The stream signal input to the demultiplexer 310 may be a stream signal output from the tuner 110 or the demodulator 120 or the external device interface 130.

The image processing unit 320 may perform image processing of the demultiplexed image signal. For this, the image processing unit 320 may include a video decoder 325 and a scaler 335.

The video decoder 325 decodes the demultiplexed video signal and the scaler 335 performs scaling so that the resolution of the decoded video signal can be output from the display 180.

The video decoder 325 can include a decoder of various standards.

On the other hand, the image signal decoded by the image processing unit 320 can be divided into a case where there is only a 2D image signal, a case where a 2D image signal and a 3D image signal are mixed, and a case where there is only a 3D image signal.

For example, when an external video signal input from the external device 190 or a broadcast video signal of a broadcast signal received from the tuner unit 110 includes only a 2D video signal, when a 2D video signal and a 3D video signal are mixed And a case where there is only a 3D video signal. Accordingly, the controller 170, particularly, the image processing unit 320 and the like can process the 2D video signal, the mixed video signal of the 2D video signal and the 3D video signal, , A 3D video signal can be output.

Meanwhile, the image signal decoded by the image processing unit 320 may be a 3D image signal in various formats. For example, a 3D image signal composed of a color image and a depth image, or a 3D image signal composed of a plurality of view image signals. The plurality of viewpoint image signals may include, for example, a left eye image signal and a right eye image signal.

The processor 330 may control the overall operation in the image display apparatus 100 or in the control unit 170. [ For example, the processor 330 may control the tuner 110 to select a channel selected by the user or an RF broadcast corresponding to a previously stored channel.

In addition, the processor 330 may control the image display apparatus 100 by a user command or an internal program input through the user input interface unit 150. [

In addition, the processor 330 may perform data transfer control with the network interface unit 135 or the external device interface unit 130.

The processor 330 may control operations of the demultiplexing unit 310, the image processing unit 320, the OSD generating unit 340, and the like in the controller 170.

The OSD generation unit 340 generates an OSD signal according to a user input or by itself. For example, based on a user input signal, a signal for displaying various information in a graphic or text form on the screen of the display 180 can be generated. The generated OSD signal may include various data such as a user interface screen of the video display device 100, various menu screens, a widget, and an icon. In addition, the generated OSD signal may include a 2D object or a 3D object.

The OSD generating unit 340 can generate a pointer that can be displayed on the display based on the pointing signal input from the remote control device 200. [ In particular, such a pointer may be generated by a pointing signal processing unit, and the OSD generating unit 240 may include such a pointing signal processing unit (not shown). Of course, a pointing signal processing unit (not shown) may be provided separately from the OSD generating unit 240.

At this time, the OSD signal and the decoded video signal may include at least one of a 2D signal and a 3D signal. The mixed video signal is supplied to a frame rate converter 350.

A frame rate converter (FRC) 350 can convert the frame rate of an input image. On the other hand, the frame rate converter 350 can output the frame rate without conversion.

The formatter 360 may arrange the left eye image frame and the right eye image frame of the frame rate-converted 3D image. The left eye glass of the 3D viewing apparatus 195 and the synchronization signal Vsync for opening the right eye glass can be output.

The formatter 360 receives the mixed signal, i.e., the OSD signal and the decoded video signal, from the mixer 345, and separates the 2D video signal and the 3D video signal.

In the present specification, a 3D video signal means a 3D object. Examples of the 3D object include a picuture in picture (PIP) image (still image or moving picture), an EPG indicating broadcasting program information, Icons, texts, objects in images, people, backgrounds, web screens (newspapers, magazines, etc.).

On the other hand, the formatter 360 can change the format of the 3D video signal. For example, it can be changed to any one of various formats exemplified in FIG. Thus, according to the format, the operation of the eyeglass type viewing apparatus can be performed as shown in Fig.

That is, when the left eye image L is displayed on the display 180, the left eye glass of the shutter glass 195 is opened and the right eye glass is closed. When the right eye image R is displayed, The left eye glass is closed, and the right eye glass is opened.

