Abstract

An image display device includes: a light source section adapted to emit a laser beam; a drawing section adapted to make a mirror reflect the laser beam, and rotate the mirror to draw an image; a display section adapted to reflect the laser beam to form a virtual image; a moving section adapted to move the drawing section and the display section in conjunction with each other; a visual line detection section adapted to detect a visual line of an observer observing the virtual image; and a control section adapted to control the moving section in accordance with a movement of the visual line.

Claims

1. An image display device comprising:

a light source section adapted to emit a laser beam;

a drawing section adapted to make a mirror reflect the laser beam, and rotate the mirror to draw an image;

a display section adapted to reflect the laser beam to form a virtual image;

a moving section adapted to move the drawing section and the display section in conjunction with each other;

a visual line detection section adapted to detect a visual line of an observer observing the virtual image; and

a control section adapted to control the moving section in accordance with a movement of the visual line.

2. The image display device according to claim 1, wherein

the moving section includes a connection section adapted to connect the drawing section and the display section to each other.

3. The image display device according to claim 1, further comprising:

a protecting section provided with a window section having a light transmissive property,

wherein the display section is disposed in the protecting section.

4. The image display device according to claim 2, further comprising:

a protecting section provided with a window section having a light transmissive property,

wherein the display section is disposed in the protecting section.

5. The image display device according to claim 1, wherein

the display section has a plate having a heat resistance property on which a hologram sheet is disposed.

6. The image display device according to claim 1, wherein

the display section has a frame section on which a hologram sheet is disposed.

7. The image display device according to claim 3, wherein

the window sections are disposed across the display section from each other.

8. The image display device according to claim 4, wherein

the window sections are disposed across the display section from each other.

9. A drawing method comprising:

shooting a pupil of an observer to detect a visual line of the observer;

moving a display section and a drawing section to a place where a laser beam passes through the pupil of the observer; and

emitting the laser beam from the drawing section to the display section to draw a virtual image.
