Abstract

There is provided an excellent image display device allowing observation of a surrounding scene by a video see-through method. While an authentication process is being performed, a head-mounted display 100 superimposes, and displays, an authentication screen on a video see-through image captured by an outside camera 312. Accordingly, a user is enabled to observe the surrounding scene by the video see-through image during the authentication process. Even when using the head-mounted display 100 while walking outdoors, the user is enabled to constantly grasp his/her surroundings, and the safety may be secured.

Claims

1. An image display device comprising:

a display unit to be used by being mounted on a head or a face of a user;

a detection unit for detecting whether the display unit is mounted on the head or the face of the user;

a capturing unit for capturing surroundings; and

a control unit for controlling an image to be displayed on a screen at the display unit,

wherein the control unit causes the display unit to display a captured image of the capturing unit, in response to detection, by the detection unit, of mounting of the display unit on the head or the face of the user.

2. The image display device according to claim 1, wherein the control unit switches the display unit from a non-display state to display of the captured image, in response to detection, by the detection unit, of mounting of the display unit on the head or the face of the user.

3. The image display device according to claim 1, further comprising an authentication processing unit for performing authentication of the user.

4. The image display device according to claim 3, wherein the authentication processing unit displays an authentication screen on the captured image, in response to detection, by the detection unit, of mounting of the display unit on the head or the face of the user.

7. The image display device according to claim 1, further comprising a content acquisition unit for acquiring content,

wherein the control unit switches display on the display unit from the captured image to a content reproduction image, in response to occurrence of a predetermined event.

5. An image display device comprising:

a display unit to be used by being mounted on a head or a face of a user;

a detection unit for detecting whether the display unit is mounted on the head or the face of the user;

a capturing unit for capturing surroundings;

an authentication processing unit for performing authentication of the user; and

a control unit for controlling an image to be displayed on a screen at the display unit,

wherein the control unit displays an authentication screen on a captured image of the capturing unit during authentication processing by the authentication processing unit.

6. The image display device according to claim 5, wherein the authentication processing unit erases the authentication screen in response to completion of authentication processing.

8. An image display method comprising the steps of:

detecting whether a display unit to be used by being mounted on a head or a face of a user is mounted on the head or the face of the user;

acquiring a captured image of surroundings of the user; and

causing the display unit to display the captured image, in response to detection of mounting of the display unit on the head or the face of the user.

9. An image display method comprising the steps of:

detecting whether a display unit to be used by being mounted on a head or a face of a user is mounted on the head or the face of the user;

acquiring a captured image of surroundings of the user; and

performing authentication of the user by displaying an authentication screen on the captured image.

10. A computer program described in a computer-readable form, the computer program being for causing a computer to function as:

a detection unit for detecting whether a display unit to be used by being mounted on a head or a face of a user is mounted on the head or the face of the user;

an image acquisition unit for acquiring a captured image of surroundings of the user; and

a display unit for causing the display unit to display the captured image, in response to detection of mounting of the display unit on the head or the face of the user.

11. A computer program described in a computer-readable form, the computer program being for causing a computer to function as:

a detection unit for detecting whether a display unit to be used by being mounted on a head or a face of a user is mounted on the head or the face of the user;

an image acquisition unit for acquiring a captured image of surroundings of the user; and

an authentication processing unit for performing authentication of the user by displaying an authentication screen on the captured image.
