FIG. 5B illustrates an operation of the 3D glass 195, in particular, the polarization glass 195 when the formatter 360 arranges and outputs the side-by-side format among the formats of FIG. 4. Meanwhile, the 3D glass 195 applied in FIG. 5B may be a shutter glass, and the shutter glass may be operated as a polarized glass by keeping both the left eye glass and the right eye glass open. .

Meanwhile, the formatter 360 may convert the 2D video signal into a 3D video signal. For example, an edge or selectable object may be detected within the 2D image signal according to a 3D image generation algorithm, and an object or selectable object according to the detected edge may be separated into a 3D image signal and generated. Can be. 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 figure, a 3D processor (not shown) for processing a 3D effect signal may be further disposed after the formatter 360. The 3D processor (not shown) may process brightness, tint, and color adjustment of an image signal to improve 3D effects. For example, signal processing may be performed to sharpen the near distance and blur the far distance. Meanwhile, the functions of the 3D processor may be merged into the formatter 360 or merged into the image processor 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.

Also, the audio processor (not shown) in the controller 170 may process a base, a treble, a volume control, and the like.

The data processor (not shown) in the controller 170 may perform data processing of the demultiplexed data signal. For example, when the demultiplexed data signal is an encoded data signal, it may be decoded. The encoded data signal may be EPG (Electronic Progtam Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted in each channel.

In FIG. 3, the signals from the OSD generator 340 and the image processor 320 are mixed in the mixer 345 and then 3D processed in the formatter 360, but the present invention is not limited thereto. May be located after the formatter. That is, the output of the image processor 320 is 3D processed by the formatter 360, and the OSD generator 340 performs 3D processing together with OSD generation, and then mixes each processed 3D signal by the mixer 345. It is also possible.

Meanwhile, a block diagram of the controller 170 shown in FIG. 3 is a block diagram for one embodiment of the present invention. Each component of the block diagram may be integrated, added, or omitted according to the specification of the controller 170 that is actually implemented.

In particular, the frame rate converter 350 and the formatter 360 are not provided in the controller 170, but may be provided separately.

6 is a diagram illustrating various scaling methods of 3D video signals according to an embodiment of the present invention.

Referring to the drawings, in order to increase the 3D effect, the controller 170 may perform 3D effect signal processing. Among them, in particular, the size or tilt of the 3D object in the 3D image may be adjusted.

As shown in FIG. 6A, the 3D image signal or the 3D object 510 in the 3D image signal may be enlarged or reduced 512 as a whole at a predetermined ratio, and as shown in FIGS. 6B and 6C. The 3D object may be partially enlarged or reduced (trapezoidal shapes 514 and 516). In addition, as illustrated in FIG. 6D, 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. 6 (b) or 6 (c), the length difference between the parallel sides of the trapezoidal shapes 514 and 516 increases, or as shown in FIG. 6 (d), the rotation angle is increased. 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 360. Alternatively, it may be performed by the scaler 235 in the image processor 320. On the other hand, the OSD generation unit 340, it is also possible to create the object in the shape as shown in Figure 6 to generate the OSD to emphasize the 3D effect.

On the other hand, although not shown in the figure, as a signal processing for a three-dimensional effect, in addition to the size adjustment or tilt adjustment illustrated in Figure 6, the brightness (brightness), tint (Tint) and It is also possible to perform signal processing such as color adjustment. For example, signal processing may be performed to sharpen the near distance and blur the far distance. Meanwhile, the signal processing for the 3D effect may be performed in the controller 170 or may be performed through a separate 3D processor. In particular, when performed in the controller 170, it may be performed in the formatter 360 together with the above-described size adjustment or tilt adjustment, or may be performed in the image processor 320.

FIG. 7 is a diagram illustrating an image formed by a left eye image and a right eye image, and FIG. 8 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. 7, 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. 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 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.

