saving the acquired image having the updated digital code in the prescribed region as a single image file.

8. The method of claim 1 , further comprising determining a position of the prescribed region such that the prescribed region does not include a focal point of the acquired image.

9. The method of claim 1 , wherein the digital code comprises a QR (quick response) code.

10. A mobile terminal comprising:

a display;

a memory; and

a controller configured to:

acquire an image;

acquire side information related to the acquired image;

generating an optically readable digital code corresponding to the acquired side information;

cause the display to display the acquired image and the digital code wherein the digital code is positioned at a first position within the acquired image;

move the digital code to a second position within the acquired image according to a touch input to the digital code received via the display;

replace a portion of the acquired image displayed on a prescribed region corresponding to the second position of the acquired image with the digital code and overwrite image information of the prescribed region with an image of the digital code; and

cause the memory to save the acquired image having the image of the digital code in the prescribed region as a single image file.

11. The mobile terminal of claim 10 , further comprising:

a user input unit configured to receive a user input,

wherein the controller is further configured to determine the prescribed region according to the user input.

12. The mobile terminal of claim 10 , further comprising:

a wireless communication unit configured to exchange data with an external device,

wherein the controller is further configured to upload the acquired image via the wireless communication unit, and

wherein the side information comprises upload information associated with the uploaded acquired image.

13. The mobile terminal of claim 12 , wherein the acquired image is uploaded to an upload service comprising a social network service (SNS), a blog service, a messaging service, an email service, a cloud-computing service, or a short range communication service.

14. The mobile terminal of claim 13 , further comprising:

a user input unit configured to receive a user input,

wherein the upload information comprises text information input via the user input unit, a URL of a webpage associated with the uploaded acquired image, or a URL associated with the upload service.

15. The mobile terminal of claim 13 , wherein the upload information comprises information identifying a counterpart of a communication via the email service, the messaging service, or the short range communication service.

16. The mobile terminal of claim 10 , further comprising:

a user input unit configured to receive a user input,

wherein the side information comprises text related to the acquired image and the text is inputted via the user input unit.

17. The mobile terminal of claim 10 , further comprising a camera configured to capture images;

wherein the acquired image comprises at least a still image or a video captured via the camera;

wherein the controller is further configured to acquire the image by causing the camera to capture the image or by selecting the image from a plurality of images saved in a memory.

18. The mobile terminal of claim 10 , wherein the digital code comprises a QR (quick response) code.

19. The mobile terminal of claim 10 , wherein the controller is further configured to determine a position of the prescribed region such that the prescribed region does not include a focal point of the acquired image.

20. The mobile terminal of claim 10 , wherein the controller is further configured to:

acquire updated side information related to the acquired image;

generate an updated optically readable digital code corresponding to the updated side information;

replace the digital code of the acquired image with the updated digital code; and

cause the memory to save the acquired image having the updated digital code in the prescribed region as a single image file.
