[0001]

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

[0002]

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

FIG. 13 shows a stereoscopic image display device 1 and an observer 5.
It is a schematic diagram which showed the positional relationship with. Stereoscopic display 1
Is composed of a display unit 2 including a liquid crystal panel for displaying an image and a spectroscopic 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 separating means.

In this stereoscopic image display device 1, as shown in the figure, the regions for observing the right eye image or the left eye image alternate between the optimum observing distance (D in the figure) from the separating means 3 and its front and rear directions. Exists in. That is, the arrow range R is the right-eye image observation area, and the arrow range L is the left-eye image observation area. Therefore, when the right eye 5R of the observer 5 at the inter-eye 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 figure), the observer 5 is 5
Since an image for the right eye can be captured by R and an image for the left eye can be captured by 5L of the left eye, a stereoscopic image can be observed (normal viewing area). On the other hand, in the opposite case (the position of b in the figure), the observer 5 takes in the left-eye image with the right eye 5R and the right-eye image with the left eye 5L, and the observer 5 has stereoscopic vision. The image cannot be observed (reverse viewing area). Further, in the crosstalk area, which is an area other than the stereoscopic area and the pseudoscopic area, or the black area, the observer 5 sees a blurred image or a moire image.

[0005]

In order to observe the stereoscopic image, the observer 5 must move by himself / herself to search for a stereoscopic region (a position in the figure) where the stereoscopic image can be observed. In this case, the observer 5 cannot grasp the positions of the stereoscopic view region and the pseudoscopic view region, and at what position the observer 5 itself exists with respect to the stereoscopic view region and the pseudoscopic view region. Since it cannot be grasped, there is a problem that it takes time to find the emmetropic region.

As a method of observing a stereoscopic image in the pseudoscopic area, there is known a method of switching between the right-eye image and the left-eye image when the position of the observer 5 is in the pseudoscopic area. Has been. With this technique, the observer 5 can observe a stereoscopic image even when the position of the observer 5 is in the pseudoscopic region. However, since the observer 5 does not know the position of the stereoscopic vision region, the position of the stereoscopic vision region, and the position of the observer 5 himself, the observer 5 moves frequently and performs the stereoscopic vision region and the stereoscopic vision region. Will come and go. Therefore, the right-eye image and the left-eye image are frequently replaced with each other, which causes a problem that the displayed image flickers.

An object of the present invention is to detect the position of an observer and inform the observer of a relative positional relationship with a region where a stereoscopic image can be observed, and to suppress flickering caused by frequent switching of images. It is to provide a stereoscopic image display device.

[0008]

A stereoscopic image display device of the present invention inputs a video signal for one eye and a video signal for the other eye as a set of video signals, and forms left and right video alternately. In the stereoscopic image display device including the image forming means for displaying on the display unit and the separating means for separating and guiding the left and right images to the left and right eyes of the observer, a sensor for detecting the position of the observer, Position information generation means for generating position information relatively indicating the position of the observer and the normal viewing area or the normal viewing area and the reverse viewing area by the output from the sensor, and the position information given from the position information generating means.

According to the above configuration, since the position information indicating the stereoscopic viewing area and the position of the observer is displayed to the observer, the observer can obtain a stereoscopic image at any position. You can understand what you can observe. This allows the observer to easily move to the emmetropic region.

Further, the sensor detects the positions of a plurality of observers, and the position information generating means relatively indicates the position of the emmetropic region and the positions of the plurality of observers by the output from the sensor. To generate. It should be noted that the sensor may be composed of one or a plurality of sensors.

Further, the display means may be a display portion 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 the display screen of the display unit of the image forming means, or in this case, it may be always displayed.

The position information generating means displays the position information when the position of the observer is outside the stereoscopic viewing area, and displays the position information when the position of the observer is within the stereoscopic viewing area. You may provide the positional-information display control means which does not display. By including the position information display control means, the position information is not displayed when the observer can observe the stereoscopic image, so that the observed stereoscopic image is not shielded by the position information, and the observer can observe the stereoscopic image. Can see a good stereoscopic image. In addition, the display / non-display of the position information allows the observer to recognize that the current position of the observer himself is the emmetropic region.

Further, a first position information timekeeping means for measuring the time during which the position of the observer detected by the sensor exists outside the normal viewing area may be provided. In this case, the position information is displayed when the time measured by the first position information time measuring means has passed a predetermined time.
In addition, a second position information timekeeping unit that measures the time during which the position of the observer detected by the sensor exists in the normal viewing region may be provided. In this case, when the position information is displayed, the displayed position information is hidden when the time measured by the second position information timekeeping means exceeds a predetermined time. by this,
Even if the observer wanders on the boundary line of the emmetropic region and goes in and out of the emmetropic region, the display / non-display of the position information is not frequently switched, so that the flicker of the image on the display screen is suppressed. You can

The video signal for the one eye and the video signal for the other eye are input, and the video signal for the one or the other eye is used as the video signal for the right eye, and the other or one of the one or the other video signal is used.

