In addition, this can serve as a factor for diversifying and maximizing the stereoscopic effect of the image sensed by the user.

The slope effect or the rotation effect applied to the image according to the shape of the image is determined by the difference in length of the parallel sides of the trapezoid shape 516 illustrated in Figure 5 (b) By adding or subtracting the diagonal size difference of the parallelogram 519 illustrated in Fig.

In this case, even within a single 3D image or a 3D object, different tilting intervals may be applied to each part, resulting in a tilting effect. In other words, in order to make the image appear to be tilted or rotated, a part having a larger depth and a part having a smaller depth coexist in a 3D image or a 3D object. This means that a parallax interval for a pair of left- As shown in FIG.

When one of the left eye image and the right eye image for displaying the 3D image or the 3D object is generated in the shape shown in FIG. 5 in the scaler or the OSD generating unit in the controller 170, the generated left eye or right eye image is copied And a pair of binocular images can be generated by generating one remaining image.

On the other hand, the scale adjustment of the 3D image signal or the 3D object may be performed by the formatter 175 of the control unit 170 described above. The 3D image signal and the like in FIG. 5 may be a signal obtained by combining a left eye image signal, a right eye image signal, or a left eye image signal and a right eye image signal.

The formatter 175 receives the decoded video signal, separates the 2D video signal or the 3D video signal, and separates the 3D video signal into the left eye video signal and the right eye video signal. 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 generation unit 174 may directly perform the image signal generation process or the scaling process described above with respect to the OSD 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 showing a variation in depth of a 3D image or a 3D object according to an 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.

FIG. 7 is a view illustrating a manner 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.

8 and 9 are views illustrating an image display apparatus and a remote control apparatus according to an embodiment of the present invention.

The image display apparatus 100 can be controlled by a signal transmitted from the remote control apparatus 200. [ The user can input commands such as power on / off, channel up / down, volume up / down, etc. to the video display device 100 using the remote control device 200. The remote control apparatus 200 transmits a signal including a command corresponding to the operation of the user to the image display apparatus 100. [ The image display apparatus 100 can discriminate a signal received from the remote control device 200 and generate a control signal according to the signal or perform an operation according to a command included in the signal.

The remote control apparatus 200 can transmit a signal to the image display apparatus 100 according to the IR communication standard. Also, the remote control device 200 may transmit a signal to the image display device 100 or a signal transmitted from the image display device 100 according to another type of wireless communication standard. There may be a remote control device 200 that can detect a movement of a user of the remote control device 200 and transmit a signal including a command corresponding to the motion to the image display device 100. [ In the present embodiment, this remote control device 200 will be described as an example using a space remote controller. According to various embodiments of the present invention, in addition to a space remote controller, a general wired / wireless mouse, an air mouse, various pointing means, and remote controllers of various forms (rings, bracelets, thimble, have.

8 and 9, one of the remote control devices 200 that can input commands to the video display device 100 for remote control of the video display device 100 is a spatial remote controller 201 And FIGS. 8 and 9 are perspective views of the space remote controller 201. As shown in FIG.

In this embodiment, the spatial remote controller 201 can transmit and receive signals in accordance with the RF communication standard with the image display apparatus 100. As shown in FIG. 8, a pointer 202 corresponding to the spatial remote controller 201 may be displayed on the image display device 100.

The user can move or rotate the space remote controller 201 up, down, left, right, back and forth. The pointer 202 displayed on the video display device 100 corresponds to the motion of the spatial remote controller 201. [ FIG. 9 shows a bar 202 displayed on the image display device 100 in response to movement of the spatial remote controller 201.

In the example described with reference to FIG. 9, when the user moves the spatial remote controller 201 to the left, the pointer 202 displayed on the video display device 100 also moves to the left corresponding thereto. In this regard, the spatial remote controller 201 may be provided with a sensor capable of detecting movement. Information on the motion of the spatial remote controller 201 sensed through the sensor of the spatial remote controller 201 is transmitted to the image display apparatus 100. The image display apparatus 100 can calculate the coordinates of the pointer 202 from the information on the motion of the spatial remote controller 201. [ The image display apparatus 100 can display the pointer 202 so as to correspond to the calculated coordinates.