On the other hand, FIG. 5B illustrates the operation of the 3D-use glass 195, particularly the polarizing glass 195, when the formatter 360 arranges and outputs the side-by-side format of the format shown in FIG. On the other hand, the 3D glass 195 applied in FIG. 5 (b) may be a shutter glass, and the shutter glass at this time may be operated as a polarizing glass by keeping both the left-eye glass and right-eye glass open .

Meanwhile, the formatter 360 may convert the 2D video signal into a 3D video signal. For example, according to a 3D image generation algorithm, an edge or a selectable object is detected in a 2D image signal, and an object or a selectable object according to the detected edge is separated into a 3D image signal and is generated . At this time, the generated 3D image signal can be separated into the left eye image signal L and the right eye image signal R, as described above.

Although not shown in the drawing, it is also possible that a 3D processor (not shown) for 3-dimensional effect signal processing is further disposed after the formatter 360. The 3D processor (not shown) can process the brightness, tint, and color of the image signal to improve the 3D effect. For example, it is possible to perform signal processing such as making the near field clear and the far field blurring. On the other hand, the functions of such a 3D processor can be merged into the formatter 360 or merged into the image processing unit 320. [ This will be described later with reference to FIG. 6 and the like.

Meanwhile, the audio processing unit (not shown) in the control unit 170 can perform the audio processing of the demultiplexed audio signal. To this end, the audio processing unit (not shown) may include various decoders.

In addition, the audio processing unit (not shown) in the control unit 170 can process a base, a treble, a volume control, and the like.

The data processing unit (not shown) in the control unit 170 can perform data processing of the demultiplexed data signal. For example, if the demultiplexed data signal is a coded data signal, it can be decoded. The encoded data signal may be EPG (Electronic Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel.

3, the signals from the OSD generating unit 340 and the image processing unit 320 are mixed in the mixer 345 and then 3D processed in the formatter 360. However, the present invention is not limited to this, May be located behind the formatter. That is, the output of the image processing unit 320 is 3D-processed by the formatter 360, and the OSD generating unit 340 performs 3D processing together with the OSD generation. Thereafter, the processed 3D signals are mixed by the mixer 345 It is also possible to do.

Meanwhile, the block diagram of the controller 170 shown in FIG. 3 is a block diagram for an embodiment of the present invention. Each component of the block diagram can be integrated, added, or omitted according to the specifications of the control unit 170 actually implemented.

In particular, the frame rate converter 350 and the formatter 360 are not provided in the controller 170, but may be separately provided.

6 is a diagram illustrating various scaling methods of a 3D image signal according to an exemplary embodiment of the present invention.

Referring to the drawing, in order to increase the 3-dimensional effect, the controller 170 may perform 3D effect signal processing. In particular, it is possible to perform a size adjustment or a tilt adjustment of a 3D object in a 3D image.

The 3D object 510 in the 3D image signal or the 3D image signal can be enlarged or reduced 512 as a whole at a certain ratio as shown in FIG. 6 (a), and also, as shown in FIG. 6 (b) , The 3D object may be partially enlarged or reduced (trapezoidal shape, 514, 516). 6 (d), at least a portion of the 3D object may be rotated (parallelogram shape 518). This scaling (scaling) or skew adjustment can emphasize the 3D effect of a 3D object in a 3D image or a 3D image, that is, a 3D effect.

On the other hand, as the slope becomes larger, the difference in length between the parallel sides of the trapezoidal shapes 514, 516 becomes larger as shown in Fig. 6B or 6C, .

The size adjustment or the tilt adjustment may be performed after the 3D image signal is aligned in a predetermined format in the formatter 360. [ Or in the scaler 335 in the image processing unit 320. [ On the other hand, the OSD generating unit 340 may generate an object in a shape as illustrated in FIG. 6 for the OSD generated for 3D effect enhancement.

