Abstract

The present disclosure relates to an image display device including a display unit for playing video and a control method thereof, and the method may include selecting at least one of characters contained in video, searching at least one region containing the selected character within the entire region of a frame using at least one frame provided in the video, extracting a major playback section containing the selected character based on at least one of the size and location of the retrieved at least one region, and playing the extracted major playback section.

First claim

What is claimed is:

1. A method for controlling a display device, the method comprising:
identifying portions of a video that include a person selected by a user;
defining a major playback section of the video as including one or more of the identified portions of the video and that satisfy a preset criteria, wherein the preset criteria comprise at least one of a length of a scene or portion of the video including the selected person, a position of the selected person in a scene or portion of the video, or a proportion of the selected person in a scene or portion of the video;
displaying, on a display of the display device, the major playback section of the video;
displaying a progress bar indicating a playback status of the video while displaying the major playback section of the video, wherein the major playback section comprises a plurality of sections that are spaced apart from each other; and
displaying a plurality of indicators including a first indicator and a second indicator, each indicator accompanying a corresponding one of the plurality of sections, and each indicator indicating a significance level of the corresponding one of the plurality of sections with respect to the selected person, wherein a first size of the first indicator indicating a first significance level is different from a second size of the second indicator indicating a second significance level.

2. The method of claim 1 ,
wherein the progress bar comprises a first progress bar corresponding to an entire playback section of the video and a second progress bar corresponding to the major playback section.

3. The method of claim 2 , further comprising:
displaying the first progress bar and the second progress bar overlappingly; and
displaying the second progress bar overlapping a first portion of the first progress bar distinguishably such that the second progress bar is distinguishable within the first progress bar from a second portion of the first progress bar that represents a section of the video that does not correspond to the major playback section.

4. The method of claim 2 , wherein:
the first progress bar and the second progress bar are displayed independently such that the first progress bar indicates a currently played position of the video within the entire playback section of the video, and the second progress bar indicates the currently played position within the major playback section; and
each of the plurality of sections corresponds to one of the second progress bar.

5. The method of claim 1 , wherein the significance level is determined based on at least a size or a location of the selected person in a scene or portion of the video.

6. The method of claim 1 , wherein the displaying the major playback section comprises displaying frames included in the plurality of sections consecutively.

7. The method of claim 1 , further comprising:
editing the major playback section in response to a user input received via the progress bar.

8. The method of claim 1 , wherein the selection of the person comprises:
identifying a person or a face of the person included in a paused scene of the video that is paused during playback of the video;
displaying a graphic object for selecting the identified person on the paused screen; and
selecting the identified person in response to a touch applied to the graphic object.

9. An image display device, comprising:
a display configured to display video; and
a controller configured to:
identify portions of the video that include a person selected by a user;
define a major playback section of the video as including one or more of the identified portions of the video and that satisfy a preset criteria, wherein the preset criteria comprise at least a length of a scene or portion of the video including the selected person, a position of the selected person in a scene or portion of the video, or a proportion of the selected person in a scene or portion of the vide;
cause the display to display the major playback section of the video;
cause the display to display a progress bar indicating a playback status of the video while displaying the major playback section of the video, wherein the major playback section comprises a plurality of sections that are spaced apart from each other; and
cause the display to display a plurality of indicators including a first indicator and a second indicator, each indicator accompanying a corresponding one of the plurality of sections, and each indicator indicating a significance level of the corresponding one of the plurality of sections with respect to the selected person, wherein a first size of the first indicator indicating a first significance level is different from a second size of the second indicator indicating a second significance level.

10. The image display device of claim 9 , wherein
the progress bar comprises a first progress bar corresponding to an entire playback section of the video and a second progress bar corresponding to the major playback section.

11. The image display device of claim 10 , wherein the controller is further configured to cause the display to:
display the first progress bar and the second progress bar overlappingly; and
display the second progress bar overlapping a first portion of the first progress bar distinguishably such that the second progress bar is distinguishable within the first progress bar from a second portion of the first progress bar that represents a section of the video that does not correspond to the major playback section.

12. The image display device of claim 10 , wherein:
the first progress bar and the second progress bar are displayed independently such that the first progress bar indicates a currently played position of the video within the entire playback section of the video, and the second progress bar indicates the currently played position within the major playback section; and
each of the plurality of sections corresponds to one of the second progress bar.

13. The image display device of claim 9 , wherein the significance level is determined based on at least a size or a location of the selected person in a scene or portion of the video.

14. The image display device of claim 9 , wherein the controller is further configured to cause the display to display frames included in the plurality of sections consecutively.

15. The image display device of claim 9 , wherein the controller is further configured to edit the major playback section in response to a user input received via the progress bar.

16. The image display device of claim 9 , wherein the controller is further configured to:
identify a person or a face of the person included in a paused scene of the video that is paused during playback of the video;
cause the display to display a graphic object for selecting the identified person on the paused screen; and
select the identified person in response to a touch applied to the graphic object.
