丑れる。[Detailed description of the invention] [Industrial usage U!ヱ〕 The present invention 1d relates to a stereoscopic imaging device for a stereoscopic imaging system. For example, by installing two cameras in parallel facing the entire subject and capturing images, the right eye image obtained with one camera is The image information and the image information for the left eye obtained by one other camera are displayed on the screen at the same time, so that each image information can be seen independently by the left and right eyes of the viewer.
l) This relates to the improvement of the imaging system in a stereoscopic video system that enables full stereoscopic viewing.0 Note that the imaging devices referred to here include @J camera included.
従来より、視聴者に右眼用の画像情報と左眼用の画像情
報を同時に左右の眼に独立に見せることに工って再生画
像を立体的に見せるようにした立体視映像システムが種
々提案されている。In the past, various stereoscopic video systems have been proposed that allow the viewer to view image information for the right eye and image information for the left eye simultaneously and independently to the left and right eyes, thereby making the reproduced image appear three-dimensional. has been done.
例えば、いわゆる「二眼方式ｊと呼ばれる立体テレビジ

生するようになっている。For example, a stereoscopic television receiver called a so-called "two-lens type J" uses image information 2R for the right eye displayed in a predetermined color (for example, red) on the screen 1 of the television receiver as shown in FIG. and other prescribed colors (e.g. blue)
All 2L of image information for the left eye displayed on the screen are played back at the same time.
そして、視聴者Ｍは左右異なる色（例えば上記１σ１７

見ることができる。Then, the viewer M sees different colors on the left and right sides (for example, the above 1σ17
Image information 2R and 2L (1) If you look at the entire screen 1 through colored glasses Gt (red for the right eye and blue for the left eye according to each predetermined color), the right I11! R can see only the image information 2R for the right eye, and the left eye can see the left eye image F?
Only the J report 2L is visible, and the image can be viewed three-dimensionally as if the reproduced image 2 were not on the screen 1 but at point A in FIG.
ところで、上述の如き右眼用の画像情報２Ｒと左眼用の
