current viewing direction of an occupant. The method prepares (900) augmented reality information for display on the windshield (12); detects (910) the current viewing direction (R) of an occupant (F) with respect to the windshield (12); defines (930) a clearance area (A) of the windshield (12) around the current viewing direction (R); and displays (940) the prepared augmented reality information taking into account the defined clearance area (A) on the windshield (12).

A hybrid projector apparatus for a vehicle includes a heads-up display (HUD) projector disposed in a housing that includes a transparent area. The hybrid projector apparatus includes a holographic optical elements (HOE) projector supported by and at least partly exterior to the housing and is arranged to project light through the transparent area.

A head-up display apparatus includes: a display unit, which includes a display cell and a first polarizing plate with a retardation layer arranged on an output side of the display cell, the first polarizing plate with a retardation layer including a polarizer and a first retardation layer in the stated order from the display cell side, and which is configured to output projection light; at least one reflector configured to reflect the projection light; a housing, which has an opening portion, and which is configured to store the display unit and the reflector therein; a cover member configured to cover the opening portion; and a second polarizing plate with a retardation layer, which is arranged on a housing inner side of the cover member, and which includes a polarizer and a second retardation layer in the stated order from the cover member side.

The techniques of this disclosure relate to a vehicle occupancy-monitoring system. The system includes a controller circuit that receives occupant data from an occupancy-monitoring sensor of a vehicle. The controller circuit determines an occupancy status of respective seats in a cabin of the vehicle based on the occupancy-monitoring sensor. The controller circuit indicates the occupancy status of the respective seats on a display located in a field of view of occupants of the vehicle. The display is integral to one of a roof light module, a door panel, or a headliner of the cabin. The system can improve passenger safety by alerting the operator and other occupants about the occupancy status of the passengers.

A method for capturing, by a host vehicle camera, an image of a leading vehicle, estimating a leading vehicle dimension and a first distance between a host vehicle and the leading vehicle in response to the image, receiving a data indicative of a traffic signal location and a traffic signal cycle state, determining a second distance between the host vehicle and the traffic signal, estimating a traffic signal view obstruction in response to the leading vehicle dimension, the first distance, and the second distance, and generating a graphical user interface indicative of the traffic signal cycle state in response to the traffic signal view obstruction.