As shown in FIGS. 8 and 9, the pointer 202 displayed on the image display apparatus 100 can be moved corresponding to the up, down, left, right, or rotation of the spatial remote controller 201. The moving speed and the moving direction of the pointer 202 may correspond to the moving speed and the moving direction of the spatial remote controller 201.

For the aforementioned series of operations or functions of the spatial remote controller 201, the spatial remote controller 201 includes a remote control wireless communication unit, a user input unit, a sensor unit, a remote control signal output unit, a power supply unit, a remote control information storage unit, And the like. That is, the remote controller of the spatial remote controller processes information or signals sensed by the user input unit and / or the sensing unit to generate a remote control signal. The remote control signal includes, for example, information as to which part of the keypad or button corresponding to the user input unit is applied with pressure or touch, a time at which the pressure or touch has been sustained, and coordinates or angles in which the spatial remote controller moved or rotated through the sensing unit Can be generated based on the information about the user.

The remote control signal generated through the above process is transmitted to the image display device through the remote control wireless communication unit. More specifically, the remote control signal output through the remote control wireless communication unit is input to the remote control device interface unit 140 of the video display device. The remote control wireless communication unit may receive the wire / wireless signal transmitted by the video display device.

The remote control information storage unit stores various kinds of programs and application data necessary for controlling or operating the image display apparatus or the spatial remote controller. For example, when wireless communication is performed between the video display device and the spatial remote controller, the remote control information storage section stores the used frequency band, and remote control information related to the frequency band can be used in the communication of the remote control information storage section.

In addition, the power supply unit is a module that supplies power and the like necessary for driving the spatial remote controller. According to one example, when the remote control unit temporarily stops the power supply or outputs a signal instructing to restart the power supply depending on whether the spatial remote controller sensed by the sensing unit is moving, The power can be saved while the spatial remote controller is not used or is not operating.

As another example, a predetermined command may be set to be input to the image display apparatus 100 in response to the movement of the spatial remote controller 201. That is, even if a certain pressure or touch is not detected in the user input unit, a predetermined command can be inputted or generated only by the motion of the spatial remote controller. For example, when moving the remote control 201 back and forth, the size of the image displayed on the image display device 100 may be enlarged or reduced. Thus, examples of spatial remote controls do not limit the scope of the present invention.

10 is a flowchart illustrating an operation method of an image display apparatus according to an embodiment of the present invention. According to the embodiment described with reference to FIG. 10, at the same time as viewing the main image, the user views the sub images displayed together and selects one of the ARC (Aspect Ratio Control) modes to set or change the ARC mode of the main image .

First, the control unit 170 reproduces the main image (S1010). The main image is a video image received from a broadcasting station, a video image input from an external input device (USB, DVD player, etc.), a video image received from a network such as an IP network, Of the total number of images.

The controller 170 generates a sub-image and outputs the image signals for the main image and the sub-image to the display unit. The user is provided with a user interface for selecting the ARC mode through the sub video. Before receiving the ARC mode selection signal, the display unit 180 displays sub-images for each ARC mode (S1020).

In the embodiment of the present invention, the sub-image means a preview image indicating the ARC mode. When the ARC mode is applied to the main image, the image is displayed in advance to show how the main image is to be displayed. In most cases, the size of the main image is smaller than that of the main image. The sub-image may be a still image or a moving image, and may have a form of a thumbnail image.

The Aspect Ratio Control (ARC) mode can include aspects such as 4: 3, 16: 9 aspect ratio, how to set the aspect ratio, and how to set the size of the screen. In addition, there is a zoom-in mode in which some or all of the image being played back is zoomed in as if it is seen at a close distance, a zoom-in mode in which some or all of the image being played is zoomed out as seen from a long distance -out) mode may also be one of the ARC modes.

