Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-view stereoscopic image display device which uses a pair of shutter glasses to enable stereoscopic viewing of an image projected on a display device. The present invention relates to a multi-view three-dimensional imaging display device that enables a viewer to enjoy a natural three-dimensional image even when viewed from a direction.

[0002]

2. Description of the Related Art A stereoscopic display system that enables stereoscopic viewing of an image projected on a display device is known. It can be broadly classified into three types: an eye system, a binocular parallax, a motion parallax, and a volume display system for reproducing focus adjustment.

[0003] Among them, the binocular parallax method is the one that can obtain a stereoscopic effect most easily, and this method is called a stereogram that inputs a left-eye image and a right-eye image having different parallax between the left and right eyes. The stereoscopic television adopting the binocular parallax method includes, for example, a display device that alternately displays a left-eye image and a right-eye image, and a left-eye image and a right-eye image, respectively, of a viewer who views the left and right images. It is combined with shutter glasses provided with left-eye and right-eye shutters that open and close alternately so as to be seen by the eyes.

On the other hand, the multi-view system uses a parallax barrier or a lenticular lens, and allows viewing of a stereoscopic image without glasses.

Then, as shown in FIG. 3B, the shutter glasses 20 worn by the person watching in the area 1 receive the timing signal 1 at the time t1, and the receiving section 23 receives the timing signal 1. The shutter 25 for the left eye is at time t1
From t2 to t2. At time t2, the shutter 25 for the left eye is closed and at the same time the shutter 26 for the right eye is
Open from 2 to t3. Therefore, a person watching in the area 1 sees the image 1 projected on the display device 10 only with the left eye while the shutter 25 for the left eye is open, and opens the shutter 26 for the right eye. Since the image 2 projected on the display device 10 is viewed only by the right eye during the display, the stereoscopic video of the subject 9 viewed from the left can be watched.

The shutter glasses 20 worn by the person watching in the areas 2 and 3 are shown in FIGS. 2 (c) and 2 (d).
As shown in (5), since the receiving unit 23 does not receive the timing signal 1 at the time t1, the shutter 25 for the left eye does not open at the time t1, and the shutter 26 for the right eye does not open at the time t2. Therefore, those who watch in the area 2 and the area 3 can be viewed from the time t1 to the time t3.
, The images 1 and 2 are not viewed.

As shown in FIG. 2C, the shutter glasses 20 worn by the person watching in the area 2 are at time t.
2, the receiving unit 23 receives the timing signal 2 so that the shutter 25 for the left eye is opened from time t2 to t3, and the shutter 25 for the left eye is closed at the time t3 and the shutter 26 for the right eye is simultaneously operated at the time t2. t3 to t
Open to 4. A person watching in the area 2 views the image 2 displayed on the display device 10 only while the left-eye shutter 25 is open, and the right-eye shutter 26 is open. By watching the image 3 projected on the display device 10 only during the period,
It is possible to watch a stereoscopic image of the subject 9 viewed from the front.

Since the shutter glasses 20 worn by the person watching in the areas 1 and 3 do not receive the timing signal 2 at time t2, the shutter 25 for the left eye does not open at time t2, The shutter 26 for the right eye does not open at time t3. Therefore, those who are watching in the area 1 and the area 3 can be viewed from the time t3 to the time t4.
, Images 2 and 3 are not viewed.

As shown in FIG. 2D, the shutter glasses 20 worn by the person watching in the area 3 are at time t.
At 3, the reception unit 23 receives the timing signal 3, so that the left-eye shutter 25 is opened from time t3 to t3, and is closed at time t3, and at the same time, the right-eye shutter 26 is opened from time t4 to t5. Become. Then, the person watching in the area 3 is the shutter 2 for the left eye.
By viewing the image 3 projected on the display device 10 only while the shutter 5 is open, and viewing the image 4 projected on the display device 10 only while the shutter 26 for the right eye is open, A three-dimensional image of the subject 9 viewed from the right can be watched.

Thereafter, at time t5, the receiving unit 23 receives the timing signal 1 at the time t5, and the shutter glasses 20 worn by the person watching in the area 1 are worn by the person watching in the area 2. Shutter glasses 20 at time t6

The user can watch a natural stereoscopic image as if the subject 9 is viewed from the direction facing the display device 10.

Next, a case in which the viewer is watching in the boundary area between the area 1 and the area 2 will be described. In such a boundary region, the receiving unit 23 of the shutter glasses 20 receives both the timing signal 1 and the timing signal 2. However, since the receiving unit 23 receives the timing signal 1, the control unit 24 does not open the shutter 25 for the left eye even when receiving the timing signal 2. Therefore, for example, if the receiving unit 23 of the shutter glasses 20 receives the timing signal 1 at the time t1, as shown in FIG. 2B, the shutter 25 for the left eye is opened for a predetermined time from the time t1 to the time t2, for example. Thus, even if the timing signal 2 is received at the time t2, the shutter 25 for the left eye is closed and the shutter 26 for the right eye is opened for a predetermined time from the time t2 to t3. Since the shutter signal 1 has a higher priority than the shutter signal 2 as described above, a malfunction due to crosstalk does not occur, and a person watching in the boundary area between the area 1 and the area 2 can view the images 1 and 2 visually. And
You can watch stereoscopic images.

When entering the boundary area between area 1 and area 2 between
Since the receiving unit 23 does not receive the timing signal 1, by receiving the timing signal 2, as shown in FIG. 2C, the left-eye shutter 25 is opened for a predetermined time from time t2 to time t3, At time t3, the shutter 25 for the left eye closes and the shutter 26 for the right eye simultaneously.
Open for a predetermined time from time t3 to t4. In this way, a person watching in the boundary region between the region 1 and the region 2 can view the images 2 and 3 and view a natural stereoscopic image. In the boundary region between the region 1 and the region 2, the viewer does not feel an unnatural stereoscopic image even if the stereoscopic image is viewed from the left side or the stereoscopic image viewed from the front.

Similarly, in the boundary area between the area 2 and the area 3, the shutter 25 for the left eye and the shutter 26 for the right eye open and close in a time series for a predetermined time in response to one of the timing signals 2 and 3. 3, or images 3 and 4 can be viewed and a stereoscopic image viewed from the front or right side can be viewed.
