4 is a diagram illustrating an example of a 3D video signal format capable of implementing 3D video. The 3D video signal format may be determined according to a method of disposing a left eye image and a right eye image generated to implement a 3D image.

The 3D image may be composed of a multi-view image. The user may view the multi-view image through the left eye and the right eye. The user may feel a three-dimensional effect of the 3D image through the difference of the image detected through the left eye and the right eye. According to an embodiment of the present invention, a multi-view image for implementing a 3D image includes a left eye image that can be recognized by the user through the left eye and a right eye image that can be recognized through the right eye.

As shown in FIG. 4A, a method in which the left eye image and the right eye image are arranged left and right is referred to as a side by side format. As shown in FIG. 4B, a method of disposing the left eye image and the right eye image up and down is referred to as a top / down format. As shown in FIG. 4C, a method of time-divisionally arranging a left eye image and a right eye image is called a frame sequential format. As shown in FIG. 4D, a method of mixing the left eye image and the right eye image for each line is called an interlaced format. As shown in FIG. 4E, a method of mixing the left eye image and the right eye image for each box is called a checker box format.

The image signal included in the signal input to the image display apparatus 100 from the outside may be a 3D image signal capable of realizing a 3D image. In addition, the graphic user interface image signal generated to display the image display apparatus 100 related information or to input a command related to the image display apparatus 100 may be a 3D image signal. The formatter 260 may mix the 3D image signal and the graphic user interface 3D image signal included in the signal input to the image display apparatus 100 from the outside and output the mixed image to the display 180.

5 is a diagram illustrating various scaling methods of a 3D video signal according to an embodiment of the present invention. For adjusting the size or tilt of the 3D object, see FIG. 5. 5 illustrates various ways of scaling of 3D video signals.

As shown in (a) of FIG. 5, the 3D image signal or the 3D object 510 in the 3D image signal may be enlarged or reduced 513 as a whole, and as shown in FIG. 5B, the 3D object may be enlarged. It may be partially enlarged or reduced (trapezoidal, 516). In addition, as shown in FIG. 5C, at least a part of the 3D object may be rotated (parallel quadrilateral shape 519). Through such scaling (scaling) or tilting, it is possible to emphasize a three-dimensional effect, that is, a three-dimensional effect, on a 3D image signal or a 3D object in the 3D image signal.

As described above, increasing the slope may increase the length difference between the parallel sides of the trapezoidal shape 416, as shown in FIG. 5 (b), or as shown in FIG. It can mean getting bigger.

In this case, scaling of the 3D video signal may be performed by the formatter 260 of the controller 170 described above. The 3D video signal of FIG. 5 may be a left eye video signal, a right eye video signal, or a signal in which a left eye video signal and a right eye video signal are combined.

The formatter 260 may receive the decoded video signal, separate the 2D video signal or the 3D video signal, and separate the 3D video signal into a left eye video signal and a right eye video signal. The left eye video signal and the right eye video signal may be scaled to one or more of the various examples shown in FIG. 5 and output in a predetermined format as shown in FIG. 4. Scaling can, on the other hand, be performed before or after the output format is formed.

In addition, the formatter 260 may receive an OSD signal of the OSD generator 174 or an OSD signal mixed with the decoded video signal, separate the 3D video signal, and separate the 3D video signal into a multi-view video signal. . For example, the 3D video signal may be divided into a left eye video signal and a right eye video signal, and the separated left eye video signal and the right eye video signal may be scaled as shown in FIG. 5 and output in a predetermined format shown in FIG. 4. .

The OSD generator 240 may directly perform the above-described scaling process with respect to the OSD output. When the OSD generator 240 directly performs scaling on the OSD, the formatter 260 does not need to perform scaling on the OSD. In this case, the OSD generator 240 not only generates the OSD signal, but also scales the OSD signal according to the depth or slope of the OSD, and further outputs the OSD signal in a suitable format. In this case, the format of the OSD signal output from the OSD generator 240 may be any one of various combination formats of a left eye image signal and a right eye image signal, or a left eye image and a right eye image, as shown in FIG. 4. In this case, the output format is the same as the output format of the formatter 260.

