For example, the 3D video signal may be divided into a left eye video signal and a right eye video signal, and the separated left eye video signal and the right eye video signal may be scaled as shown in FIG. 5 and output in a predetermined format shown in FIG. 4. .

The OSD generator 174 may directly perform the above-described scaling process with respect to the OSD output. When the OSD generator 174 directly performs scaling on the OSD, the formatter 175 does not need to perform scaling on the OSD. In this case, the OSD generator 174 not only generates the OSD signal, but also scales the OSD signal according to the depth or slope of the OSD, and further outputs the OSD signal in a suitable format. In this case, the format of the OSD signal output from the OSD generator 174 may be any one of various combination formats of a left eye image signal and a right eye image signal, or a left eye image and a right eye image, as shown in FIG. 4. At this time, the output format is the same as the output format of the formatter 175.

6 is a view showing a state in which the depth of the 3D image or 3D object is variable according to an embodiment of the present invention.

According to an embodiment of the present invention described above, the 3D image is composed of a multiview image, wherein the multiview image may be illustrated as a left eye image and a right eye image. In this case, FIG. 6 illustrates a state in which a position recognized as an image is formed from a user's point of view is changed by a distance between a left eye image and a right eye image. Referring to FIG. 6, a stereoscopic or perspective view of an image felt by a user according to an interval or parallax between a left eye image and a right eye image will be described.

In FIG. 6, a plurality of images or objects having different depths are illustrated. 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 includes a first left eye video signal and a first right eye video signal. 6 illustrates at which position of the display unit 180 the first left eye image based on the first left eye image signal and the first right eye image based on the first right eye image signal are displayed. 6 illustrates a distance between the first left eye image and the first right eye image displayed on the display unit 180. The description of the first object may be applied to the second to fourth objects. Hereinafter, for convenience of description, a left eye image and a right eye image displayed on the display unit 180 for one object, an interval set between the two images, and a serial number of the corresponding object will be described.

The first object 615 includes 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 that the extension occurs at the point where 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 cross each other. 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 may be expressed as a depth. In the present exemplary embodiment, the depth of the 3D object recognized by the user, as located behind the display unit 180, has a negative value (−). Therefore, the depth of the first object 615 has a negative value.

The second object 625 is composed of a second right eye image (indicated by 623 and R2) and a second left eye image (indicated by 621 and L2). According to the present exemplary embodiment, the second right eye image 623 and the second left eye image 621 are displayed at the same position on the display unit 180. The interval between the second right eye image 623 and the second left eye image 621 is zero. The user recognizes that the extension line connecting the left eye 601 and the second left eye image 621 and the extension line connecting the user's right eye 603 and the second right eye image 623 cross each other. Accordingly, the user recognizes the second object 625 as if it 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 that are recognized as being protruded toward the user from the display unit 180. Furthermore, the degree of perspective or stereoscopic perception perceived by the user according to the change of the distance between the left eye image and the right eye image may be described with reference to the examples of the third object 635 and the fourth object 645.

The third object 635 includes a third right eye image 633 (denoted as R3) and a third left eye image 663 and denoted by L3. 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 extension line connecting the left eye 601 and the third left eye image 631 and the point where the extension lines of the right eye 603 and the third right eye image 633 cross each other. Accordingly, the user recognizes the third object 625 as if it is located in front of the display unit 180, that is, near the user. That is, the third object 635 is recognized by the user as if the display unit 180 protrudes toward the user. In the present exemplary embodiment, the depth of the 3D object recognized by the user, as located in front of the display unit 180, has a positive value (+). Thus, the depth of the third object 635 has a positive value.

The fourth object 645 is composed of a fourth right eye image (indicated by R3) and a fourth left eye image (indicated by 641 and L4). 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 extension line connecting the left eye 601 and the fourth left eye image 641 and the extension line of the right eye 603 and the fourth right eye image 643 intersect. Accordingly, the user recognizes that the fourth object 645 is located in front of the display unit 180, that is, closer to the user, and closer to the user than the third object 635. That is, the fourth object 645 is recognized by the user as if the fourth object 645 is located protruding toward the user rather than the display unit 180 and the third object 635. The fourth object 645 has a depth positive value.

