DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head-mounted image display device, and more particularly to a head-mounted image display device for observing an image while being worn on a user's head.

[0002]

2. Description of the Related Art In recent years, a head-mounted image display device such as a so-called head-mounted display (HMD) has been used as a small display device for displaying and viewing images from an image reproducing device or the like or for various games. For example, various proposals have been made in, for example, Japanese Patent Publication No. Hei 8-505238.

[0003] Such a head-mounted image display device is composed of a small liquid crystal display device including a display element for displaying an image, and an image projected by the liquid crystal display device on a retina in a user's eyeball. A predetermined image display means including an optical system for projecting the liquid crystal display device, a display housing housing a drive circuit for driving the liquid crystal display device and the like, and this display housing in front of the head of the user. It is constituted by a support member provided so as to be able to support.

Japanese Patent Application Laid-Open No. 5-281506 discloses an image display device in which a device main body having a light source and a liquid crystal panel is mounted on a face, and the light source projects an image of the liquid crystal panel onto a retina. In the above image, a mounting and holding member for mounting the apparatus main body on the face is separately formed by a frame and a belt, and the mounting and holding member is detachably mounted on a side surface of the apparatus main body so as to be selectively used. A display device is described.

[0005] On the other hand, various proposals have been made for a head mounted image display device which can be used for various purposes by adding various functions to the support member and the device main body.

For example, mounting of a head mounted image display device,
Japanese Patent Application Laid-Open No. 7-1995 describes a technology for detecting non-wearing and stopping power supply to the head-mounted video display device or temporarily stopping video playback output based on the detection result.
Japanese Patent Application Laid-Open No. 294844, Japanese Patent Application Laid-Open No. 8-79658, and the like.

The technical means disclosed in Japanese Patent Application Laid-Open No. 7-294844 determines whether or not an observer is observing an image using line-of-sight information, and judges that the observer is not observing the image. Then, the power supply is cut off.

According to this technical means, the determination based on the line-of-sight information is performed by performing line-of-sight detection several times. If the line-of-sight information is detected a predetermined number of times or more, the state is set to a use state. Also, it is determined whether or not the device is worn on the head, and if not, the power supply is cut off. In addition,

In this embodiment, such a technical means is employed as the mounting / non-mounting detecting section 21.
However, the present invention is not limited to this.
Any means may be used as long as it is means for detecting that the state 6 changes between when the HMD 1 is mounted and when it is not mounted.

There are various specific examples of the attachment / non-attachment detection unit 21. These examples will be described later in detail.

Next, the operation of the head mounted image display device according to the first embodiment will be described.

First, the matching operation of the light control signal from the video reproducing device remote control unit 3 will be described.

In general, a video reproducing device 2 and a video reproducing device remote control portion 3 as a remote control portion thereof
The remote control signal transmitted and received between the remote controller and the remote controller is often unique to each model. Therefore, a unique remote control signal exists for each different model. The head mounted video display device of the present embodiment must sequentially respond to various types of remote control signals issued from the video reproduction device remote control unit 3 in order to realize such various control of the video reproduction device 2. Is possible.

That is, in accordance with the video reproducing device 2 and the video reproducing device remote control unit 3 to be used, first, an operation of copying a remote control signal transmitted and received between these devices is performed.

The user transmits a remote control signal corresponding to a predetermined operation (playback start, stop, etc.) to the HMD 1 using the video playback device remote control unit 3. In the HMD 1, the remote control signal by the optical transmission is received by the light receiving element 12 and sent to the remote control signal storage unit 13.

The remote control signal storage unit 13 is set so that a signal corresponding to a predetermined remote control signal is stored at an address designated by the CPU 11 in advance. The remote control signal of the video reproducing device 2 and the video reproducing device remote control unit 3 to be used is stored at a predetermined address. Thus, the remote control signal unique to the video player 2 is copied.

The CPU 11 reads out the corresponding remote control signal via the remote control signal reading section 14 as needed, and uses it for the control described later.

Next, the operation of the HMD 1 and the video player 2 relating to the attachment / detachment of the HMD 1 will be described with reference to FIG.

When the user wears the HMD 1 at a predetermined position on the head, the wearing / non-wearing detecting section 21 detects this (step S1), and the CPU 11 turns on the power switch 18 and thereby the entire HMD 1 Are turned on (step S2). Next, the CPU 11 controls the synchronization signal detection circuit 19 to determine the power status of the video player 2 (step S3). That is, the synchronization signal detection circuit 19 detects whether or not the synchronization signal is included in the video signal from the video player 2.

