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. To this end, the image processing unit 320 may include a video decoder 225 and a scaler 235. [

The video decoder 225 decodes the demultiplexed video signal and the scaler 235 performs scaling so that the resolution of the decoded video signal can be output from the display 180.

The video decoder 225 may 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.

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.

For example, when a 3D image is input in the above-described various formats, it can be changed to a multi-view image. In particular, it is possible to change the multiple viewpoint image to be repeated. Thereby, the 3D image of the non-spectacle type can be displayed.

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 may be a multiple view image signal as described above.

However, 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.

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. [

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 negative value (+). That is, the greater the degree of protrusion in the user direction, the greater the depth.

6, the interval a between the left eye image 701 and the right eye image 702 in FIG. 6A is smaller than the interval between the left eye image 701 and the right eye image 702 shown in FIG. 6 (b) it is found that the depth a 'of the 3D object in Fig. 6 (a) is smaller than the depth b' of the 3D object in Fig. 6 (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. 7 is a diagram showing a control method of the remote control apparatus of FIG. 3. FIG.

As shown in FIG. 7A, it is exemplified that the pointer 180 corresponding to the remote control device 200 is displayed on the display 180. FIG.

The user can move or rotate the remote control device 200 up and down, left and right (Fig. 7 (b)), and back and forth (Fig. 7 (c)). The pointer 205 displayed on the display 180 of the video display device corresponds to the movement of the remote control device 200. [ In this remote control device 200, as shown in the figure, since the pointer 205 is moved according to the movement in the 3D space, it can be called a space remote controller.

7B illustrates that when the user moves the remote control apparatus 200 to the left, the pointer 205 displayed on the display 180 of the image display apparatus moves to the left correspondingly.

Information on the motion of the remote control device 200 sensed through the sensor of the remote control device 200 is transmitted to the image display device. The image display apparatus can calculate the coordinates of the pointer 205 from the information on the motion of the remote control apparatus 200. [ The image display apparatus can display the pointer 205 so as to correspond to the calculated coordinates.

7C illustrates a case in which the user moves the remote control device 200 away from the display 180 while pressing a specific button in the remote control device 200. FIG. Thereby, the selected area in the display 180 corresponding to the pointer 205 can be zoomed in and displayed. Conversely, when the user moves the remote control device 200 close to the display 180, the selection area within the display 180 corresponding to the pointer 205 may be zoomed out and zoomed out. On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 approaches the display 180, the selection area may be zoomed in.

On the other hand, when the specific button in the remote control device 200 is pressed, it is possible to exclude recognizing the up, down, left, and right movement. That is, when the remote control apparatus 200 moves away from or approaches the display 180, it is not recognized that the up, down, left, and right movements are recognized, and only the forward and backward movements are recognized. Only the pointer 205 is moved in accordance with the upward, downward, leftward, and rightward movement of the remote control device 200 in a state where the specific button in the remote control device 200 is not pressed.

On the other hand, the moving speed and moving direction of the pointer 205 may correspond to the moving speed and moving direction of the remote control device 200.

FIG. 9 is a flowchart showing an operation method of an image display apparatus according to an embodiment of the present invention, and FIGS. 10 to 20 are referred to for explaining various examples of an operation method of the image display apparatus of FIG.

Referring to FIG. 9, a 2D image area and a 3D image area are distinguished from each other and displayed on the display (S910).

The control unit 170 of the image display apparatus may set the input 3D image as a 3D image region and the generated OSD menu as a 2D image region when the input image is a 3D image and there is an OSD display input . It is also possible to control the input 3D image to be displayed in the 3D image area of the display 180 and to control the generated OSD menu to be displayed in the 2D image area of the display 180. [

10 illustrates an example in which the display 180 is divided into a 2D image area 1020 and a 3D image area 1010. FIG.

Although not shown in the drawing, the autostereoscopic 3D image as well as the 2D image can be viewed by using the lens unit 195 disposed apart from the display 180.

At this time, the lens unit 195 is divided into a first region (region 1) and a second region (region 2) corresponding to the 3D image region 1010 and the 2D image region 1020 of the display 180, Other power sources can be applied. Accordingly, the user can simultaneously view the autostereoscopic 3D image and the normal 2D image.

The first region (region 1) and the second region (region 2) of the lens section 195 can be controlled independently of each other by using the characteristics of active liquid crystals. Will be described later.

On the other hand, when the lens unit 195 is a lenticular system using a refractive index, a lenticular array may be formed in a horizontal direction as shown in Fig. 11 (a), or a lenticular array may be formed in a vertical direction . Alternatively, unlike the drawing, the lenticular array may be formed in a matrix form.

Next, the first power source is applied to the first area of the lens unit corresponding to the 3D image area (S920), and the second power source is applied to the second area of the lens unit corresponding to the 2D image area (S930).

The control unit 170 controls the first power source to be applied to the first area of the lens unit 195 corresponding to the 3D image area of the display and controls the second area of the lens unit corresponding to the 2D image area, .

