本発明は立体テレビジョンにl1Fl−!IIるもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Technical field of manifestation] The present invention applies to stereoscopic television. II.
[発明の技術的背景とその問題点]
立体テレビジョンには種々の方法が試みられでいるが、
第1図、第2図は、その代表例の基本的概念を示すもの
である。[Technical background of the invention and its problems] Various methods have been tried for stereoscopic television, but
1 and 2 show the basic concept of a typical example.
第1図において、テレビカメラ11.12はそれぞれ右
眼用、左眼用の像を撮影し、−映像混合器2でたとえば
第1フィールドは右眼用の像、第2フィールドは左眼用

で作られた駆動手段4に入力する。In FIG. 1, the television cameras 11, 12 take images for the right eye and the left eye, respectively; The left and right video signals are mixed and combined alternately and sent to the TV3. In TV3, the image from the right camera appears in the first field, and the image from the left camera appears in the second field. The vertical synchronization signal of this video signal is taken out from the TV receiver and inputted to a driving means 4 made of an electric shutter such as a PLZT1 liquid crystal.

タ51.52を交互に駆動さUる。The driving means 4 opens the right eye shutter 51 and closes the left eye shutter 52 when the right eye image appears on the TV 3.
When the left eye image appears, the electric shutters 51 and 52 are driven alternately so that the image becomes the opposite.

式が第1図のブロック図に示されている。The block diagram of FIG. 1 shows a method for observing a three-dimensional image through a shutter type mirror.

1図と同様の方式で立体像を観察する。、
しかし、従来のこの方式では、シャッタ式眠鏡をかけな

ない、という問題点がある。X-rays are emitted from the X-ray tubes 21 and 22 alternately for each field or frame iD, and this is transmitted to the X-ray fluorescence intensifier tube 23.
The signal is received by the vidicon 24, converted into an electrical signal, and thereafter, a three-dimensional image is observed in the same manner as in FIG. However, this conventional method has a problem in that the right eye image and left eye image become two Φs, making it impossible to view TV images unless a shutter-type sleep mirror is used.
[発明の目的]

It is intended for the purpose of providing.

In 3D preview, the image of the subject can be recognized in 3D by opening and closing alternately in synchronization with the switching cycle of each field or frame of the right image. One frame is taken at each position of the visible convergence angle, and in synchronization with this, the right eye,
The device is characterized by a system that enables stereoscopic vision when observing through a sleep mirror that alternately blocks the left eye, and normal vision when observing without passing through the left eye.
[発明の実施例] 以下に本発明の実施例を詳細に説明する。[Embodiments of the invention] Examples of the present invention will be described in detail below.
第3図にのように、被写体を中心にテレビカメラ31を
回転移動させ、映像混合器2で各フィールド毎に混合9
合成してTV31に送り出し、各フィールド毎に同期さ

51.52を駆動させる。As shown in FIG. 3, the television camera 31 is rotated around the subject, and the image mixer 2 mixes 9 for each field.
The signals are synthesized and sent to the TV 31, and the electric shutters 51 and 52 of the shutter-type sleep mirror are driven via the driving means 4 in synchronization with each field.
ところで、被7y体を立体視するには両眼と被写体のな

ている。したがって、テレビカメラ31を1/30毎に
1.5°の速さで回転させて撮影することにJ、って、
これをテレビ映像として映し出すときは、正常の映像と
して観察される。By the way, it is known that in order to view a subject 7y stereoscopically, the angle formed between both eyes and the subject (convergence angle) needs to be around 1.5 degrees. Therefore, we decided to rotate the TV camera 31 at a speed of 1.5° every 1/30th to take pictures.
When this is displayed as a television image, it is observed as a normal image.
一方、第4図のように位置AにおいてフレームF!、位

観察するようにづればよい。On the other hand, as shown in FIG. 4, at position A, frame F! , frame F2 at position B, hereafter, take two fields for each frame in the same manner as in position B and observe with a mirror with a shutter set. That is, when the camera rotates clockwise, the second field For example, if you operate the shutter of a sleep mirror with a shutter set in synchronization with each field so that the first field is observed with the right eye and the first field with the left eye, for example, field F12
, F21, F22, and Fat are recognized as images with a convergence angle, and stereoscopic viewing becomes possible. When photographing in a counterclockwise direction, the second field can be observed with the left eye, and the first field can be observed with the right eye.

る。In the above embodiment, an example was explained in which the camera is continuously moved to take pictures. If the image is recorded in an appropriate manner such as in a memory, it is possible to continuously project it later and observe a three-dimensional image. The same applies to X-ray television.
