DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereoscopic video display device capable of observing a stereoscopic video without using special glasses.

[0002]

2. Description of the Related Art Conventionally, as an apparatus for displaying a stereoscopic image without using special glasses, a parallax barrier, a lenticular lens, and the like (separating means) are arranged on a viewer side of a display screen of a display panel such as a liquid crystal panel. Then, the light from the left-eye image and the right-eye image displayed on the display panel is separated into right and left, and the stereoscopic image is recognized by the observer using the binocular parallax of the observer. Are known.

FIG. 13 shows a three-dimensional image display device 1 and an observer 5.
FIG. 3 is a schematic diagram showing a positional relationship between the two. 3D display device 1
Is composed of a display unit 2 including a liquid crystal panel for displaying an image and a spectral unit 3 including a parallax barrier or a lenticular lens. The image displayed on the display unit 2 is separated into a right-eye image and a left-eye image by the separation unit.

In the three-dimensional image display device 1, as shown in the figure, an optimum observation distance (D in the figure) from the separating means 3 and an area where a right-eye image or a left-eye image can be observed are alternately arranged in the vicinity of the optimum distance. Exists. That is, the arrowed range R is a right-eye image observation region, and the arrowed range L is a left-eye image observation region. Therefore, in the case where the right eye 5R of the observer 5 at the interocular distance E is in the right-eye image observation region and the left eye 5L is in the left-eye image observation region (position a in the drawing), the observer 5 does not use the right eye. 5
Since a video for the right eye can be captured by R and a video for the left eye by the left eye 5L, a stereoscopic image can be observed (standard viewing area). On the other hand, in the opposite case (the position b in the figure), the observer 5 takes the left-eye image with the right eye 5R and the right-eye image with the left eye 5L, resulting in stereopsis. The image cannot be observed (reverse viewing area). In a crosstalk area other than the normal viewing area and the reverse viewing area, or in a black area, the observer 5 sees a blurred image or a moiré image.

[0005]

In order to observe a stereoscopic image, the observer 5 needs to move and search for a standard viewing area (position a in the figure) where the stereoscopic image can be observed. In this case, the observer 5 does not know the positions of the normal viewing region and the reverse viewing region, and also indicates the position of the observer 5 itself with respect to the normal viewing region and the reverse viewing region. Since it has not been grasped, there is a problem that it takes time and effort to find the emmetropic region.

[0006] As a technique for observing a stereoscopic image in the pseudoscopic region, a method of switching between a right-eye image and a left-eye image when the position of the observer 5 is in the pseudoscopic region is known. Have been. With this technique, the observer 5 can observe a stereoscopic image even when the position of the observer 5 is in the reverse viewing area. However, since the observer 5 cannot grasp the position of the normal viewing area, the position of the reverse viewing area, and the position of the observer 5 itself, the observer 5 moves frequently, and performs the reverse viewing area and the normal viewing area. Will come and go. Therefore, there arises a problem that the right-eye image and the left-eye image frequently alternate with each other, and flicker occurs in the displayed image.

SUMMARY OF THE INVENTION It is an object of the present invention to detect a position of an observer and notify the observer of a relative positional relationship with a region where a stereoscopic image can be observed, and to suppress flicker caused by frequent switching of images. It is to provide a stereoscopic video display device.

You can see if you can observe. Thereby, the observer can easily move to the standard viewing area.

Further, the sensor detects the positions of a plurality of observers, and the position information generating means outputs position information indicating the position of the plurality of observers relative to the emmetropic region based on an output from the sensor. Generate In addition, the sensor may be constituted by one, or may be formed by a plurality.

The display means may be constituted by a display unit of the image forming means. In this case, the position information may be selectively displayed on the entire display screen of the display unit of the image forming unit. Further, the position information may be displayed on a part of a display screen of a display unit of the image forming unit, and may be always displayed in this case.

The position information generating means displays the position information when the position of the observer is outside the normal viewing area, and displays the position information when the position of the observer is within the normal view area. May be provided. By providing this position information display control means, when the observer can observe the stereoscopic image, the position information is not displayed, so that the observed stereoscopic image is not blocked by the position information, Can observe a good three-dimensional image. In addition, the display / non-display of the position information allows the observer to know that the current position of the observer is in the normal viewing area.

