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.

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.

11 is a flowchart illustrating a method of operating an image display device according to an embodiment of the present invention, and FIGS. 12 to 18 are diagrams for describing various examples of the method of operating the image display device of FIG. 11.

Referring to FIG. 11, first, the receiving unit 105 receives electronic program guide (EPG) information including broadcast information such as a broadcast program name, a broadcast program start time, and an end time broadcasted in each broadcast channel. Receive. (S1110)

Here, the broadcast receiving unit 105 may include a tuner unit 110, a demodulator 120, and a network interface unit 130, and the electronic program guide information from the tuner unit 110 or the network interface unit 130. Can be received.

 Of course, if necessary, the broadcast receiving unit 105 may be designed to include the tuner unit 110 and the demodulator 120 but not include the network interface unit 130. It is also possible to design so as not to include the tuner unit 110 and the demodulation unit 120 while having. In this case, the electronic program guide information may be received by the tuner unit 110 or the network interface unit 130.

The controller 170 generates 3D format information of a broadcast program based on the received electronic program guide (EPG) information (S1120).

Subsequently, when there is an electronic program guide (EPG) display input through the user input interface unit 150 (S1130), the controller 170 controls to display the electronic program guide including the 3D format information on the display 180. (S1140)

That is, by distinguishing between the 2D broadcast program and the 3D broadcast program, and in the case of the 3D broadcast program, information related to the 3D broadcast is generated and displayed together with the electronic program guide, so that the user can intuitively grasp more information about the broadcast program. .

Therefore, 3D information is displayed on the electronic program guide, so that user convenience may be improved.

Meanwhile, in the step of generating 3D format information (S1120), the controller 170 may control to generate 3D format information by extracting 3D broadcast information included in the received electronic program guide (EPG) information.

That is, when 3D broadcast information of a content provider such as a broadcasting station is included in the electronic program guide (EPG) information, it may be extracted and used as 3D format information.

On the other hand, if 3D broadcast information is not included in the received EPG information, the controller 170 detects the 3D broadcast status and format using various known algorithms and methods, and then detects the 3D format information. Can be generated.

In addition, in the step of generating 3D format information (S1120), the controller 170 may generate the 3D format information including recommended 3D setting information based on the received electronic program guide (EPG) information. Can be controlled. Even in this case, if there is recommendation 3D setting information of a content provider such as a broadcasting station in the electronic program guide (EPG) information, it can be extracted and used as 3D format information.

The 3D format information may include recommended 3D setting information for each age, format, or genre of a corresponding program. In addition, the 3D format information may include recommended 3D setting information of a 3D depth and a convergence point of a corresponding program.

Even in this case, in the electronic program guide (EPG) information, recommended 3D setting information such as children's, adult's, multiple viewing, single viewing, etc. of content providers, such as broadcasting stations, and 3D depth and convergence settings If the information exists, it can be extracted and used as recommended 3D setting information.

In addition, different 3D image quality values may be recommended depending on the genre of the program, such as sports and movies.

Meanwhile, since the 3D image quality value of the broadcasting station is more accurate than the 3D image quality value detected by the image display device, the setting value provided by the broadcasting station may be given priority over the 3D image quality value detected by the image display device.

Meanwhile, the present invention further includes the receiving unit 105 receiving an image signal corresponding to a program included in the received electronic program guide (EPG) information, and in the generating of the 3D format information (S1120), the controller 170 may control to generate the 3D format information from the video signal.

The controller 170 may determine whether or not the 3D and the format are from the broadcast video signal input to the video display device.

 For example, when a 3D video flag or format information of a 3D video exists in a header of a stream of a received video stream, or 3D video metadata exists. In this case, it can be used.

In addition, the portion of the MPEG-2 standard video signal that is "reserved" can be examined to detect whether or not it is a 3D video. The controller in the image display apparatus 100 may check 2 bit data of the “reserved” portion and detect whether the image is a 3D image.

In the display step S1140, the controller 170 may control to display the 3D format information overlapping with the corresponding program.

In addition, the display state of a program item having the same 3D format information as the preset 3D format information may be displayed differently from the display state of another program.

Here, the preset 3D format information may be information registered in a 3D format preferred by a user and 3D format information frequently used.

Alternatively, the preset 3D format information may be 3D format information that the image display device can most effectively implement among 3D formats. For example, in the case of the shutter glass method, 3D broadcasting encoded in the frame sequential format and side by side format may be recommended, or in the polarization method, 3D broadcasting encoded in the top / bottom format may be recommended.

Since a conventionally provided electronic program guide (EPG) has a characteristic of simply organizing a broadcast station, it provides only information on a program that has been aired in the past and a program that is scheduled to be aired based on the current time.

However, in the present invention, when the EPG display command is input, the 3D information of the program in the EPG is checked, and accordingly the 3D information of at least one or more programs in the EPG is reflected and displayed.

Therefore, the user can more easily find the 3D broadcast program in the desired format.

The method of operating an image display apparatus according to an exemplary embodiment of the present invention may further include an interface unit receiving a selection input for the 3D format information and applying a setting included in the 3D format information.

It may include an object representing a format.

On the other hand, the format of the 3D video is a side by side format in which the left eye video signal L and the right eye video signal R are disposed left and right, and a top and bottom arranged up and down. Format, frame sequential arrangement in time division, interlaced format that mixes the left and right eye signals by line, and checker box that mixes the left and right eye signals by box Format and the like.

On the other hand, the above-described format of the 3D video is exemplary and it is obvious that other formats are possible. For example, frame packing (F / P) format, left and right eye images, with both eyes placed vertically up and down in a frame approximately doubled vertically, with a separate additional signal between the upper and lower images. A dual stream, a multi view format, etc., consisting of two scrims, may be possible.

The state may be different.

In addition, the display state may differ between 3D format information 1320 and 1330 including an object representing the 3D format according to the 3D format.

Meanwhile, as shown in FIG. 13B, display states of program items 1322 and 1332 corresponding to cases where the 3D format information 1321 and 1331 are different may be different from each other.

In addition, in the case of the program 1333 corresponding to the 3D format information 1331 that is the same as the preset 3D format information, as shown in FIG. 13C, the program item 1333 and / or the 3D format information 1331 are highlighted, and so on. A predetermined broadcast program may be recommended by being displayed so as to be distinguished from the item and 3D format information.

Meanwhile, the EPG screen according to the embodiment of the present invention may include 3D format information and recommendation setting information 1410, 1420, and 1430 as shown in FIG. 14.

The recommended 3D setting information may include recommended setting information by age, format, or genre, and the recommended 3D setting information 1420 may include a plurality of recommended setting information 1421 and 1422.

In addition, the recommended 3D setting information 1430 may include recommended setting information of a 3D depth and a convergence point of a corresponding program.

Meanwhile, the stereoscopic sense of the viewer may vary according to age, gender, and size of the image display device.

According to an exemplary embodiment of the present invention, the image display apparatus may reduce the 3D depth value as shown in FIG. 15A or increase the 3D depth value as shown in FIG. Can be.

In addition, the gaze point setting value may be changed as shown in FIG. 16 to vary the stereoscopic sense of the overall image.