12 illustrates the structure of the lens unit 195 according to the embodiment of the present invention and the refractive index difference according to the applied power source.

The lens unit 195 includes a first plate 1210 and a second plate 1215 that are spaced apart from each other and a power source is applied to the first plate 1210 and the second plate 1215, 1230 and a first layer 1220 and a second layer 1225 disposed between the first and second plates 1210 and 1215 and surrounding the liquid crystal 1230.

The first plate 1210 and the second plate 1215 are preferably formed of a transparent member for light transmission and are formed of a metal member for power supply. For example, the first plate 1210 and the second plate 1215 may be formed of ITO electrodes.

The first layer 1220 and the second layer 1225 may surround the liquid crystal 1230. For this purpose, the first layer 1220 and the second layer 1225 may be formed of polyimide (PI) or the like.

On the other hand, the liquid crystal 1230 is extraordinary refracted or ordinary refracted according to the power applied to the first plate 1210 and the second plate 1215. That is, the liquid crystal exhibits anisotropic properties depending on the applied power source.

12 (a), when the first power source V1, for example, a 0 V power source is applied between the first plate 1210 and the second plate 1215, the dispersed liquid crystal 1230, The orientation direction is not constant and the refractive index of the polymer layers 1220 and 1225 and the refractive index of the liquid crystal 1230 are different from each other. Therefore, scattering occurs between the PI layers 1220 and 1225 and the liquid crystal 1230, and an autostereoscopic 3D effect can be obtained by this effect.

12 (b), when the second power source V2 is applied between the first plate 1210 and the second plate 1215, the liquid crystal 1230 is aligned in the direction parallel to the electric field And the normal refractive indexes of the polymer layers 1220 and 1225 and the liquid crystal 1230 are coincident with each other, and a 2D effect can be obtained.

13 is a diagram for explaining a sweet zone and a dead zone according to the user's position when the lens unit 195 of the lenticular system by the non-eyeglass system is used.

The display 180 may display the plurality of viewpoint images V1 to V10, and the lens unit 195 may refract the corresponding images and output the images in the user direction.

 In the autostereoscopic 3D system, the apparatus has an advantage in that it can feel a three-dimensional feeling to multi-users who do not wear special stereoscopic glasses. However, in a unit zone, for example, a solid zone can be felt only in a sweet zone 1310, and a position where a user is not suitable for moving or viewing a 3D stereoscopic effect, for example, a dead zone where a reversal of a left image and a right image takes place zone, 1320), not only can not feel the stereoscopic effect properly, but also provide dizziness and discomfort.

In addition, in the non-eyeglass 3D system, the user must stay within a limited position to view the OSD menu. Even if the user is located in the sweet zone 1310, a text image, such as a user OSD menu, It becomes unnatural. In addition, each user located in the dead zone 1320 provides an unnatural OSD menu with no stereoscopic effect.

On the other hand, when the text or the caption flows, the user who is located in the dead zone 1320 as well as the user located in the sweet zone 1310 is not only visually dizzy but also inconvenient.

In order to solve this problem, in the embodiment of the present invention, the display 180 is divided into a 3D image area and a 2D image area, and the lens part 195 also includes a first area corresponding to the 3D image area and a 2D image area, And displays the 2D image and the 3D image together.

In particular, it is possible to provide images that are vulnerable to non-eyeglass 3D viewing such as OSD menus, preview images, etc. as 2D images. Thus, it is possible to view the OSD menu, the preview image, and the like at any position.

FIG. 14 illustrates that a 2D image 1415 is displayed in the entire area 1410 of the display 180. FIG. At this time, the second power source V2 is applied to the entire area of the lens unit 195 as shown in FIG. 12 (b), so that the liquid crystal can be arranged in the user direction. Thereby, the user can view the 2D image 1415. [

FIG. 15 illustrates that a 3D image 1510 is displayed on the entire display 180. FIG. At this time, the first power source V1, for example, 0 V power source is applied to the entire area of the lens unit 195 as shown in FIG. 12A, and the liquid crystal may be arranged in a direction different from the user direction. Thereby, the user can view the 3D image 1515 while feeling the 3D effect.

FIG. 16 illustrates that a part of the display 180 is displayed as a 2D image area and the other area is displayed as a 3D image area.

For example, as shown in FIG. 15, if the 3D image is displayed in the entire area of the display 180, and the OSD menu display input is received while viewing the 3D image, the 3D image 1615 And display the OSD menus 1625 and 1630 on the 2D video area 1620. [

As described above, the lens unit 195 applies the first power source V1 to the first region corresponding to the 3D image region 1610 and applies the first power source V1 to the 2D image region 1620 The second power source V2 is applied to the corresponding second region as shown in Fig. 12 (b). Accordingly, the user can stably view a desired OSD menu as a 2D image.

