Abstract

An image display system includes a camera that shoots a background, a monitor that displays a shot background image, and an optical lens arranged between a display surface of the monitor and an observer. An imaginary image, obtained due to presence of the optical lens, of the monitor image is made to substantially match with a background surface. As a result, when the observer views the background through the monitor, the monitor image and the background look continuous to him.

Claims

1-13. -13. (canceled)

14. An image display system that causes an observer to recognize that a monitor image and a background look continuous, the image display system comprising:

a monitor that displays a shot background image; and

an optical lens that is arranged between a display surface of the monitor and the observer, wherein an imaginary image, obtained due to presence of the optical lens, of the monitor image is made to substantially match with a background surface.

15. The image display system according to claim 14, wherein a distance d between the monitor and the optical lens satisfies following Expression (X1)

16. The image display system according to claim 15, further comprising:

a distance measuring unit that measures the distance l between the monitor and the background surface; and

a distance adjustment mechanism that adjusts the distance d between the monitor and the optical lens, wherein the distance adjustment mechanism adjusts the distance d by using Expression (X1) based on the distance l between the monitor and the background surface measured by the distance measuring unit.

17. The image display system according to claim 14, wherein a magnification Mg of the background image displayed on the monitor satisfies following Expression (X2)

18. The image display system according to claim 17, further comprising:

a distance measuring unit that measures the distance 1 between the monitor and the background surface; and

a display-size converting unit that converts the magnification Mg of the background image displayed on the monitor, wherein the display-size converting unit converts the magnification Mg by using Expression (X2) based on the distance l between the monitor and the background surface measured by the distance measuring unit.

19. The image display system according to claim 14, wherein a lens size r measured from an optical axis of the optical lens in a predetermined direction satisfies following

20. The image display system according to claim 14, wherein a power φ

or a focal distance f of the optical lens satisfies following Expression (X4)

21. The image display system according to claim 14, further comprising a combined-image generating unit that generates a combined image by combining an additional image with the background image, wherein

the monitor displays the combined image.

22. The image display system according to claim 14, further comprising a camera that shoots the background.

23. The image display system according to claim 22, wherein the camera is arranged on the background surface of the monitor.

24. The image display system according to claim 22, wherein the camera is arranged on a shielding object placed between the monitor and the background.

25. The image display system according to claim 22, wherein the camera is a multi-lens camera, and the image display system further comprises a viewpoint-converted-image generating unit that generates an observer'"'"'s viewpoint-based background image based on a plurality of background images shot by the multi-lens camera.

26. An image display method that causes an observer to recognize that a monitor image and a background look continuous, the image display method comprising:

a step of shooting the background; and

a step of displaying a shot background image on a display surface of the monitor at which an optical lens is arranged, wherein an imaginary image, obtained due to presence of the optical lens, of the monitor image is made to substantially match with a background surface.
