On the other hand, in the plurality of image display mode according to an embodiment of the present invention, it is possible to implement a plurality of OSD generation unit 340. For example, for displaying the OSD in the first image, the first OSD generator may generate the first OSD, and for displaying the OSD in the second image, the second OSD generator may generate the second OSD.

As described above, the object processing in the first image and the object in the second image are performed in parallel through different paths, thereby improving signal processing speed.

The mixer 345 may mix the OSD signal generated by the OSD generator 340 and the decoded image signal processed by the image processor 320. In this case, the OSD signal and the decoded video signal may each include at least one of a 2D signal and a 3D signal. The mixed video signal is provided to the 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 data as it is without additional frame rate conversion.

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

Meanwhile, in the present specification, the 3D video signal is meant to include a 3D object. Examples of the object include a picture in picture (PIP) image (still image or a video), an EPG indicating broadcast program information, various menus, widgets, There may be an icon, text, an object in the image, a person, a background, a web screen (newspaper, magazine, etc.).

The formatter 360 may change the format of the 3D video signal. For example, it may be changed to any one of various formats illustrated in FIG. 4. Accordingly, according to the format, as shown in FIG. 5, the operation of the viewing apparatus of the glasses type may be performed.

First, FIG. 5A illustrates an operation of the 3D glasses 195, in particular the shutter glass 195, when the formatter 360 arranges and outputs the frame sequential format among the formats of 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.

FIG. 5B illustrates an operation of the 3D glass 195, in particular, the polarization glass 195 when the formatter 360 arranges and outputs the side-by-side format among the formats of FIG. 4. Meanwhile, the 3D glass 195 applied in FIG. 5B may be a shutter glass, and the shutter glass may be operated as a polarized glass by keeping both the left eye glass and the right eye glass open. .

Meanwhile, the formatter 360 may convert the 2D video signal into a 3D video signal. For example, an edge or selectable object may be detected within the 2D image signal according to a 3D image generation algorithm, and an object or selectable object according to the detected edge may be separated into a 3D image signal and generated. Can be. 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 figure, a 3D processor (not shown) for processing a 3D effect signal may be further disposed after the formatter 360. The 3D processor (not shown) may process brightness, tint, and color adjustment of an image signal to improve 3D effects. For example, signal processing may be performed to sharpen the near distance and blur the far distance. Meanwhile, the functions of the 3D processor may be merged into the formatter 360 or merged into the image processor 320. This will be described later with reference to FIG. 6 and the like.

For example, when the demultiplexed data signal is an encoded data signal, it may 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 in each channel.

In FIG. 3, the signals from the OSD generator 340 and the image processor 320 are mixed in the mixer 345 and then 3D processed in the formatter 360, but the present invention is not limited thereto. May be located after the formatter. That is, the output of the image processor 320 is 3D processed by the formatter 360, and the OSD generator 340 performs 3D processing together with OSD generation, and then mixes each processed 3D signal by the mixer 345. It is also possible.

Meanwhile, a block diagram of the controller 170 shown in FIG. 3 is a block diagram for one embodiment of the present invention. Each component of the block diagram may be integrated, added, or omitted according to the specification of the controller 170 that is actually implemented.

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

6 is a diagram illustrating various scaling methods of 3D video signals according to an embodiment of the present invention.

Referring to the drawings, in order to increase the 3D effect, the controller 170 may perform 3D effect signal processing. Among them, in particular, the size or tilt of the 3D object in the 3D image may be adjusted.

As shown in FIG. 6A, the 3D image signal or the 3D object 510 in the 3D image signal may be enlarged or reduced 512 as a whole at a predetermined ratio, and as shown in FIGS. 6B and 6C. The 3D object may be partially enlarged or reduced (trapezoidal shapes 514 and 516). In addition, as illustrated in FIG. 6D, at least a part of the 3D object may be rotated (parallel quadrilateral shape) 518. Through such scaling (scaling) or tilting, it is possible to emphasize a three-dimensional effect, that is, a three-dimensional effect, of a 3D image or a 3D object in the 3D image.

On the other hand, as the slope becomes larger, as shown in FIG. 6 (b) or 6 (c), the length difference between the parallel sides of the trapezoidal shapes 514 and 516 increases, or as shown in FIG. 6 (d), the rotation angle is increased. It gets bigger.