Although not shown in the drawing, signal processing for a 3D effect (3-dimensional effect) may be performed by adjusting the brightness, tint, and brightness of an image signal or object, It is also possible that signal processing such as color adjustment is performed. For example, it is possible to perform signal processing such as making the near field clear and the far field blurring. The signal processing for the 3D effect may be performed in the controller 170 or may be performed through a separate 3D processor. Particularly, when it is performed in the control unit 170, it is possible to perform it in the formatter 360 or in the image processing unit 320 together with the above-described size adjustment or tilt adjustment.

FIG. 7 is a view for explaining how images are formed by a left eye image and a right eye image, and FIG. 8 is a view for explaining depths of a 3D image according to an interval between a left eye image and a right eye image.

First, referring to FIG. 7, a plurality of images or a plurality of objects 615, 625, 635, and 645 are illustrated.

First, the first object 615 includes a first left eye image 611 (L) based on the first left eye image signal and a first right eye image 613 (R) based on the first right eye image signal, It is exemplified that the interval between the first left eye image 611, L and the first right eye image 613, R is d1 on the display 180. [ At this time, the user recognizes that an image is formed at an intersection of an extension line connecting the left eye 601 and the first left eye image 611 and an extension line connecting the right eye 603 and the first right eye image 603. Accordingly, the user recognizes that the first object 615 is positioned behind the display 180. [

Next, since the second object 625 includes the second left eye image 621, L and the second right eye image 623, R and overlaps with each other and is displayed on the display 180, do. Accordingly, the user recognizes that the second object 625 is located on the display 180. [

Next, the third object 635 and the fourth object 645 are arranged in the order of the third left eye image 631, L, the second right eye image 633, R, the fourth left eye image 641, Right eye image 643 (R), and their intervals are d3 and d4, respectively.

According to the above-described method, the user recognizes that the third object 635 and the fourth object 645 are positioned at positions where the images are formed, respectively, and recognizes that they are located before the display 180 in the drawing.

At this time, it is recognized that the fourth object 645 is projected before the third object 635, that is, more protruded than the third object 635. This is because the interval between the fourth left eye image 641, L and the fourth right eye image 643, d4 is larger than the interval d3 between the third left eye image 631, L and the third right eye image 633, R. [

Meanwhile, in the embodiment of the present invention, the distance between the display 180 and the objects 615, 625, 635, and 645 recognized by the user is represented by a depth. Accordingly, it is assumed that the depth when the user is recognized as being positioned behind the display 180 has a negative value (-), and the depth when the user is recognized as being positioned before the display 180 (depth) has a positive value (+). That is, the greater the degree of protrusion in the user direction, the greater the depth.

8, the interval a between the left eye image 701 and the right eye image 702 in FIG. 8A is smaller than the interval between the left eye image 701 and the right eye image 702 shown in FIG. 8 (b) it is understood that the depth a 'of the 3D object in FIG. 8 (a) is smaller than the depth b' of the 3D object in FIG. 8 (b).

In this way, when the 3D image is exemplified as the left eye image and the right eye image, the positions recognized as images are different depending on the interval between the left eye image and the right eye image. Accordingly, by adjusting the display intervals of the left eye image and the right eye image, the depth of the 3D image or the 3D object composed of the left eye image and the right eye image can be adjusted.

FIG. 9 is a view illustrating a 3D image display of a polarization method and a 3D image display of a shutter method.

First, FIG. 9 (a) illustrates a 3D video display of a polarization method. The left eye image and the right eye image can be simultaneously displayed on the image display apparatus 100 and the left eye image and the right eye image are outputted to the outside by different polarization filters, for example, FPR, respectively.

The user wears the polarizing glass 195 to watch the left eye image with the left eye glass 195a and the right eye image with the right eye glass 195b.

In the drawing, the left eye image L1 and the right eye image R1 are displayed at T1, the left eye image L2 and the right eye image R2 are displayed at T2, the left eye image L3 and the right eye image R3 are displayed at T3, And the left eye image L4 and the right eye image R4 are displayed at T4.

Next, FIG. 9 (b) illustrates 3D-image display of the shutter system. In the image display apparatus 100, the left eye image and the right eye image are sequentially displayed.

The user wears the shutter glass 195 and sequentially watches the left eye image and the right eye image by sequentially opening and closing the left eye glass 195a and the right eye glass 195b.