In addition, the ARC mode may be related to the curvature of the image. Examples include convex lens mode and concave lens mode. When the ARC mode of the main image is set to the convex lens mode, the main image is enlarged and displayed in the center portion of the image as seen through the convex lens. When the ARC mode of the main image is set to the concave lens mode, the center portion of the image is reduced and the edge portion is enlarged as shown through the concave lens. That is, when the user selects the convex lens mode in the ARC mode selection process, the main image to which the convex lens effect is applied is displayed. When the concave lens mode is selected, the main image to which the concave lens effect is applied is displayed. When the convex lens mode or the concave lens mode is applied to the main image, a spectacular and dynamic effect can be added to the image, and the user can receive various impressions from the same contents.

Here, the sub-image representing each ARC mode is displayed as a stereoscopic image. That is, since the sub-image is composed of the plurality of view-point images, it can have a different depth sense from the main image. If only the sub-image is composed of a plurality of view-point images, the depth value of the main image may be 0 and the depth value of the sub-image may have a value other than 0. Of course, even when the main image and the sub-image are both composed of a plurality of view-point images, the depth values of both of them can be set differently.

Here, the multiple view image can be exemplified as a left eye image and a right eye image. That is, the depth of the corresponding image changes depending on the interval between the left eye image and the right eye image. For example, in the case of a sub-image having a depth value larger than 0, that is, displayed as being protruded from the display unit 180, the greater the interval between the left-eye image and the right- On the contrary, as the interval between the left eye image and the right eye image is set narrower, the depth feeling of the corresponding sub image is decreased.

When a plurality of sub images are displayed in three dimensions, at least one of the sub images may be activated. The activation of the sub-image may be a step before the ARC mode selection signal to be described later is inputted. When the sub video is activated, it means that the corresponding sub video is selected or the ARC mode selection signal for the corresponding item can be inputted immediately. For example, when a user places a cursor or a pointer on a specific sub-image among a plurality of sub-images, or when a cursor or a pointer stays at a position corresponding to the sub-image for a predetermined time or more in a state where the sub- The image is activated.

The activated sub-image may have a different depth sense from other sub-images and / or main images that are not activated. That is, if it is determined that the specific sub-image is activated, the control unit 170 increases or decreases the interval between the left-eye image and the right-eye image that constitute the sub-image. If the interval between the left eye image and the right eye image of the activated sub image is increased when the sub images are displayed as protruded, the activated sub image is displayed larger than the other sub images having a depth sense. That is, the degree of the protrusion of the activated sub-image is larger than that of the other sub-images.

As described above, the depth of the sub images is set larger than that of the main image. That is, the sub images may be displayed so as to protrude from the main image. In this case, the sub-image can be displayed transparently. The higher the transparency is, the blurred sub-picture is displayed, but the viewing of the main picture may not be disturbed.

The user inputs the ARC mode selection signal through the sub images. The remote control device 200 can be used for inputting the ARC mode selection signal. Here, the remote control device 200 may be exemplified by the above-described space remote controller (see 201 in FIG. 8). In this case, the user input unit receives the ARC mode selection signal from the remote control device 200 (S1030).

The case where the user inputs the ARC mode selection signal using the spatial remote controller will be described as an example. The user can select one sub-image among a plurality of sub-images displayed on the display unit 180, position a cursor or a pointer of the spatial remote control on the sub-image, and input an ARC mode selection signal. Then, the remote control device interface unit 140 receives the ARC mode selection signal and transmits the ARC mode selection signal to the controller 170.

Then, the controller 170 applies the selected ARC mode to the main image, and outputs the image signal of the main image to which the ARC mode is applied, to the display unit 180. Accordingly, the display unit 180 displays the main image according to the selected ARC mode (S1040).

The control unit 170 may enlarge and display the sub-image according to the ARC mode close to the main image before applying the ARC mode according to the ARC mode selection signal to the main image. Such an operation may be added to inform the user more accurately about the state of the screen when the ARC mode is applied to the actual main image. In this case, the scaler of the controller 170 enlarges the size of the selected sub-image, and the video signal is output to the display unit 180. [ After the enlarged sub-image is displayed, if the user inputs a user signal to apply the ARC mode as it is, the ARC mode is actually applied to the main image, and the main image of the subsequent portion can be reproduced according to the ARC mode .

11 is a diagram illustrating an example of a scaler of an image display apparatus according to an embodiment of the present invention.

