[0029] As shown in FIGS. 4 and 5, the cameras 15 capture the entire area outside the stereoscopic image display device 10. The image processing device 31 synthesizes the images captured by the multiple cameras 15. In this way, a continuous panoramic image of the entire range outside the stereoscopic image display device 10 is generated. The detection device 32 detects the position of the observer based on the omnidirectional image synthesized by the image processing device 31. When the observer A is at position Aa, the face position detection device 32 sets position Aa as the reference position. For example, when position Aa is the reference position, observer A's position A Identify a as the angle θ0.

[0032] On the other hand, when the observer A moves from the position Aa to the position Ac, the face position detection device 32 performs, for example, The position Ac of the observer A when the position Aa is the reference position is specified as the angle θc. The face table control device 36 controls the display to match the position Ac of the observer detected by the face position detection device 32. The turntable 13 is rotated by an angle θc so that the ray 12 faces the display 1. The rendering device 33 moves the face position detector 32 to the position of the viewer. For example, the rendering device 33 may A left oblique image of the virtual object is formed. The background image behind the display 12c is obtained from the continuous images of the entire surroundings that are synthesized by the device 31. Then, the image synthesis processing device 35 extracts and acquires the background image acquired by the background image processing device 34. The image of the virtual object formed by the rendering device 33 is superimposed on the front of the background image. A composite image is generated, and the composite image of the generated virtual object image and the background image is displayed on the display. Display it on Ray 12c.

[0033] As shown in FIG. 6(a), when an observer A is at a position Aa, the display 12 is The display 12a is moved to face the position Aa of A. forms a front image of the virtual object 101 according to the observer's position Aa.

[0046] When observer A rotates the display 12 every time he moves a small amount, The turntable driver 14 rotates the turntable 13 frequently, and the motor is constantly The motor generates a driving sound, and the observer A easily perceives the driving sound of the motor as noise. The table control device 36 turns when the position of the observer A moves within the angles θb and θc. The table 13 is not rotated. However, the rendering device 33 detects the position of the observer A when the observer A moves slightly.