In the drawing, it is exemplified that a left eye image L1 is displayed on T1, a right eye image R1 is displayed on T2, a left eye image L2 is displayed on T3, and a right eye image R2 is displayed on T4.

Fig. 10 is a diagram illustrating the reversal of the left eye image and the right eye image in the polarization method and the shutter method.

FIG. 10A illustrates that the left eye image and the right eye image are appropriately displayed during Ta, Tc, and Td during the polarization-based 3D image display, but the left eye image and the right eye image are reversed during Tb. In such a case, the user may feel dizzy or deteriorated in stereoscopic feeling when viewing the display image.

FIG. 10B illustrates that the left eye image and the right eye image are appropriately displayed during Ta and Tb during the shutter type 3D image display, but the left eye image and the right eye image are reversed during Tc and Td, respectively. In such a case, the user may feel dizzy or deteriorated in stereoscopic feeling when viewing the display image.

Especially when watching 3D images, since there is no guide presented, the user may ignore the slight inconvenience and continue to watch. If this state continues, it is easy to feel fatigue. In addition, whenever the user feels uncomfortable, checking the images while changing the left and right sides of the images interferes with smooth viewing, which is inefficient.

In the embodiment of the present invention, when the left eye image and the right eye image are reversed in a polarization method, a shutter method, or the like, an object indicating the judgment result is displayed. This will be described in detail with reference to FIG. 11 and the following figures.

FIG. 11 is a flowchart illustrating an operation method of an image display apparatus according to an embodiment of the present invention, and FIGS. 12 to 24B are referred to for explaining various examples of an operation method of the image display apparatus of FIG.

First, the control unit 170 of the video display device 100 receives an image. The received image may be a broadcast image through the broadcast receiving unit 105, an external input image through the external device interface unit 130 or the network interface unit 135, or a stored image through the storage unit 140.

Next, the image extracting unit 1210 of the image display apparatus 100 extracts the left eye image and the right eye image from the input image (S1110). For example, the image extracting unit 1210 may be provided in the formatter 360. 3, the formatter 360 may be provided in the control unit 170, but may be provided separately from the control unit 170. FIG. In the following, it is assumed that the formatter 360 is provided in the control unit 170. [

The image extracting unit 1210 can receive an image, particularly a 3D image. The 3D image may be divided into a left eye image and a right eye image, or a color difference image and a depth image.

The image extracting unit 1210 can extract the left eye image and the right eye image from the received multiple view image. Alternatively, the image extracting unit 1210 can extract the left eye image and the right eye image using the inputted color difference image and the depth image.

On the other hand, if the input image is a 2D image, the image extracting unit 1210 can convert the input image into a 3D image. The image extracting unit 1210 can extract the left eye image and the right eye image from the converted 3D image.

13 illustrates the left eye image 1310 and the right eye image 1315 extracted by the image extracting unit 1210. FIG.

The left eye image 1310 and the right eye image 1315 may have common background images and may have objects 1312 and 1317 whose positions are different from each other.

Next, the image display apparatus 100 arranges and displays the extracted left eye image and right eye image in a predetermined format (S1115).

For example, the image arrangement unit 1260 can arrange the extracted left eye image and right eye image in the interlace format of FIG. 4 (d) in the case of the polarization method. Then, the display 180 can simultaneously display the left eye image and the right eye image as shown in Fig. 9 (a).

As another example, the image arrangement unit 1260 can arrange the extracted left eye image and right eye image in the frame sequential format of FIG. 4 (c) in the case of the shutter system. Then, the display 180 can simultaneously display the left eye image and the right eye image, as shown in Fig. 9 (b).

Thus, an understanding user can feel a stereoscopic feeling while watching the left eye image and the right eye image.

Alternatively, step 1115 (S1115) may be performed between step 1130 (S1130) and step 1135 (S1135). That is, after determining whether the arrangement of the left eye image and the right eye image is correct, it is possible to display the left eye image and the right eye image.

Next, the image display apparatus 100 calculates parallax information using the extracted left eye image and right eye image (S1120).

