Now, in FIG. 5, when the line-of-sight direction detection unit detects that the head position is at position 400b. The output image signal of the TV camera 200b is selected by the manual switching section 220 and displayed on the display section 230. When the g position is at the 400a position, the line of sight direction detection unit 240 similarly determines the head position at 400a.

The output image signal of the TV camera 200a is selected and displayed on the display section 230. Also. A part position is 400c
Similarly, the line of sight direction detection unit 240
It is detected that the head position is at position 400c. The output image signal of the TV camera 200c is selected by the input switching section 220 and displayed on the display section 230. therefore. The observer moves his or her head horizontally. When the head position is at position 400a in Fig. 5, the image shown at +al in Fig. 6 is displayed. When the head position is at position 400b, the image shown in (bl) in Figure 6 can be observed, and when the head position is at position 400c, the image shown in (Cl) in Figure 6 can be observed. The TV camera drive unit 210 drives each TV camera 200a, 200b based on the detection result of the line-of-sight direction detection unit 240.
, 200c in the vertical direction and control the elevation angle of each TV camera. FIG. 7 is a diagram illustrating the relationship between the position of a human head and an object from the side. Now, the 7th
In the figure, when the line-of-sight direction detection unit 240 detects that the head is at the head position 400e, each TV camera drive unit 2]. Oa. 210b210c for each TV camera 200a. 200b, 200
c is driven in the vertical direction, the elevation angle of the TV camera is controlled, and the image shown at tel in FIG. 8 is displayed on the display section 230. Similarly, when part a is at the head position 400f, the image shown in if) of FIG. 8 is obtained. When the head is at the head position 400g, the image shown at Tgl in FIG. 8 is displayed on the display unit 230. In addition, in the embodiment of the present invention. We have explained the case where three image input units are used. It is clear that the present invention can also be implemented using a larger number of image input units. Furthermore, in an embodiment of the present invention. Although we have explained the case where multiple image input units are fixed at multiple positions in the horizontal direction, it may also be realized by moving them continuously according to the horizontal movement of the head. It is clear that the present invention can be implemented using any other image input means. In addition, in the embodiment of the present invention, the angle 31 (the angle between the HTV camera 200a and the TV camera 200b) and the angle 41
1 (Angle between head position 400b and head position 400a)
and the angle 312 (the angle between the TV camera 200c and the TV camera 200b) and the angle 412 (the head position 40
0b and the head position 400c), but if the angles 311 and 411 are completely equal, and if the angles 312 and 412 are completely equal. The relationship between the position of the head and the position of the target object can be observed in exactly the same way as when looking directly at the target object. Similarly, in the vertical direction, if the elevation angle of the TV camera and angles 613 and 614 are exactly equal. It can be observed that the relationship between the position of the head and the position of the target object when directly looking at the target object is exactly the same. Furthermore, if the image input unit is continuously moved in exactly the same way according to the horizontal movement of the head, the relationship between the amount of head movement and the position of the target object when looking directly at the target object is The exact same relationship can be observed. In addition, the angle 31H
angle between TV camera 200a and TV camera 200b)
The angle 411 (!! 1 part position 400b and head position 40
angle with 0a). Similarly, angle 312 (T
angle between the V camera 200c and the TV camera 200b)
When is made larger than the angle 4l2 (the angle formed by the head position 400b and the head position 400c), it is possible to observe an image that looks further into the target object than the position of the head when directly looking at the target object. , it is possible to observe the back side of the target object using a flat display, and it is possible to obtain a effectively large viewing angle. Also. Similarly, if the elevation angle of the TV camera is made larger than angles 613 and 614, the same effect as described above can be obtained in the vertical direction as well. Furthermore, the same effect can be obtained when the TV camera is continuously moved larger than the horizontal movement of the head, or when the TV camera is continuously moved larger than the vertical movement of the head. It will be done. Note that in the embodiment of the present invention, the viewing direction detection unit 240
The input switching unit 220 and T
Although the present invention uses means for displaying an image corresponding to the movement of section a in real time on the display section by driving the TV camera 200 by the V camera drive section 210 or switching the TV camera output, the present invention is not limited to this. A large number of images are taken at random, and these images are transferred to a VTR, magnetic recording device, etc.
Record it on an image recording device such as an optical disc. A method of displaying in response to the movement of the observer's head may also be used.
It is clear that the present invention can be implemented using any other image input means.