Meanwhile, the size adjustment or the tilt adjustment may be performed after the 3D video signal is aligned in a predetermined format in the formatter 360. Alternatively, it may be performed by the scaler 235 in the image processor 320. On the other hand, the OSD generation unit 340, it is also possible to create the object in the shape as shown in Figure 6 to generate the OSD to emphasize the 3D effect.

For example, signal processing may be performed to sharpen the near distance and blur the far distance. Meanwhile, the signal processing for the 3D effect may be performed in the controller 170 or may be performed through a separate 3D processor. In particular, when performed in the controller 170, it may be performed in the formatter 360 together with the above-described size adjustment or tilt adjustment, or may be performed in the image processor 320.

FIG. 7 is a diagram illustrating an image formed by a left eye image and a right eye image, and FIG. 8 is a diagram illustrating a depth 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 first left eye images 611 and L based on the first left eye image signal and first right eye images 613 and R based on the first right eye image signal. An interval between the first left eye image 611 and L and the first right eye image 613 and R is illustrated to be 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 located behind the display 180.

Next, since the second object 625 includes the second left eye images 621 and L and the second right eye images 623 and R and overlaps each other, the second object 625 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 the third left eye image 631 and L, the second right eye image 633 and R, and the fourth left eye image 641 and L and the fourth object, respectively. The right eye images 643 and R are included, and the 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 the positions where the images are formed, respectively, and in the drawing, each of them is located in front of the display 180.

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 exemplary embodiment of the present invention, the distance between the display 180 and the objects 615, 625, 635, and 645 recognized by the user is expressed as a depth. Accordingly, the depth when the user is recognized as if it is located behind the display 180 has a negative value (-), and the depth when the user is recognized as if it is located before the display 180. (depth) is assumed to have a negative value (+). That is, the greater the degree of protrusion in the direction of the user, the greater the size of the depth.

Referring to FIG. 8, the distance a between the left eye image 701 and the right eye image 702 of FIG. 8A is the distance between the left eye image 701 and the right eye image 702 shown in FIG. 8B. If (b) is smaller, it can be seen that the depth a 'of the 3D object of FIG. 8 (a) is smaller than the depth b' of the 3D object of FIG. 8 (b).

As such, when the 3D image is exemplified as the left eye image and the right eye image, a position recognized as image formation from the user's point of view varies depending on the distance between the left eye image and the right eye image. Therefore, by adjusting the display interval of the left eye image and the right eye image, it is possible to adjust the depth of the 3D image or 3D object composed of the left eye image and the right eye image.

FIG. 9C illustrates a case in which the user moves the remote control apparatus 200 away from the display 180 while pressing a specific button in the remote control apparatus 200. As a result, the selection area in the display 180 corresponding to the pointer 205 may be zoomed in and enlarged. On the contrary, when the user moves the remote controller 200 to be closer to the display 180, the selection area in the display 180 corresponding to the pointer 205 may be zoomed out and reduced. 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, while pressing a specific button in the remote control device 200 can recognize the up, down, left and right movement. That is, when the remote control device 200 moves away from or near the display 180, the up, down, left and right movements are not recognized, and only the front and back movements can be recognized. In a state where a specific button in the remote controller 200 is not pressed, only the pointer 205 moves according to the up, down, left, and right movements of the remote controller 200.

Meanwhile, the moving speed or the moving direction of the pointer 205 may correspond to the moving speed or the moving direction of the remote control apparatus 200.

When selected, the plurality of image display mode entry signals are transmitted to the controller 170, thereby entering the dual mode.

 That is, the video display device 100 displays the plurality of video images such that the first viewer can watch the first video and the second viewer can watch the second video while the same size of the main video and the sub video. Enter the mode.

Next, an object representing wearing of the viewing apparatus is displayed (S1115).

The controller 170, in particular, the OSD generator 340 generates an object 1220 indicating wearing of the viewing apparatus, and displays the same as shown in FIG. 14B.

FIG. 14B illustrates that an object 1220 indicating wearing of the viewing apparatus is displayed on the display 180. For example, when it is determined in FIG. 14A to enter the plurality of image display modes, the corresponding object 1220 may be displayed. On the other hand, when the hot key is operated or when a plurality of image display mode objects in a predetermined menu are selected, the corresponding object 1220 may be displayed without displaying in FIG. 14A.

