An image display module displaying a plurality of views to display a stereoscopic image; And providing first and second views included in the plurality of views as a left eye image and a right eye image of a viewer viewing the stereoscopic image, respectively, and when a reversed stereoscopic image is generated by the first and second views, 1 and the second view.

Description

TECHNICAL FIELD [0001] The present invention relates to a stereoscopic image display device,

The present invention relates to a stereoscopic image display device, and more particularly, to a stereoscopic image display device and a driving method thereof that can prevent the generation of an inverse stereoscopic image independently of a viewing position.

The stereoscopic (or 3D) image display device is a device that enables a viewer to view a stereoscopic image by binocular parallax between the left and right eyes by providing different images to the left and right eyes of a viewer.

In recent years, studies have been actively conducted on the non-eyeglass system in which stereoscopic glasses are not worn. In the non-eyeglass system, there is a lenticular system for separating the left eye and right eye images using a cylindrical lens array, and a barrier system for separating the left eye and the right eye image using a barrier.

1 is a schematic view for explaining a general barrier type stereoscopic image display apparatus.

1, a conventional barrier type stereoscopic image display apparatus includes a display panel 110 for displaying the left eye image L and the right eye image R in a separated manner, and a display panel 110 disposed on the front surface of the display panel 110, And a barrier panel 120 for alternately forming the region 122 and the light blocking region 124. [

The viewer 130 views the image displayed on the display panel 110 through the light transmitting region 122 of the barrier panel 120. The left eye and the right eye of the viewer 130 have the same light transmitting region 122 The user can see another area of the display panel 110 through the display area. Accordingly, the viewer 130 views the left-eye image L and the right-eye image R, which are displayed adjacently through the light-transmitting region 122, to feel the three-dimensional effect.

Such a general barrier type stereoscopic image display device can be switched between a flat image display mode or a stereoscopic image display mode depending on the states of the light transmitting region 122 and the light blocking region 124 formed in the barrier panel 120 There are advantages. Due to these advantages, it has recently been applied to televisions, monitors, notebook computers, netbook computers, tablet computers, and mobile devices.

However, since the aperture ratio of the light transmitting area 122 and the light blocking area 124 formed in the barrier panel 120 is fixed based on the optimum viewing distance r, in a general barrier type three-dimensional image display device, There is a problem that the viewer 130 can not view the stereoscopic image due to the 3D crosstalk generated by mixing the left eye image and the right eye image according to the change of the distance or the viewing position, or the user feels dizziness.

For example, the viewer 130a located in the regular time zone can view the left eye image L in the left eye and the right eye image R in the right eye to view a clear stereoscopic image. However, the viewers 130b and 130c located in the area can also have a reverse image or a reversed image in which the right eye image R is viewed in the left eye and the left eye image L is viewed in the right eye.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a stereoscopic image display device and a method of driving the stereoscopic image display device, which can reduce the heterogeneity of a stereoscopic image even when the viewer is out of the regular time zone.

Hereinafter, a stereoscopic image display device according to an embodiment of the present invention will be described in a barrier manner for convenience of explanation. However, the present invention is not limited to a barrier type stereoscopic image display apparatus, and can be applied to all stereoscopic image display apparatuses of a non-spectacle type as well as a stereoscopic image display apparatus using a lenticular system.

FIG. 2 is a view schematically showing a stereoscopic image display apparatus according to an embodiment of the present invention, and FIG. 3 is a block diagram schematically showing a stereoscopic image display apparatus according to an embodiment of the present invention.

2 and 3, the stereoscopic image display apparatus 200 according to an exemplary embodiment of the present invention includes an image display module 220 and an image display module 220 for displaying a stereoscopic image including a plurality of views And a control module 300 for controlling the displayed image. In one embodiment, the stereoscopic image display apparatus 200 may further include a camera module 210 for capturing an image of a viewer 230 viewing a stereoscopic image.

First, the image display module 220 can display a stereoscopic image including a plurality of views. Here, the plurality of views may include a view set made up of n (n > 2 natural number) parallax images.

The image display module 220 is capable of converting a flat (or 2D) image display mode and a stereoscopic (or 3D) image display mode and displays a predetermined flat image according to the flat image display mode, And displays them alternately on one screen.

For example, the image display module 220 can realize a stereoscopic image by using a plurality of views passing through the light transmission region by alternately forming the light transmission region and the light blocking region. At this time, it is preferable that the light transmitting region is an area through which the view displayed on the unit pixel is transmitted to the outside, and the central portion of the light transmitting region overlaps the center portion of the unit pixel. The light blocking area is for preventing blending of views displayed in adjacent unit pixels, and the central part of the light blocking area is preferably overlapped with a boundary part of adjacent unit pixels.

