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.

Abstract
A head-up display apparatus having a structure capable of imaging a user, and enabling an eye position of the user to be accurately calculated is provided. The head-up display apparatus reflects visible light L emitted from display means 2 toward the user D by a combiner member (concave mirror) 4 to form a display image V. The apparatus includes infrared ray emitting means 5 for emitting an infrared ray toward the user D, a mirror member (cold mirror) 3 for reflecting the visible light L emitted from the display means 2 toward the combiner member 4, and transmitting the infrared ray reflected by the user D and the combiner member 4, a plurality of imaging means 6, 7 disposed to face the mirror member 3 for sensing the infrared ray, and each imaging the user D from differing directions, and image processing means 8 for calculating the eye position of the user D based on an image captured by the imaging means 6, 7.