Next, the first image and the second image are displayed on the display according to the multi-image display mode, and an identifier is added to at least one of the first image or the second image and displayed. After the predetermined time, the identifier is removed and the first image and the second image are displayed on the display (S1125).

The controller 170 controls the display 180 to display the first image and the second image according to the plurality of image display modes.

The first image or the second image may be any one of a received broadcast image, an external input image input from the outside, an image stored in the image display apparatus 100, a broadcast program guide image, or a home screen image.

For example, when the first image and the second image are broadcast images, it is preferable that they are broadcast images of different channels. Accordingly, each user can watch different images.

Meanwhile, in order to receive broadcast images of different channels, the tuner 110 in the broadcast receiver 105 may include a plurality of tuners. Alternatively, the first broadcast channel may be received through the tuner unit 110, and the second broadcast channel may be received through the network interface unit 135.

As another example, the first image may be a broadcast image, and the second image may be an external input image. Accordingly, each user can watch different images from different sources or different routes.

The controller 170 may arrange the input first image and the second image in a predetermined format, and control to simultaneously display the arranged first image and the second image.

The formatter 360 in the control unit 170 displays the input first and second images, as illustrated in FIG. 4, in a side by side format (FIG. 4A), a top down format (FIG. 4B), and an interlace format ( 4D), a checker box format (FIG. 4E), or the like.

Accordingly, the display 180 can display the first image and the second image by spatially dividing the same. As a result, the plurality of users may wear different passive viewing apparatuses 195 to distinguish and watch the first image and the second image.

Meanwhile, FIG. 16 illustrates image signal processing for viewing a plurality of images using polarized glass.

The formatter 360 in the controller 170 receives the first image 1310 and the second image 1320, and mixes the first image and the second image in an interlace format (FIG. 4D) among the formats of FIG. 4. An image 1330 is generated.

The display 180 simultaneously displays the corresponding image 1330. In this case, a film including a left-eye polarization pattern and a right-eye polarization pattern, for example, a film-type patterned retarder (FPR), corresponding to the interface format, may be disposed on the display 180.

Accordingly, the first user wearing the first viewing device 195a made of the left eye polarizing glass may view only the first image 1340 of the display image 1330. In addition, the second user wearing the second viewing apparatus 195b made of the right eye polarizing glass may view only the second image 1350 of the display image 1330. Accordingly, different images can be viewed for each user.

On the other hand, the control unit 170, in particular, the formatter 360 in the control unit 170 arranges the input first image and the second image in a frame sequential format, and sequentially displays the arranged first image and the second image. Can be controlled.

Accordingly, the display 180 may sequentially display the first image and the second image. As a result, the plurality of users may wear different active viewing apparatuses 195 and may separately view the first image and the second image.

17 illustrates image signal processing for viewing a plurality of images by using a shutter glass.

The formatter 360 in the controller 170 receives the first image 1310 and the second image 1320, and temporally displays the first image and the second image in a frame sequential format (FIG. 4C) among the formats of FIG. 4. To generate an image 1335 mixed with each other. That is, the vertical sync frequency is doubled.

The display 180 sequentially displays the corresponding image 1335. Accordingly, the first user who wears the shutter glass 195a in which both the left eye glass and the right eye glass are opened for the first time t = t1, only the first image 1340 that is displayed first among the display images 1335. You will watch. In addition, the second user who wears the shutter glass 195b in which both the left eye glass and the right eye glass are opened for the second time t = t2 may watch only the second image 1350 of the display image 1335. Accordingly, different images can be viewed for each user.

Meanwhile, in order for the first user wearing the first viewing device to watch the first image, the first image should be distinguished from the second image. In addition, in order for the second user wearing the second viewing device to watch the second image, the second image should be distinguished from the first image.

In an embodiment of the present invention, to distinguish between the first image and the second image, an identifier is added to at least one of the first image and the second image.

For example, to add an identifier, the controller 170 may change the edge, luminance, or color of at least one of the first image and the second image to be distinguished from each other.

As another example, to add an identifier, the controller 170 may control to display a text or an object in at least one of the first image and the second image.

As another example, to add an identifier, the controller 170 may control to differently output a sound corresponding to at least one of the first image and the second image.

As another example, to add an identifier, the controller 170 may display at least one of the first image and the second image to flutter or vibrate.

18 illustrates that the first image 1510 of the predetermined broadcast channel DTV 7-1 and the second image 1520 of the predetermined broadcast channel DTV9-1 are simultaneously displayed on the display 180. For convenience of description, the first image 1510 and the second image 1520 are arranged in a top-and-bottom format.

