Then, the left eye image signal and the right eye image signal may be scaled into one or more of various examples shown in FIG. 5 and output in a predetermined format as shown in FIG. On the other hand, the scaling may be performed before or after the output format is formed.

The formatter 175 receives the OSD signal of the OSD generating unit 174 or the OSD signal mixed with the decoded video signal, separates the 3D video signal, and separates the 3D video signal into a plurality of viewpoint video signals . For example, the 3D image signal may be separated into a left eye image signal and a right eye image signal, and the separated left eye image signal and right eye image signal may be scaled as shown in FIG. 5 and output in a predetermined format shown in FIG. .

Meanwhile, the OSD generating unit 174 may scale the 3D image or the 3D object generated based on the OSD signal to be output. When the OSD generating unit 174 directly performs scaling on the OSD, the formatter 175 does not need to perform scaling on the OSD. In this case, the OSD generating unit 174 not only generates the OSD signal, but scales the OSD signal according to the depth or inclination of the OSD, and further outputs the OSD signal in a suitable format. The format of the OSD signal output from the OSD generation unit 174 may be any of various formats of the left eye image signal, the right eye image signal, or the left eye image and the right eye image, as shown in FIG. At this time, the output format is the same as the output format of the formatter 175.

FIG. 6 is a view illustrating a depth of a 3D image or a 3D object according to an exemplary embodiment of the present invention.

According to the embodiment of the present invention described above, the 3D image is composed of multi-view images, and the multi-view image can be exemplified as the left eye image and the right eye image. In this case, FIG. 6 shows a position where a position recognized as an image is changed according to the interval between the left eye image and the right eye image. Referring to FIG. 6, the three-dimensional sensation or the perspective sensation of the image to be felt by the user according to the interval or parallax between the left eye image and the right eye image will be described.

In Fig. 6, a plurality of images or a plurality of objects having different depths are shown. 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 is composed of the first left eye image signal and the first right eye image signal. 6 shows the positions of the first right eye image based on the first left eye image signal and the first right eye image signal on the display unit 180 based on the first left eye image signal. 6 shows an interval between the first left-eye image and the first right-eye image displayed on the display unit 180. FIG. The description of the first object may be applied to the second to fourth objects. Hereinafter, for convenience of explanation, the left eye image and the right eye image displayed on the display unit 180 for one object, and the interval set between the two images and the serial numbers of the objects will be described in unison.

The first object 615 is composed of 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 the elongation that connects the left eye 601 and the first left eye image 611 and that the image is formed at a point where an extension line connecting the right eye 603 and the first right eye image 603 intersects. 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 can be represented by a depth. In this embodiment, the 3D object recognized by the user has a negative value (-) as if it is positioned behind the display unit 180. Therefore, the depth of the first object 615 has a negative value.

The second object 625 is composed of a second right eye image 623 (represented by R2) and a second left eye image 621 (represented by L2). The second right-eye image 623 and the second left-eye image 621 are displayed at the same position on the display unit 180 according to the present embodiment. The interval between the second right eye image 623 and the second left eye image 621 is zero. The user recognizes that an extension line connecting the left eye 601 and the second left eye image 621 and an extension line connecting the right eye 603 of the user and the second right eye image 623 intersect with each other. Accordingly, the user recognizes that the second object 625 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 recognized as being protruding toward the user from the display unit 180. [ Furthermore, it is possible to explain that the degree of perspective or stereoscopic feeling perceived by the user varies with the change in the interval between the left eye image and the right eye image, with reference to examples of the third object 635 and the fourth object 645.

The third object 635 is composed of a third right eye image 633 (represented by R3) and a third left eye image (represented by 631 and L3). And 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 image is formed at an intersection of an extension line connecting the left eye 601 and the third left eye image 631 and an extension line of the right eye 603 and the third right eye image 633. Accordingly, the user recognizes that the third object 625 is positioned ahead of the display unit 180, i.e., nearer to the user. That is, the third object 635 is recognized by the user as if the third object 635 is projected from the display unit 180 toward the user. In this embodiment, the 3D object recognized by the user has a positive value (+), as in the case where the 3D object is positioned ahead of the display unit 180. Thus, the depth of the third object 635 has a positive value.

The fourth object 645 is composed of a fourth right eye image 643 (represented by R4) and a fourth left eye image (represented by 641 and L4). And 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 image is formed at an intersection of an extension line connecting the left eye 601 and the fourth left eye image 641 and an extension line of the right eye 603 and the fourth right eye image 643. Therefore, the user recognizes that the fourth object 645 is positioned closer to the user than the third object 635, as well as located in front of the display unit 180, i.e., closer to the user. That is, the fourth object 645 is perceived by the user as if it is positioned to protrude from the display unit 180 and the third object 635 toward the user. The fourth object 645 has a depth amount value.

The image display apparatus 100 can recognize the user as if the object composed of the left eye image and the right eye image are positioned behind the display unit 180 by adjusting the positions of the left eye image and the right eye image displayed on the display unit 180 So that the user is perceived as if it is located. In addition, the image display apparatus 100 can control the depth sense of the object composed of the left eye image and the right eye image by adjusting the display intervals of the left eye image and the right eye image displayed on the display unit 180. [

That is, according to the description with reference to FIG. 6, whether the depth of an object composed of a left eye image and a 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 Is determined. As described above, an object having a positive value (+) in depth is an object recognized by the user as if it is located protruding from the display unit 180. Also, an object whose depth has a negative value (-) is an object recognized by the user as if it is positioned behind the display unit 180.

Referring to FIG. 6, the depth of the object, that is, the distance between the point at which the 3D image is recognized by the user and the display unit 180 varies according to the absolute value of the interval between the left eye image and the right eye image can do.

7,

FIG. 7 is a view illustrating a state in which the 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 changes depending on the interval between the left eye image 701 and the right eye image 702 displayed on the display unit 180. In this embodiment, the depth of the display unit 180 is set to zero. The depth of the image recognized as being projected from the display unit 180 is set to have a positive value.

An interval between the left eye image 701 and the right eye image 702 shown in FIG. 7A is a. The interval between the left eye image 701 and the right eye image 702 shown in FIG. 7 (b) is b. Where b is greater than aa. That is, the interval between the left eye image 701 and the right eye image 702 in the example shown in FIG. 7 (b) is wider than the example shown in FIG. 7 (a).

In this case, as described with reference to Fig. 6, the depth feeling of the 3D image or the 3D object shown in Fig. 7B is larger than the depth feeling of the 3D image or 3D object shown in Fig. 7A . In each case, when the depth sense is expressed numerically and denoted by a 'and b', respectively, it can be understood that the relationship of a '<b' is also established according to the relation of a <b. That is, when it is desired to implement a 3D image which is seen as a protruding, the depth feeling expressed by the widening or narrowing of the interval between the left eye image 701 and the right eye image 702 may become larger or smaller.

[ The control unit 170 which has determined that the volume increase command has been input can change the 3D video signal output to the display unit 180 so that the size of the sound output means 3D object recognized by the user is increased.

As another example, the user can 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 plurality of view images constituting the sound output means 3D object according to the 3D image signal output from the controller 170. [ The control unit 170 may process 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 is changed according to the adjusted balance. The user can recognize that the balance of the sound output to the left and right sound output means connected to the image display apparatus 100 through the change of the size of the sound output means 3D object is adjusted.
