Abstract

Provided are image processing methods and apparatuses for playing/recording a moving picture using caption search, which are capable of easily playing and recording the moving picture from a desired location by searching through captions of the moving picture. The method searches for a caption corresponding to a search key word among captions of the moving picture based on the search key word, displays a search-result list, and records at least one item included in the displayed search-result list according to a selected recording mode. Accordingly, a desired location of the moving picture can be played and/or recorded through caption search. Because the moving picture can be played from a predetermined location using caption search and a user'"'"'s voice can be recorded and output, efficient foreign-language learning may be possible.

Claims

1. A method of recording a moving picture using a caption search, the method comprising:

searching for a caption corresponding to a search key word among captions of the moving picture based on the search key word;

displaying a search-result list; and

recording at least one item included in the displayed search-result list according to a selected recording mode.

2. The method according to claim 1, wherein the recording the at least one item included in the displayed search-result list according to a selected recording mode comprises recording all items included in the search-result list while playing the all items when an event instructing full play and record occurs.

3. The method according to claim 2, wherein when the event instructing full play and record occurs, all the items included in the search-result list are recorded as one moving-picture file.

4. The method according to claim 2, wherein when an event instructing full play and record occurs, a caption included in each item of the search-result list is mixed with a moving picture corresponding to the caption.

5. The method according to claim 1, wherein the recording at least one item included in the displayed search-result list according to a selected recording mode comprises recording, when an event instructing a play and a record occurs, a selected one of the items included in the search-result list while playing the selected item.

6. The method according to claim 1, further comprising:

storing at least one moving picture recorded according to the selected recording mode; and

displaying a list of the stored at least one moving picture.

7. A method of playing a moving picture using a caption search, the method comprising:

searching for a caption corresponding to a search key word among captions of the moving picture based on the search key word;

displaying a search-result list; and

playing at least one selected item included in the displayed search-result list according to a selected playback mode.

8. The method according to claim 7, wherein the playback mode comprises at least one of a repeat play and a sequential play.

9. The method according to claim 7, wherein the playing at least one selected item included in the displayed search-result list according to a selected playback mode comprises playing one of the at least one selected item, pausing for a predetermined time, and then playing the next item.

10. The method according to claim 7, further comprising recording a user'"'"'s voice and outputting the recorded user'"'"'s voice.

11. The method according to claim 7, further comprising recording and outputting a user'"'"'s voice for repetitive foreign-language learning.

12. The method according to claim 7, wherein the searching for a caption corresponding to a search key word among captions of the moving picture comprises searching for a play time-point of the moving picture to display the search key word.

13. The method according to claim 7, wherein the displaying the search-result list comprises displaying a caption including the search key word and a screen shot corresponding to a play time-point of the moving picture onto which the caption is displayed.

14. The method according to claim 7, wherein the displaying a search-result list comprises displaying a caption including the search key word and a play time-point of the moving picture onto which the caption is displayed.

15. An image processing apparatus having a function of recording a moving picture using caption search, the apparatus comprising:

a controller configured to search for a caption corresponding to a search key word among captions of the moving picture based on the search key word, configured to display a search-result list, and configured to record at least one item included in the displayed search-result list according to a selected recording mode; and

a storage unit configured to store the recorded at least one item.

16. The apparatus according to claim 15, wherein the controller records, when an event instructing a full play and a record occurs, all items included in the search-result list while playing the items.

17. The apparatus according to claim 16, wherein the controller records, when the event instructing the full play and the record occurs, all the items included in the search-result list as one moving-picture file.

18. The apparatus according to claim 16, wherein the controller mixes, when the event instructing the full play and the record occurs, a caption included in each item of the search-result list with a moving picture corresponding to the caption.

19. The apparatus according to claim 15, wherein the controller records, when an event instructing to play a selected item and to record the selected item occurs, a selected item of the items included in the search-result list while playing the selected item.

20. An image processing apparatus having a function of playing a moving picture using caption search, the apparatus comprising:

a controller configured to search for a caption corresponding to a search key word among captions of the moving picture based on the search key word, configured to display a search-result list, and configured to play at least one selected item included in the displayed search-result list according to a selected playback mode; and

a display unit configured to display the search-result list provided from the controller.

21. The apparatus according to claim 20, wherein the playback mode comprises at least one of a repeat play and a sequential play.

22. The apparatus according to claim 20, wherein the controller plays one of the at least one selected item, pauses for a predetermined time, and then plays the next item.

23. The apparatus according to claim 20, wherein the controller records a user'"'"'s voice and outputs the recorded user'"'"'s voice.

24. The apparatus according to claim 20, wherein the controller provides the display unit with a caption including the search key word and a screen shot corresponding to a play time-point of the moving picture onto which the caption is displayed.
