Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Utilization Labor Capital] The present invention relates to an image display device that allows a viewer to perceive an object three-dimensionally.

[Conventional technology]

-J', In order to realize stereoscopic vision in J, the information representing the object may be displayed with a positional shift so that the information enters the left and right eyes of the viewer separately. In such a method, for example, the shape of an object that should enter the left and right eyes is drawn in red and blue on a display device such as a CRT, and the viewer wears special glasses with red and blue filters on the left and right sides, respectively. There is a way to wear it and perceive a 3D image. There is also a method of realizing stereoscopic vision using polarized lenses by utilizing the phase difference of light.

[Problem that the invention seeks to solve]

The conventional method described above requires the viewer to wear special glasses, which may be cumbersome, and the method that utilizes color differences does not allow stereoscopic viewing using color. The problem with the method using deflection is that it cannot be realized at low cost.

This invention was made to solve this problem, and allows for color display without the need for special glasses.
An object of the present invention is to obtain an image display device that can realize stereoscopic vision at low cost.

[Means for solving problems]

An image display device according to the present invention includes a display device;
a deflection plate provided on the display device and formed with a plurality of lenses in a predetermined pattern that refracts image information for each required number of pixels on the display device so that it enters the left eye and the right eye of the viewer, respectively; It is equipped with a control circuit that divides the image to be displayed for each required number of adjacent pixels into image information for the left eye and image information for the right eye, which have parallax necessary for stereoscopic vision, and displays them on the display device. be.

[Effect]

In this invention, image information for the left eye and image information for the right eye having parallax displayed on the display device by the control circuit are incident on the left eye and right eye of the viewer, respectively, via the deflection plate.

[Embodiment] FIG. 1 is a diagram showing an embodiment of an image display device of the present invention. In this figure, 1 is a plasma display which is a display device, 2 is a deflection plate, and semi-cylindrical (semi-cylindrical) convex lenses 2n are formed continuously in the horizontal direction. 3 is a control circuit which includes an image memory 3a associated with the pixels of the plasma display 1, and this image memory 3.
and a microcomputer 3b that accesses a. Then, when the image of the object is written into the image memory 3a by the microcomputer 3b, the corresponding pixel emits light. Since this writing can be performed freely using the program of the microcomputer 3b, image information for the left eye and image information for the right eye are alternately displayed for each pixel in the lateral direction of the convex lens 2a, corresponding to the image to be displayed. Write it so that it becomes .

Next, the operation will be explained using FIG. 2. In this figure, the same symbols as in FIG. 1 indicate the same parts, P1 to PIO are pixels on the plasma display 1, EL, EIll.
are the viewer's left and right eyes, AL and Al1, respectively.
1 is the line of sight of the left eye EL and right eye EI11, respectively.

Now, pixels PL, P3. P5. P7. P9 displays an image to be incident on the right eye ER based on the information in the image memory 3a of FIG. 1, and pixels P2. P4, P6. P8. P
An image that should be incident on the left eye EL is displayed on the LO.

Since the pitch of the convex lenses 2a is twice that of the pixels, the pixels P1, P3, . P5. P7. The light from P9 is directed toward the main pixel P2. P4. P6. P8
．． The light from P 10 is bent in the direction of the line of sight AL force. Therefore, pixels PI, P3. P5. P7. The light from P9 is transmitted to the right eye E area, and from pixel P2. P4. P6. P8. The light from the PIO enters the left eye EL, allowing the viewer to perceive a three-dimensional image.

Furthermore, since conventional two-dimensional images can be obtained, there is no fear that the display will become a display for special purposes, and it can be easily applied to general home televisions. Furthermore, since it becomes easier to recognize the shape three-dimensionally, it can also be applied to the design of CAD/CAM etc.

In the above embodiment, the plasma display 1 was used as the display device, but in addition to this, a CRT
, light emitting diode displays, liquid crystal displays, etc.

〔Effect of the invention〕

As explained above, the present invention includes a display device,
A deflecting plate provided on the display device and having a plurality of lenses formed in a predetermined pattern for refracting image information for each required number of pixels on the display device so as to enter the viewer's left eye and right eye, respectively; The present invention includes a control circuit that causes the display device to display an image to be displayed for each of the required number of pixels with the parallax required for stereoscopic vision, dividing it into image information for the left eye and image information for the right eye.
Image information for the left eye and image information for the right eye, which have parallax, are incident on the left eye and the right eye, respectively, and there is an effect that color display and stereoscopic vision can be realized at low cost without the need for special glasses etc. .
