Abstract

A screen for imaging a group picture of view point pictures is arranged and a screen shake detecting means and a means for correcting and controlling the group picture of the view point pictures projected on a screen to a proper position are provided.

Claims

1. A projection-type three-dimensional display apparatus comprising means for controlling and imaging rays of light constituting view point pictures to emit the rays of light constituting the view point pictures including parallax information on view points from a surface of a three-dimensional picture arranged in a space, wherein the view point pictures including the plurality of parallax information are arranged on a two-dimensional plane corresponding to the respective imaging means, the projection-type three-dimensional display apparatus comprising:

means for projecting a group picture of the view point pictures including the plurality of parallax information and a screen for imaging the group picture of view point pictures, as a means for arranging the group picture of view point pictures including the plurality of parallax information, which are arranged just behind the means for controlling and imaging the rays of light;

means for detecting the shake of the screen; and

means for correcting and controlling the group picture of view point pictures projected on the screen to a proper position.

2. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the means for detecting the shake of the screen, an angular velocity sensor is used.

3. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the means for detecting the shake of the screen, an acceleration sensor is used.

4. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the means for detecting the shake of the screen, an image pickup device is used.

5. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the means for detecting the shake of the screen, a means for detecting the shake of reflected light which is reflected on the screen is used.

6. The projection-type three-dimensional display apparatus according to claim 1,

wherein the means for correcting and controlling the group picture to the proper position controls a picture cutout position of the means for projecting the group picture.

7. The projection-type three-dimensional display apparatus according to claim 1,

wherein the means for correcting and controlling the group picture to the proper position corrects the projection picture by controlling the projection position of the means for projecting the group picture using an actuator.

8. The projection-type three-dimensional display apparatus according to claim 1,

wherein the means for correcting and controlling the group picture to the proper position corrects the projection picture by controlling the means for projecting the group picture using an optical means.

9. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the means for controlling and imaging for emitting the element picture including the picture information on the view points, a pinhole array is used.

10. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the means for controlling and imaging for emitting the element picture including the picture information on the view points, a convex lens array is used.

11. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the means for controlling and imaging for emitting the element picture including the picture information on the view points, a lenticular lens array is used.

12. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the means for controlling and imaging for emitting the element picture including the picture information on the view points, a hologram lens array is used.

13. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the projecting means, a transmission-type liquid crystal is used.

14. The projection-type three-dimensional display apparatus according to claim 1,

16. The projection-type three-dimensional display apparatus according to claim 1,

wherein as the projecting means, an organic EL luminous body array is used.

17. The projection-type three-dimensional display apparatus according to claim 16,

wherein as a light source of the projecting means, a LED is used.

18. The projection-type three-dimensional display apparatus according to claim 1,

wherein as a light source of the projecting means, an organic EL is used.

19. The projection-type three-dimensional display apparatus according to claims 1,

wherein as the reflective-type liquid crystal of the projecting means, a reflective-type vertical alignment liquid crystal projection element is used.

20. The projection-type three-dimensional display apparatus according to claim 1,

wherein the screen and the means for controlling and imaging the rays of light are integrated.

21. The projection-type three-dimensional display apparatus according to claim 1,

wherein a liquid crystal screen capable of changing the control of the transmittance of the screen in accordance with surrounding brightness is used.

22. The projection-type three-dimensional display apparatus according to claim 1,

wherein when the image pickup device is used as the means for detecting the shake of the screen, it detects an optical flow of the screen acquired by the image pickup device through the picture process to detect the direction and amplitude of the shake.

23. The projection-type three-dimensional display apparatus according to claim 1,
