In addition, a predetermined 3D object may be highlighted as the up, down, left, or right buttons provided in the general remote control 201 are manipulated. The controller 170 may determine that the rotation command of the highlighted 3D object is input to the image display apparatus 100.

The controller 170 processes the image signal output to the display unit 180 to be recognized by the user as the 3D object rotates (S230). More specifically, the controller 170 processes the image signal output to the display unit 180 so that the multi-view image constituting the 3D object is changed. As the multi-view image is changed, the 3D object is recognized by the user as if it is rotating.

In addition, the controller 170 processes the image signal output to the display unit 180 to change the thumbnail image included in the rotating 3D object (S240). In the present embodiment, the controller 170 may determine the rotation direction of the 3D object and change the thumbnail image included in the rotating 3D object according to the determined rotation direction.

For example, the multi-view image constituting the 3D object may be changed such that the 3D object including the thumbnail image corresponding to at least three playback views of the predetermined content rotates in a clockwise direction. In this case, the thumbnail image corresponding to the playback time after the playback time corresponding to the thumbnail image included in the 3D object before the rotation may be included in the rotating 3D object. Therefore, the user can check the thumbnail image of the content that is expanded after the thumbnail image included in the 3D object before rotation.

As illustrated in FIG. 6, the display unit 180 of the image display apparatus 100 may display a movie list screen 300. The user may select a cable folder 301 for which the movie list is to be checked among the folders included in the movie list screen 300. The controller 170 determines that the cable folder 301 selection command is input to the image display apparatus 100.

The OSD generator 174 extracts a thumbnail image of the movie content included in the cable folder 301 and generates an OSD signal so that the 3D object composed of the extracted thumbnail image is recognized by the user. The OSD signal generated by the OSD generator 174 is converted into a 3D video signal format that can be output to the display 180 through the formatter 175. The formatter 175 outputs the converted 3D image signal to the display unit 180.

The display unit 180 may display the multi-view image on the plane D1 such that the 3D object is recognized by the user according to the 3D image signal output through the formatter 175. In the present embodiment, the multi-view image is a left eye image viewed through the left eye of the user and a right eye image viewed through the right eye of the user so that the user can recognize the 3D object in three dimensions.

The 3D objects 311, 312, and 313 including thumbnails composed of the multi-view images are recognized by the user as if they have a different depth from that of the plane D1. In this embodiment, the user recognizes as if the 3D objects 311, 312, 313 are located protruding toward the user.

Also, the 3D object 311 in which the selection command is input may rotate. In the present embodiment, when the selection command of the predetermined 3D object is input, the controller 170 may recognize that the rotation command of the selected 3D object is input. The controller 170 may change the image signal output to the display unit 180 to be recognized by the user as the 3D object determined to be the rotation command is rotated. When the image signal output to the display unit 180 is changed, the multi-view image constituting the 3D object is changed. When the multiview image is changed, the user recognizes that the 3D object including the changed multiview image is rotated.

The OSD generator 174 may determine a rotation direction of the 3D object and re-extract a thumbnail image of a playback time corresponding to the determined rotation direction. The thumbnail image re-extracted by the OSD generator 174 is included in a rotating 3D object.

For example, as illustrated in FIG. 6, the 3D object 311 to which a selection command is input is a polyhedron having each side of thumbnail images S0, S1, and S2 corresponding to at least three playback points of predetermined content. The thumbnail image may be displayed on the 3D object 311 in a predetermined order.

In the present embodiment, among the thumbnail images S0, S1, and S2 included in the 3D object 311, the thumbnail image S0 having the fastest playback time is displayed on the upper surface of the 3D object 311, and is displayed at the next playback time. The corresponding thumbnail image S1 is displayed on the left side of the 3D object 311, and then the thumbnail image S2 corresponding to the playback time is displayed on the right side of the 3D object 311.

The shape of the 3D object 311 determined as input of the rotation command is changed as shown in FIG. 7. The changed 3D object 321 is a cylinder whose pillar surface is formed of a thumbnail image corresponding to a predetermined content.

When the cylinder is rotated in the clockwise direction, the OSD generator 174 re-extracts the S3 thumbnail image corresponding to the playback time after the playback time corresponding to the S2 thumbnail image. The OSD generator 174 changes the OSD signal output to the formatter 175 so that the re-extracted S3 thumbnail image is included in the 3D object 311. The formatter 175 converts the OSD signal changed by the OSD generator 174 to match the format of the display 180 and outputs the converted OSD signal to the display 180.

As illustrated in FIG. 7, the display unit 180 changes the multi-view image constituting the 3D object 321 so that the user can recognize the rotating 3D object 321. In addition, as the 3D object 321 rotates, the thumbnail image included in the 3D object 321 is also changed. The user may check the thumbnail image of the predetermined content in the order of playing time through the rotating 3D object 321.

FIG. 8A illustrates another example of the movie list screen 350 displayed on the image display apparatus 100. The movie list screen 350 displays an item including a title 351 of a content included in a predetermined content folder and a thumbnail image 352 of the corresponding content.

FIG. 8B is a diagram illustrating a screen 360 that a user watches when content corresponding to Movie 13 is played on the video display device 100. The controller 170 may process an image signal output to the display unit 180 to display the screen 360 including the image C13 corresponding to Movie 13 on the display unit 180. Also, the OSD generator 174 generates an OSD signal and outputs the OSD signal to the formatter 175 so that the object 361 capable of controlling content reproduction can be displayed on the display 180.

The controller 170 may determine whether another movie preview command is input to the image display apparatus 100. If another movie preview command is input to the image display apparatus 100, the OSD generator 174 may generate a 3D object including thumbnail images C14, C23, and C24 corresponding to Movie 14, Movie 23, and Movie 24. 362 generates an OSD signal for the user to be recognized.

The OSD generator 174 may change an OSD signal generated so that the 3D object 362 rotates when the 3D object rotation command is input. The thumbnail image included in the 3D object 362 may be changed when the 3D object 362 rotates.

When the controller 170 determines that a predetermined thumbnail image selection command is input among the thumbnail images C14, C23, and C24 included in the 3D object 362, the controller 170 may play content corresponding to the selected thumbnail image according to the selection command. . That is, when the thumbnail image C14 selection command is input to the image display apparatus 100, the image display apparatus 100 may play Movie 14.

In addition, the image display apparatus and its operation or control method according to the present invention are not limited to the configuration and method of the above-described embodiments, but the embodiments may be modified in various ways. All or some of these may optionally be combined.

Meanwhile, the present invention can be embodied as processor readable codes on a processor readable recording medium included in the image display device.