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 exemplary embodiment of the present invention, the distance between the display 180 and the objects 615, 625, 635, and 645 recognized by the user is expressed as a depth. Accordingly, the depth when the user is recognized as if it is located behind the display 180 has a negative value (-), and the depth when the user is recognized as if it is located before the display 180. (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. 8, the distance a between the left eye image 701 and the right eye image 702 of FIG. 8A is the distance between the left eye image 701 and the right eye image 702 shown in FIG. 8B. If (b) is smaller, it can be seen that the depth a 'of the 3D object of FIG. 8 (a) is smaller than the depth b' of the 3D object of FIG. 8 (b).

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.

9 is a diagram illustrating a control method of the remote controller of FIG. 1.

As illustrated in FIG. 9A, a pointer 205 corresponding to the remote controller 200 is displayed on the display 180.

The user can move or rotate the remote control device 200 up and down, left and right (FIG. 9B) and front and rear (FIG. 9C). The pointer 205 displayed on the display 180 of the image display device corresponds to the movement of the remote controller 200. The remote control apparatus 200 may be referred to as a spatial remote controller because the pointer 205 is moved and displayed according to the movement in the 3D space as shown in the figure.

FIG. 9B illustrates that when the user moves the remote control apparatus 200 to the left side, the pointer 205 displayed on the display 180 of the image display apparatus also moves to the left side correspondingly.

Information about the movement of the remote control device 200 detected through the sensor of the remote control device 200 is transmitted to the image display device. The image display device may calculate the coordinates of the pointer 205 from the information about the movement of the remote controller 200. The image display device may display the pointer 205 to correspond to the calculated coordinates.

FIG. 9C illustrates a case in which the user moves the remote control apparatus 200 away from the display 180 while pressing a specific button in the remote control apparatus 200. As a result, the selection area in the display 180 corresponding to the pointer 205 may be zoomed in and enlarged. On the contrary, when the user moves the remote controller 200 to be closer to the display 180, the selection area in the display 180 corresponding to the pointer 205 may be zoomed out and reduced. On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 approaches the display 180, the selection area may be zoomed in.

On the other hand, while pressing a specific button in the remote control device 200 can recognize the up, down, left and right movement. That is, when the remote control device 200 moves away from or near the display 180, the up, down, left and right movements are not recognized, and only the front and back movements can be recognized. In a state where a specific button in the remote controller 200 is not pressed, only the pointer 205 moves according to the up, down, left, and right movements of the remote controller 200.

Meanwhile, the moving speed or the moving direction of the pointer 205 may correspond to the moving speed or the moving direction of the remote control apparatus 200.

When the user input unit 835 includes a touch screen, the user may input a command related to the image display apparatus 100 to the remote controller 200 by touching a soft key of the touch screen. In addition, the user input unit 835 may include various kinds of input means that the user can operate, such as a scroll key or a jog key, and the present embodiment does not limit the scope of the present invention.

The sensor unit 840 may include a gyro sensor 841 or an acceleration sensor 843. The gyro sensor 841 may sense information about the movement of the remote controller 200.

For example, the gyro sensor 841 may sense information about an operation of the remote controller 200 based on the x, y, and z axes. The acceleration sensor 843 may sense information about a moving speed of the remote controller 200. Meanwhile, a distance measuring sensor may be further provided, whereby the distance with the display 180 may be sensed.

The output unit 850 may output a video or audio signal corresponding to a manipulation of the user input unit 835 or corresponding to a signal transmitted from the image display apparatus 100. The user may recognize whether the user input unit 835 is manipulated or whether the image display apparatus 100 is controlled through the output unit 850.

For example, the output unit 850 may be an LED module 851 that is turned on when the user input unit 835 is manipulated or a signal is transmitted to or received from the image display device 100 through the wireless communication unit 825, or a vibration module generating vibration. 853), a sound output module 855 for outputting sound, or a display module 857 for outputting an image.

The power supply unit 860 supplies power to the remote control device 200. The power supply unit 860 may reduce power waste by stopping the power supply when the remote controller 200 does not move for a predetermined time. The power supply unit 860 may resume power supply when a predetermined key provided in the remote control apparatus 200 is operated.