Next, the camera module 210 images the viewer 230 viewing the stereoscopic image displayed on the image display module 220 in the stereoscopic image display mode, and provides the captured viewer image to the control module 300.

Next, the control module 300 controls the image displayed on the image display module 220. The control module 300 may be implemented as a central processing unit (CPU), a micro control unit (MCU), or a video processing module when the stereoscopic image display apparatus 200 is a notebook computer, a netbook computer, a tablet computer, A video processing module such as a scaler or a video card, or a micro control unit (MCU) when the stereoscopic image display device 200 is a television or a monitor.

3, the control module 300 includes an inverse object determining unit 340, an image correcting unit 350, and an image processing unit 360. [ The control module 320 may further include at least one of the position obtaining unit 310, the time zone determining unit 330, the timer 370, and the warning notifying unit 380. [

The position acquiring unit 310 acquires the position of the viewer 230 by analyzing the viewer image provided from the camera module 210. For example, the position obtaining unit 310 may detect the left and right eyes of the viewer in the viewer image, and may calculate the distance of the viewer 230 using the distance between the detected left and right eyes. The position obtaining unit 310 can specify the position of the viewer 230 using the distance of the calculated viewer 230 and the coordinate information of the left and right eyes on the viewer image.

In one embodiment, the position obtaining unit 310 controls the camera module 210 according to an eye tracking method to follow a change in position of any one of the eyes, eyeballs, and eyebrows of a viewer in real time, 230). ≪ / RTI >

The regular area determining unit 320 determines whether the position of the viewer 230 obtained by the position obtaining unit 310 is within the predetermined area. At this time, the regular time zone is at least one area that can stereoscopically view a stereoscopic image displayed on the image display module 220. [

Hereinafter, the regular time zone will be described in more detail with reference to FIG.

4 is a view showing a regular region of the stereoscopic image display apparatus.

4, the regular time zones A1, A2, and A3 of the stereoscopic image display apparatus 200 according to an exemplary embodiment of the present invention are located at a position apart from the stereoscopic image display apparatus 200 by an optimum viewing distance r exist. These regular time zones A1, A2, and A3 are arranged at regular intervals in the horizontal direction. Therefore, if the position of the viewer is within the regular time zone such as P1, the viewer 230 can view the stereoscopic image.

On the other hand, the size and position of the regular time zone may be designed according to the type and characteristics of the image display module 220, or may be determined by factors such as image contents.

On the other hand, the area other than the regular area is also the area, and the viewer 230 also sees the inverted stereoscopic image in the area. P2 and P3, which are also shown, are the locations of the users included in the area.

3, when the viewer 230 views the video display module 220, the inverse stereoscopic image determining unit 330 determines whether the viewer 230 is in the first view provided on the left side of the viewer 230 or on the right side of the viewer 230 And determines whether the user is viewing the inverted stereoscopic image by the provided second view.

Hereinafter, the inverse stereoscopic image will be described in more detail with reference to FIG.

5 is a diagram showing a regular region and also an area of a stereoscopic image display apparatus displaying a plurality of views.

The stereoscopic image includes a plurality of views 510, and a plurality of views 510 are sequentially and repeatedly arranged. At this time, each view may include one or more images having the same time point. For example, the stereoscopic image may include four views 510 having different viewpoints as shown in FIG. 5, and 1,2,3,4,1, 2, 3, 4, .. ., 1, 2, 3, 4, and so on. At this time, the parallax between adjacent views may correspond to the binocular parallax. And, each view may include two images having the same viewpoint.

When the viewer 230 is located within the regular time zone A2, the viewer 230 views the stereoscopic image. More specifically, when the viewer 230 is positioned at P1, he sees 2 views in the left eye and 3 views in the right eye. At this time, 2 views correspond to the left eye image when comparing 3 views and the viewpoint, and 3 views correspond to the right eye image. Accordingly, the viewer 230 views the stereoscopic image by viewing the left eye image as the left eye and the right eye image as the right eye.

On the other hand, when the viewer 230 is located outside the regular time zone A2, the viewer 230 views the inverted stereoscopic image. More specifically, when the viewer 230 is located at P3, he sees four views as the left eye and one view as the right eye. At this time, the 4 view corresponds to the right eye image when one view is compared with the viewpoint, and one view corresponds to the left eye image. Accordingly, the viewer 230 views the left-eye image as the left eye image and the right-eye image as the right eye image, thereby viewing the inverted stereoscopic image.

