WIPO Patent Application WO/2008/065812
Kind Code:
A1
Abstract:
A head up display unit having such a structure that a user can be imaged regardless
of opening/closing of a combiner member. Visible light (L) emitted from a display
means (2) is reflected by the combiner member (concave mirror)(4) provided operably
toward the user (D) thus forming a display image (V). The head up display unit
comprises a means (5) for irradiating infrared rays toward the user (D), means
(6, 7) for imaging the face of the user (D) by receiving the infrared rays reflected
off the user (D) through the combiner member (4) when it is open and receiving the
infrared rays reflected off the user (D) not through the combiner member (4) when
it is closed, and an image processing means (8) for calculating the positions
of the eyes of the user (D) based on an image picked up by the imaging means (6, 7).