The image display apparatus 100 adjusts the positions of the left eye image and the right eye image displayed on the display unit 180 so that an object consisting of the left eye image and the right eye image is recognized or displayed to the user as if the object is located behind the display unit 180. It can be made known to the user as if it were located. In addition, the image display apparatus 100 may adjust the display interval of the left eye image and the right eye image displayed on the display unit 180 to adjust the depth of the object composed of the left eye image and the right eye image.

That is, according to the description with reference to FIG. 6, the depth of the object composed of the left eye image and the 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. It can be seen that it is determined. As described above, the object having a positive value (+) having a depth is an object recognized by the user as if the object is protruded from the display unit 180. In addition, an object having a negative value (−) having a depth is an object recognized by the user as if it is located backward from the display unit 180.

6, the depth of the object, that is, the distance between the point recognized by the user as if the 3D image is located and the display unit 180 vary according to the absolute value of the distance between the left eye image and the right eye image. can do.

7 is a diagram illustrating a state in which a sense of 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 varies depending on the distance between the left eye image 701 and the right eye image 702 displayed on the display unit 180. In the present embodiment, the depth of the display unit 180 is set to zero. The depth of the image to be recognized as if protruding from the display unit 180 is set to have a positive value.

The interval between the left eye image 701 and the right eye image 702 illustrated in FIG. 7A is a. The interval between the left eye image 701 and the right eye image 702 illustrated in FIG. 7B is b. Where b is larger than aa. That is, in the example illustrated in FIG. 7B, the interval between the left eye image 701 and the right eye image 702 is wider than the example illustrated in FIG. 7A.

In this case, as described with reference to FIG. 6, the depth of the 3D image or the 3D object illustrated in FIG. 7B is greater than the depth of the 3D image or the 3D object illustrated in FIG. 7A. . In each case, when the depth is quantified and expressed as a 'and b', respectively, it can be seen that a '<b' relationship is also established according to a <b. In other words, when the 3D image is projected, the depth of the expression may be increased or decreased as the distance between the left eye image 701 and the right eye image 702 is increased or decreased.

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

The image display apparatus 100 may be controlled by a signal transmitted from the remote control apparatus 200. The user may input commands such as power on / off, channel up / down, volume up / down, etc. to the image display apparatus 100 using the remote control apparatus 200. The remote control apparatus 200 transmits a signal including a command corresponding to a user's manipulation to the image display apparatus 100. The image display apparatus 100 may determine a signal received from the remote control apparatus 200 to 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 may transmit a signal to the image display apparatus 100 according to the IR communication standard. In addition, the remote control apparatus 200 may transmit a signal to the image display apparatus 100 or receive a signal transmitted by the image display apparatus 100 according to another type of wireless communication standard. Among the remote control apparatus 200, there may be a remote control apparatus 200 that detects a user's movement and transmits a signal including a command corresponding to the movement to the image display apparatus 100. In this embodiment, such a remote control device 200 will be described as an example of a spatial remote control. According to various embodiments of the present disclosure, in addition to the space remote control, a general wired / wireless mouse or an air mouse or various pointing means or remote controllers in various forms (rings, bracelets, thimbles, etc.) may correspond to the remote control apparatus 200. have.

In the embodiment described with reference to FIGS. 8 and 9, the spatial remote control 201 is one of the remote control apparatus 200 capable of inputting a command to the image display apparatus 100 for remote control of the image display apparatus 100. ) And a perspective view of the spatial remote control 201 is shown in FIGS. 8 and 9.

In the present embodiment, the spatial remote controller 201 may transmit and receive a signal with the image display apparatus 100 according to RF communication standard. As illustrated in FIG. 8, a pointer 202 corresponding to the spatial remote control 201 may be displayed on the image display apparatus 100.

