Abstract: A light guide member includes an incident portion, an emission portion, a reflection portion, and an inclined portion. An internal reflection angle inside the reflection portion and the emission portion is larger than an incident angle of an external light with respect to a first normal line that is a normal line of the emission portion. A first inclination angle that is an inclination angle of the incident portion with respect to the first normal line is smaller than the internal reflection angle. A height from the emission portion to a second side of the incident portion is larger than a distance between the emission portion and the reflection portion. A second inclination angle that is an inclination angle of the inclined portion with respect to the first normal line is smaller than the internal reflection angle.

Abstract: A blind spot display device displays an image of blind spot blocked by an obstacle, and includes an incidence surface, a light guide member, a first reflecting surface closed to a display region, a second reflecting surface close to the blind spot, and multiple prism portions protruding toward the display region. An external environment light beam enters the incidence surface, reflects alternately on the first and second reflecting surface while passing through the light guide member, and emits toward the display region through the prism portions. Apexes of the prism portions are arranged in a three dimensional manner not along a plane.

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: Each of a plurality of optical elements that are arrayed in a lattice pattern in a screen member which diffuses a laser beam incident from a projector to guide the laser beam toward a projection surface has a curved surface on a side thereof, and the curved surface has a common convexly curved shape, and diffuses the laser beam which is emitted from the curved surface toward the projection surface. The respective optical elements include a plurality of reference elements which serve as a reference and a plurality of peripheral elements which are adjacent to the respective reference elements. The respective reference elements and the respective adjacent peripheral elements are formed by offsetting surface vertexes of the curved surfaces in a stepwise manner. Offset amounts generated between the respective reference elements and the respective adjacent peripheral elements are different from each other.

Abstract: A head-up display apparatus projects a display image onto a projection surface of a windshield so that a viewer views a virtual image of the display image from an eye box. A screen used in the apparatus is constructed of a plurality of micromirrors. Each micromirror has a convex surface portion being curved to magnify a laser beam toward the eye box. A scanned surface of the screen is provided by an array of the convex surface portions. In a cross section intersecting the scanned surface, adjacent convex surface portions have different curved shapes. Thus, brightness unevenness of the display image caused by interference of laser beams can be reduced while maintaining a simple structure of the screen such as a microlens array.

Abstract: A head-up display (10) equipped to a vehicle includes a front view information acquisition unit (22, S110, S120), a virtual image display unit (22, S180), and a size adjustment unit (22, S140-S160). The front view information acquisition unit acquires front view information indicative of an object existing on a travelling road of the vehicle. The virtual image display unit controls lights generated for displaying an object marker corresponding to the object indicated by the front view information acquired by the front view information acquisition unit to be reflected on a windshield (6) and displays the object marker as a virtual image in front of the vehicle. When the object is positioned ahead of the virtual image of the object marker in a traveling direction of the vehicle, the size adjustment unit adjusts a size of the object marker so that a length of the object marker in a width direction of the vehicle is at least equal to or longer than a display reference length, which is defined as a length of a line segment that connects, along the width direction of the vehicle and passing through the position where the virtual image of the object marker is formed, a straight line connecting a right eye of a driver of the vehicle with the object and another straight line connecting a left eye of the driver with the object.