The user recognizes that the extension occurs at the point where the extension line connecting the left eye 601 and the first left eye image 611 and the extension line connecting the right eye 603 and the first right eye image 603 cross each other. Accordingly, the user recognizes that the first object 615 is located behind the display 180. The distance between the display 180 and the first object 615 recognized by the user may be expressed as a depth. In the present embodiment, the depth of the 3D object recognized by the user, as located behind the display 180, has a negative value (−). Therefore, the depth of the first object 615 has a negative value.

The user recognizes that the extension line connecting the left eye 601 and the second left eye image 621 and the extension line connecting the user's right eye 603 and the second right eye image 623 cross each other. Thus, the user recognizes the second object 625 as if it was displayed on the display 180. In this case, the second object 625 may be referred to as a 2D object and may be referred to as a 3D object. The second object 625 is an object having the same depth as the display 180, and the depth of the second object 625 is zero.

The third object 635 and the fourth object 645 are examples for explaining 3D objects that are recognized as being protruded toward the user on the display 180. Furthermore, the degree of perspective or stereoscopic perception perceived by the user according to the change of the distance between the left eye image and the right eye image may be described with reference to the examples of the third object 635 and the fourth object 645.

The third object 635 includes a third right eye image 633 (denoted as R3) and a third left eye image 663 and denoted by L3. The interval between the third right eye image 633 and the third left eye image 631 is set to d3. The user recognizes that an extension line connecting the left eye 601 and the third left eye image 631 and the point where the extension lines of the right eye 603 and the third right eye image 633 cross each other. Accordingly, the user recognizes that the third object 625 is located in front of the display 180, that is, near the user. That is, the third object 635 is recognized by the user as if it is positioned to protrude toward the user on the display 180. In the present embodiment, the depth of the 3D object recognized by the user, as located in front of the display 180, has a positive value (+). Thus, the depth of the third object 635 has a positive value.

The fourth object 645 is composed of a fourth right eye image (indicated by R3) and a fourth left eye image (indicated by 641 and L4). The interval between the fourth right eye image 643 and the fourth left eye image 641 is set to d4. Here, an inequality of 'd3 <d4' is established between d3 and d4. The user recognizes that an extension line connecting the left eye 601 and the fourth left eye image 641 and the extension line of the right eye 603 and the fourth right eye image 643 intersect. Accordingly, the user recognizes that the fourth object 645 is located in front of the display 180, that is, closer to the user, and closer to the user than the third object 635. That is, the fourth object 645 is recognized by the user as if the fourth object 645 is positioned to protrude toward the user rather than the display 180 and the third object 635. The fourth object 645 has a depth positive value.

The image display apparatus 100 adjusts the positions of the left eye image and the right eye image displayed on the display 180 so that an object consisting of the left eye image and the right eye image is recognized or positioned in front of the user as if the object is composed of the left and right eye images. It can be made visible to the user as if it were a user. In addition, the image display apparatus 100 may adjust the display interval of the left eye image and the right eye image displayed on the display 180 to adjust the depth of the object composed of the left eye image and the right eye image.

That is, according to the description with reference to FIG. 6, the depth of the object composed of the left eye image and the right eye image has a positive value (+) or a negative value (-) according to the left and right display positions of the left eye image and the right eye image. It can be seen that it is determined. As described above, an object having a positive value (+) having a depth is an object that is recognized by the user as if it is positioned to protrude from the display 180. In addition, an object having a negative value (−) having a depth is an object that is recognized by the user as if it is located backward from the display 180.

6, the depth of the object, that is, the distance between the point recognized by the user as if the 3D image is located and the display 180 vary according to the absolute value of the distance between the left eye image and the right eye image. Can be.