The storage unit 870 may store various types of programs, application data, and the like required for controlling or operating the remote control apparatus 200.

11 is a flowchart illustrating a method of operating an image display apparatus according to an embodiment of the present invention, and FIGS. 12A to 16C are diagrams for describing various examples of the method of operating the image display apparatus of FIG. 11.

Referring to FIG. 11, first, before the operation 1110 (S1110), although not shown in the figure, the access road enters the 3D mode. The 3D mode may be manually entered by user input. For example, when a hot keey for entering the 3D mode is provided in the remote control apparatus 200 or the local key (not shown), the 3D mode may be entered by the operation of the hot key.

The OSD generator 340 in the controller 170 may generate an OSD. In particular, the OSD generator 340 may generate a 2D image having a plurality of 2D OSDs. In this case, the OSD generated by the OSD generator 340 may be 2D OSD.

For example, 2D OSD is a 2D Graphic Gser Interface (GUI) and may be a menu, a widget, an icon, an EPG, a pointer, text, a picture, or the like.

Next, a first depth is set in the first 2D OSD among the plurality of 2D OSDs provided in the 2D image, and a second depth is set in the second 2D OSD (S1110).

The formatter 360 receives a plurality of 2D OSDs included in the 2D image generated by the OSD generator 340. The first depth is set in the first 2D OSD, and the second depth is set in the second 2D OSD. The first depth and the second depth may be different depths.

According to an embodiment of the present invention, when the first 2D OSD and the second 2D OSD overlap each other, the depths are set differently so that they are displayed according to different depths.

For example, as shown in FIG. 12A, when the second 2D OSD 1230 overlaps the first 2D OSD 1220, the formatter 360 may layer information about each 2D OSD. ). Such layering information may be stored in the OSD generator 340 or in the storage 140. Alternatively, when receiving each OS in the formatter 360, the layering information may be received together.

Such layering information may be relative location information, not absolute location information. For example, the location information of the second 2D OSD 1230 may be +5 greater than that of the first 2D OSD 1220.

The formatter 360 may infer the layering information by using the storage location information of the first 2D OSD 1220 and the storage location information of the second 2D OSD 1230. For example, when the storage location information of the first 2D OSD 1220 is binary 1001 and the storage location information of the second 2D OSD 1230 is binary 1110, the location information difference is binary 101 (ie, , Decimal number 5), can infer a layering information difference of +5.

Thus, for example, the formatter 360 may set the depth of the first 2D OSD 1220 to 5 and the depth of the second 2D OSD 1230 to 10.

12B illustrates that the depth of the first 2D OSD 1220 is set to z1 compared to the 2D plane 1215, and the depth of the second 2D OSD 1230 is set to Z2 compared to the 2D plane 1215. Example of setting to. That is, it illustrates that the depth of the second 2D OSD 1230 is larger.

The formatter 360 may vary the difference between the first depth of the first 2D OSD 1220 and the second depth of the second 2D OSD 1220 according to the overlapping area. For example, as the overlapping area increases, the depth difference between the first 2D OSD 1220 and the second 2D OSD 1230 may be set to be smaller. Alternatively, as the overlapping area becomes smaller, the depth difference between the first 2D OSD 1220 and the second 2D OSD 1230 may be increased.

Meanwhile, in addition to the first 2D OSD and the second 2D OSD, the formatter 360 has a difference between the first depth and the second depth when there are additional 2D OSDs, that is, as the number of 2D OSDs increases. Can be set to be smaller.

As the number of 2D OSDs increases, as the depth between each 2D OSDs increases, the 2D OSDs with stereo effect cannot be represented.As the number of 2D OSDs increases, the number of 2D OSDs increases. It is preferable to set so that depth may become small. Specifically, the formatter 360 may be set such that the difference between the first depth of the first 2D OSD and the second depth of the second 2D OSD 1220 is small. This will be described later with reference to FIGS. 14A to 14C.

