Transmit to the sensor 18. On the other hand, when the observer 24 removes the glasses 12, the push switch 22 is turned off, and the light emission of the light emission sensor 16 stops. Thus, the presence or absence of wearing of the glasses 12 is notified by the presence or absence of light emission of the light emission sensor 16.

The light receiving sensor 18 is formed of, for example, a photodiode, and is formed on the upper surface of the monitor 14, for example. Further, as shown in FIG. 4, the monitor 14 includes a video processing circuit 26 and a video selection circuit 28.

A stereoscopic video is input to the monitor 14, and the stereoscopic video is directly supplied to a video selection circuit 28 as it is. The video processing circuit 26 converts the stereoscopic video into a 2D video and supplies it to the video selection circuit 28. . Video selection circuit 2
8 selects an image in response to a signal from the light receiving sensor 18, that is, whether or not the light receiving sensor 18 has detected light from the light emitting sensor 16. If the light receiving sensor 18 detects light from the light emitting sensor 16, the observer 24
Is selected, a stereoscopic image is selected, and if the light receiving sensor 18 does not detect light, the observer 24
2 is not attached, and a conventional 2D image is selected. Here, the 2D image may be only the right-eye image or the left-eye image, or may be an image created by synthesizing them, or may be a message such as “wear glasses”. .

The image selected in this way is displayed on the monitor 14. If the observer 24 wears the glasses 12, a stereoscopic image is displayed. If the observer 24 does not wear the glasses 12, a 2D image is displayed. , Each can be observed.

Therefore, according to the three-dimensional display device 10,

The monitor 14 may be configured as shown in FIG.

The monitor 14 shown in FIG.
The video selection circuit 28 supplies the stereoscopic video to the video processing circuit 26 only when the photodetector 8 receives the signal of wearing no glasses, that is, when the light receiving sensor 18 cannot detect the light from the light emission sensor 16, and outputs the 2D video. It is displayed on the monitor 14.

The stereoscopic display device 1 according to the above-described embodiment
0 can be similarly applied to a deflecting spectacle system using deflecting spectacles for the spectacles 12 and a color spectacle system using color spectacles for the spectacles 12.

Furthermore, in the three-dimensional display device 10, the push switch 22 is configured to be pushed by the forehead of the observer 24. It may be pushed by a part or by hand. In this case, the glasses 12 may be any of liquid crystal shutter glasses, deflection glasses, and colored glasses.

Referring to FIG. 6, a three-dimensional display device 10a according to another embodiment uses liquid crystal shutter glasses 12a having a shutter power switch 30 as glasses, and other components such as a monitor 14. Is a stereoscopic display device 1
Same as 0.

The liquid crystal shutter glasses 12a have a shutter power supply (not shown) for controlling the opening / closing operation of the liquid crystal shutter 32. The power supply from the shutter power supply to the liquid crystal shutter 32 is controlled by a shutter power supply switch 30. Is done.

It should be noted here that the shutter power switch 30 also has a function of controlling the light emission operation of the light emission sensor 16. That is, when the shutter power switch 30 is turned on, the light emission sensor 1 is turned on.
6 emits light, and the light emission sensor 16 stops emitting light when the shutter power switch 30 is turned off.

When the light from the light emission sensor 16 is detected by the light receiving sensor 18 formed on the monitor 14, it is determined that the observer 24 is wearing the liquid crystal shutter glasses 12a. Select a stereoscopic image. On the other hand, the light from the light emission sensor 16 is
Is not detected, the observer 24 moves the liquid crystal shutter glasses 12
a is not attached, and the video selection circuit 28
Select a video.

According to the three-dimensional display device 10a, the observer 24
The observer 24 can normally recognize the image and does not feel uncomfortable not only when the user wears the liquid crystal shutter glasses 12a but also when the user does not wear the liquid crystal shutter glasses 12a. Further, since the shutter power switch 30 can also be used as the input means, it is possible to easily and surely display an image according to the presence or absence of spectacles without separately increasing the number of components.

Referring to FIG. 7, a stereoscopic display device 10b according to another embodiment includes glasses 12b and a monitor 1b.
4b, the glasses 12b have a reflection plate 34, and the monitor 14 has a light emission sensor 36 and a light reception sensor 38, respectively. Note that the glasses 12b may be any of liquid crystal shutter glasses, deflection glasses, and colored glasses.

The reflection plate 34 is formed, for example, substantially at the center of the upper edge of the frame 20b of the glasses 12b. In addition, the light-emitting sensor 36 and the light-receiving sensor 38 are formed, for example, substantially at the center of the upper surface of the monitor 14b. The light emission by the light emission sensor 36 may be performed by turning on a power switch of the monitor 14b or a light emission switch (not shown) of the light emission sensor 36. The light emission sensor 36 always emits light. May be.

