[ The pointer generated by the OSD generating unit 174 may be separated into a plurality of view-point images in the formatter 175 so that the pointers can be stereoscopically recognized by the user.

The user can manipulate the OK button provided on the remote controller 200 after adjusting the remote controller 200 so that the pointer is positioned on a predetermined 3D thumbnail. When the controller 170 determines that an OK button or the like provided on the remote controller 200 has been operated, the controller 170 can determine that the 3D thumbnail selection command in which the pointer is located is input. In addition, the user can input a thumbnail selection command to the image display apparatus 100 using various kinds of image display apparatus 100 control means.

The control unit 170 may process the video signal output to the display unit 180 so that the 3D thumbnail corresponding to the input selection command is enlarged (S150). The display unit 180 may enlarge and display an image constituting the 3D thumbnail to which the selection command is input. The control unit 170 may process the video signal output to the display unit 180 so that the selected 3D thumbnail is rotated before enlarging the 3D thumbnail corresponding to the input selection command. That is, when the 3D thumbnail is displayed so as to be tilted, the controller 170 may rotate the 3D thumbnail such that the viewing angle of the selected 3D thumbnail faces the front. Accordingly, the user can confirm the 3D thumbnail corresponding to the input selection command.

The thumbnail generating unit 173 can extract the image of the reproduction time point corresponding to the selected 3D thumbnail from the storage unit 150 (S160). Generally, the resolution of an image constituting a 3D thumbnail is lower than that of a full-screen image. Accordingly, when the image forming the 3D thumbnail is enlarged and displayed on the display unit 180, the user views the image having a low resolution.

In this embodiment, an image constituting a 3D thumbnail is magnified and displayed on the display unit 180, and the same image having a high resolution can be extracted, and then the enlarged image can be replaced with a high-resolution image. In addition, the moving image can be played back from the playback point corresponding to the selected 3D thumbnail (S170). Therefore, the user can view the moving picture from the playback point corresponding to the selected 3D thumbnail.

5 is a flowchart showing a flow of a method of bookmarking 3D thumbnails displayed in the image display apparatus 100 according to an embodiment of the present invention.

The user can select a predetermined 3D thumbnail among the 3D thumbnails displayed on the display unit 180 and input a bookmark command. The bookmark command may be a command for changing the display state of a 3D thumbnail that the user wants to memorize or display among various 3D thumbnails. In addition, the user can search for a 3D thumbnail to which a bookmark command is input among a plurality of 3D thumbnails.

The image display apparatus 100 may display a plurality of view images constituting a 3D thumbnail on the display unit 180 (S210). The multiple view image may be an image obtained by separating the image corresponding to the predetermined reproduction time extracted by the thumbnail generating unit 173 based on the video signal stored in the storage unit 150 into a plurality of views.

The image display apparatus 100 may determine whether a bookmark command is input to the image display apparatus 100 (S220). The bookmark command can be input to the image display device 100 through the remote control device 200. [ For example, the user can adjust the remote controller 200 so that a pointer corresponding to a signal transmitted from the remote controller 200 is located in a 3D thumbnail to input a bookmark command. The user can operate the button or key of the remote control device 200 corresponding to the bookmark command when the pointer is positioned on the 3D thumbnail to which the bookmark command is input.

When the bookmark command is inputted through the remote controller 200, the image display apparatus 100 can change the display state of the 3D thumbnail corresponding to the input bookmark command (S230). In the present embodiment, a 3D thumbnail is a thumbnail to which a stereoscopic effect is given as if it is located at a predetermined distance from the display unit 180 toward the user. The image display apparatus 100 can change the display state of the 3D thumbnails as if some edges of the 3D thumbnails are bent. Also, the image display apparatus 100 can bookmark the playback time of the selected 3D thumbnail.

Therefore, the user can visually check the 3D thumbnail inputted with the bookmark command. In addition, the bookmarked playback point can be searched for later.