The parallax information calculation unit 1220 receives the left eye image and the right eye image from the image extraction unit 1210, and calculates parallax information (disparity) between the left eye image and the right eye image.

For example, assuming that there is no vertical difference between the left eye image and the right eye image, the image extracting unit 1210 calculates the horizontal distance value of the corresponding pixel or block between the left eye image and the right eye image as parallax information can do. Here, the parallax information may be an object located closer to -, and a closer object closer to + may be located in front of the object.

As described above, the parallax information calculation between the left eye image and the right eye image can be referred to as stereo matching.

The parallax information calculation unit 1220 can generate a depth map of the left eye image and the right eye image based on the calculated parallax information.

The depth map is caused by parallax information per object, and can be generated with only luminance information without color information. That is, the higher the brightness level is, the more the object is projected, and the lower the brightness level is, the more the object is depressed.

FIG. 14 illustrates a depth map 1320 using parallax information between the left eye image 1310 and the right eye image 1315 of FIG.

On the other hand, the parallax information calculation unit 1220 can separate the objects having parallax information equal to or larger than the reference value into foreground images, and the objects less than the reference value can be separated into backgrounds based on the calculated parallax information.

For example, when the parallax information is divided into -127 to 128 levels, the closer to +, the more protruded, so that the level 10 can be set as the reference value. An object exceeding level 10 can be separated into foreground, and objects of level 10 or lower can be separated into a background. On the other hand, the reference value can be set at various levels, for example, it can be set to 0 level.

Fig. 15 illustrates that the foreground and the background are separated.

Fig. 15 (a) illustrates extraction of an area excluding the automobile object in the background 1510 from either the left eye image 1310 or the right eye image 1315 in Fig. 13, and Fig. 15 (b) An example of extracting an automobile object in the foreground 1520 from any one of the left eye image 1310 and the right eye image 1315 of FIG.

Next, the image display apparatus 100 calculates motion information for either the left eye image or the right eye image (S1125).

The motion information calculation unit 1230 receives the left eye image and the right eye image from the image extraction unit 1210, and calculates motion information on any one of the left eye image and the right eye image. Here, the motion information may include, for each image frame, a motion vector.

The motion information calculation unit 1220 can estimate the position of the unit block in the temporally preceding and succeeding frames. In particular, the motion information operation unit 1220 can search a block that minimizes a luminance difference between a specific block of the current frame and each pixel within a constant search area of the previous frame.

16 illustrates an example of extracting motion information from the motion information operation unit 1230. FIG.

Fig. 16 (a) shows the first image frame 1610 at time T1, and Fig. 16 (b) shows the second image frame 1620 at time T2.

The motion information calculation unit 1230 can calculate the motion vector MV based on the positional difference between the first image frame 1610 and the second image frame 1620 of the object 1615 representing the automobile.

Next, the image display apparatus 100 determines the arrangement of the left eye image and the right eye image based on the motion information and the time difference information (S1130).

The image arrangement determination unit 1240 receives the left eye image and the right eye image from the image arrangement unit 1260 and determines whether the arrangement of the left eye image and the right eye image is correct.

For this, the image arrangement determination unit 1240 can receive motion information from the motion information operation unit 1230 and time difference information from the time difference information operation unit 1220.

The criterion for determining whether the arrangement of the left eye image and the right eye image is correct, according to the embodiment of the present invention, is a boundary area around the foreground and a boundary area around the background.

Specifically, the image arrangement determining unit 1240 determines, based on the motion information, whether or not a part of the boundary area around the foreground is an occlusion area covered by the background area or a boundary area around the background In the case where a certain region is an area covering the foreground region, it is determined that the arrangement of the left eye image and the right eye image is reversed.

The direction of the motion vector MV is changed from the foreground 1715 to the background 1718 in a state in which the foreground 1715 and the background 1718 are separated from each other in the depth map 1710 as shown in Fig. 17 (a) The border area of the background 1718 is obscured. The occluded area can be called occlusion area.

