In addition, the audio processor 230 and a data processor may be further included.

The demultiplexer 210 demultiplexes an input stream. For example, when an MPEG-2 TS is input, it may be demultiplexed and separated into video, audio, and data signals, respectively. Here, the stream signal input to the demultiplexer 210 may be a stream signal output from the tuner 110, the demodulator 120, or the external device interface unit 130.

The image processor 220 may perform image processing of the demultiplexed image signal. To this end, the image processor 220 may include an image decoder 225 and a scaler 235.

The image decoder 225 decodes the demultiplexed image signal, and the scaler 235 performs scaling to output the resolution of the decoded image signal on the display 180.

As shown in FIG. 5A, the 3D video signal or the 3D object 510 in the 3D video signal may be enlarged or reduced 512 as a whole at a predetermined ratio, and as shown in FIGS. 5B and 5C. The 3D object may be partially enlarged or reduced (trapezoidal shapes 514 and 516). In addition, as shown in FIG. 5D, 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. 5 (b) or FIG. 5 (c), the length difference between the parallel sides of the trapezoidal shapes 514 and 516 increases, or as shown in FIG. 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 260. Alternatively, the image may be performed by the scaler 235 in the image processor 220. On the other hand, the OSD generation unit 240, it is also possible to generate the object in the shape as shown in Figure 5 to generate the OSD to emphasize the 3D effect.

FIG. 6 is a diagram illustrating an image formed by a left eye image and a right eye image, and FIG. 7 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. 6, 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. In this case, the user recognizes that an image is formed at an intersection point of 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. 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.

In this case, it is recognized that the fourth object 645 is projected ahead of the third object 635, that is, more protruding from the fourth object 635, which is the distance between the fourth left eye images 641 and L and the fourth right eye images 643 and R. d4) is larger than the distance d3 between the third left eye images 631 and L and the third right eye images 633 and R.

(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. 7, the distance a between the left eye image 701 and the right eye image 702 of FIG. 7A is the distance between the left eye image 701 and the right eye image 702 shown in FIG. 7B. When (b) is smaller, it can be seen that the depth b 'of the 3D object of FIG. 7 (b) is smaller than the depth a' of the 3D object of FIG. 7 (a).

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.

11A to 13B are views referred to for describing various examples of a method of operating an image display apparatus according to an exemplary embodiment of the present invention.

The controller 170 determines whether the display of the image display apparatus 100 is disposed horizontally on the ground (see FIG. 8B) by using the sensor unit 160 or the imaging unit 140. . For example, by using a gyro sensor in the sensor unit 160, whether the display 180 is horizontal to the ground is detected, and a detection signal may be input to the controller 170.

When the 3D image is displayed, the controller 170 may perform signal processing for the 3D effect when the display of the image display apparatus 100 is horizontally disposed on the ground.

Signal processing for the 3D effect is not performed when the display 180 of the image display apparatus 100 is disposed horizontally on the ground, but the display 180 of the image display apparatus 100 is disposed perpendicular to the ground. If so, it can be performed. Alternatively, when arranged vertically, 3D effect signal processing may be further enhanced than when arranged horizontally.

Meanwhile, FIG. 11A illustrates that the 3D object 1110 is displayed when the display 180 of the image display apparatus 100 is disposed perpendicular to the ground. When the user wears the 3D viewing apparatus 195, the user may confirm that the 3D object 1110 having a predetermined depth da, in particular, the first surface 1110a of the 3D object 1110 protrudes.

Next, FIG. 11B illustrates that the 3D object 1110 is displayed when the display 180 of the image display apparatus 100 is horizontally disposed on the ground. When the user wears the 3D viewing apparatus 195, the user may confirm that the 3D object 1120 having a predetermined depth db protrudes. In particular, compared to FIG. 11A, in addition to the first surface 1120a of the 3D object 1120, the second surface 1120b and the third surface 1120c may be recognized as protruding.

As such, when the display 180 of the image display apparatus 100 is horizontally disposed on the ground, since there is no graphic background surrounding the 3D object 1120, the hologram and Likewise, the 3D object 1120 may provide a vivid three-dimensional appearance as if standing.

Next, Figure 11C illustrates signal processing for the 3D effect.

When the display 180 of the image display apparatus 100 is disposed perpendicular to the ground, the controller 170 provides the object 1130 with a depth da due to the binocular disparity between the left eye image and the right eye image. . Accordingly, as shown in FIG. 11A, the 3D object 1110 is protruded to appear. In addition, the signal processing for the 3D effect may not be performed or may be performed insignificantly. Accordingly, the first region 1130a of the object 1130 does not perform scaling or tilt adjustment as described in FIG. 5.

On the other hand, when the display 180 of the image display apparatus 100 is horizontally disposed on the ground, the control unit 170 provides the object 1140 with the depth db due to the binocular disparity between the left eye image and the right eye image.

In addition, for the stereoscopic effect, a second region 1140b and a third region 1140c may be further added near the edge of the first region 1140a. In this case, the second region 1140b and the third region 1140c may be newly generated based on the edge of the first region 1140a.

Meanwhile, the above-described signal processing for the 3D effect may be performed by decoding an image of a new view and adding it to the original image. For example, when an input video signal is encoded into a multi-view video according to MVC (multi-view video coding) or the like, a view corresponding to the second area 1140b of FIG. 11C among the multi-view videos is included. Image of the view corresponding to the first region 1140a of FIG. 11C, and the image of the view corresponding to the first region 1140a of FIG. 11C. That is, it may add to the left eye image and the right eye image.

As a result, when the display 180 is disposed horizontally on the ground, the display 180 may be provided with an improved 3D object compared with the case where the display 180 is disposed perpendicular to the ground.

Meanwhile, the sensor unit 160 or the imaging unit 190 detects the position of the 3D viewing apparatus 195 for viewing 3D images. For example, the position sensor in the sensor unit 160 may sense the user or the 3D viewing device 195.

Meanwhile, the position of the 3D viewing apparatus 195 may be sensed by using the wireless communication unit 198 of the image display apparatus 100 that communicates with the wireless communication unit 930 of the 3D viewing apparatus 195.
