Abstract

An image display device displays a stereoscopically two-dimensional image, improving its direction effect. A first display displays a first image on a first screen, an image transmission element is in a light path for a display light component of the first image and transmits the display light component of the first image so a real image of the first image appears on an image forming surface opposite the first screen as a stray image. A second display displays a second image on a second screen as a directly visible image so the stray image is observable from an observation position. A controller controls at least either the first or second display based on a relative position in a predetermined spot displayed in the directly visible image with respect to an intersection line of the image forming surface and the second screen so the stray and/or directly visible image changes.

Claims

1-8. -8. (canceled)

9. An image display apparatus comprising:

a first displaying device for displaying a first image on a first screen;

an image transmitting device which is disposed on an optical path of display light which constitutes the first image and which transmits the display light which constitutes the first image so as to display a real image of the first image as a floating image on an image formation surface located in a space on an opposite side to the first screen;

a second displaying device for displaying a second image on a second screen as a direct-view image so as to be viewed from an observation position at which the floating image can be observed; and

a controlling device for controlling at least one of said first displaying device and said second displaying device such that at least one of the floating image and the direct-view image changes, on the basis of a relative position of a predetermined spot displayed in the direct-view image with respect to an intersection line between the image formation surface and the second screen.

10. The image display apparatus according to claim 9, wherein said controlling device controls at least one of said first displaying device and said second displaying device to display a predetermined type of information related to the predetermined spot displayed in the direct-view image, as the floating image.

11. The image display apparatus according to claim 10, wherein said controlling device controls at least one of said first displaying device and said second displaying device to display the information as the floating image if the predetermined spot displayed in the direct-view image is located in a floating image display range in the second screen.

12. The image display apparatus according to claim 11, wherein the floating image display range covers a predetermined distance in front of and behind the intersection line in a depth direction with respect to a user of said image display apparatus.

13. The image display apparatus according to claim 9, wherein

said image display apparatus further comprises a position detecting device for outputting a position signal corresponding to a position of a detected object, and

said controlling device controls at least one of said first displaying device and said second displaying device on the basis of the outputted position signal such that the relative position of the predetermined spot changes in accordance with the position of the detected object.

14. The image display apparatus according to claim 9, wherein

the direct-view image is a map image, and

the floating image is an image of a building, a road, a sign, or an instruction view.

15. The image display apparatus according to claim 9, wherein

the direct-view image is an image of a list about a predetermined item, and

the floating image is an image of detailed information or another list.

16. The image display apparatus according to claim 9, wherein

said image display apparatus further comprises a communicating device for communicating with another apparatus, and

said communicating device communicates with the another apparatus such that the another apparatus operates on the basis of the outputted position signal.

17. The image display apparatus according to claim 10, wherein

said image display apparatus further comprises a position detecting device for outputting a position signal corresponding to a position of a detected object, and

said controlling device controls at least one of said first displaying device and said second displaying device on the basis of the outputted position signal such that the relative position of the predetermined spot changes in accordance with the position of the detected object.

18. The image display apparatus according to claim 11, wherein

said image display apparatus further comprises a position detecting device for outputting a position signal corresponding to a position of a detected object, and

said controlling device controls at least one of said first displaying device and said second displaying device on the basis of the outputted position signal such that the relative position of the predetermined spot changes in accordance with the position of the detected object.

19. The image display apparatus according to claim 12, wherein

said image display apparatus further comprises a position detecting device for outputting a position signal corresponding to a position of a detected object, and

said controlling device controls at least one of said first displaying device and said second displaying device on the basis of the outputted position signal such that the relative position of the predetermined spot changes in accordance with the position of the detected object.

20. The image display apparatus according to claim 10, wherein

the direct-view image is a map image, and

the floating image is an image of a building, a road, a sign, or an instruction view.

21. The image display apparatus according to claim 11, wherein

the direct-view image is a map image, and

the floating image is an image of a building, a road, a sign, or an instruction view.

22. The image display apparatus according to claim 12, wherein

the direct-view image is a map image, and

the floating image is an image of a building, a road, a sign, or an instruction view.

23. The image display apparatus according to claim 10, wherein

the direct-view image is an image of a list about a predetermined item, and

the floating image is an image of detailed information or another list.

24. The image display apparatus according to claim 11, wherein

the direct-view image is an image of a list about a predetermined item, and

the floating image is an image of detailed information or another list.

25. The image display apparatus according to claim 12, wherein

the direct-view image is an image of a list about a predetermined item, and

the floating image is an image of detailed information or another list.

26. The image display apparatus according to claim 10, wherein

said image display apparatus further comprises a communicating device for communicating with another apparatus, and

said communicating device communicates with the another apparatus such that the another apparatus operates on the basis of the outputted position signal.

27. The image display apparatus according to claim 11, wherein

said image display apparatus further comprises a communicating device for communicating with another apparatus, and

said communicating device communicates with the another apparatus such that the another apparatus operates on the basis of the outputted position signal.
