Head-up display apparatus
First Claim
1. A head-up display apparatus configured to reflect visible light emitted from display means toward a user by a combiner member to form a display image, the head-up display apparatus comprising:
- infrared ray emitting means for emitting an infrared ray toward the user;
a mirror member for reflecting the visible light emitted from the display means toward the combiner member, and transmitting the infrared ray reflected by the user and the combiner member;
a plurality of imaging means for sensing the infrared ray transmitted through the mirror member, and each imaging the user from differing directions; and
image processing means for calculating the user'"'"'s eye position based on an image captured by the imaging means,wherein the infrared ray emitting means is disposed to face the mirror member and be positioned between the plurality of imaging means.

Abstract
A head-up display apparatus includes an infrared ray emitting unit for emitting an infrared ray toward a user, a mirror member for reflecting visible light emitted from a display toward a combiner member, and transmitting the infrared ray reflected by the user and the combiner member, a plurality of imaging units disposed to face the mirror member for sensing the infrared ray, each imaging the user from differing directions, and an image processing unit for calculating the eye position of the user based on an image captured by the imaging units.