The user may move or rotate the space remote control 201 up, down, left, and right. The pointer 202 displayed on the image display apparatus 100 corresponds to the movement of the spatial remote control 201. FIG. 9 illustrates a bar in which the pointer 202 displayed on the image display apparatus 100 moves in response to the movement of the spatial remote control 201.

In the example described with reference to FIG. 9, when the user moves the spatial remote control 201 to the left side, the pointer 202 displayed on the image display apparatus 100 also moves to the left side correspondingly. In this regard, the spatial remote control 201 may be provided with a sensor that can determine the movement. Information about the movement of the spatial remote controller 201 detected by the sensor of the spatial remote controller 201 is transmitted to the image display apparatus 100. The image display apparatus 100 may calculate the coordinates of the pointer 202 from information about the movement of the spatial remote control 201. The image display apparatus 100 may display the pointer 202 to correspond to the calculated coordinates.

As illustrated in FIGS. 8 and 9, the pointer 202 displayed on the image display apparatus 100 may move in response to the up, down, left, or right rotation of the spatial remote control 201. The moving speed or the moving direction of the pointer 202 may correspond to the moving speed or the moving direction of the spatial remote control 201.

For the above-described series of operations or functions of the space remote control 201, the space remote control 201 is 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, a remote control unit And may include submodules. That is, the remote control unit of the spatial remote controller generates the remote control signal by processing the information or signal detected from the user input unit and / or the sensing unit. For example, the remote control signal includes information about a portion of a keypad or a button corresponding to a user input unit, pressure or touch duration, duration of pressure or touch, and coordinates or angles at which the spatial remote controller is moved or rotated through the sensing unit. Can be generated based on the information about the.

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 unit interface unit 140 of the image display device. In addition, the remote control wireless communication unit may receive a wired / wireless signal transmitted from the image display device.

In particular, the sensing unit may include a gyro sensor or an acceleration sensor. The gyro sensor may sense information about the movement of the spatial remote control 201. For example, the gyro sensor may sense information about the operation of the spatial remote controller 201 based on the x, y, and z axes. The acceleration sensor may sense information about a moving speed of the spatial remote control 201.

The sensing unit senses which part of the progress bar to be described later by using the provided sensors, and transmits information necessary for generating a remote control signal such as detected position information or coordinate information to the remote control unit. Accordingly, when the remote control signal or the edit start signal and / or the edit end signal to be described later are generated by the remote control unit, the remote control wireless communication unit may output the corresponding signal to the remote control unit interface unit 140.

The remote control information storage unit stores various types of programs and application data necessary for controlling or operating an image display device or a spatial remote controller. For example, when the wireless communication between the image display device and the spatial remote control is performed, the remote control information storage unit stores the used frequency band, so that the remote control information regarding the frequency band can be used for communication of the wall.

In addition, the power supply unit is a module for supplying power required for driving the spatial remote control. According to an example, when the power supply unit outputs a signal for commanding that the remote control unit temporarily stops or resumes the power supply according to the movement of the spatial remote controller detected by the sensing unit, the power supply unit supplies power according to the control signal. By varying t, power can be saved while the spatial remote control is not used or not in operation.

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

10 is a flowchart illustrating a method of operating an image display apparatus according to an exemplary embodiment.

The image is reproduced under the control of the controller 170 (S510). The video signal may be received from the broadcast signal receiver 110, the network interface unit 120, or the external device input / output unit 130. The display unit 180 displays a video to be played and a progress bar according to the playback of the video (S520). The progress bar may be generated by the user interface controller or the controller 170 described above. In addition to the image being played and the progress bar, thumbnail images of the image being played may be displayed together.

Thereafter, the remote control interface 140 receives the edit start signal (S530). The edit start signal is a user signal for setting an edit target section in the playback video, and is a signal for determining from which part of the video being played back to edit. The edit start signal may be input from the remote controller 200. Here, the remote control device 200 to be illustrated as a space remote control. When the spatial remote controller points to a specific point in the progress bar, an edit start signal is input for a time point corresponding to the corresponding position. Then, the part after the edit start signal is input is set as the edit target section.