In the meantime, when the first 2D OSD and the second 2D OSD of the plurality of 2D OSDs do not overlap, the formatter 360 is proportional to the sizes of the first 2D OSD and the second 2D OSS, The depth and the second depth can be set. For example, the depth of the larger first 2D OSD may be set to be greater than the depth of the second 2D OSD. In this way, by setting the depth of the 2D OSD in proportion to the size, it is possible to give different three-dimensional feeling to each OSD. As a result, the user's ease of use can be improved.

Next, the first 2D OSD is converted into the first 3D OSD based on the first depth, and the second 2D OSD is converted into the second 3D OSD based on the second depth (S1120).

The formatter 360 converts the first 2D OSD into the first 3D OSD based on the set first depth of the first 2D OSD 1220, and sets the second set of the second 2D OSD 1230. Based on the depth, convert the second 2D OSD into a second 3D OSD.

Specifically, the formatter 360 arranges the first 2D OSD 1220 and the second 2D OSD 1230 as the first left eye 2D OSD and the second left eye 2D OSD within the first left eye image. do. The formatter 360 also arranges the first 2D OSD 1220 and the second 2D OSD 1230 as the first right eye 2D OSD and the second right eye 2D OSD in the first right eye image. .

FIG. 13A illustrates a 2D image 1210 having a first 2D OSD 1220 and a second 2D OSD 1230, and FIG. 13B illustrates a left eye image L and a right eye image R. FIG.

The left eye image L of FIG. 13B includes a 2D plane 1215 that is a background image, a first left eye 2D OSD 1225, and a second left eye 2D OSD 1235.

The right eye image R of FIG. 13B includes a 2D plane 1218 that is a background image, a first right eye 2D OSD 1228, and a second right eye 2D OSD 1238.

At this time, the first left eye 2D OSD 1225 in the left eye image L and the first right eye 2D OSD 1228 in the right eye image R are respectively separated by the first parallax D1 according to the set first depth Z1. Has (Disparity)

In addition, the second left eye 2D OSD 1235 in the left eye image L and the first right eye 2D OSD 1238 in the right eye image R may have a second parallax D2 according to the set second depth Z2. Has

The combination of the first left eye 2D OSD 1225 and the first right eye 2D OSD 1228 in the left eye image L and the right eye image R may be referred to as a first 3D OSD 1260. The combination of the first left eye 2D OSD 1235 and the first right eye 2D OSD 1238 in the left eye image L and the right eye image R may be referred to as a first 3D OSD 1270.

Next, a 3D image including the first 3D OSD and the second 3D OSD is displayed (S1130). The display 180 displays a 3D image including the first 3D OSD and the second 3D OSD converted by the formatter 360.

For example, the left eye image L and the right eye image R may be displayed at different times according to the frame sequential format of FIG. 4C. That is, the 3D image may be displayed in the active mode. For example, the display 180 may display the left eye image L at the first time T = t1 and display the right eye image R at the second time T-t2. Accordingly, the user may view the 3D image using the shutter glasses in which the left eye glass is turned on at the first time T = t1 and the right eye glass is turned on at the second time T-t2.

Meanwhile, as another example, the left eye image L and the right eye image R may be separately displayed for each line according to the interlace format of FIG. 4D. That is, the 3D image may be displayed in the passive mode. For example, the display 180 may display a left eye image L on odd lines and a right eye image on even lines. To this end, the left eye polarization pattern may be disposed in an area corresponding to the odd lines of the display 180, and the right eye polarization pattern may be disposed in an area corresponding to the even lines. Accordingly, the user can view a 3D image by using a polarizing glass having a left eye polarizing glass in which only the left eye image is polarized and a right eye polarizing glass in which only the right eye image is polarized.

12C illustrates that the 3D image 1250 is displayed on the display 180. That is, the first 3D OSD 1260 and the second 3D OSD 1270 have different depths and are displayed as a stereoscopic image. In the figure, the second 3D OSD 1270 has a greater depth and illustrates what appears to protrude further. In this way, by setting and displaying different depths for each OSD, different three-dimensional effects can be provided. As a result, the user's ease of use can be improved.

