2. Description of the Related Art For pseudo-stereoscopic viewing, for example, first, a predetermined image is photographed by two video cameras separated by an interpupillary distance, and three-dimensional (3D) software is created.
It is common to stereoscopically view the image with parallax of this software by viewing the image for the left eye with the left eye and the image for the right eye with the right eye. An example of the 3D stereoscopic vision device used for this pseudo stereoscopic vision will be specifically described with reference to FIG. 16. Reference numeral 100 in FIG. 16 is a stereoscopic projector device as the 3D stereoscopic vision device. This stereoscopic projector device 100 stores images (images) corresponding to the left eye and the right eye in two video disks or cassettes as software, and stores them in two player 1
01L and 101R are simultaneously started and reproduced via the commander 102 of the remote control, and projected on the same screen 104 by the upper and lower two projectors 103R and 103L which are orthogonally polarized (or circularly polarized). This is what is seen with the polarized glasses 105. The screen 104 is made of a surface material that reflects the projection light as it is without changing the polarization direction.

However, in the conventional stereoscopic projector device 100, when a 3D stereoscopic video signal is input, it looks stereoscopic, but when a normal two-dimensional video signal is input, the left eye is used. Moreover, since the same image is obtained for the right eye, there is the inconvenience that the image becomes flat without a stereoscopic effect. In addition, the number of video discs, which are 3D software, is not very large, and it is expensive to stereoscopically view.

FIG. 2 shows an example of an electric circuit of the pseudo three-dimensional processing circuit 6 used in the three-dimensional stereoscopic vision apparatus 1. When a normal 2D video signal (video signal of image 4) is applied from the VTR 5 to the pseudo three-dimensional processing circuit 6, the video signal is divided into two via the sync signal deleting circuit (Sync deletion) 13 and one of the video signals (right The video signal of the eye image 4R) is laterally displaced by the delay line (DL) 14. Here, since it is necessary to change the lateral shift amount according to the number of inches of the monitor screen of the cathode ray tube 3 of the television receiver 2, the delay line 14 is variable and can be adjusted by the operation knob 7. On the other hand, the sync separation circuit (S
sync SEP) 15 to extract the sync signal and
The signal of A and B is switched for each field by the switcher 17 via the / ODD discrimination circuit 16. Thereafter, when a sync (SYNC) is added by the sync signal insertion circuit (insertion Sync) 18, a signal as shown in FIG. 3 is output. In the signal C of FIG. 3, τ of the signal B is blanked. It should be noted that the images 4L and 4R obtained by moving the pupil distance D in the lateral direction from the normal 2D image 4 are easily created by laterally shifting the images 4L and 4R by using, for example, the scroll function of a commercially available digital signal processor.