Referring again to FIG. 3, in one embodiment, the inverse object determining unit 330 determines a view provided to the left eye of the viewer 230 (hereinafter, referred to as a 'first view') and a view , And 'second view') is outside the binocular disparity range, it can be determined that an inverse stereoscopic image is generated.

In another embodiment, the inverse input determining unit 330 can determine that the inverse stereoscopic image is generated when the viewer 230 is not within the time limit.

On the other hand, the inverse stereoscopic image determining unit 330 may provide information on the inverse stereoscopic image to the image correcting unit 340.

Next, the image correcting unit 340 corrects the inverted stereoscopic image determined by the inverse stereoscopic image determining unit 330. That is, the image correcting unit 340 corrects the inverse stereoscopic image by changing the first and second views provided as the left and right eye images of the viewer 230.

Hereinafter, correction for the inverse stereoscopic image will be described in more detail with reference to FIGS.

6 is a diagram for explaining a first embodiment of correction for inverse stereoscopic images.

Referring to FIG. 6, the image correcting unit 340 corrects the first view and the second view included in the inverse stereoscopic image 610. Here, the first view includes two first images (4) having a first viewpoint, and the second view includes two second images (1) having a second viewpoint different from the first viewpoint .

The image correcting unit 340 may correct at least one of the two first images 4 and the two second images 1 to a monochromatic image 620 having a specific gray level.

In one embodiment, the image correction unit 340 may correct at least one of the two first images 4 and the two second images 1 to a black image 620.

For example, the image correcting unit 340 may correct an image adjacent to the second image 1 of the two first images 4 to a black image 620. For example, the image correcting unit 340 may correct an image adjacent to the first image 4 of the two second images 1 to a black image 620.

This is because the monochromatic image 620 is inserted into the first and second views forming the inverted stereoscopic image 610 to further mitigate the adverse effect and smoothly implement the image. Also, when the viewer 230 recognizes the monochromatic image 620, it is possible to inform that the position of the current viewer 230 is also a region.

7 is a view for explaining a second embodiment of correction for an inverse stereoscopic image.

Referring to FIG. 7, the image correcting unit 340 corrects the first view and the second view included in the inverted stereoscopic image 610. Here, the first view includes two first images (4) having a first viewpoint, and the second view includes two second images (1) having a second viewpoint different from the first viewpoint .

The image correcting unit 340 corrects at least one of the two first images 4 and the two second images 1 into at least one image 620 having a viewpoint between the first viewpoint and the second viewpoint. can do.

For example, the image correction unit 340 may adjust the first image 4 adjacent to the second image 1 of the two first images 4 to have a third viewpoint between the first viewpoint and the second viewpoint, The third image 620 can be corrected. At this time, the third image 620 may correspond to an image corresponding to three views having a viewpoint between 4 view and 1 view.

Furthermore, the image correcting unit 340 corrects the second image 1 adjacent to the first image 4 of the two second images 1 to a second image 1 having the fourth image point between the third and second points of time, 4 < / RTI > At this time, the fourth image 620 may correspond to an image corresponding to two views having a viewpoint between 3 view and 1 view.

By inserting at least one image which is sequentially reduced in parallax between the first image 4 and the second image 1 having large parallax, the stereoscopic image display apparatus according to an embodiment of the present invention can display images It is possible to reduce the parallax when moving to the area and reduce the crosstalk. Accordingly, it is possible to reduce the sense of refusal when the viewer views the inverted stereoscopic image. Fig. 3 is a view for explaining a third embodiment of the present invention.

Referring to FIG. 8, the image correcting unit 340 corrects the first view and the second view included in the inverse stereoscopic image 610. Here, the first view includes two first images (4) having a first viewpoint, and the second view includes two second images (1) having a second viewpoint different from the first viewpoint .

The image correcting unit 340 may correct two or more of the two first images 4 and the two second images 1 to monochromatic images 620 having different gray levels. For example, the image correcting unit 340 corrects the first image 4 adjacent to the second image 1 of the two first images 4 to a black image, and converts the remaining first image 4 to a gray image And the second image 1 adjacent to the first image 4 of the two second images 1 can be corrected to a gray image. The image correcting unit 340 can smoothly express the inverted stereoscopic image 610 by gradually correcting the gray level of the monochromatic image as described above.

In one embodiment, the image correction unit 340 may detect the brightness of the first image and the second image included in the inverted stereoscopic image 610, and may determine the gray level of the monochromatic image using the detected brightness. This is to compensate the monochromatic image having a gray level corresponding to the luminance of the image being viewed, thereby reducing the visual difference with the adjacent view and minimizing the overall luminance reduction.

