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 translation: 车辆的图像合成装置包括图像发生器和误差检测器。 从配置到车辆的多个摄像机使得每个照相机的成像区域与相邻摄像机的成像区域部分重叠，图像生成器获取分配给各个摄像机的区域的图像，并且合成所获取的图像以生成围绕 从车辆上方观察的车辆。 错误检测器检测相机中的错误。 当误差检测器检测到相机中的故障相机时，图像发生器从与相机相邻的相机拍摄的图像中获取与由故障相机拍摄的图像重叠的重叠部分，使用重叠部分来生成 合成图像，并且将图像增强应用于重叠部分。

Abstract: A head-up display device displays a near virtual image and a far virtual image formed at different positions. The head-up display device includes an extension optical element, in addition to a first display surface that luminously displays a near display image and a second display surface that luminously displays a far display image. The extension optical element includes a reflective surface disposed on an optical path of light of the far display image. The extension optical element makes a far optical path distance of the far display image longer than a near optical path distance of the near display image by reflection of light by the reflective surface. The extension optical element has a transmission part that transmits light of the near display image in an area overlapping an optical path of light of the near display image.

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: In a head-up display, a cover member includes a first transmissive member and a second transmissive member that transmit a light beam including an image generated by an image generation unit. The first transmissive member is formed to face upward from a front end to a rear end. Likewise, the second transmissive member is formed to face upward from a front end to a rear end. The rear end of the first transmissive member is offset to an upper side from the front end of the second transmissive member.
