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.

4, the format of the 3D video signal is a side-by-side format (Fig. 4A) in which the left eye image signal L and the right eye image signal R are arranged left and right, A frame sequential format (FIG. 4C) for arranging in a time division manner, an interlaced format (FIG. 4B) for mixing the left eye image signal and the right eye image signal line by line 4d), a checker box format (FIG. 4e) for mixing the left eye image signal and the right eye image signal box by box, and the like.

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 mixer 345 may mix the OSD signal generated by the OSD generator 340 and the decoded video signal processed by the image processor 320. 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 converts the frame rate of an input image. For example, a frame rate of 60 Hz is converted to 120 Hz, 240 Hz, or 480 Hz. When converting the frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame between the first frame and the second frame, or insert the third frame predicted from the first frame and the second frame. When converting a frame rate of 60 Hz to 240 Hz, it is possible to insert three more identical frames or insert three predicted frames. In the case of converting the frame rate of 60 Hz to 480 Hz, it is possible to insert seven more frames of the same frame or to insert seven frames of the predicted frame.

On the other hand, the frame rate converter 350 can output the frame rate as it is without any additional frame rate conversion. Preferably, when a 2D video signal is input, the frame rate can be output as it is. On the other hand, when a 3D video signal is input, the frame rate can be varied as described above.

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. Accordingly, according to the format, the operation of the 3D viewing device of the glasses type can be performed as shown in FIG.

5A illustrates operation of the 3D-use glass 195, particularly, the shutter glass 195 when the formatter 360 arranges and outputs the frames in the frame sequential format of the format shown in FIG. 4. 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.

For example, if the demultiplexed speech signal is a coded speech signal, it can be decoded. Specifically, when the demultiplexed speech signal is an MPEG-2 standard encoded speech signal, it can be decoded by an MPEG-2 decoder. In addition, if the demultiplexed speech signal is a coded voice signal of the MPEG 4 BSAC (Bit Sliced Arithmetic Coding) standard according to a terrestrial DMB (Digital Multimedia Broadcasting) scheme, it can be decoded by an MPEG 4 decoder. Also, if the demultiplexed speech signal is an encoded audio signal of the AAC (Advanced Audio Codec) standard of MPEG 2 according to the satellite DMB scheme or DVB-H, it can be decoded by the AAC decoder. If the demultiplexed speech signal is a Dolby AC-3 standard encoded audio signal, it can be decoded by an AC-3 decoder.

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. For example, the EPG information may be ATSC-PSIP (ATSC-Program and System Information Protocol) information in the case of the ATSC scheme and may include DVB-SI information in the DVB scheme . The ATSC-PSIP information or the DVB-SI information may be information included in the above-mentioned stream, that is, the header (2 bytes) of the MPEG-2 TS.

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 235 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 negative 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) (b ') of the 3D object shown in Fig. 8 (b) is larger than the depth a' of the 3D object shown in Fig. 8 (a).

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.

9 to 11 are views referred to explain the image display apparatus according to the embodiment of the present invention.

Currently, some video display devices include 3D auto-detect function of contents. However, if 3D function such as 3D World or HDMI in is available, auto-detect only in 3D mode, detect function is turned on. The reason I do not always turn on 3D auto detection is because of the high detection error rate.

For example, if there is a scene in which a window is arranged symmetrically in a 2D image, it can be recognized as a 3D image and forced to change to a 3D mode. If the 2D image is forcibly changed to the 3D image, the user can not see the proper image.

In recent years, a video display device has been connected to a network to freely use the Internet, and a smart function for installing and using various applications has been supported. In addition, there may be applications that support 3D among various applications.

For example, by creating Side-By-Side and Top-Bottom screens in applications such as wallpaper, home launchers, and games, You can see it as a solid. For such applications, it is possible to turn on the 3D auto detection function and to provide the convenience to the user if the side-by-side, top-bottom, etc. screens can be automatically converted to the 3D mode.

An image display apparatus 100 according to an embodiment of the present invention includes a display 180 for displaying a 3D setting screen for a plurality of applications, an interface 180 for receiving a user's 3D setting input regarding at least one of the plurality of applications, A setting unit 140 for setting the 3D setting input, a setting unit 150 for setting and storing the setting corresponding to the 3D setting input for each application or setting and storing the setting corresponding to the activity of the predetermined application, And a control unit 170 for controlling the display unit.

If you turn on the 3D auto detection function for all applications, you can force 3D conversion even if it is not 3D as described above.

In this case, the user feels very uncomfortable, and the 3D auto detection function is turned off and the image display device is used.

Also, in this case, the user has the inconvenience of turning on the 3D mode every time the same 3D supporting application is executed.

However, the present invention can set and store various 3D environment settings such as a 3D auto sensing function for each application, or set and store each 3D environment setting for each predetermined application.

The 3D setting input may be an input for setting at least one of whether to automatically convert to a 3D mode (whether or not a 3D automatic sensing function is used), a 3D format such as a side-by-side, a top-bottom, .

In addition, the 3D setting input may be an input for setting to switch to the 3D mode automatically when the set application is executed or in response to the predetermined activity of the set application. In this case, the 3D setting input may further include an input for setting a format of the 3D image.

