It is provided with a direction manipulator for turning and a pointing controller for pointing the imaging direction in the instructed direction.

Further, the stereoscopic image device according to the present invention comprises a direction detector for detecting the direction of the head of the user, instead of the direction operation device.

[0008]

According to the present invention, a twin-lens image is acquired by the twin-lens image pickup device, and the left and right images are displayed to the user on the stereoscopic display. The stereoscopic display projects wide-angle and stereoscopic images by projecting left and right images from two projectors on a curved screen. The user operates the directional manipulator, and the manipulated variable is input to the pointing controller. The pointing controller controls the direction of the twin-lens image pickup device in the direction designated by the user.

Further, the present invention detects the direction of the user's head by a direction detector for detecting the direction of the user's head instead of the direction operation device for instructing the imaging direction, and sets the direction to the direction controller. Output to.

EXAMPLES Example 1. FIG. 1 is an overall configuration diagram of an embodiment of a stereoscopic image device according to the present invention. In this embodiment, as is clear from FIG. 1, a twin-lens image pickup device 1 for acquiring a twin-lens image,
The stereoscopic display 2 for displaying a twin-lens image, the direction operation device 3 for instructing the imaging direction, and the orientation controller 4 for directing the orientation of the twin-lens imaging device 1 in the instructed direction.

Next, the operation will be described. Twin-lens imager 1
Is, for example, a CCD (Charge Coupled D
2) Two cameras, one for the right eye and the other for the left eye, are fixed to a pedestal with the distance between the eyes of a person, and the captured twin-lens image is transmitted to the stereoscopic display 2 using a coaxial cable or the like. . Images of the left and right eyes obtained by the twin-lens imager 1 on the stereoscopic display 2 are displayed on the left and right eyes of the user. The imaging direction can be designated by the user by operating the direction operation device. The operation amount given to the handle 3 is input to the orientation controller 4 and the orientation of the twin-lens image pickup device 1 is controlled according to the operation amount.

Next, the operation of the stereoscopic display 2 will be described in a little more detail with reference to FIG. FIG. 2 is a configuration diagram of the stereoscopic display 2, including the projectors 5 and 6 for projecting a twin-lens image and the projectors 5 and 5.
It is composed of a curved screen 7 for receiving the image projected at 6, and a helmet 8 to which they are attached. The video signals of the left and right eyes obtained by the twin-lens image pickup device 1 are input to the left and right projectors 5 and 6, respectively. The projectors 5 and 6 convert the video signal and project the image on the screen 7 from the front lens. The twin-lens images projected from the projectors 5 and 6 are projected through a distorted lens in order to obtain a distortion-free image when projected onto the curved screen 7. The image projected on the screen 7 is given to the left eye of the user as the image for the left eye, and is given to the right eye of the user as the image for the right eye. Obtainable.

Next, the screen of the stereoscopic display is shown in FIG.
Will be shown with reference to. As shown in FIG. 3, the projection light of the projector 5 is projected onto the screens 7a and 7b, and the projection light of the projector 6 is projected onto the screens 7c and 7d.
The images projected on the screen are given to the eyes of the user at the position of the viewpoint 9. Reference numeral 10 is a partial enlarged view of the areas 7b and 7c of the screen where the left and right images are overlapped with each other, and has a so-called reflective lenticular screen structure.
Due to the characteristics of the lenticular screen with excellent directivity, the left and right parallax images projected from the left and right projectors are reflected by the screen and are given separately to the left and right eyes.
Therefore, the user can obtain a stereoscopic image in the portion where the left and right images of the central portion of the screen overlap. Further, the surfaces of 7a, 7c and 7d, 7b are processed into a saw-tooth shape as shown in partial enlargements 11 and 12, respectively, and the image of the projector 5 at the position of the viewpoint 9 is projected to the left eye of the user. The image of the projector 6 is given to the right eye of the user. Thereby, it is possible to display at a viewing angle equivalent to the viewing angle of the twin-lens image pickup device, and it is possible to provide the user with a wide field of view.

Example 2. FIG. 4 is a diagram illustrating a configuration of a stereoscopic image device including a direction detector 13 that detects the orientation of the head of the user in place of the direction operation device 3 that indicates the imaging direction according to the first embodiment. In the present embodiment, the direction of the head of the user is automatically detected by the direction detector 13, the detected direction is input to the direction controller 4, and the twin-lens imager 1 is directed in that direction.

[0015]

As described above, a twin-lens image is acquired by the twin-lens imager and displayed on a stereoscopic display composed of a projector mounted on a helmet and a curved screen. Since the directional operation device for pointing and the pointing controller for pointing the twin-lens image pickup device in the designated direction are used, a wide-angle and stereoscopic image can be displayed.

Further, since the direction detector for detecting the direction of the head of the user is used to automatically instruct the image pickup direction, the direction detector can detect the direction of the user's head. The eye imager can be directed, and the steering wheel operation can be omitted and the user can be given a sense of direction.