In addition, a thumbnail image may be displayed. In particular, a thumbnail image of an image reproduced at a time point at which an edit start signal is input and / or before and after the display is particularly displayed in three dimensions. Then, after the edit start signal is input, the progress bar for the portion set as the edit target section is also displayed in three dimensions (S540). Here, the progress bar for the thumbnail image or the section to be edited is displayed in three-dimensionally. The progress bar, which is displayed in solid or planar shapes, is displayed in the shape of a three-dimensional figure, and the thumbnail image or progress bar, which is displayed in a two-dimensional image, is three-dimensional. It includes what is displayed as an image. Signal processing of the display image in a three-dimensional image or in three dimensions has been described with reference to FIG. 2 and will be omitted.

In this case, since the progress bar for the editing target section is three-dimensionally displayed, the progress bar for the editing target section or the progress bar for the part after the edit start signal is input may be displayed separately from the progress bar for the other sections. And may appear to appear disconnected. For example, the controller 170 displays the progress bar of the portion corresponding to the time point after the edit start signal is input in a three-dimensional figure, and the progress bar of the corresponding portion before the edit start signal is input in a flat figure. can do. The progress bar of the portion corresponding to the time after the edit start signal is input and the progress bar of the corresponding portion before the edit start signal is input may be displayed to be discontinuous without being in contact with each other. This is not only to visually distinguish the part after the edit start signal is input, but also to visually express the fact that the edit start signal is input. There may be a variety of methods, such as changing the color, the texture of the progress bar, or the thickness, such that the part after the edit start signal is input and the part before the edit start are visually distinguished.

At this time, all the images before the edit start signal is input as 2D images for the three-dimensional display of the progress bar, and after the edit start signal is input, the image is switched to 3D mode, or only the portion of the progress bar or the thumbnail image is 3D. Images other than those displayed may be maintained as 2D images.

In any of the above two cases, a multi-view video is displayed for the progress bar corresponding to the part after the edit start signal is input. Then, after viewing the multi-view image of the progress bar after the edit start signal is input, the user can recognize that the 3D effect is applied. Therefore, it is obvious that the progress bar corresponding to the part before the edit start signal is input and the progress bar of the subsequent part are displayed disconnected or distinguished.

To this end, the controller 170 generates a multi-view image of the progress bar of the edit start time and the part after the edit start. Here, the multi-view image may mean, for example, a left eye image and a right eye image. If the entire image has already been displayed as the left eye image and the right eye image, by adjusting the interval or parallax of the multiple view image with respect to the progress bar of the edit start time and the part after the edit start, the progress bar of the corresponding portion is more than the progress bar of the remaining portions. Try different depths. The display unit displays the multi-view image of the progress bar in which the interval between the multi-view images and the depth of the image are adjusted accordingly.

Generating the multi-view image or increasing or decreasing the depth by changing the interval of the multi-view image may be similarly applied to the thumbnail image corresponding to the point of time at which the edit start signal is input and after. When the edit start signal is input, a thumbnail image at the edit start time is extracted, and a multi-view image is generated for the thumbnail image. If a thumbnail image at the start of editing has already been extracted and a multi-view image thereof has already been generated, the image may be processed so that the thumbnail image may have a greater depth by using an interval between the multi-view images. That is, the controller 170 adjusts the interval between the left eye image and the right eye image for the thumbnail image at the start of editing and the thumbnail image thereafter. As a result, the controller 170 may display the thumbnail images indicating the editing start point and the thumbnail images of the parts included in the later editing target section in three-dimensional contrast with the thumbnail images before the editing start point.

If the progress bar at the start of editing and after is composed of the left eye image and the right eye image, and has a positive sense of depth, that is, protruding in the direction in which the user is present, the distance between the left eye image and the right eye image is different. It can be wider than 3D video.

