Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a three-dimensional image display device.

[Prior art]

FIG. 1 is a side view of the configuration of a conventional three-dimensional display device. In the figure, (1) is glasses, (2) and (3
) are two left and right photos with parallax for stereoscopic display,
(6) is an eyeglass support part. The conventional three-dimensional display device is configured as described above, and the observer.

The image (2) or (3) with parallax is viewed separately from the left and right eyes through the eye*tl) to obtain a three-dimensional effect (
·Ta. However, with conventional models, it is not possible to place the left and right images in the same position, so the direction of the line of sight is fixed.

Since this method is different from viewing ordinary three-dimensional structures, it has the disadvantage that it requires training, especially when attempting to perform stereoscopic viewing on a large screen. Another drawback is that it is difficult to arrange the left and right images correctly so that they have a three-dimensional effect.

[Summary of the invention]

The present invention has been made for the purpose of improving these drawbacks, and is intended to provide a three-dimensional display device that allows stereoscopic viewing of a large screen to be easily performed, especially by those who have undergone no prior training.

[Embodiments of the invention]

FIG. 2 is a block diagram showing an embodiment of the present invention, (1
) are glasses, +21 and (3) are cathode ray tube display devices, (4) is reflector 1 (51 is a plastic tube display, and mirror images of tube displays (2) and (3) by nine reflectors (4).

In the above configuration, the observer can see the cathode ray tube display (2) and (
The mirror image (5) of step 3) is observed with the left and right eyes as if they were at the same position, as shown by the dashed line in the figure. therefore,
If two images with parallax are shown on a cathode ray tube display, an observer can see them in 3D.

〔Effect of the invention〕

As explained above, this invention allows the left and right images to be mirrored at the same position so that 2% of the images can be easily viewed in 3D even if the person has not undergone 11 training. Since aMJ alignment can be performed, two mi images can be easily placed in the correct position, and it is highly effective as a three-dimensional display device for topography using remote sensing data and the like.

[Brief explanation of the drawing]

FIG. 1 is a side view of a conventional three-dimensional display device, and FIG. 2 is a diagram showing an embodiment of the three-dimensional display device of the present invention. In the figure, (1) is the glasses, (2) and (3) are the plow/tube displays, and (4) is the reflector. In FIG. 2, the same or corresponding parts are designated by the same reference numerals.