This selecting means, when the position of the observer detected by the sensor is within the emmetropic region, the video signal for the one eye is a video signal for the right eye, and the video signal for the other eye. A signal is output as a video signal for the left eye, and the position of the observer detected by the sensor causes the left and right images formed by the image forming means to be guided to the left and right eyes of the observer, respectively. When it is within the area, the video signal for the one eye is output as the video signal for the right eye, and the video signal for the other eye is output as the video signal for the left eye. As a result, the observer can observe a stereoscopic image even if the position of the observer is a so-called pseudoscopic region.

Further, the first time for measuring the time during which the position of the observer detected by the sensor exists within the pseudoscopic region
A timekeeping means for selection may be provided. In this case, the selecting means sets the video signal for the one eye as the video signal for the left eye when the time measured by the first selecting timing means has passed a predetermined time, and the other eye The video signal for use as a video signal for the right eye is output to the video forming means. Further, a second selection timekeeping means for measuring the time during which the position of the observer detected by the sensor is present in the emmetropic region may be provided. At this time, the selection means sets the video signal for one eye as a video signal for the right eye when the time measured by the second selection timing means has passed a predetermined time, and the other eye And outputs the video signal for use as a video signal for the left eye to the video forming means.

By providing the first selection time measuring means and the second selection time measuring means, the observer wanders on the boundary line between the stereoscopic viewing area and the pseudoscopic viewing area and appears in the stereoscopic viewing area and the pseudoscopic viewing area. Even if it goes in and out, the selection means does not frequently switch the video signal,

A plurality of sets of video signals, one of which is the video signal for one eye and the video signal for the other eye, are input, and the plurality of video signals are input depending on the region where the observer is located detected by the sensor. A selection means for selecting one set of video signals from the set of video signals and outputting it to the video forming means may be provided. By providing the selection unit, the observer sees the position information displayed on the display unit and, for example, one emmetropic region out of a plurality of emmetropic regions provided corresponding to a plurality of sets of video signals. By moving to, the set of video signals corresponding to the stereoscopic viewing area is selected by the selecting means, and the stereoscopic image corresponding to the stereoscopic viewing area can be observed. For example, X and Y stereoscopic vision regions are arranged side by side, and in the stereoscopic vision region X, a video signal for a stereoscopic image of the front is selected,
If a video signal for the stereoscopic image on the right side surface is selected in the stereoscopic image area Y, the observer moves from within the stereoscopic image area X to within the stereoscopic image area Y by looking at the position information, and thus the stereoscopic image on the right side surface is selected. Since the video signal corresponding to is selected by the selecting means, the observer can observe the stereoscopic image on the right side surface. As a result, the observer can observe the stereoscopic image at the desired position by looking at the position information and moving.

Further, it may be provided with a clocking means for selection for measuring a time during which the position of the observer detected by the sensor is present in the area. The selecting means selects the one set of video signals from the plurality of sets of video signals and outputs the video signals to the video forming means when the 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 goes in and out of the area, the selection means does not frequently change the video signal to be selected, so that the image is frequently displayed. It is possible to suppress the flickering of the image on the display screen without switching.

As a display method, the observation position may be displayed on the map when the observation position of the observer moves by a certain area or a certain distance.

Further, although the map is displayed directly on the display screen of the display unit 26, a display unit is provided separately from the display screen of the display unit 26, and the position of the observer and the normal viewing area and the reverse vision are provided. The relative positional relationship with the area 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 the normal-viewing region and the reverse-viewing region, which are 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 determined. The observer may be informed of the observation position by lighting the light emitting diode or the like depending on the position of 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 of the display unit 26, it is possible to prevent the image displayed on the display screen from being shielded or prevent the area where the image is displayed from eroding.

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

By displaying the position information when the position of the observer does not exist within the stereoscopically viewable area,
Since the stereoscopic image observed by the observer is not blocked by the position information, the observer can observe a good stereoscopic image. Further, by displaying the position information after a lapse of a predetermined time from the position of the observer outside the stereoscopic viewable area, it is possible to prevent flickering of the image due to frequent switching of display / non-display of the position information. be able to. In addition,
The same effect can be obtained when the selecting means selects a set of video signals according to the region where the position of the observer exists and outputs the video signals to the video forming means to switch the video.
