Abstract:
A free-curved surface Fresnel mirror is disposed inside an HUD unit, and the display light from 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 by using the free-curved surface formed by a free-curved surface Fresnel mirror having a planar shape. A half mirror with a magnifying function configured as a Fresnel mirror is disposed in the image projection area, whereby the half mirror with the magnifying function is provided with a magnifying function.

Claim (Index 1):
A display image projection apparatus 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, wherein\n the projection optical system is equipped with a Fresnel mirror, and the surface shape of the Fresnel mirror is formed in a state in which a free-curved surface shape for correcting aberrations occurring in the optical paths from the display device to a predetermined eye point is divided into a plurality of areas.
