Abstract:
An aspherical mirror or a free-curved surface mirror is disposed inside an HUD unit, and the display light of a display device is emitted to the image projection area of the windshield of a vehicle. A distortion correction function for suppressing aberrations is provided on the reflecting surface of the free-curved surface mirror. A half mirror with a magnifying function configured as a Fresnel mirror is disposed in the image projection area of the windshield, whereby the half mirror with the magnifying function is provided with a magnifying function.

Claim (Index 1):
A display image projection system equipped with:\n a display image projection unit having a housing, a display device accommodated in the housing, and a projection optical system accommodated in the housing and used to emit the display image of the display device in a predetermined direction and an optically reflecting member disposed on the windshield of a vehicle or in the vicinity thereof and used to reflect at least part of the optical image emitted from the projection optical system and to guide the part to a predetermined eye point, wherein the projection optical system has at least one aspherical mirror having a distortion correction function for correcting aberrations occurring in the optical paths from the display device to the eye point, and the optically reflecting member has a Fresnel mirror, and the Fresnel mirror has an optically magnifying function for magnifying an image to be formed in the optical paths from the display device to the eye point.
