4 is a flowchart illustrating a method of operating an image display device according to an exemplary embodiment of the present invention, and FIGS. 5 to 8 are views referred to for explaining the method of FIG. 4.

Referring to the drawings, first, an image is displayed on the first display 180 (S410). In this case, the image may be a broadcast signal image or an external input image from an external input device. Also, it may be a playback image of multimedia data stored in the first storage unit 175 or the second storage unit 175.

5 (a) and 6 (a) show that the broadcast signal image is displayed on the first display 180, respectively.

Next, a thumbnail image corresponding to the image is generated (S410). In operation S415, the generated thumbnail image is displayed on the second display.

The thumbnail image may correspond to the image of the first display 180.

For example, when there is a display input of a thumbnail image from the remote controller 200, the second controller 163 captures an image displayed on the first display 180 and generates a thumbnail image corresponding thereto. Can be.

In FIG. 5B, the pointer 302 of the spatial remote controller is used. That is, when the image 510 displayed on the first display 180 is dragged onto the second display 183, the generated thumbnail image 535 is added and displayed as shown in FIG. 5C. Accordingly, the thumbnail list 520 is updated with the thumbnail list 530 including the newly added thumbnail image 535 and displayed on the second display 183. In this way, by stacking the thumbnail image on the second display 183, it is also possible to simply edit it for future user convenience.

For example, the second controller 163 may generate a thumbnail image by capturing a portion of the stored image while the image displayed on the first display 180 is being stored. As the storage time of the image displayed on the first display 180 becomes longer, the number of thumbnail images generated may increase. As such, by stacking the thumbnail image on the second display 183, the stored image may be easily confirmed. In addition, it is also possible to easily edit for future user convenience.

For example, when the broadcast channel of the image displayed on the first display 180 is converted, the second controller 163 may generate a thumbnail image corresponding to the broadcast signal image before or after the conversion. .

In FIG. 6, when the broadcast channel is changed from "CH13" to "CH25", the thumbnail image 635 is generated and displayed corresponding to the broadcast channel image 610 before the change. Accordingly, the thumbnail list 620 is updated with the thumbnail list 630 including the newly added thumbnail image 635 to be displayed on the second display 183. Meanwhile, unlike the drawing, it is also possible to generate and display a thumbnail image corresponding to the changed broadcast channel image 620.

As described above, the thumbnail image may be generated by the channel browsing processor (not shown) or the first controller 160 in addition to the second controller 163.

Meanwhile, the thumbnail image may be a still image or a moving image. In addition, the thumbnail image may be an image in which the resolution, that is, the size, of the image displayed on the first display 180 is reduced.

Next, it is determined whether there is a merge input of the selected thumbnail image among the plurality of thumbnail images (S420), and when there is a merge input, a merged thumbnail image is generated (S425). The generated thumbnail image is displayed on the second display (S430).

For example, as illustrated in FIG. 7, when the first thumbnail image 723 and the second thumbnail image 726 are selected from among a plurality of thumbnail images displayed on the second display using a pointer of the spatial remote controller 301. The second control unit 163 may determine this as a merge input to generate a new merge thumbnail image 735 by merging the first thumbnail image 723 and the second thumbnail image 726. Accordingly, the thumbnail list 720 is updated to the thumbnail list 730 including the newly added thumbnail image 735 to be displayed on the second display 183.

Meanwhile, unlike the drawing, it is possible to generate the merged thumbnail image 735 by dragging the first thumbnail image 723 to the second thumbnail image 726 or vice versa.

In addition, at least two thumbnail images may be selected and merged using the direction key and the selection key of the remote controller 200 instead of the spatial remote controller 301.

Next, it is determined whether the merged thumbnail image is selected (S435), and when there is a selection input of the merged thumbnail image, an image corresponding to the merged thumbnail image is displayed on the first display 180 (S440).

For example, as shown in FIG. 8, when the merged thumbnail image 815 is selected from the thumbnail list 820 displayed on the second display 183, the image corresponding to the merged thumbnail image is displayed in the first display 180. ). In FIG. 8B, an image 830 corresponding to one of the thumbnail images 815 in which two thumbnail images are merged is displayed on the first display. In FIG. 8C, FIG. The image 840 corresponding to the other thumbnail image of the merged merge thumbnail image 815 is displayed on the first display.

Unlike the drawing, it is also possible to display an image corresponding to the merged thumbnail image together on the first display 180 in the form of a picture in picture (PIP). Accordingly, the user can watch the images corresponding to the merged thumbnail images continuously or together.

Although not shown in the figure, it is also possible to edit the thumbnail image displayed on the second display 183. For example, one thumbnail image of a plurality of thumbnail images may be selected, stored, deleted, locked, or unlocked. Meanwhile, when a plurality of thumbnail images is displayed on the second display 183, it is also possible to perform the alignment of the thumbnail images. For example, it is possible to arrange the thumbnail image according to the generation time, preference, type of thumbnail image, and the like. Accordingly, user convenience may be increased.

FIG. 9 is a flowchart illustrating a method of operating an image display device according to an exemplary embodiment of the present invention, and FIG. 10 is a diagram referred to describe the method of operation of FIG. 9.

Referring to the drawings, first, a content list is displayed on the first display 180 (S910). In this case, the content list may be a content list stored in the image display apparatus 100, for example, in the storage units 175 and 178, or a content list in an external device connected to the image display apparatus 100.

The content list may be any one of an image file list, a video file list, a music file list, a text file list, and the like.

FIG. 10A shows that the image file list 1010 is displayed on the first display 180.

Next, a thumbnail image corresponding to the selected content of the content list is generated (S910). The generated thumbnail image is displayed on the second display (S915). The thumbnail image may correspond to the image of the first display 180.

For example, the second controller 163 may generate a thumbnail image corresponding to the selected content.

In FIG. 10B, when the first content item 1043 is selected from the content list 1010 using the pointer 302 of the spatial remote controller, a first thumbnail corresponding to the first content item 1043 is illustrated. An image 1023 is generated and shown on the second display 183. By selecting any one item from the image file list, the user can pre-view and thus easily grasp the contents of the file.

Meanwhile, in FIG. 10C, when the second content item 1046 is selected from the content list 1010 by using the pointer 302 of the spatial remote controller, the second content item 1046 corresponds to the second content item 1046. It shows that two thumbnail images 1026 are generated and displayed on the second display 183. In this way, by stacking the thumbnail image on the second display 183, it is also possible to simply edit it for future user convenience.

Meanwhile, the image file list or the video file list as shown in FIG. 10 may generate a thumbnail image through capture from the corresponding file. On the other hand, thumbnail images for other music file lists, text file lists, and the like can be newly generated as thumbnail images indicating corresponding items.

Next, steps 920 to 940 (S920 to S940) are the same as steps 420 to 440 (S420 to S440) of FIG. 4.

However, when the content list is a music file list, in operation S940, the merge file may be played instead of displaying the image corresponding to the merged thumbnail image on the first display.