Meanwhile, the first 3D OSD 1260 of FIG. 12C may be a first menu, and the second 3D OSD 1270 may be a second menu. Alternatively, the first 3D OSD 1260 of FIG. 12C may be a menu, and the second 3D OSD 1270 may be a pointer (205 of FIG. 9) corresponding to the movement of the remote controller 200. Alternatively, the first 3D OSD 1260 of FIG. 12C may be a menu, and the second 3D OSD 1270 may be a widget indicating time or weather.

14A to 14C illustrate 3D image display when 2D OSD is further increased as compared to FIGS. 12A to 12C.

Referring to the drawing, the 2D image 1410 may include three 2D OSDs 1420, 1430, and 1440. 14A illustrates that a second 2D OSD 1430 overlaps on a first 2D OSD 1420, and a third 2D OSD 1440 overlaps on a second 2D OSD 1430. .

Accordingly, the formatter 360 sets depths using the layering information of each of the 2D OSDs 1420, 1430, and 1440.

As described above, the formatter 360 stores the storage location information of the first 2D OSD 1420, the storage location information of the second 2D OSD 1430, and the storage location information of the third 2D OSD 1440. By using the layering information can be inferred. For example, the storage location information of the first 2D OSD 1420 is binary 01001, the storage location information of the second 2D OSD 1430 is binary 01110, and the storage of the third 2D OSD 1440. When the location information is a binary number 10011, since the location information difference of each 2D OSD is binary 101 (that is, decimal number 5), the layering information difference of +5 can be inferred.

The formatter 360 sets, for example, the depth of the first 2D OSD 1420 to 5, the depth of the second 2D OSD 1430 to 8, and the third 2D OSD 1440. You can set the depth of to 12.

The storage location information of the first 2D OSD 1420 and the storage location information of the second 2D OSD 1430 are stored in the first 2D OSD 1220 as described in the description of FIGS. 12A to 12C. It can be seen that the location information is the same as the storage location information of the second 2D OSD 1230.

However, the formatter 360 may set the depth of the first 2D OSD 1420 to 5 and set the depth of the second 2D OSD 1430 to 8 instead of 10. This takes into account the depth setting of the third 2D OSD 1440. As the number of 2D OSDs increases as the number of 2D OSDs increases, as the depth between each 2D OSS increases, the 2D OSDs with stereo effect cannot be represented. It is preferable to set so that the depth between SDs may become small.

 In FIG. 14B, a depth difference between the first 2D OSD 1420 and the second 2D OSD 1430 is illustrated as ΔZ2, and a depth difference between the second 2D OSD 1430 and the third 2D OSD 1440 is illustrated. It demonstrates as (DELTA) Z3.

Among these, ΔZ 2, which is a difference in depth between the first 2D OSD 1420 and the second 2D OSD 1430 of FIG. 14B, is the first 2D OSD 1220 and the second 2D OSD 1230 of FIG. 12B. It can be seen that compared to ΔZ1, which is the difference in depths of, is smaller.

14C illustrates that the 3D image 1450 is displayed on the display 180. That is, the first 3D OSD 1460, the second 3D OSD 1470, and the third 3D OSD 1480 have different depths and are displayed as stereoscopic images. In the figure, the second 3D OSD 1470 has a greater depth than the first 3D OSD 1460 and the third 3D OSD 1480 has a greater depth than the second 3D OSD 1470. Illustrate that. In this way, by setting and displaying different depths for each OSD, different three-dimensional effects can be provided. As a result, the user's ease of use can be improved.

15A to 15C illustrate a 3D image display by giving different depths and tilting angles to 2D OSD.

Referring to the drawing, the 2D image 1510 may include two 2D OSDs 1520 and 1530. FIG. 15A illustrates that the second 2D OSD 1530 overlaps on the first 2D OSD 1520.

First, similar to FIG. 13B, the left eye image L includes a 2D plane 1515 that is a background image, a first left eye 2D OSD 1525, and a second left eye 2D OSD 1535.

