Three-dimensional image display apparatus
View Patent ↗The three-dimensional image display apparatus includes the following structural elements: an optical system including a concave mirror, and a light transmitting section provided to the concave mirror at a boundary between a first space and a second space, the optical system forming a real image in the second space, with an aid of the concave mirror, of an object disposed in the first space available on the concave mirror; and an image output device disposed at a place so as not to substantially block an optical path of light rays forming the real image of the object.
1. A three-dimensional image display apparatus comprising:
an optical system including:
a concave mirror; and
a light transmitting section provided to the concave mirror at a boundary between a first space and a second space, the optical system forming a real image in the second space, with an aid of the concave mirror, of an object disposed in the first space available on the concave mirror;
an image output device positioned so as not to substantially block an optical path of light rays forming the real image of the object; and
an optical element switchable between a light-transmission mode and a light-diffusion mode or an optical element switchable between a light-transmission mode and a light-shielding mode is disposed at the light transmitting section.
2. The three-dimensional image display apparatus according to claim 1 , wherein the image output device is a projector projecting an image on the object disposed in the first space.
3. The three-dimensional image display apparatus according to claim 1 , wherein the image output device is a display displaying an image shot by a camera shooting the second space.
4. The three-dimensional image display apparatus according to claim 1 , wherein a light transmitting member is disposed at the light transmitting section.
5. The three-dimensional image display apparatus according to claim 1 , further comprising an object replacement mechanism that changes the object to be disposed in the first space.
6. A three-dimensional image display apparatus comprising:
an optical system including:
a first concave mirror; and
a second concave mirror having a light transmitting section, and disposed so that a reflective surface of the second concave mirror confronts a reflective surface of the first concave mirror, the light transmitting section being placed at a boundary between a first space available inside the second concave mirror and a second space available outside the second concave mirror, the optical system forming in the second space a real image of an object placed on a bottom face of the first concave mirror disposed in the first space;
an image output device disposed around a connecting section connecting the first concave mirror and the second concave mirror; and
an optical element switchable between a light-transmission mode and a light-diffusion mode or an optical element switchable between a light-transmission mode and a light-shielding mode is disposed at the light transmitting section.
7. The three-dimensional image display apparatus according to claim 6 , wherein the image output device is a projector projecting an image on the object disposed in the first space.
8. The three-dimensional image display apparatus according to claim 6 , wherein the image output device is a display displaying an image shot by a camera shooting the second space.
9. The three-dimensional image display apparatus according to claim 6 , wherein a light transmitting member is disposed at the light transmitting section.
10. The three-dimensional image display apparatus according to claim 6 , further comprising an object replacement mechanism that changes the object to be disposed in the first space.
11. A three-dimensional image display apparatus comprising:
an optical system including:
a concave mirror; and
a light transmitting section provided to the concave mirror at a boundary between a first space and a second space, the optical system forming a real image in the second space, with an aid of the concave mirror, of an object disposed in the first space available on the concave mirror; and
an optical element switchable between a light-transmission mode and a light-diffusion mode or an optical element switchable between a light-transmission mode and a light-shielding mode is disposed at the light transmitting section.