The display state of the progress bar may be controlled by the controller 170 or the above-described user interface controller. The user can easily grasp the editing target section set by the progress bar and the thumbnail images displayed as the multi-view images.

11 is a flowchart illustrating a method of operating an image display apparatus according to another exemplary embodiment.

The display unit 180 displays an image to be played and a progress bar (S610). In order to edit the image, the remote control interface unit receives an edit start signal by a user's command input (S620). The setting of the edit target section is started by input of the edit start signal.

In operation S630, it is determined whether a thumbnail image exists by searching for a thumbnail image of an image reproduced at the time when the edit start signal is input or an image reproduced before and after including the time. When a thumbnail image of a scene corresponding to a point in time at which an edit start signal is input is generated, a user can more easily determine from which part the edit is started.

As a result of the search, when the thumbnail image corresponding to the image reproduced at the time when the edit start signal is input, the display unit 180 displays the corresponding thumbnail image (S640). . If there is no thumbnail image corresponding to the image played back when the edit start signal is input, as a result of the search, the thumbnail image of the image of the corresponding portion is extracted or generated to display the thumbnail image (S635 and S640).

In addition, the remote control interface 140 receives the edit end signal (S650). The edit end signal is a signal that designates the end point of the edit target section. The editing start signal can be input in the same manner. That is, by using a remote control device such as a space remote controller, the user may input an edit end signal by pointing a specific point of the progress bar. Obviously, the point pointed for input of the edit end signal on the progress bar should be located behind the point pointed for input of the edit start signal.

When the edit end signal is input, the apparatus searches for whether a thumbnail image for a video to be reproduced is present at or near the edit end time (S660). If there is no thumbnail image for the end of the search result editing, a required thumbnail image is extracted or generated (S665). When the thumbnail image exists or the thumbnail image is extracted or generated as a result of the search, the display unit 180 displays the thumbnail image (S670). When both the video corresponding to the editing start point and the thumbnail video for the video corresponding to the end point of editing are displayed, the user can easily determine from which part of the entire video to which part the video is set as the editing target section at the time of editing. In addition, it can be easily reminded of which part is edited when the editing target section is needed.

As a result, when both the editing start signal and the editing end signal are input and both the editing target sections are set, the controller 170 or the user interface controller processes the progress bar corresponding to the editing target section to be displayed in three dimensions (S680). If the edit end signal is not input, the edit target section may be automatically set from the time point at which the edit start signal is input to the time point at which playback of the video ends.

In order to display the progress bar for the editing target section in three dimensions, the controller 170 may generate a multi-view image of the progress bar of the corresponding portion or vary the interval between the multi-view images. As described above, the multi-view image may be exemplified as a left eye image and a right eye image. The thumbnail image corresponding to the editing target section may also be displayed in three dimensions, and a multi-view image of the thumbnail image may also be generated and displayed. As a result, the progress bar and the thumbnail images of the editing target section are recognized by the user as a 3D object. In addition, the image, the progress bar, and the thumbnail image irrelevant to the editing target section are visually distinguished by having a different sense of depth even if they are displayed flat or three-dimensionally regardless of the multi-view image.

The method of creating visual differentiation from other parts by adjusting the three-dimensional or depth of the progress bar or the thumbnail image by generating the multi-view image or adjusting the spacing between the multi-view images may be commonly applied in an embodiment of the present invention.

The video included in the editing target section may be stored in the storage 160 separately from the existing playback video (S690). Although the editing has been described as an example of storing, the concept of editing includes not only storing but also deleting and modifying, so that an image of a part set as a playback target section may be deleted or modified according to a user's input signal.

12 and 13 illustrate progress bars and thumbnail images displayed according to an embodiment of the present invention.

12 is a diagram illustrating a progress bar and a thumbnail image after receiving an edit start signal and receiving an edit end signal, and FIG. 13 illustrates a process after receiving an edit start signal and an edit end signal and determining an edit target section. A bar and thumbnail image is shown.

