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 175 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 175 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 plurality of view video signals. . 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 174 may scale a 3D image or 3D object generated based on the output OSD signal. When the OSD generator 174 directly performs scaling on the OSD, the formatter 175 does not need to perform scaling on the OSD. In this case, the OSD generator 174 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 174 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. At this time, the output format is the same as the output format of the formatter 175.

According to an embodiment of the present invention described above, the 3D image is composed of a multiview image, wherein the multiview image may be illustrated as a left eye image and a right eye image. In this case, FIG. 6 illustrates a state in which a position recognized as an image is formed from a user's point of view is changed by a distance between a left eye image and a right eye image. Referring to FIG. 6, a stereoscopic or perspective view of an image felt by a user according to an interval or parallax between a left eye image and a right eye image will be described.

In FIG. 6, a plurality of images or objects having different depths are illustrated. These objects are referred to as a first object 615, a second object 625, a third object 635, and a fourth object 645.

That is, the first object 615 is composed of a first left eye image based on the first left eye image signal and a first right eye image based on the first right eye image signal. That is, the video signal for displaying the first object includes a first left eye video signal and a first right eye video signal. 6 illustrates at which position of the display unit 180 the first left eye image based on the first left eye image signal and the first right eye image based on the first right eye image signal are displayed. 6 illustrates a distance between the first left eye image and the first right eye image displayed on the display unit 180. The description of the first object may be applied to the second to fourth objects. Hereinafter, for convenience of description, a left eye image and a right eye image displayed on the display unit 180 for one object, an interval set between the two images, and a serial number of the corresponding object will be described.

The first object 615 includes a first right eye image 613 (indicated by R1 in FIG. 6) and a first left eye image 611 (indicated by L1 in FIG. 6). The interval between the first right eye image 613 and the first left eye image 611 is set to d1. 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 unit 180. The distance between the display unit 180 and the first object 615 recognized by the user may be expressed as a depth. In the present exemplary embodiment, the depth of the 3D object recognized by the user, as located behind the display unit 180, has a negative value (−). Therefore, the depth of the first object 615 has a negative value.

The second object 625 is composed of a second right eye image (indicated by 623 and R2) and a second left eye image (indicated by 621 and L2). According to the present exemplary embodiment, the second right eye image 623 and the second left eye image 621 are displayed at the same position on the display unit 180. The interval between the second right eye image 623 and the second left eye image 621 is zero. 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. Accordingly, the user recognizes the second object 625 as if it is displayed on the display unit 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 unit 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 from the display unit 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 the third object 625 as if it is located in front of the display unit 180, that is, near the user. That is, the third object 635 is recognized by the user as if the display unit 180 protrudes toward the user. In the present exemplary embodiment, the depth of the 3D object recognized by the user, as located in front of the display unit 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 unit 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 located protruding toward the user rather than the display unit 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 unit 180 so that an object consisting of the left eye image and the right eye image is recognized or displayed to the user as if the object is located behind the display unit 180. It can be made known to the user as if it were located. 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 unit 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, the object having a positive value (+) having a depth is an object recognized by the user as if the object is protruded from the display unit 180. In addition, an object having a negative value (−) having a depth is an object recognized by the user as if it is located backward from the display unit 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 unit 180 vary according to the absolute value of the distance between the left eye image and the right eye image. can do.

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 unit 180. In the present embodiment, the depth of the display unit 180 is set to zero. The depth of the image to be recognized as if protruding from the display unit 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 larger than aa. 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.

<Description of Fig. 8>

8 is a diagram referred to for describing an operation control method of an image display apparatus according to an embodiment of the present invention. When the sound adjustment command is input, the image display apparatus 100 of the present exemplary embodiment may display the sound information currently set in the image display apparatus 100 using the 3D object. The image display apparatus 100 may change the color, size, shape, position, or depth of the 3D object to correspond to the input sound adjustment command. The 3D object may be in the shape of a sound output means. For example, the 3D object may be a 3D object expressed in the shape of a speaker. The user recognizes the 3D object consisting of the left eye image and the right eye image by viewing the left eye image and the right eye image constituting the 3D object through the left eye and the right eye, respectively.

The user may input a sound adjustment command to the image display apparatus 100 (S110). For example, a user may input a sound adjustment command to the image display apparatus 100 using the remote control apparatus 200 that may transmit a control command to the image display apparatus 100. In addition, the user may input a sound adjustment command to the image display apparatus 100 using a button such as a hard key provided in the image display apparatus 100.

In addition, the sound adjustment command includes a command for adjusting the delay time of the sound output to each sound output means from the image display apparatus 100 connected to at least two sound output means. The sound adjustment command may include a sound balance adjustment command for adjusting the sound output level output from the image display apparatus 100 connected to at least two sound output means to each sound output means. In addition, the sound adjustment command includes all kinds of commands for adjusting the output of the sound being output from the image display apparatus 100.

The controller 170 of the image display apparatus 100 determines a sound setting of the current image display apparatus 100 when a sound adjustment command is input (S120). The sound setting of the current image display apparatus 100, which may be determined by the controller 170, includes an output level of sound output from the sound output means connected to the image display apparatus 100. In addition, when the image display apparatus 100 and at least two sound output means are connected, the controller 170 may determine a balance or sound delay time of the sound output level output to each sound output means. In addition, the number of sound output means connected to the image display apparatus 100 and the position of each sound output means may be determined.

