Abstract:
Provided is a head-up display device capable of improving the degree of freedom
of the arrangement position of a plurality of display means or imaging means.
The head-up display device includes a plurality of display means (2 to 4) which
emit visible lights (display lights) (L1 to L3), which are reflected toward a
user (operator) (D1) by a combiner member (wind shield) (W1) so as to form display
images (virtual images) (V1 to V3). The head-up display device includes a micro
mirror device (5) having a plurality of micro plane mirrors aligned in such a manner
that each of the mirrors can move. The micro mirror device (5) controls visible
lights (L1 to L3) emitted from the display means (2 to 4) into a direction for forming
the display images (V1 to V3) by adjusting the angle of the plane mirrors at a predetermined
time interval or individually.