The pointer 720 by a remote control device such as a spatial remote controller points to the first point 710 so that the setting of the editing target section starts, and the playback target section starts from the portion corresponding to the first point 710. . When the setting of the editing target section is started according to the input of the editing start signal, the progress bar 730 for the portion after the first point 710 and the first point 710 is three-dimensionally displayed. That is, the progress bar 730 for the part after the point in time at which the edit start signal is input is displayed in three dimensions unlike the previous part, so that the progress bar for the part before the edit start signal is input is visually distinguished from the progress bar for the part before the edit start signal is input. do.

The edit start thumbnail image 740 for the video corresponding to the point in time at which the edit start signal is input, that is, the edit start point, is extracted and displayed. If the extracted thumbnail image for the editing start time already exists, a separate thumbnail extraction process for the editing start thumbnail image 740 may be omitted. This allows the user to visually check which scene corresponds to the editing target section at the time of editing and afterwards.

Until the editing of the image or the reproduction of the image is finished, the stereoscopic effect on the progress bar 730 for the part after the edit start time is maintained. Thumbnail extraction and thumbnail display may also be maintained until the end of editing.

Afterwards, referring to FIG. 13, an editing end signal is input. In the embodiment described with reference to FIG. 8, an editing target section is determined by input of an editing end signal. As the spatial remote controller points the second point 810 with the pointer 720, an edit end signal corresponding to the point of time indicated by the second point 810 is input. The section from the first point 710 to the second point 810 is determined as the editing target section. In addition, the progress bar 830 from the first point 710 to the second point 810 is displayed in three dimensions, and the progress bar for other parts is displayed as if disconnected or visually distinguishable. Accordingly, the progress bar for the portion after the second point 810 is released in three-dimensional display, and is displayed to be distinguished or disconnected from the progress bar 830 for the editing target section.

In this case, the progress bar 830 for the editing target section is displayed to be disconnected or distinguished from other parts, corresponding to the point in time until the control unit 170 receives the edit end signal after the edit start signal is input. The progress bar of the portion may be displayed in a three-dimensional figure, and the progress bar corresponding to the portion before the edit start signal is input or after the edit end signal is input may be displayed in a flat figure.

For the stereoscopic display of the progress bar for the editing target section, the progress bar for the editing target section of the three-dimensionally expressed portion may be composed of a multi-view image. If the part except the progress bar for the editing target section is already displayed as a 3D image using the multiview image, the distance between the left eye image and the right eye image of the multiview video for the progress bar for the editing target section is adjusted. You can put a difference in depth between the image of the part.

In addition, the progress bar 830 of the part included in the editing target section and the progress bar of the remaining part may be displayed to be discontinuous without being in contact with each other. Accordingly, not only the progress bar 830 corresponding to the editing target section is visually highlighted, but also the fact that the edit start signal and the edit end signal are input can be visually represented. In order to visually distinguish the progress bar 830 of the editing target section and the progress bar of the other part, in addition to whether or not to apply a stereoscopic effect, the color of the progress bar or the thickness, width, and texture of the progress bar may be changed. There may be a variety of ways.

The progress bar 830 for the section to be edited and the progress bar for other portions are displayed to be visually distinguished by the color or texture effect of the progress bar.

The edit end signal is input, and the edit end thumbnail image 840, which is a thumbnail image of the video corresponding to the point in time at which the edit end signal is input, is also extracted and displayed. If a thumbnail image of the scene at the end of editing has already been extracted, a separate generation process for the editing end thumbnail image 840 may be omitted.

In the display of the thumbnail image for the editing target section, the thumbnail images for the images included in the editing target section are not only displayed in three dimensions but also stored together with the editing target section. Therefore, the thumbnail image may be generated for the images before and after the editing target section, but the thumbnail images of the editing target section may be visually distinguished according to whether the stereoscopic effect is applied, the image quality of the thumbnail image, or the color. When the editing target section is checked at the time of editing or after editing, the user can easily grasp which section is edited using the thumbnail images.