If the arrangement of the left eye image and the right eye image is correct and the boundary region of the background 1718 is covered by the foreground 1715 but the arrangement of the left eye image and the right eye image is reversed, A phenomenon occurs in which the area is covered by the background 1718. [

In the embodiment of the present invention, in consideration of the foreground, background, and motion vector direction, it is determined whether the foreground is obscured, the background is obscured or not, and the arrangement of the left eye image and the right eye image is reversed Or not.

FIGS. 18 and 19 are drawings referred to for determining the arrangement of the left eye image and the right eye image.

FIG. 18 illustrates a case where the arrangement of the left eye image and the right eye image is correct.

Fig. 18A illustrates moving only the foreground among the background 1810 and the foreground 1815. Fig. 18B illustrates a case in which the background 1815 of Fig. 18A is displayed when the motion vector is the background direction in the foreground. The block B displayed on the screen 1820 is covered by the movement of the foreground 1815. [

18 (c) illustrates moving only the background among the background 1820 and the foreground 1825. Fig. 18 (d) shows the background 1815 of Fig. 18 (c) The block C displayed in the background 1820 is covered by the movement of the background 1820. [

19 illustrates a case where the arrangement of the left eye image and the right eye image is reversed. Thus, the foreground is shown behind and the background is shown in front.

Fig. 19A illustrates moving only the background 1910 out of the background 1910 and the foreground 1915. Fig. 19B illustrates a case where the motion vector is in the foreground direction in the background, The block E displayed in the block 1915 is covered by the movement of the background 1910. [

19C illustrates moving only the foreground among the background 1925 and the foreground 1920. Fig. 19D illustrates a case where the foreground 1920 of Fig. 19C is displayed when the motion vector is the background direction in the foreground. The block F displayed on the screen 1920 is covered by the movement of the foreground 1920. [

19, the block E or the block F displayed in the foreground 1915 is obscured by the movement of the background 1910 or the foreground 1920.

The image arrangement determining unit 1240 determines that the arrangement of the left eye image and the right eye image is reversed when the foreground image is obscured by using a feature that the foreground is obscured or the background is not maskable .

Next, the image display apparatus 100 displays the object indicating the determination result (S1125).

The image arrangement determination unit 1240 can digitize the arrangement of the left eye image and the right eye image reversed.

For example, the image arrangement determination unit 1240 may quantify the ratio of a boundary region in the depth map to an occluded region covered by another region or an area that covers another region.

That is, the ratio of the area of the occlusion area covered by the other area and the area of the area covering the other area, as compared with the area of the entire edge area in the depth map, can be calculated as the left eye right eye change probability.

The image arrangement determination unit 1240 can determine that the arrangement of the left eye image and the right eye image is reversed when the computed numerical value is equal to or larger than the reference value.

For example, if the left eye change probability is 30% or more, it can be determined that the arrangement of the left eye image and the right eye image is reversed.

Here, the reference value may be variable corresponding to at least one of the parallax information or the motion information. For example, as the parallax information becomes larger or the motion information becomes larger, or a combination thereof, the reference value may become larger. In other words, when the depth is large or when there is a large amount of motion, a case where the boundary is unintentionally hidden or hidden in the boundary area of the foreground or the boundary area of the background is issued. Therefore, the reference value can be raised in consideration of this.

On the other hand, the image arrangement determination unit 1240 can determine whether the left eye image and the right eye image have been changed for a plurality of frames, and then convert the left eye image and the right eye image into digital values. That is, it is also possible to calculate the left eye right eye change probability value for a predetermined period, average it, and determine whether the left eye and right eye images have been changed based on the averaged value.

The image arrangement determination unit 1240 can output an object representing the numerical value to the display 180 for display of the numerical value. Then, the display 180 can display these objects together when the 3D image is displayed.

Such an object may include at least one of a probability value, a color, a graphic image, and a pop-up window.

20 (a) illustrates the display of the 3D image 2010 and the left eye right eye change probability value 2015, which are suitable for the left eye image and the right eye image arrangement. The 3D image 2010 includes a foreground object 2014 and a background object 2012. [ In the figure, it is exemplified that the left eye right eye change probability value 2015 is 15%. With this probability value 2015, the user can easily see that the arrangement of the left eye image and the right eye image is suitable.

