This head-up display system is a head-up display system for vehicles, which has a light source that emits p-polarized visible light, and laminated glass to which the p-polarized visible light is incident from the vehicle interior side, and which displays a virtual image on the vehicle exterior side of the laminated glass, wherein the laminated glass is provided with a p-polarized light reflecting member in a region where the p-polarized visible light is incident, the incident angle of the p-polarized visible light to the vehicle interior side surface of the laminated glass is at least 42 deg and at most 72 deg, the laminated glass has a visible light reflectance of the p-polarized light of at least 5% when the incident angle is 57 deg, the virtual image includes a main image observed with the highest luminance and a subsidiary image observed with a lower luminance than the main image, and the ratio of the reflectance of the subsidiary image to the reflectance of the main image is at most 30% within the entire range of the incident angle.

A light control apparatus includes a diffuser plate, a light source, a light pipe, and a light blocker. The diffuser plate includes at least one opening therein. The diffuser plate includes feature located around the opening in the diffuser plate that exposes a portion of the diffuser plate. A light source positioned proximate a second surface of the diffuser plate is optically coupled to a light pipe positioned around a portion of the opening near the second surface of diffuser plate. A light blocker is positioned near a second portion of the at least one feature. The light blocker is positioned between the light source and the second portion of the feature, the light blocker having an opening therein to allow light to pass from the light source to the diffuser plate proximate the second portion of the feature.

An information providing device is equipped with one or more displays that display notification information, a camera that acquires information of a vehicle occupant, a vehicle occupant detection unit that detects a field of view of the vehicle occupant, a display determination unit that determines whether or not there is a display that lies within the field of view, a display decision unit that makes a decision, on the basis of the determination of the display determination unit, regarding a notification display to allow the notification information to be displayed, and a notification control unit that controls the one or more displays.

A system to provide a multi-image head up display (HUD) in a vehicle includes a fixed mirror to project a far-plane image at a first distance from an occupant of the vehicle. Control of a position of display of the far-plane image is based on an eye height position of the occupant. The system also includes a rotatable mirror to project a near-plane image at a second distance, closer than the first distance, from the occupant. Control of a position of display of the near-plane image is based on a manual adjustment of a rotational angle of the rotatable mirror by the occupant. Processing circuitry automatically adjusts the position of display of the far-plane image based on inferring the eye height position of the occupant from the rotational angle of the rotatable mirror that controls the display of the near-plane image.

A light source device that supplies light in a specific polarization direction to an information display device includes a point-shaped or planar light source, an optical means for reducing the divergence angle of light from the light source, and a light guide having a reflection surface that reflects light from the light source to propagate to the information display device. The reflection surface of the light guide is arranged so as to face the information display device, and reflects specific polarized image light displayed on the information display device to be displayed on the window glass, which is an information display surface. Therefore, an information display system is realized in which the inside of the window glass can be visually recognized from the outside or the outside of the window glass can be visually recognized from the inside when image information is not displayed.

A method is described and includes identifying a reflection of an object in a reflective display element on an exterior of an autonomous vehicle (AV), wherein the object is associated with a driving event of the AV; and highlighting the reflection of the object on the at least one reflective display element.

An augmented reality (AR) display apparatus includes an outputter that outputs first radiation including visual information in a predetermined spectrum, a polarizing plate that absorbs a first s-polarized radiation from the first radiation and transmits a first p-polarized radiation and an optical layer that reflects at least a portion of the first p-polarized radiation incident on a first side of the optical layer with a wavelength corresponding to the predetermined spectrum.

A display correction system includes a first obtainer, a second obtainer, a third obtainer, a predictor, and a corrector. The first obtainer obtains travel route information on a travel route ahead of a moving body. The second obtainer obtains speed information on a speed of the moving body. The third obtainer obtains orientation information on an orientation of the moving body. The predictor predicts, based on the travel route information and the speed information, a time period during which the moving body travels through a specific section in the travel route. The corrector performs correction of a displacement of a display position of a content on a display image based on the orientation information. Based on prediction result of the predictor, the corrector executes first control when the moving body is traveling in a normal section, and executes second control when the moving body is traveling in the specific section.

An image generation device for generating an image for a head-up display includes: a first light source; a second light source disposed to be spaced apart from the first light source by a certain distance; a lens that transmits light emitted from the first light source and the second light source; and a display device that forms light that generates the image from the light transmitted through the lens. The lens is constituted by a first region that transmits first light from the first light source, and a second region that transmits second light from the second light source, and a light shield is further provided to prevent the first light from transmitting through the second region and prevent the second light from transmitting through the first region.

A vehicle head-up display device may include a plurality of first image generation parts embedded in a vehicle body, and configured to provide flat and stereoscopic images in multiple directions, a first optical induction part configured to guide an image signal, provided by the first image generation parts, in one direction, and a first display part configured to implement the image signal, provided by the first optical induction part, as an image recognizable by a driver, thereby implementing augmented reality of a head-up display.