7 is a diagram illustrating a state in which a sense of depth of an image is controlled according to an embodiment of the present invention. Referring to FIG. 7, it can be seen that the depth of the same image or the same 3D object varies depending on the distance between the left eye image 701 and the right eye image 702 displayed on the display 180. In this embodiment, the depth of the display 180 is set to zero. The depth of the image to be recognized as if protruding from the display 180 is set to have a positive value.

The interval between the left eye image 701 and the right eye image 702 illustrated in FIG. 7A is a. The interval between the left eye image 701 and the right eye image 702 illustrated in FIG. 7B is b. Where b is greater than a. That is, in the example illustrated in FIG. 7B, the interval between the left eye image 701 and the right eye image 702 is wider than the example illustrated in FIG. 7A.

In this case, as described with reference to FIG. 6, the depth of the 3D image or the 3D object illustrated in FIG. 7B is greater than the depth of the 3D image or the 3D object illustrated in FIG. 7A. . In each case, when the depth is quantified and expressed as a 'and b', respectively, it can be seen that a '<b' relationship is also established according to a <b. In other words, when the 3D image is projected, the depth of the expression may be increased or decreased as the distance between the left eye image 701 and the right eye image 702 is increased or decreased.

In addition, the power supply unit is a module for supplying power required for driving the spatial remote control. According to an example, when the power supply unit outputs a signal for commanding that the remote control unit temporarily stops or resumes the power supply according to the movement of the spatial remote controller detected by the sensing unit, the power supply unit supplies power according to the control signal. By varying t, power can be saved while the spatial remote control is not used or not in operation.

As another example, a predetermined command may be input to the image display apparatus 100 in response to the movement of the spatial remote control 201. That is, even if a predetermined pressure or a touch is not detected in the user input unit, a predetermined command may be input or generated only by the movement of the spatial remote controller. For example, when moving back and forth of the spatial remote control 201, the size of the image displayed on the image display apparatus 100 may be enlarged or reduced. Therefore, examples regarding the spatial remote controller do not limit the scope of the present invention.

FIG. 14 shows a news content list displayed in a state in which the image display device is pivoted in a vertical type 182, where the contents of the news can simultaneously view still images and text information, and a plurality of news window objects 1410, 1420, and 1430. ) Is open, the contents of the other news can be checked only by changing the arrangement order of the objects 1410, 1420, 1430 with a spatial remote control or a user gesture.

The plurality of objects 1410, 1420, and 1430 may be displayed to have different depths.

15A to 15B illustrate a state in which the image display device is pivoted to the vertical type 182 when a plurality of images are received for one content, such as a case where a plurality of camera images for each actual location of a stadium are received during a baseball game. An example of simultaneously displaying a plurality of images 1510, 1520, and 1530 is illustrated.

In particular, since contents such as sports game relaying are photographed by a plurality of cameras, a user can enjoy a game from various viewpoints. In the example of FIG. 15A, a close-up image of a pitcher and a batter may be simultaneously displayed and enjoyed in addition to the main relay image.

In some embodiments, at least one of the plurality of images may be a 3d image. Referring to FIG. 15B, the main relay image 1540 may be displayed as a 3d image, and the remaining images of the pitchers and batters 1510 and 1520 may be displayed as general 2d images.

That is, according to an exemplary embodiment, at least one area or an object of the display unit may be displayed as a 3D stereoscopic image.

Meanwhile, when the main image or the user selected image 1610 is to be enjoyed on a wide screen, as shown in FIG. 16, the image display device may display the content while being pivoted by the horizontal type 181.

Referring to FIGS. 17A through 18, a plurality of contents or objects 1710, 1720, 1810, and 1820 may be arranged in a vertical direction and displayed. In addition, the plurality of contents or objects may be displayed in a matrix form in which the number of rows is larger than the number of columns.

Meanwhile, the plurality of contents or objects 1710, 1720, 1810, and 1820 may be displayed as 3D images that appear to protrude toward the user. In addition, the depth and the size of the 3D image may be displayed by varying the depth of the 3D image.