9A and 9B are diagrams showing examples of correction for the inverse stereoscopic image according to the first embodiment, where FIG. 9A shows the image before the correction, and FIG. 9B shows the image after the correction.

In the image shown in FIG. 9A, the parallax between the views is too large at the portion corresponding to the inverted stereoscopic image 910, so that the image is distorted and the viewer feels a sense of image heterogeneity.

On the other hand, in the image shown in FIG. 9B, a black image is inserted in a portion corresponding to the inverted stereoscopic image 910, the image is not broken, the stereoscopic image smoothly passes over, .

Figs. 10A and 10B are diagrams showing examples of correction for the inverse stereoscopic image according to the second embodiment, in which Fig. 10A shows the image before correction, and Fig. 10B shows the image after correction.

In the image shown in FIG. 10A, a parallax between images in a portion corresponding to the inverted-stereoscopic image 1010 is too large, so that the image is distorted.

On the other hand, the image shown in FIG. 10B can reduce the disparity of the image by inserting an image in which the parallax gradually decreases in the portion corresponding to the inverted stereoscopic image 1010.

Referring again to FIG. 3, the image output unit 350 outputs the stereoscopic image data corrected by the image correction unit 340.

Next, the timer 360 counts the time for the viewer 230 to watch the stereoscopic image outside the viewing area. The timer 360 may be activated or deactivated according to the determination result received from the time zone determination unit 320.

More specifically, the timer 360 can be operated when the time zone determination unit 320 determines that the viewer 230 is outside the viewing area. On the other hand, the timer 360 can stop the operation when it is determined that the viewer 230 is within the viewing area by the regular region determining unit 320. [

Next, the alarm notification unit 370 transmits an alarm notification message to the video output unit 350 so that the timer 360 can warn the viewer 230 through the video output unit 350 when a predetermined time has elapsed . Accordingly, the present invention can prevent the viewer 230 from watching stereoscopic images for a long time outside the viewing area.

In one embodiment, the warning notification unit 370 may transmit the warning notification message to the video output unit 350 in a stepwise manner. For example, the alarm notification unit 370 transmits a first warning notification message to the image output unit 350 when the timer 360 elapses the first time, and the timer 360 outputs a second time longer than the first time The second warning notification message can be transmitted to the video output unit 350. [

At this time, the first warning notification message and the second warning notification message cause the video output unit 350 to output different warning images. For example, the first warning notification message causes the image output module 350 to output a stereoscopic image in which a red band is inserted in a frame to the image display module 220. The second warning notification message causes the image output module 350 to output the stereoscopic image oscillated right and left to the image display module 220.

The stereoscopic image display apparatus according to an embodiment of the present invention is described as acquiring the viewer position by analyzing the viewer image captured by the camera module 210. However, in another embodiment, the viewer position is acquired by the sensor It might

Next, the position of the viewer 230 is obtained (S1102), and it is determined whether the position of the obtained viewer 230 corresponds to the time zone (S1103).

For example, in the stereoscopic image display mode, the stereoscopic image display apparatus 200 captures an image of a viewer 230 viewing a stereoscopic image displayed on the image display module 220, analyzes the captured image of the viewer, Location can be obtained.

Also, the stereoscopic image display apparatus 200 can detect the left and right eyes of the viewer in the viewer image, calculate the distance of the viewer 230 using the distance between the detected left and right eyes, The position of the viewer 230 can be specified using the distance of the viewer 230 and the coordinate information of the left and right eyes on the viewer image.

Next, the stereoscopic image display apparatus 200 performs correction for the inverse stereoscopic image (S1103 and S1104) if the viewer 230 is not in the regular time zone.

When the viewer 230 views an image outside the regular time zone, that is, also in the region, the right eye image corresponding to the first view is provided to the left eye of the viewer 230, and the left eye image corresponding to the second view is displayed to the viewer 230) to view the inverted stereoscopic image. Particularly, when the parallax between the first and second views of the viewer 230 exceeds the binocular disparity range, the viewer 230 can feel a great sense of heterogeneity of the image.

The stereoscopic image display apparatus 200 according to an exemplary embodiment of the present invention performs correction on the inverse stereoscopic image, thereby minimizing image heterogeneity.

The stereoscopic image display apparatus 200 performs correction for the first and second views. At this time, the first view includes at least one first image having a first viewpoint, and the second view includes at least one second image having a second viewpoint different from the first viewpoint.
