摘要： There is provided ahead-up display in a vehicle arranged to display a picture, the head-up display comprises a first optical sub-system disposed in an upper region of the windscreen and a second optical sub-system disposed underneath the dashboard of the vehicle proximate a lower region of the windscreen. The first optical sub-system is arranged to output a light field. The first optical sub-system comprises a light source and a spatial light modulator. The light source is arranged to emit light. The spatial light modulator is arranged to receive the light from the light source and spatially-modulated the light in accordance with a computer-generated hologram displayed on the spatial light modulator. The second optical sub-system is arranged to receive the light field from the first optical sub-system and project the light field onto a windscreen of the vehicle to form a virtual image on the windscreen.

摘要： An information provision device, information provision method, and a non-transitory recording medium storing a program for causing a computer to execute the information provision method. Each of the information provision device and the information provision method includes projecting an image light to a light transmission member to display a for-driver information image indicating for-driver information to be provided to a driver of a mobile object in a prescribed display area, and displaying at a first point where a normal for-driver information image is displayed a priority for-driver information image in place of the normal for-driver information image, where the displaying includes displaying the normal for-driver information image at a second point different from the first point for at least some of a period during which the priority for-driver information image is displayed at the first point.

摘要： 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.

摘要： A display device includes a beam generator and a holographic optical waveguide. The beam generator includes a display and is configured to generate beams having image information displayed on the display. The holographic optical waveguide is configured to display an image of a second size at a position at a first distance behind the display device based on the beams having the image information, the second size is a multiple of the first size of the display, and the multiple is greater than 1.
