8. The method of claim 7, wherein each of the first identification information, the second identification information and the transmission state information comprises at least one of characters, a sign, and image information, and the image information comprises at least one of an emoticon, an icon, a flash icon, and image information.

9. The method of claim 1, further comprising displaying the media signal on a screen.

10. The method of claim 1, wherein the detecting the pattern comprises:

detecting a first pattern from the input image; and

detecting a second pattern corresponding to the first pattern from the input image.

11. The method of claim 10, wherein the extracting the identified region comprises extracting a region defined by positions of the first and second patterns.

12. The method of claim 11, wherein the extracting the identified region comprises extracting a rectangular region having a straight line connecting the first pattern and the second pattern as a diagonal line.

13. The method of claim 1, wherein the extracting the identified region comprises extracting a region defined by a position and a direction of the pattern.

14. The method of claim 13, wherein the extracting the identified region comprises extracting a region which is variable in vertical and horizontal directions about the position of the pattern depending on the direction of the pattern.

15. The method of claim 13, wherein, if the pattern corresponds to an angle bracket, the extracting the identified region comprises extracting a rectangular region having a straight line connecting a center point of the angle bracket to a corner of an area located between two straight lines that extend from two lines that are elements of the angle bracket from the center point, as a diagonal line.

16. The method of claim 13, wherein, if the pattern corresponds to a curved line, the extracting the identified region comprises extracting a rectangular region having a straight line connecting a center point of the curved line to a corner of an area located between two straight lines that extend from two lines connecting each of two end points of the curved line to the center point, as a diagonal line.

17. The method of claim 1, wherein the generating the media signal comprises generating the media signal as an image file or a text file, from the input image.

18. The method of claim 17, wherein the generating the media signal comprises:

extracting second information from a media signal generating apparatus, the second information corresponding to first information included in the identified region; and

generating the media signal using the second information.

19. An apparatus for generating a media signal comprising:

a pattern detector which detects a pattern indicating a request for a media signal to be generated from an input image;

a region extractor which extracts a region identified by the detected pattern; and

a media signal generator which generates the media signal for the extracted region.

20. The apparatus of claim 19, wherein the pattern detector compares the pattern which is included in the input image with stored media signal request patterns and determines whether the pattern included in the input image corresponds to one of the stored media signal request patterns.

21. The apparatus of claim 19, wherein the pattern comprises a predetermined sign and a predetermined action and the predetermined sign comprises at least one of a bracket and a figure.

22. The apparatus of claim 19, further comprising a communication unit which transmits the media signal to an external terminal or an external server through a communication network.

23. The apparatus of claim 22, further comprising a display which outputs the media signal or a state of transmission of the media signal as graphic information to the external terminal or the external server.

24. The apparatus of claim 23, wherein the graphic information comprises first identification information which identifies the external terminal, the external server or a user of the external terminal.

25. The apparatus of claim 24, wherein the graphic information further comprises second identification information which identifies the apparatus or a user of the apparatus, and transmission state information representing that the media signal is being transmitted from the apparatus or the user of the apparatus that is identified by the second identification information to the external terminal, the external server or the user of the external terminal that is identified by the first identification information.

26. The apparatus of claim 25, wherein each of the first identification information, the second identification information and the transmission state information comprise at least one of characters, a sign, and image information, and the image information comprises at least one of an emoticon, an icon, a flash icon, and image information.

27. The apparatus of claim 19, wherein the pattern detector detects a first pattern from the input image and then detects a second pattern corresponding to the first pattern from the input image.

28. The apparatus of claim 27, wherein the region extractor extracts a region defined by the positions of the first and second patterns.

29. The apparatus of claim 28, wherein the region extractor extracts a rectangular region having a straight line connecting the first pattern and the second pattern as a diagonal line.
