Abstract

To provide a new method for displaying a video image on a whole circumference screen. Provided is an image display device including: an emission unit configured to emit image light along a predetermined axis; a screen arranged over a whole circumference around the predetermined axis and having a cylindrical shape with the predetermined axis as a substantially central axis; and an optical unit arranged to face the emission unit with the predetermined axis as a reference, and configured to control an incident angle of the image light emitted by the emission unit, the incident angle being with respect to the screen, in which a video image displayed by the image light incident on the screen is simultaneously displayed over a whole circumference around the predetermined axis.

First claim

What is claimed is:

1 . An image display device comprising:
an emission unit configured to emit image light along a predetermined axis; a screen arranged over a whole circumference around the predetermined axis and having a cylindrical shape with the predetermined axis as a substantially central axis; and an optical unit arranged to face the emission unit with the predetermined axis as a reference, and configured to control an incident angle of the image light emitted by the emission unit, the incident angle being with respect to the screen, wherein a video image displayed by the image light incident on the screen is simultaneously displayed over a whole circumference around the predetermined axis.

2 . The image display device according to claim 1 , wherein a plurality of contents is visually recognized in a superimposed manner in the video image when viewed from a predetermined direction of the screen.

3 . The image display device according to claim 1 , wherein brightness is partially adjusted in the video image.

4 . The image display device according to claim 1 , wherein the video image is continuous along a circumferential direction of the screen.

5 . The image display device according to claim 4 , wherein the video image rotates around the predetermined axis as a substantially central axis.

6 . The image display device according to claim 1 , further comprising a plurality of imaging units configured to capture an image of a user, wherein
tracking is performed on a basis of a video image captured by the plurality of imaging units.

7 . The image display device according to claim 1 , wherein the video image has an information display area having a strip shape and being continuous along a circumferential direction of the screen in an upper part of the screen.

8 . The image display device according to claim 7 , wherein the information display area slides in downward from an upper end of the screen.

9 . The image display device according to claim 7 , wherein the video image has a difference in lightness between the information display area and a region other than the information display area.

10 . The image display device according to claim 7 , wherein the information display area rotates around the predetermined axis as a substantially central axis, and a speed of the rotation changes depending on a content of information.