In the stereoscopic display device 10b, when the observer 24 is wearing the glasses 12b and looking at the monitor 14b,
The light from the light emitting sensor 36 strikes the reflecting plate 34 and is reflected and detected by the light receiving sensor 38.
A stereoscopic video is displayed on 4b. On the other hand, when the observer 24 does not wear the spectacles 12b, the light from the light emission sensor 36 is not normally reflected by the reflection plate 34, and the light reception sensor 38
Does not detect the light, a 2D image is displayed on the monitor 14b.

In such a stereoscopic display device 10b, not only when the observer 24 wears the glasses 12b,
Even when the spectacles 12b are not worn, the observer 24 can normally recognize the video and does not feel discomfort. In addition, since nothing other than the reflection plate 34 is required as a component of the detecting means on the side of the glasses 12b, a stereoscopic image can be observed using the glasses 12b that are lightweight and have a good feeling of wearing.

The reflector 34 polarizes the incident light,
Accordingly, it is more preferable that the light receiving sensor 38 also detects only the polarized light. With this configuration, it is possible to prevent a malfunction caused by the light from the light emitting sensor 36 being reflected by a member other than the reflecting plate 34 and being detected by the light receiving sensor 38.

Further, in the stereoscopic display device 10 shown in FIG. 1, instead of the glasses 12 using the push switch 22, glasses 12c as shown in FIG. 8 may be used.

In the spectacles 12c, a light emitting sensor 40 and a light receiving sensor 42 are formed on the back surface of the frame 20c, that is, on the observer 24 side.

When the observer 24 wears the glasses 12c, the light from the light emission sensor 40 is, for example, the observer 24
And is detected by the light receiving sensor 42. Then
In response to a signal indicating wearing of glasses from the light receiving sensor 42, the light emitting sensor 16 formed at the approximate center of the upper edge of the frame 20c of the glasses 12c emits light. Selects a stereoscopic image, and the monitor 14 displays the stereoscopic image.

On the other hand, when the observer 24 does not wear the glasses 12c, the light receiving sensor 42 does not detect the light from the light emitting sensor 40. Then, since the signal indicating wearing of glasses is not output from the light receiving sensor 42, the light emitting sensor 16 does not emit light, the image selection circuit 28 selects a 2D image, and the monitor 14 displays the 2D image.

Therefore, according to the stereoscopic display device 10 using the spectacles 12c, the observer 24 can display images not only when the spectacles 12c are worn, but also when the spectacles 12c are not worn. It can be recognized normally and does not cause discomfort. In addition, since the light is emitted toward, for example, the forehead of the observer 24 at a close distance from the glasses 12c, the presence or absence of the glasses is determined, so that not only the image corresponding to the presence or absence of the glasses can be accurately displayed, but also a separate reflecting member is provided. There is no need, and the device can be simplified.

When the spectacles 12c shown in FIG. 8 are used, the reason why the reflector is not used is that, in this case, the reflector (the forehead of the observer 24) is located very close to the spectacles 12c. This is because the light receiving sensor 42 can detect light even without the light.

On the other hand, the stereoscopic display device 10 shown in FIG.
In b, since the reflector (object) is far away, the reflector 3
4 is used.

Further, the stereoscopic display device may be configured by connecting glasses and a monitor with a connection cord. In this case, the glasses are provided with a push switch for notifying wearing of the glasses and a power supply for supplying an electric signal to the monitor via the connection cord.

In such a stereoscopic display device, when the observer wears the glasses and presses the push switch, an electric signal indicating the wearing of the glasses is given to the monitor via the connection cord.
A stereoscopic image is displayed on the monitor. On the other hand, if the push switch is not pressed and an electric signal indicating that the glasses are not worn is given to the monitor, a 2D image is displayed on the monitor.

In the above-described embodiment, the detection means for detecting the presence / absence of spectacles is described as being included in the spectacles or the monitor, but is not limited to this. For example, a detection unit for detecting whether or not the glasses are worn may be provided at an arbitrary place other than the glasses or the monitor.

The signal indicating the presence or absence of wearing glasses is not limited to light, and any signal can be used, and the transmitting means and the receiving means are appropriately configured accordingly.

FIG. 3 shows an example of the electrical configuration of the light-emitting sensor and the light-receiving sensor, and any electrical configuration can be applied as long as the presence or absence of spectacles can be transmitted to the monitor. .

When the observer 24 does not wear glasses, the monitor may display any video other than the stereoscopic video, not limited to the 2D video, and may not display the video. You may do so.

[0059]

According to the three-dimensional display device of the present invention, the image to be displayed is switched depending on whether or not the observer wears spectacles. The person can recognize the image normally and does not feel discomfort.

That is, when the observer wears spectacles, a predetermined stereoscopic image is displayed, and when the observer does not wear spectacles, an image other than the stereoscopic image is displayed.
Not only when the observer wears spectacles but also when the observer does not wear spectacles, the observer can recognize the video normally and does not feel discomfort.

Further, by inputting information on whether or not the spectacles are worn from the input means, it is possible to accurately display an image according to the presence or absence of the spectacles.
