1. A display device, comprising:
- a luminous flux generator which generates luminous flux including image information;
a reflector plate which reflects the luminous flux generated by the luminous flux generator toward one eye of a viewer;
a head detector which detects a head of the viewer by using at least two pairs of distance sensors;
a controller which controls a position of the reflector plate based on an output from the head detector; and
a driver which drives the reflector plate based on an output from the controller,wherein the head detector includes;
a first pair of distance sensors for measuring a position of the head of the viewer; and
a second pair of distance sensors for determining a coefficient used for measurement based on the first pair of distance sensors.

4. A method for controlling a display device, comprising:
-
generating luminous flux including image information; reflecting the generated luminous flux toward one eye of a viewer; detecting a head of the viewer by using at least two pairs of distance sensors; and controlling a direction of the reflection based on a result of the detection, wherein the detection uses; a first pair of distance sensors for measuring a position of the head of the viewer; and a second pair of distance sensors for determining a coefficient used for measurement based on the first pair of distance sensors. - View Dependent Claims (5)
