2. Description of the Related Art Conventionally, as for a device such as a stereoscopic camera as a means for realizing a stereoscopic image, two image devices such as CCD camera devices are installed with an arbitrary convergence angle with respect to an image object. Then, the image signals respectively processed by the signal processing units of the left and right CCD cameras and the like are alternately transmitted to the VTR and the like at the 30 Hz cycle by the image switching device such as the scan converter, and further transmitted to the color monitor and the like. Then the image is displayed. The observer of the monitor wears stereoscopic glasses using an electronic shutter (PLTZ), turns on and off the left and right shutters of the stereoscopic glasses in synchronism with the left and right image display on the color monitor screen, and the left image is displayed on the monitor. When displayed, open the left shutter of the stereo glasses,
When the right shutter is opened and the right image is displayed on the monitor, on the contrary, the monitor image can be stereoscopically viewed by opening the right shutter and closing the left shutter.

[0003]

According to the above-mentioned prior art, it is possible to obtain a stereoscopic image on the monitor by the parallax of the two left and right CCD cameras, but the two CCD cameras for the image object. It is difficult to adjust the left and right parallax, and the stereoscopic image is likely to be out of focus due to the displacement of the image device such as the CCD camera from the proper parallax position, and double display is likely to occur, which hinders clear stereoscopic image display. Left and right 2
Due to the difference in performance of video equipment such as two CCD cameras, the left and right images on the monitor differ in brightness, focus, image quality, etc. Therefore, the stereoscopic image is out of focus, the image quality is deteriorated, etc. There are drawbacks such as not being obtained.

Also, as the visual device itself, two CCs are used.
It requires a jig to install video devices such as D cameras at an arbitrary distance, and it is large and heavy.
When applied to a remote-controlled robot or the like, it is desired to reduce the size and weight.

In view of the above problems, it is an object of the present invention to provide a visual device which can adjust a double-focus display of a stereoscopic image and can obtain a clear stereoscopic image and which is smaller and lighter than a conventional device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, a video device 22 comprises a camera section 1, a lens 2, a CCD 4, a video signal line 8 and a video signal processing device 3, and a support jig 5 and a support plate 9 are fixed to the CCD 4. ing. The fixed pin 7 is passed through the hinge portion 7 of the support jig 5, and both ends of the fixed pin 7 are fixed. The support plate 9 is supported by a support spring 11 whose one end is fixed. The operating portion of the piezoelectric element 10 that operates with a DC voltage is in contact with one surface of the support plate 9. The piezoelectric element 10 has one surface fixed. The piezoelectric element 10 is set with a piezoelectric element power supply 18 including a switch 17 in the circuit. An adjusting screw 14 is installed on the opposite surface of the support plate 9 with a certain gap, and the adjusting screw 14 is supported by a pulley 15, a belt 13 and a servomotor 12. A detailed description of this portion will be given with reference to FIG.

In FIG. 2, the adjusting screw 14 is supported by a pulley 15 having the same screw fitting, and the pulley 15 is supported by a fixed bearing 19 and a bearing support plate 20.
Due to the action of 19, the structure is such that the belt 13 can freely rotate. A rotation prevention shaft 27 is integrated with one end of the adjustment screw 14, and both ends of the rotation prevention shaft 27 are supported by the adjustment screw linear movement groove 28. This makes the belt 13
Also, due to the rotating shaft of the pulley 15, the adjusting screw 14 does not rotate but moves in the linear direction by the screw action of the pulley 15 and the adjusting screw 14. Further, the support plate 9 is pressed by the support spring 11, and the piezoelectric surface of the opposite surface is in contact with the piezoelectric element 10.
Therefore, a gap 29 having an arbitrary length is obtained between the tip of the adjusting screw 14 and the surface of the support plate 9.

The system configuration of this embodiment is shown in FIG. That is, it is composed of the video device 22 described with reference to FIGS. 1 and 2, the VTR device 23, the driver unit 24, the stereoscopic glasses 25, and the monitor device 26.

Next, the operation of this embodiment will be described with reference to FIGS.
4 and FIG. First, the switch 17 of the piezoelectric element power source 18 is turned on and off at a cycle of 60 Hz. This is done by providing the switch 17 with an on / off mechanism of a 60 Hz cycle. As a result, the piezoelectric element 10 repeats the operation of pushing and returning the support plate 9 at a frequency of 60 Hz. This is realized by the push-back operation of the support spring 11 and the piezoelectric element 10. For this reason, the support plate 10 stops using the tip of the adjusting screw 14 separated by the gap 29 of an arbitrary distance as a stopper. That is, when the piezoelectric element 10 is operating, the support plate 9 is prevented from moving at the tip of the adjusting screw, and when the piezoelectric element 10 is not operating, the supporting plate 9 stands still at a position separated by the gap 29. Therefore, the support plate 9 repeats the above-mentioned reciprocating operation in synchronization with 60 Hz. CCD4 is
One end is fixed by the support jig 5, and the hinge portion 6 rotates about the fixing pin 7 as an axis. CCD4
Since one end is attached to the support plate 10, the above 60H
The reciprocating motion between the gaps 29 synchronized with z causes the reciprocating rotary motion about the fixed pin 7.

An image 30 taken by the optical axis 16 of the subject through the lens 2 of the camera section 1 is projected on the CCD 4 with a shift of 60 Hz in synchronism with the reciprocating operation of the CCD 29 between the gaps 29. This video signal is subjected to analog signal processing by the video signal line 8 and the video signal processing device 3, and this analog signal is transmitted from the video device 22 to the VTR device 23, and the video signal is sent to the monitor 26 by the synchronization processing, and the stereoscopic glasses are also used. twenty five
The shutter on / off signal is transmitted to the shutter driver unit 24 for use in the.

This video signal is a projection video signal having a shift of 60 Hz, and it is possible to use one signal for the right and the other signal for the left. The right and left video signals are alternately output in synchronization with 60 Hz and displayed on the monitor 26. Therefore, as a display, a left image is displayed at 30 Hz and a right image is displayed at a 30 Hz cycle, and the monitor itself has a 30 Hz cycle of a normal TV, so that it is possible to obtain image quality comparable to that of a TV. That is, on the monitor 26, the left image 31 and the right image 32 shown in FIG.
It is displayed alternately in the Hz cycle. A stereoscopic image can be obtained by monitoring this image with the stereoscopic glasses 25 that have received a shutter-on / off synchronizing signal from the driver unit 24.

In this case, in the case of image shift due to left and right parallax, the distance of the gap 29 is adjusted by moving the adjusting screw 14 in the direction of linear movement by the operation of the servo motor 12, whereby the reciprocal movement of the CCD 4 is shifted. Adjustment is performed by finely adjusting the deviation of the left and right images by adjusting the size of. Further, the conventional stereoscopic vision device requires two image devices such as CCD cameras, and devices such as a scan converter and a mixer for stereoscopic television cameras that switch signals from the two cameras. In the embodiment, the stereoscopic image processing can be performed by one image device, so that the size and weight of the visual device can be reduced. As another embodiment of the present invention, the same effect can be obtained by fixing the CCD unit 4 and reciprocally moving the lens 2 of the camera unit 1 with a similar mechanism at a frequency of 60 Hz.