[0013] Further, there may be provided a first position information timing means for measuring a time during which the position of the observer detected by the sensor is outside the normal viewing area. In this case, the position information is displayed when the time measured by the first position information timer has passed a predetermined time.

[0016] By providing the first selection timing means and the second selection timing means, an observer fluctuates on the boundary line between the normal viewing area and the reverse viewing area, and goes out to the normal viewing area and the reverse viewing area. Even when entering or leaving, since the selection means does not frequently switch the video signal,
The image on the display screen does not change frequently, and flickering of the image on the display screen can be suppressed.

[0017] A plurality of sets of video signals, each of which is a set of the video signal for one eye and the video signal for the other eye, are input, and the plurality of video signals are set according to the region where the observer is detected by the sensor.

By providing the selection unit, the observer sees the position information displayed on the display unit, and for example, one of the plurality of stereoscopic regions provided corresponding to a plurality of sets of video signals. , A set of video signals corresponding to the emmetropic region is selected by the selecting means, and a stereoscopic image corresponding to the emmetropic region can be observed. For example, X and Y standard viewing regions are arranged side by side, and in the standard viewing region X, a video signal for a front stereoscopic image is selected,
Assuming that a video signal for the right-side stereoscopic image is selected in the right-view region Y, the observer moves from the right-view region X to the right-view region Y by looking at the position information, and thereby the right-view stereo image is selected. Is selected by the selection means, so that the observer can observe a stereoscopic image on the right side. Thus, the observer can observe a stereoscopic image at a desired position by moving while viewing the position information.

[0018] The information processing apparatus may further include a selection time measuring means for measuring a time during which the position of the observer detected by the sensor is present in the area. The selection means selects the set of video signals from the plurality of sets of video signals and outputs the selected set of video signals to the video formation means when a time measured by the selection timing means has passed a predetermined time. By providing the selection timing means, even when the observer wanders on the boundary line of the area and enters or leaves the area, the selection means does not frequently change the video signal to be selected. Without switching, flickering of the image on the display screen can be suppressed.

Alternatively, the display / non-display of the map 130 or the selection operation of the video signal may be performed after a predetermined time has elapsed in the area.

As a method of displaying the map in the first to sixth embodiments by the observer, there is a method of sequentially displaying the observation position on the map in response to the movement of the observation position of the observer. By displaying with this display method, the observer can accurately grasp the current observation position, and also can accurately grasp the positional relationship between the current observation position and the normal viewing area and the reverse viewing area, and It can also be an indicator. As a display method, when the observation position of the observer moves by a certain area or a certain distance, the observation position may be displayed on a map.

Further, the map is displayed directly on the display screen of the display unit 26. However, a display unit is provided separately from the display screen of the display unit 26 so that the position of the observer, the normal viewing area, and the reverse viewing The relative positional relationship with the region may be displayed to the observer. For example, a device in which light-emitting diodes and the like are formed so as to correspond to a normal viewing region and a reverse viewing region alternately formed in the horizontal direction of the screen is provided separately from the display unit 26, and the observation position of the observer is different. The observation position may be notified to the observer by lighting the light emitting diode or the like depending on the position in the region. With this configuration, it is not possible to sequentially display the observation position according to the movement of the observation position of the observer, and to display the observation position of the observer moved in the vertical direction of the screen,
Since the map is not displayed on the display screen on the display unit 26, it is possible to block an image displayed on the display screen and prevent erosion of an area where the image is displayed.

According to the above arrangement, the observer can grasp the relative positional relationship between the observer's position and the stereoscopically viewable area by looking at the position information displayed on the display means. Also, even when the observer is not located in the stereoscopically viewable area, the observer can easily move to the stereoscopically viewable area.

Also, by displaying the position information when the position of the observer does not exist in the stereoscopically viewable area,
Since the three-dimensional image observed by the observer is not obstructed by the positional information, the observer can observe a favorable three-dimensional image. Further, by displaying the position information after a lapse of a predetermined time after the position of the observer is outside the stereoscopically viewable area, flickering of an image due to frequent switching of display / non-display of the position information is prevented. be able to. In addition,
The same effect is obtained in a case where the selecting means selects a set of video signals according to the area where the position of the observer is present, and outputs to the video forming means to switch the video.
