Abstract: A head-up display device includes: a screen having a display area to which light is projected to image a virtual image; an outer housing that holds the screen; a scanner unit having a scanner oscillating about a virtual scanning axis to draw a display image in the display area by scanning of the scanner; and a scanner housing held by the outer housing and holding the scanner unit. The outer housing and the scanner housing have an adjustment structure to enable an adjustment of an emission direction of light emitted from the scanner housing at least around the scanning axis by a relative rotation of the scanner housing with respect to the outer housing about a virtual adjustment axis intersecting the scanner unit.

Abstract: A projection type image display device includes a processor having a measuring part for performing a three-dimensional measurement of an A-pillar and a projection range controller for controlling a projection range of an image light, which is matched to an A-pillar surface based on a result of the three-dimensional measurement. Thus, the projection of an image onto the A-pillar surface by the projection type image display device is easily performed regardless of whether the A-pillar surface is a two-dimensional flat surface or a three-dimensional surface. The projection type image display device also directs a retro-reflective component in a reflected image light away from a driver's seat based on a positioning of an image projection device. Speckled uneven image brightness on an image display surface is thereby prevented.

Abstract: An image synthesizer apparatus for vehicle includes an image generator and an error detector. From multiple cameras arranged to a vehicle so that an imaging region of each camera partially overlaps with an imaging region of an adjacent camera, the image generator acquires images of areas allocated to the respective cameras, and synthesizes the acquired images to generate a synthetic image around the vehicle viewed from a viewpoint above the vehicle. The error detector detects errors in the cameras. When the error detector detects a faulty camera in the cameras, the image generator acquires, from the image captured by the camera adjacent to the faulty camera, an overlap portion overlapping with the image captured by the faulty camera, uses the overlap portion to generate the synthetic image, and applies image reinforcement to the overlap portion.

Abstract: A head-up display device is for projecting display light onto a projection member. The head-up display device includes a display, a reflecting member, an outside light prevention portion, and a state controller. The display emits the display light. The reflecting member reflects the display light emitted from the display in a reflection direction to project the display light onto the projection member. The outside light prevention portion changes between an entering state in which outside light is able to enter the display and a preventing state in which outside light is prevented from entering the display. The state controller controls the outside light prevention portion to be (i) in the entering state when the display light is projected onto the projection member and (ii) in the preventing state when the display light is not projected onto the projection member.

Abstract: A projection type display device configured to display an image on a window while also providing a view through the window. The projection type display device has a plurality of reflection portions arranged on a windshield for reflecting an image light that is projected from an image projection device and displaying a superposed display image onto the windshield. Further, since (i) the plurality of reflection portions are arranged on the window along a lateral direction with a lateral interval interposed at positions between two reflection portions, (ii) a lateral width of each of the plurality of reflection portions is less than the minimum human pupil diameter, and (iii) the lateral interval between the two reflection portions is equal to or greater than the lateral width of the reflection portion, the view of the vehicle occupant through the windshield is also sufficiently ensured.

Abstract: A head-up display device projects a near display image and a far display image onto a windshield to visibly display a near virtual image and a far virtual image imaged at different positions from each other. The head-up display device includes a magnification optical element and a correction optical element in addition to a first display surface that emits and displays the near display image and a second display surface that emits and displays the far display image. The magnification optical element magnifies the light emitted from the first display surface and the second display surface and reflects the light toward the windshield. The correction optical element is provided in an optical path of the light of the far display image, and corrects an optical influence, together with the magnification optical element, to be generated in the far virtual image by the reflection on the windshield.
