An image display module, a movable object, and a concave mirror improve the quality of a stereoscopic image provided to a user. An image display module includes a display that displays a planar image and a parallax image projected to a first eye and a second eye of a user through an optical system, a barrier that causes parallax between the first eye and the second eye by defining a traveling direction of image light for the parallax image, and a concave mirror that includes a part of the optical system. The parallax image projected through the optical system has less distortion than the planar image projected through the optical system.

A light source unit (60) used for a vehicular head-up display according to the present invention is provided with: a tubular multi-reflection member (61) which connects an entrance plane (63) and an exit plane (64) and which has a reflecting plane (66) provided on an inner surface thereof; and a substrate (62) which is disposed so as to face the entrance plane (63) and on which a plurality of light sources (65) are mounted in a matrix configuration. The ratio Ra=AB between the number A of light sources (65) disposed in a long-axis direction (X) of the entrance plane (63) and the number (B) of light sources (65) disposed in a short-axis direction (Y) of the entrance plane (63) is configured to be greater than the ratio Rb=C/D between the long-axis dimension C and the short-axis dimension D of the exit plane (64).

A display device includes a plurality of display units and a reflector. The plurality of display units emits display light representing an image to be displayed from a display screen. The reflector is disposed to face the display screen of each of the plurality of display units and reflects the display light emitted from each of the plurality of display units.

Technologies and techniques for displaying information for an occupant of a motor vehicle. The display position of a head-up display is able to be varied flexibly depending on the context. To this end, both a displacement of the X and/or Y position and a color selection adapted to the background may be implemented and be performed automatically. Information from the steering angle, speed, map data and also head tracking by the interior camera may be combined to determine the X and/or Y position. In order to achieve optimum visibility for any load case, sensor fusion from the position data and an exterior camera may take place: Content or information (24) may thus be displayed depending on the current display position, so as to be more visible. If only some of the information is on a background, only some of the color may also change.

A heads up display system of a vehicle includes a combiner screen having a first substantially transparent substrate defining a first surface and a second surface, a second substantially transparent substrate defining a third surface and a fourth surface. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic material is positioned within the cavity and a transflective layer having a multilayer polymeric film positioned on one of the first and second surfaces, and a projector for projecting light having a first polarization toward the first surface of the first substrate.

In an information display apparatus displaying information onto a vehicle, an information display apparatus capable of acquiring a lot of pieces of image information while reducing point-of-view motion of a viewer is provided. An information display apparatus displaying information onto a vehicle includes a first information display apparatus displaying image information of a virtual image by allowing a windshield glass of a vehicle to reflect light, a second information display apparatus acquiring a practical image by scanning the windshield glass with laser light using a MEMS element and a third information display apparatus using an instrument panel of the vehicle.

A convenient device control apparatus for a vehicle and a method thereof are provided. The convenient device control apparatus includes a light source that emits light at a specified frequency and an electroencephalogram (EEG) sensor that measures an EEG signal of a user. An EEG analyzer analyzes a frequency of the EEG signal measured by the EEG sensor and a controller operates a convenient device in the vehicle based on the frequency of the EEG signal analyzed by the EEG analyzer.

A main controller of an HUD is configured to: acquire road surface information of a front road surface based on a plurality of measurement points on the front road surface, which is detected by a road surface detection sensor mounted on a vehicle with the HUD and is positioned forward of a traveling direction of the vehicle; calculate, by using the road surface information, a virtual image plane position on a virtual image plane where a virtual image of a display object is displayed, which is a display position of the virtual image for displaying the virtual image along the front road surface; and calculate a display position of a display surface within an image display device, which corresponds to the virtual image plane position, so as to output, to the image display device, a control signal for displaying the display object on the display position of the display surface.

A display control device for controlling a display position of a virtual image displayed and superimposed on a foreground in a vehicle (A), includes: an information acquisition unit for acquiring state information of the vehicle and extracting attitude change information and vibration information of the vehicle from the state information; a position correction unit for correcting a displacement of the display position of the virtual image with respect to the foreground caused by the attitude change of the vehicle, based on the attitude change information; a rough road determination unit for determining whether a road is a rough road, the road on which the vehicle is traveling or scheduled to travel, based on the vibration information; and a correction suppression unit for suppressing a correction control of the display position executed by the position correction unit and continuing to display the virtual image, based on a rough road determination.

An optical system includes a light guide member and a plurality of prism pieces. The light guide member has an incident surface on which light is incident, and first and second surfaces facing each other, and the second surface is a light-emitting surface. The plurality of prism pieces are provided on the first surface and reflect the light passing through an inside of the light guide member toward the second surface. The plurality of prism pieces include two or more prism pieces having different inclination angles with respect to an incident surface depending on a position in at least a first direction along both the incident surface and the first surface. The inclination angles of two or more prism pieces are determined so that the light emitted from the second surface is directed to the outside or the inside of the first direction with respect to a reference light beam as the prism piece is positioned closer to both ends of the first surface in the first direction.