Accordingly, it is possible to provide the user with the convenience of automatically converting a stereoscopic 3D image from a specific screen of a predetermined application or executing a predetermined application.

9 to 11 show various examples of the 3D setting screen.

The control unit 170 may control the display unit 180 to display the 3D setting screen when the user executes the setting menu or when the user switches to the 3D mode while the application is running.

According to an embodiment of the present invention, a user can manage an application to be turned on in 3D automatic detection function.

Referring to the 3D setting screen 900 shown in FIG. 9, an application supporting 3D or an application desired to be used in 3D among a plurality of applications 910 installed in the video display device or available via the web can be automatically detected The function item 930 can be set to be turned on.

On the other hand, an application 920 that is not set to the 3D auto detection function item does not turn on the 3D auto detection function by default.

On the other hand, if the user manually converts the 3D mode during execution of the application 920 which is not set as the 3D automatic detection function item, the user can inquire whether or not to set the item as the 3D automatic detection function item.

On the other hand, in the case of the application set as the 3D automatic detection function item, it is possible to set not to switch to the 3D mode unconditionally at the time of executing the application, but to turn on the 3D automatic detection function from the specific scene and switch to the 3D mode.

For example, in the case of using an Android OS, each scene may be configured as an activity, and the activity may correspond to a specific scene of the predetermined application.

On the other hand, the conversion of each activity is known at the framework level.

For example, when a user selects a GameMain activity 1043 from among a plurality of activities 1041, 1042, 1043, and 1044 on the detail setting screen 1000 for a predetermined application 1010 as shown in FIG. 10, The controller 170 can automatically control to switch to the 3D mode when entering the GameMain activity. On the other hand, the selected activity 1043 may display an object 1050 indicating the setting.

Alternatively, you can set the user to turn on the 3D auto-sensing and execution feature in an activity called GameStart (not shown), which will automatically turn on 3d mode when entering an activity called GameStart.

On the other hand, the detailed setting screen 1000 for the predetermined application 1010 in FIG. 10 may be a setting screen for the application 920 in which the automatic 3D item is not turned on.

For example, the user can select the manual setting item 1020 and the manual setting item 1020 of the automatic setting item 1030 to set the mode to be switched to the 3D mode on the specific screen without switching to the 3D mode immediately when the application is executed have.

In addition, one embodiment of the present invention recognizes a pattern of a user and can set a point at which 3D should be automatically turned on. For example, in Android, if you manually turn on 3D in an activity called GameStart, you can save this point and use it from hereafter.

In contrast to the embodiment shown in FIG. 10, even when the application is set to the 3D automatic sensing function item, the 3D automatic sensing function is turned on from a specific scene instead of being switched to the 3D mode unconditionally at the time of execution of the application, Mode can be set.

11, the application 1110 detailed setting screen 1100 set as the 3D automatic detection function item includes a manual setting item 1120, an automatic setting item 1130, a plurality of activities 1141, 1142, 1143, and 1144, May be displayed.

If the user selects the predetermined activity 1053, the control unit 170 can control the 3D mode automatically when entering the selected activity. The selected activity 1043 includes an object 1150 ) Can be displayed.

Meanwhile, in one embodiment of the present invention, 3D formats such as side-by-side and top-bottom can also be set. For example, the user can set the 3d mode in a top-bottom manner in an activity called GameStart, and the control unit 170 can automatically turn on the top-bottom 3D mode when entering an activity called GameStart.

In the conventional 3D TV, since the specifications of the 3D image format are not unified with respect to the 3D contents and the 3D image format information is not included, the viewer must directly view the 3D TV after selecting the 3D image format.

In addition, every time the content is used, there is an inconvenience to newly select a 3D image format.

Thus, an embodiment of the present invention may store 3D image format settings for a given application and then apply automatically stored 3D format settings when using the same broadcast application.

Meanwhile, the control unit 170 may control the setting to be stored for each logged-in user account.

The video display device often has a plurality of users such as a family member, and the applications installed for each user may be different or have different preference settings. The video display device is generally used by a plurality of users at the same time in the home. However, in some cases, the video display device may be used alone.

Therefore, by storing and managing account-specific settings for each logged-in user, it is possible to prevent other users from changing the preferences of individual users or to prevent inconvenience of other users using the video display device.

Meanwhile, the controller 170 may control the stored settings to be transmitted to a server connected through a network. The control unit 170 can transmit the 3D setting details of the user to an external server or an electronic device through the network interface unit 135. [

On the other hand, 3D mode-related settings (auto detection and execution, 3D type, 3D on, etc.) can be defined in advance by dividing the version of each application and the package name and managed by the server, have. Also, the pattern of usage can be updated to the server.

According to the present invention, in the case of using 3D contents, in particular, applications supporting 3D, the 3D-related setting can be performed simply and conveniently, thereby improving usability of the user.

The image display apparatus and the operation method thereof according to the present invention are not limited to the configuration and method of the embodiments described above but the embodiments can be applied to all or some of the embodiments 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.