The controller 170 outputs an image signal to the display unit 180 so that the user can recognize the 3D object corresponding to the current sound setting (S130). The display unit 180 displays at least two multi-view images constituting the 3D object based on the image signal output from the controller 170. The controller 170 may output the 3D image signal according to a predetermined 3D image signal format such as side by side and top down to the display unit 180 so that the user may recognize the 3D object through the display unit 180.

The controller 170 changes the color, size, shape, position, or depth of the sound output means 3D object to correspond to the adjustment sound information included in the sound adjustment command input by the user (S140). That is, the controller 170 changes the 3D image signal output to the display unit 180 to change the color, size, shape, and shape of the 3D object of the audio output means recognized by the user through the multi-view image displayed on the display unit 180. Allow position or depth to change.

For example, the user may input a volume increase command to the image display apparatus 100 using the remote control apparatus 200 that can transmit a control command to the image display apparatus 100. The controller 170 determining that the volume increase command is input may change the 3D image signal output to the display unit 180 so that the size of the sound output means 3D object recognized by the user increases.

As another example, the user may adjust the balance of the sound output to the left and right sound output means connected to the image display apparatus 100. In this case, the controller 170 outputs the 3D image signal to the display unit 180 so that the user can recognize the 3D object corresponding to the left and right sound output means connected to the image display apparatus 100. The display unit 180 displays a multi-view image constituting a sound output means 3D object according to the 3D image signal output from the controller 170. The controller 170 may process the 3D image signal output to the display unit 180 to change the size of the sound output means 3D object recognized by the user according to the adjusted balance. The user may recognize that the balance of the sound output to the left and right sound output means connected to the image display apparatus 100 is adjusted by changing the size of the sound output means 3D object.

9 is a view referred to for explaining the operation method of the image display device according to the present invention.

The image display apparatus 100 of this embodiment is connected to at least two sound output means. The display unit 180 of the image display apparatus 100 displays a multi-view image constituting at least two sound output means 3D objects (S210). The sound output means 3D object recognized by the user through the display unit 180 corresponds to the sound output means to which the image display apparatus 100 is connected. For example, the number of sound output means 3D objects may correspond to the number of sound output means to which the image display apparatus 100 is connected. Also, the display position or depth of the sound output means 3D object may correspond to the position of the sound output means to which the image display apparatus 100 is connected.

You can print

The controller 170 of the image display apparatus 100 determines whether a command for selecting one of the sound output means 3D objects recognized by the user is input through the multi-view image displayed on the display 180 (S220). The sound output means 3D object selection command may be input to the image display apparatus 100 through manipulation of up, down, left, and right movement buttons provided in the remote control apparatus 200. In addition, when the image display apparatus 100 displays a cursor corresponding to a signal transmitted from the remote control apparatus 200, the controller 100 may determine that the sound output means 3D object in which the cursor stays for a predetermined time or more is selected. have.

The controller 170 of the image display apparatus 100 changes the 3D image signal output to the display unit 180 so that the display state of the sound output means 3D object corresponding to the selection command is changed (S230). For example, the controller 170 of the image display apparatus 100 may determine a sound output means 3D object corresponding to a selection command among a plurality of sound output means 3D objects corresponding to the sound output means to which the image display apparatus 100 is connected. The 3D image signal output to the display unit 180 may be changed to change the color. In addition, the controller 170 of the image display apparatus 100 may change the contour of the sound output means 3D object corresponding to the selection command so that the user may recognize that the corresponding sound output means 3D object is selected.

The controller 170 of the image display apparatus 100 determines whether a sound adjustment command is input to the image display apparatus 100 (S240). The sound adjustment command may be a command for adjusting the sound output level of the sound output means corresponding to the selected sound output means 3D object. In addition, the sound adjustment command may be a command for adjusting the display position or depth of the selected sound output means 3D object.

The controller 170 of the image display apparatus 100 may change the sound output means 3D object to correspond to the sound adjustment command determined as being input (S250). For example, when a command for increasing or decreasing the sound output level of the sound output means corresponding to the selected sound output means 3D object is input, the controller 170 may be configured to the adjusted sound output level of the selected sound output means 3D object. The 3D video signal output to the display unit 180 may be changed to correspond. In addition, the controller 170 may adjust the sound output level output to the sound output means corresponding to the selected sound output means 3D object so as to correspond to the sound adjustment command determined as input.

As another example, when a position movement command of the selected sound output means 3D object is input, the controller 170 may display the display unit (eg, the display position or the depth of the selected sound output means 3D object) to correspond to the position movement command determined to be input. The 3D video signal output to the 180 may be changed. In addition, the controller 170 may change the sound output level or the delay time and the like output to the sound output means corresponding to the selected sound output means 3D object to correspond to the sound output means 3D object whose display position or depth is changed.

As described above, the image display apparatus 100 changes the color, size, shape, position or depth of the sound output means 3D object corresponding to the selection command so as to correspond to the input sound adjustment command. In addition, according to the sound adjustment command, the sound output to the sound output means connected to the actual video display device 100 is adjusted.
