Abstract
A head-up display comprises an image display device, a virtual image optical system, a housing with a housing opening, an antiglare plate covering the housing opening, a camera for capturing an image of a face area including an eye of a driver, a viewpoint detection device for detecting a viewpoint of the driver based on the image captured by the camera, and a main controller. The camera is installed on a position outside the housing and withdrawn from an optical path of the image light emitted through the housing opening, as well as in an orientation for capturing an image of an area where a face including the eye of the driver is reflected on the antiglare plate. The main controller controls to adjust an emission direction of the image light based on a viewpoint position of the driver detected by the viewpoint detection device.