Next, FIG. 20B illustrates display of the 3D image 2020 in which the left eye image and the right eye image arrangement are reversed, and the left eye right eye change probability value 2025. The 3D image 2010 includes a foreground object 2024 and a background object 2022 in which the left eye image and the right eye image are reversed. In the figure, it is exemplified that the left eye right eye change probability value 2025 is 80%. With this probability value 2015, the user can easily see that the arrangement of the left eye image and the right eye image has been rearranged.

On the other hand, unlike the case of the digitization as shown in Fig. 20, various displays are possible.

FIG. 21 illustrates a display of a 3D image 2020 in which the left eye image and the right eye image are rearranged, and a bar type object 2125 showing a left eye right eye change. The greater the degree of reversal of the left eye image and the right eye image arrangement, the higher the height of the displayed bar.

22 illustrates display of the 3D image 2020 in which the left eye image and the right eye image arrangement are reversed, and the color object 2225 indicating the left eye right eye change. For example, in the case of a red object, it indicates that the left eye and the right eye have been changed, and in the case of yellow, it indicates that the arrangement of the left eye and right eye images is appropriate.

23 illustrates display of a 3D image 2020 in which the left eye image and the right eye image arrangement are reversed, and a pop-up window 2325 indicating a left eye right eye change. Such a pop-up window may disappear after being displayed for a certain time.

Next, the image display apparatus 100 determines whether or not there is a replacement input for the left eye and right eye images (S1140). If so, the arrangement positions of the left eye image and the right eye image are replaced and displayed (S1145).

The control unit 170 displays an object indicating that the left and right eye images have been rearranged and then determines whether or not there is a replacement input for changing the arrangement of the left eye and the right eye images from the user. Such replacement input can be performed using a specific key or a pointer of the remote control device, etc., under the 3D image setting menu.

The control unit 170 can replace the arrangement position of the left eye image and the right eye image of the displayed 3D image by the replacement input. Specifically, the image arrangement unit 1260 can replace the arrangement positions of the left eye image and the right eye image. Thus, the user can easily perform the replacement of the arrangement positions of the left eye image and the right eye image.

24A shows an example of replacement for the left eye and right eye images.

First, if there is a replacement input, an object 2410 representing the replacement input may be displayed on the display 180, as shown in FIG. 24A. At this time, when the replacement item 2412 is selected, the image arrangement unit 1260 replaces the arrangement positions of the left eye image and the right eye image of the displayed 3D image. That is, as shown in FIG. 24B, the arrangement of the 3D image 2010 of a suitable arrangement can be displayed on the display 180.

On the other hand, when it is determined that the left eye image and the right eye image are reversed in the image arrangement determination unit 1240, the image arrangement determination unit 1240 may control the arrangement of the left eye image and the right eye image to be automatically changed have. Thereby, the image arranging unit 1260 replaces the arrangement positions of the left eye image and the right eye image of the displayed 3D image. That is, the 3D image 2010 of the arrangement can be rearranged and displayed on the display 180, as shown in FIG. 24B, without displaying the object indicating the replacement as shown in FIG. 24A.

As a result, according to the embodiment of the present invention, it is possible to determine whether the left and right sides of the stereo image have been changed using only the information of the input image, and to present the guide to the user. Therefore, the user can avoid seeing the image in the state where the left and right are changed for a long time, so that the user can feel comfortable for a long time.

It is to be understood that the present invention is not limited to the configuration and the method of the embodiments described above but may be applied to all or any of the embodiments so that various modifications may be made. Some of which may be selectively combined.

Meanwhile, the operation method of the image display apparatus of the present invention can be implemented as a code that can be read by a processor on a recording medium readable by a processor included in the image display apparatus. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium that can be read by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave such as transmission over the Internet . In addition, the processor-readable recording medium may be distributed over network-connected computer systems so that code readable by the processor in a distributed fashion can be stored and executed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