 On the other hand, the OSD menu may include an image quality setting menu related to the brightness or contrast of the 3D image, or a 3D setting menu related to the depth of the 3D image.

In the drawing, the "3D option line setting" menu 1625 and the "detailed options" menu 1730 are illustrated, but various settings are possible. On the other hand, when the "3D detail setting" item 1627 is selected from the "3D option setting" menu 1625, the depth of the 3D image can be adjusted in the "detailed option" menu 1730.

On the other hand, when a predetermined item is selected through the 3D setting menu related to the image quality setting menu or the depth of the 3D image in the OSD menu, the 3D image displayed in the 3D image area is variably displayed corresponding to the selected item It is also possible.

For example, in the image quality setting menu, when the brightness increase item is selected, the brightness of the 3D image in the 3D image area 1610 can be varied and displayed. That is, the 3D image area 1610 may operate as a preview area by menu operation.

In another example, in the 3D setting menu, when the depth increasing item is selected, the depth of the 3D image in the 3D image area 1610 can be varied and displayed.

On the other hand, after the menu adjustment through the OSD menu has been completed, or after the OSD menu has been displayed, without any additional input, and after a predetermined time has elapsed, the 3D image may be displayed in the entire area of the display 180 again as shown in FIG.

Meanwhile, if there is an input for varying at least one of the 2D image region or the 3D image region (S940), the variable 2D image region or the variable 3D image region is divided and displayed on the display (S950).

When there is an input for varying at least one of a 2D image area and a 3D image area in a state in which a 2D image and a 3D image are classified into a 2D image area and a 3D image area, According to the input, the variable 2D image region or the variable 3D image region is classified and displayed on the display.

Next, in accordance with the variable input, the first power source is applied to the third region of the lens portion corresponding to the variable 3D image region, or the second power source is applied to the fourth region of the lens portion corresponding to the variable 2D image region (S960).

The controller 170 controls to apply the first power source to the third area of the lens unit 195 corresponding to the variable 3D image area of the display and controls the fourth area of the lens unit corresponding to the variable 2D image area So that the second power source is applied.

FIG. 17 illustrates that the 2D image region 1720 is reduced as compared to FIG. For example, when the area adjustment object 1640 is moved downward, an enlarged 3D image area 1710 and a reduced 2D image area 1720 can be set as shown in FIG. 17, as compared with FIG.

At this time, the first power source V1 is applied to the third region corresponding to the enlarged 3D image region 1710, and the reduced 2D image region 1715 The second power source V2 may be applied to the fourth region corresponding to the second power source V2 as shown in Fig. 12 (b).

On the other hand, the area adjustment object 1640 can be operated using the direction key of the remote control device 200 or the direction key in the local key.

Alternatively, the area adjustment object 1640 may be operated using a space remote controller in which a pointer is displayed according to the movement according to the embodiment of the present invention. Thus, the area adjustment can be performed easily.

FIG. 18 illustrates displaying a 3D image as a preview when viewing a 2D image.

The 2D image region 1810 and the 3D image region 1820 are displayed on the display 180 as shown in FIG. 18 when a 2D preview image is displayed on the display 180 as shown in FIG. 14, A 2D image 1815 that has been viewed can be displayed in the 2D image area 1810 and a 3D image 1825 related to the 2D image being viewed can be displayed as a preview image in the 3D image area 1820. [

To this end, the control unit 170 may control to convert the 2D image being reproduced into a 3D image, and to display the converted 3D image in the 3D image area 1820 of the display 180. Accordingly, the user can easily check the preview of the 3D image.

19 illustrates that a part of the display 180 is displayed as a 2D image area and the other area is displayed as a 3D image area.

In particular, a 3D image 1915 may be displayed in the 3D image area 1910 and an input format menu 1925 may be displayed in the 2D image area 1920 to determine the 3D image format to be input.

In the drawing, the top down format item, the side by side item, and the frame sequential item are displayed in the input format menu 1925, but various modifications are possible.

At this time, when the side by side item is selected, a preview area 1930 showing a preview of the input format may be displayed together with the displayed 3D image.

Thereby, the user can easily select the 3D image format to be input.

Fig. 20 exemplifies display of a caption or the like as a 2D video area and another area as a 3D video area when there is a caption or text.

The control unit 170 controls the subtitle to be displayed in the 2D image area and displays the input 3D image in the 3D image area when there is a caption whose display position is changed according to time in the input 3D image.

20A, when the position of the caption 2025 is at the first position, the caption is displayed in the 2D image area 2020, and the other 3D image 2015 is displayed in 3D And is displayed in the video area 2010. FIG.

20B shows a case where the caption 2035 is positioned at the second position and the caption is displayed in the 2D image region 2020 and the other 3D image 2015 is displayed at the 3D image region 2010). ≪ / RTI >

In this way, when the flowing subtitle is included in the 3D image, it is separated and displayed separately so that the user can comfortably watch the subtitle.
