映像を得ることができる。2. Description of the Related Art As is well known, images captured by the human eyes have a stereoscopic effect because images captured by the left and right eyes from different directions are captured as images synthesized by the brain. Utilizing this, two cameras are installed on the left and right,
By synthesizing the images shot toward the respective subjects, it is possible to obtain a stereoscopic image even if the images are projected on a plane.

同一感覚の立体像を得ることができる。Therefore, there has been proposed a stereoscopic camera which supports two cameras on one table and can perform stereoscopic photographing while adjusting the relative position. That is, as shown in FIG. 5, when shooting at the same size, in order to obtain a stereoscopic effect similar to the image captured by the human eyes, the lens positions of the left and right cameras are set to the distance between the left and right eyes of the human (about 65 mm). ) You can take pictures of each subject after separating them. Also, if a zoom lens is used, even if the distance between the human and the subject is farther back, the distance between the left and right cameras is increased and the left and right eyes of the human are oriented in the same direction as the direction of the subject. By taking a zoom image with the aiming at, it is possible to obtain a stereoscopic image with the same sensation as the image captured by a human nearby.

の映像とは異なるものとなることがあった。By the way, in the positioning adjustment according to the object in the conventional stereoscopic camera, one camera is fixed and the other one is horizontally moved to adjust the interval. It was configured to adjust the angle. However, such a conventional positioning adjustment mechanism for a stereoscopic camera has a problem that the line passing through the centers of the two cameras changes with respect to the cameraman each time, making it difficult to capture the subject. Further, particularly in short-distance shooting, since the distance between the subject and each camera is different, the image may not be exactly the same as when viewed from the front.

It is an object of the present invention to provide a positioning adjustment device for a stereoscopic camera that solves the above-mentioned problems by making it possible to adjust the angle by changing the angle in the opposite direction by equal angles.