Here, if the synchronizing signal is not detected by the synchronizing signal detecting circuit 19 and the power of the video reproducing device 2 is off,
In order to turn on the power of the video reproducing device 2, the CPU 11 generates a video reproducing device power-on signal by the signal generation circuit 15 and transmits the signal to the video reproducing device 2 from the light emitting element 16 (step S4). This turns on the power of the video player 2 (step S5).

Thereafter, the CPU 11 operates the signal generation circuit 15
Is transmitted from the light emitting element 16 to the video player 2 (step S6). Thereby, the video reproducer 2 starts reproduction (step S7).

On the other hand, in step S3, when the synchronization signal can be detected by the synchronization signal detection circuit 19 and the power of the video reproducing device 2 is turned on, the CPU 11 controls the blue-back detection circuit 20 next. The playback status of the video player 2 is determined (step S8). That is, the video player 2
The blue-back detection circuit 20 detects whether or not the video signal is blue-back.

If the video signal from the video player 2 is blue-back and playback is stopped, the process proceeds to step S6, where the CPU 11 controls the signal generation circuit 15 and A playback start signal is transmitted to the video player 2.

In the above step S8, the video player 2
Is a reproduced video signal, and if the video signal is being reproduced, the process proceeds to the next step S9.

If the video player 2 has started or is playing back, the CPU 11 determines in step S9 whether the HMD 1 has changed from the mounted state to the non-mounted state, that is, whether the HMD 1 has been removed. The attachment / non-attachment detection unit 21 detects (Step S9).

Here, when the HMD 1 is detached by a signal from the attachment / non-attachment detection section 21, the CPU 11 controls the signal generation circuit 15 to send a reproduction stop signal from the light emitting element 16 to the video reproducing device 2. (Step S1)
0). This causes the video player 2 to stop playing (step S11).

Next, the CPU 11 resets the internal timer and starts operation (step S12).
Thereafter, the CPU 11 detects whether the HMD 1 has changed from the non-wearing state to the wearing state, that is, whether or not the user has worn the HMD 1 by the wearing / non-wearing detecting unit 21 (step S13).

Here, in the case of mounting, the CPU 11 stops the timer (step S18) and proceeds to step S18.
Return to 6.

On the other hand, in step S13, the HMD
If No. 1 remains unattached, the CPU 11 determines that the set timer has passed a predetermined time (step S14).
The signal generation circuit 15 is controlled to cause the light emitting element 16 to transmit a video player power-off signal to the video player 2 (step S15).

Thus, the power of the video player 2 is turned off (step S16), and then the CPU 11 turns off the power of the HMD 1 (step S17), and this routine ends. Note that even if the power of the HMD 1 is turned off, the CPU 11
Is supplied with power.

On the other hand, if the user remains wearing the HMD 1 in step S9, the CPU 11 detects a signal from the fast-forward switch 22a (step S19). Here, when the fast-forward switch 22a is off, the CPU 11 keeps the playback state of the video player 2 (step S20), and then detects a signal from the rewind switch 22b (step S21). Here, when the rewind switch 22b is also off, CP
U11 returns to step S9 while maintaining the reproduction state of the video reproducer 2 (step S22).

When the fast-forward switch 22a is on in step S19, the CPU 11 controls the signal generating circuit 15 to generate a fast-forward signal, and the light-emitting element 1
6 to the video player 2 (step S2
3). Thereby, the video player 2 performs a fast-forward operation (step S24). Thereafter, step S19 is performed again.
To detect the fast-forward switch 22a.

On the other hand, when the rewind switch 22b is turned on in step S21, the CPU 11 controls the signal generating circuit 15 to generate a rewind signal, and transmits the signal from the light emitting element 16 to the video reproducing device 2. (Step S
25). Thereby, the video player 2 performs a rewinding operation (step S26). Thereafter, the above step S1 is performed again.
9, the rewind switch 22b is detected.

As described above, according to the head-mounted video display device of the present embodiment, the control of the video player 2 (power on / off, playback start, stop, or Fast forward, rewind). This eliminates the need for an operation for attaching and detaching to and from the HMD 1, thereby providing a very convenient head-mounted image display device.

Further, after a predetermined time has elapsed after the HMD 1 has been removed, the HMD 1 and the video player 2 are automatically turned off, so that forgetting to turn off the power can be prevented.

Next, a second embodiment of the present invention will be described.