In detail, signal processing may be performed based on data transmitted from the image processor 220, and the formatter 260 may generate a graphic object for a 3D image. In this case, the depth of the 3D object may be set differently from that of the display 180 or another image displayed on the display 180.

The controller 170, in particular, the formatter 260 may signal at least one of the display size and the depth of the 3D object to vary. As the depth increases, the distance between the left eye 3D object and the right eye 3D object is increased. Signal processing can be made smaller.

Meanwhile, when a user setting signal through a spatial remote controller, a user's operation detected by the sensor unit, or a user setting signal by a touch is input, contents and objects may be edited according to a corresponding command. The order of the divided screens and the order of the objects can be changed according to the user's preference, so that the order of the photo slide show of the EMF (Electronic Media Frame), the order of the music list, etc. can be edited.

When setting the slide show order and the music list order of the photo images, the vertical type 182 may be used, and when the slide show or music playback 1810 is started, the horizontal type 181 may be viewed according to the picture.

FIG. 17B is an example of inverting the order of two contents or objects 1730 and 1740 in FIG. 17A, and FIG. 17C shows the contents or objects 1730, 1740 and 1750 arranged in one column in FIG. 17A in a downward direction. This is an example of rotating and editing.

The controller 170 may determine the hand motion of the user after displaying the 3D object 1810. The controller 170 may determine the user's hand motion through the motion sensor. The motion sensor may include a camera that detects a hand of a part of a user's body and photographs a hand motion.

The controller 170 may determine whether the user's hand gesture corresponds to the set hand gesture. If the user's hand gesture corresponds to the set hand gesture, the controller 170 may control the image display apparatus 100 according to a command corresponding to the set hand gesture. For example, the user's hand gesture may correspond to a command for selecting a button displayed on a predetermined area of the 3D object. In this case, the controller 170 may stop the playback of the image display apparatus 100 or adjust the volume according to a command corresponding to the selected button, for example, stop playback, volume control, or the like.

Meanwhile, the characteristic of the content or the object may include whether it is a 3d image. In addition, in the case of a 3D image, as described above with reference to FIG. 1, the display 180 may be implemented as an additional display method for viewing a 3D image, and may include a passive method such as a polarized glasses type, It may be divided into an active method such as a shutter glass type.

Thus, for viewing 3D images, an additional display 195 for 3D may be provided, either passive or active.

FIG. 19 illustrates an example in which the 3D additional display 195 is tilted when the user tilts or lie down, and the image display device is pivoted accordingly.

On the other hand, when a user lies down or tilts his head while watching a 3D image, in a passive method such as a polarized glasses type, the polarization angles of the image display device and the polarized glasses are shifted so that the image may not be seen and the shutter glass is shuttered. In the case of an active method such as a glass type, a crosstalk phenomenon may increase.

Therefore, when the property of the content or object is a 3d image, that is, when the 3d image is displayed, the image display apparatus may be pivoted based on the inclination angle of the 3D additional display 195.

Meanwhile, in consideration of a problem that may occur in the case of the 3d image, the priority of the 3d image among the attributes of the content may be set higher than other attributes. For example, in the case of a 3D image, the content or object includes a plurality of still images, a plurality of moving images, and a still image having a length longer than a width. And at least one of a video having a length longer than the width, the robot may not be pivoted vertically.

Similarly, it is also possible for the user to set the properties of various contents differently so as to pivot the image display apparatus accordingly.

According to the present invention, the screen area of the image display apparatus can be efficiently used according to the situation by changing the pivot mode of the image display apparatus that can be pivoted horizontally or vertically according to the characteristics of the content or object desired by the user. In addition, editing of the displayed content or object is easy.

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 may 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 devices that store data that can be read by the processor. Examples of the processor-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, 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. . The processor-readable recording medium can also be distributed over network coupled computer systems so that the processor-readable code is stored and executed in a distributed fashion.

In addition, while the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims.