As described above, the control unit 170 reproduces a main image and generates a sub image. You can change the display state of the main image by applying various ARC modes to the main image.

When a plurality of ARC modes are supported, the controller 170 can generate a plurality of sub images according to the type of each ARC mode. In particular, the size of the screen, the ratio of the screen length to the screen length, 170 may be performed by the scaler 173b. For this, the controller 170 may include two or more scalers 173b. In the embodiment of the present invention, the case where the scaler 173b includes the main scaler 1110 and the sub-scaler 1120 will be described as an example.

The main scaler 1110 controls the scale of the main image, and the sub-scaler 1120 scales the sub-images according to the respective ARC modes. 11, the subscaler 1120 includes a first OSD processing unit 1121, a second OSD processing unit 1123, and a third OSD processing unit 1125. The first OSD processing unit 1121, the second OSD processing unit 1123, and the third OSD processing unit 1125 process video signals of sub images according to three different ARC modes. The three ARC modes are referred to herein as a first ARC mode, a second ARC mode, and a third ARC mode. The first sub-image is regarded as a kind of OSD image.

While the main scaler 1110 performs scale adjustment on the main image, the subscaler 1120 scales the sub-image according to the first ARC mode, the sub-image according to the second ARC mode, and the sub- Perform scale adjustment in turn. The first OSD processing unit 1121, the second OSD processing unit 1123 and the third OSD processing unit 1125 copy or receive the image signals for the respective sub-images scaled from the sub-scaler 1120, 180). At this time, the controller 170 may combine the video signal of the main video and the video signal of the sub video to output the main video and the sub video to the display unit 180 in order to display the main video and the sub video together.

12 and 13 are views showing a main image and a sub image displayed by the image display apparatus or the operation method thereof according to the embodiment of the present invention.

Referring to FIGS. 12 and 13, a main image 1210 and sub images (a first sub image 1221, a second sub image 1223, and a third sub image 1225) are displayed together.

The first sub-image 1221, the second sub-image 1223, and the third sub-image 1225 are preview images generated according to different ARC modes. That is, the first sub-image 1221 is a sub-image for previewing the display method when the first ARC mode is applied to the main image. When the first ARC mode is applied, the aspect ratio of the main image is set to 4: 3. Scaling of the first sub-image 1221 may be performed by the first OSD processing unit 1121. The second sub-image 1223 is a sub-image for previewing the display method when the second ARC mode is applied to the main image. When the second ARC mode is applied, the aspect ratio of the main image is set to 16: 9. Scaling of the second sub-image 1223 may be performed by the second OSD processing unit 1123. Similarly, the third sub-image 1225 is a sub-image for previewing the display method when the third ARC mode is applied to the main image. The third ARC mode represents a zoom-in mode. Therefore, when the third ARC mode is applied, a part of the main image is enlarged and displayed. Scaling of the third sub-image 1225 may be performed by the third OSD processing unit 1125.

The first sub-image 1221, the second sub-image 1223, and the third sub-image 1225 may have a larger depth value than the main image, and may be composed of a plurality of view-point images. That is, by setting the parallax interval between the left eye image and the right eye image, each sub image has a sense of depth as compared with the main image. For example, the sub-images may be displayed as protruding from the main image. In this case, transparency may be applied to the sub-image. Transparency is of course possible. When the sub-image has transparency, the display of the sub-image may prevent the user from being disturbed by the viewing of the main image.

Referring to FIG. 13, a main image 1310 to which a second ARC mode is applied by an ARC mode selection signal is shown. Due to the change to the second ARC mode, the main image 1310 is displayed in a 16: 9 aspect ratio.

The image display apparatus and the operation method thereof according to the present invention are not limited to the configuration and method of the embodiments described above but the embodiments can be applied to all or some of the embodiments May be selectively combined.

Meanwhile, the operation method of the image display apparatus of the present invention can be implemented as a code that can be read by a processor on a recording medium readable by a processor included in the image display apparatus. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium readable by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and also a carrier wave such as transmission over the Internet. In addition, the processor readable recording medium may be distributed over networked computer systems so that code readable by the processor in a distributed manner can be stored and executed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
