Abstract

PROBLEM TO BE SOLVED: To manufacture the stereoscopic television receiver at a low cost by using an existing VTR for High Vision. SOLUTION: A High Vision use VTR 20 that is able to conduct recording/ reproduction in full motion up to a High Vision size (1920×1024) and to conduct recording and reproduction at the quadruple speed for an NTSC size (640×480) with mode changeover provision is used, a right parallax image is given from one input terminal A 22 and a left parallax image is given from the other input terminal B 24 and a synchronizing signal denoting the right parallax image and the left parallax image is recorded on a video tape 30 by field recording for each 1/240sec together with the left/right parallax image.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereoscopic television apparatus, and more particularly to a stereoscopic television apparatus that easily realizes a stereoscopic television using a high definition VTR.

[0002]

2. Description of the Related Art Conventionally, a stereoscopic television device has been known and is disclosed in, for example, Japanese Patent Laid-Open Nos. 4-340893 and 64-2.
No. 4693 and the like are known, but these require a special device to be manufactured and require a considerable cost for production.

[0003]

SUMMARY OF THE INVENTION The present invention makes it possible to inexpensively produce a stereoscopic television device by utilizing an existing VTR for high definition.

[0004]

In order to achieve the above object in the present invention, first, in claim 1, it is possible to record and reproduce in full motion up to a high-definition size (1920 × 1035) and an NTSC size ( 640 x 4
80) is equipped with a high definition VTR (20) with mode switching capable of recording and playing back at 4 × speed, and the right parallax image is output from one input terminal A (22) of the external input and the other input terminal B (24). ), A left parallax image is input, and a sync signal indicating the right parallax image and the left parallax image is recorded on the video tape (30) every 1/240 seconds together with the left and right parallax image signals. And a three-dimensional television device.

According to the second aspect of the present invention, it is possible to record and play back in full motion up to a high-definition size (1920 × 1035) and an NTSC size (640 × 48).
0) is equipped with a high-definition VTR (20) with mode switching capable of recording and playing back at 4x speed, and the right parallax image is output from one input terminal A (22) of the external input and the other input terminal B (24). ), The left parallax image is input, and together with these left and right parallax image signals, a synchronization signal indicating the right parallax image and the left parallax image is recorded on the video tape (30) by field recording every 1/240 seconds, and is reproduced. Is a stereoscopic television characterized by reproducing and displaying a right parallax image and a left parallax image as a 1/60 second field image and opening and closing a liquid crystal shutter (82) of glasses (80) with liquid crystal shutters by the synchronization signal. It was a John device.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. As shown in FIG. 1, a high definition VTR (2
0) is prepared. This high definition VTR (20)
Is a high-definition VTR with mode switching capable of full-motion recording / playback up to high-definition size (1920 × 1035) and recording / playback at NTSC size (640 × 480) at 4 × speed. And
The subject (1) is photographed by the right parallax image photographing device (10), and the obtained right parallax image signal is input to the high definition VTR (20) through the input terminal A (22). Similarly, the subject (1) is photographed by the left parallax image photographing device (12), and the obtained left parallax image signal is input to the high definition VTR (20) through the input terminal B (24).

Then, the right parallax image signal and the left parallax image signal are recorded on the video tape (30) as a right parallax image record (32) and a left parallax image record (34) by field recording every 1/240 seconds. . At the same time, a sync signal indicating the right parallax image and the left parallax image is recorded as a sync signal (38).
Is recorded on the video tape (30).

For playback, a high definition VTR
By (20), right parallax image recording (32), left parallax image recording (34), and sync signal recording (3) on the video tape (30).
8) is read out, processed by the video signal processing unit for reproduction (60), the right parallax image and the left parallax image are sent to the monitor television (70) as 1/60 second field video, and reproduced as a reproduction image (72). To do.

At the same time, the liquid crystal shutter (82) of the glasses (80) with liquid crystal shutters is opened and closed by the synchronizing signal, and when the right parallax image is displayed and displayed, the right eye liquid crystal shutter (82) is opened and the left eye is opened. LCD shutter (8
2) is closed. Conversely, when the left parallax image is displayed, the left-eye liquid crystal shutter (82) is opened, and the right-eye liquid crystal shutter (82) is closed. In this way, the viewer can see the stereoscopic image.

[0010]

As described above, the present invention has the following effects. That is, the present invention uses the existing high-definition VTR, so that a stereoscopic television device can be manufactured at low cost without requiring a special device.