For example, when all of the first viewing device 195a includes the left eye (L) polarized glass, and the second viewing device 195b includes the right eye (R) polarized glass, the first viewing device ( The first user wearing 195a perceives only the first image 1510, and the second user wearing the second viewing device 195b recognizes only the second image 1520.

In this case, unlike the second image 1520, the edge of the first image 1510 may be thickened or color may be added to the edge.

In FIG. 18A, the edge of the first image 1510 is displayed in bold. As a result, the first user wearing the passive first viewing apparatus 195a can easily distinguish the desired first image. Unlike the drawing, the edge of the second image 1520 may also be varied. However, it is preferable to vary the frame so as to be distinguished from the edge of the first image 1510.

On the other hand, after a predetermined time elapses, that is, a time elapsed so that the first user and the second user can distinguish the first image and the second image, respectively, the above-described edge variation may be removed.

That is, as shown in FIG. 18B, the first image 1510 and the second image 1520 may be displayed as they are without displaying the edge of the first image 1510 in bold. As a result, it is possible to stably watch a desired video without disturbing viewing due to the identifier.

Meanwhile, unlike FIG. 18, the edge of the first image 1510 may be displayed in red, and the edge of the second image 1520 may be displayed in blue.

That is, as illustrated in FIG. 20A, a text 2010 of 'L' may be displayed in the first image 1510 and a text 2020 of 'R' may be displayed in the second image 1520. As a result, the first user wearing the passive first viewing device 195a can easily distinguish a desired first image, and the second user wearing the second viewing device 195b can have a desired second image. Images can be easily distinguished.

On the other hand, after a predetermined time elapses, that is, a time elapsed so that the first user and the second user can distinguish the first image from the second image, the above-described text display may be removed.

That is, as shown in FIG. 20B, the first image 1510 and the second image 1520 may be displayed as it is without text display. As a result, it is possible to stably watch a desired video without disturbing viewing due to the identifier.

Meanwhile, unlike FIG. 20, the first text in the first image 1510 may be displayed in red, and the second text in the second image 1520 may be displayed in blue.

For example, to distinguish between the first viewing device 195a and the second viewing device 195b, at least a portion of the first viewing device 195a is displayed in red, and at least a portion of the second viewing device 195a. Is displayed in blue, each user can easily distinguish the first image 1510 and the second image 1520, and at the same time, the first viewing device 195a and the second viewing device 195b. It can be easily distinguished.

Meanwhile, unlike the drawing, in order to distinguish the first viewing device 195a and the second viewing device 195b, the shapes of the first viewing device 195a and the second viewing device 195b may be changed. For example, the glass shape of the first viewing device 195a may be circular, and the glass shape of the second viewing device 195b may be rectangular.

As another example, the text 'L' may be displayed on the first viewing device 195a, and the text 'R' may be displayed on the second viewing device 195b. As a result, the user can easily distinguish the viewing apparatus.

Meanwhile, although FIG. 20 illustrates distinguishing the first image from the second image through text, it is also possible to distinguish the first image from the second image through an object. For example, different objects may be added to the first image and the second image as identifiers, respectively. As a result, the user can easily distinguish the first image from the second image.

FIG. 21 illustrates that the first image 2105 of the predetermined broadcast channel DTV 7-1 and the second image 2115 of the predetermined broadcast channel DTV9-1 are sequentially displayed on the display 180. do. That is, the first image 2105 is displayed at the first time t1 and the second image 2115 is displayed at the second time t2 according to the frame sequential format.

Accordingly, the first viewing device 195a is synchronized with the first time t1, both the left eye glass and the right eye glass are opened, and the second viewing device 195b is synchronized with the second time t2 with the left eye glass. Both the and right eye glasses are open.

At this time, similar to FIG. 20, the text 2110 of 'L' may be displayed in the first image 2105, and the text 2120 of 'R' may be displayed in the second image 2115. As a result, a first user wearing the active first viewing device 195a can easily distinguish a desired first image, and a second user wearing the second viewing device 195b wants a second user. Images can be easily distinguished.

On the other hand, after a predetermined time elapses, as shown in FIG. 21B, the first image 2105 is displayed at the third time t3 without text display, and the second image 2115 is displayed at the fourth time t4 as shown in FIG. 21B.