The right eye image R of FIG. 13B includes a 2D plane 1518 that is a background image, a first right eye 2D OSD 1528, and a second right eye 2D OSD 1538.

At this time, the first left eye 2D OSD 1525 in the left eye image L and the first right eye 2D OSD 1528 in the right eye image R are respectively separated by a first parallax D1 according to the set first depth Z1. Has (Disparity)

In addition, the second left eye 2D OSD 1535 in the left eye image L and the first right eye 2D OSD 1538 in the right eye image R may have a second parallax D2 according to the set second depth Z2. Has

On the other hand, in order to improve the stereoscopic effect, as shown in Figure 6, it is possible to perform the tilt control of each 2D OSD. In other words, it may be referred to as tilting angle adjustment. That is, as shown in Fig. 6b, the quadrangles are changed in a trapezoid shape to further enhance the steric effect.

At this time, the larger the tilting angle, that is, the rectangular the trapezoidal shape, the greater the steric effect.

In an embodiment of the present invention, a first tilting angle is set in the first 2D OSD and a second tilting angle is set in the second 2D OSD. This tilt angle setting may be performed by the formatter 360 as described above.

In particular, the tilt angle may be set in proportion to the depth. Specifically, the greater the depth, the greater the tilting angle, and the more the three-dimensional effect can be maximized.

Here, the tilting angle may mean an angle between the horizontal line and the trapezoid as illustrated in FIG. 15B. In FIG. 15B, the tilting angle of the first left eye 2D OSD 1525 in the left eye image L and the tilting angle of the first right eye 2D OSD 1528 in the right eye image R are set to θ1, and the left eye image Setting the tilting angle of the second left eye 2D OSD 1535 in (L) and the tilting angle of the second right eye 2D OSD 1538 in the right eye image R to θ2 is illustrated. At this time, in consideration of the set depth, it is preferable that θ2 is larger than θ1.

By the depth setting and the tilting angle setting, FIG. 15C illustrates that the 3D image 1550 is displayed on the display 180. That is, the first 3D OSD 1560 and the second 3D OSD 1570 have different depths, have different tilting angles, and are displayed as stereoscopic images. In this way, by setting and displaying different depths and tilting angles for each OSD, different three-dimensional effects can be provided. As a result, the user's ease of use can be improved.

The formatter 360 may set the tilting angle to be larger as the position of the 2D OSD is closer to the outside of the 2D image. By assigning a larger tilt angle to the 2D OSD close to the perimeter, the stereo effect can be further maximized.

16A to 16C illustrate 3D image display when a plurality of 2D OSDs are spaced apart from each other without overlapping.

Referring to the drawing, the 2D image 1610 may include two 2D OSDs 1620 and 1530. FIG. 16A illustrates that the first 2D OSD 1620 and the second 2D OSD 1630 are spaced apart from each other without overlapping.

When the first 2D OSD and the second 2D OSD of the plurality of 2D OSDs do not overlap, the formatter 360 is proportional to the size of the first 2D OSD and the second 2D OSD, and the first depth and the second depth. The second depth may be set.

Referring to FIG. 16A, it can be seen that the size of the first 2D OSD 1620 is larger than the size of the second 2D OSD 1630. Accordingly, the formatter 360 may set a greater depth to the first 2D OSD 1620.

16B sets the depth of the first 2D OSD 1620 to zm relative to the 2D plane 1615 and the depth of the second 2D OSD 1630 to Zn relative to the 2D plane 1615. Example of setting. That is, it illustrates that the depth of the first 2D OSD 1630 is larger.

With this depth setting, FIG. 16C illustrates that the 3D image 1650 is displayed on the display 180. That is, the first 3D OSD 1660 and the second 3D OSD 1670 have different depths and are displayed as a stereoscopic image. In this way, even when each OSD does not overlap with each other, different three-dimensional feelings can be provided by setting and displaying different depths. As a result, the user's ease of use can be improved.
