Abstract

A code recognition method for adjusting a User Interface (UI) rotation angle of a code recognition application depending on the direction of a recognition code or text entered through a camera is provided. The code recognition method includes detecting at least a portion of the recognition code from an image including the recognition code; determining a code rotation angle of the recognition code; and extracting the recognition code or a text from the image including the recognition code based on the code rotation angle of the recognition code.

Claims

1. A method for recognizing a recognition code in a mobile terminal, the method comprising:

detecting at least a portion of the recognition code from an image including the recognition code;

determining a code rotation angle of the recognition code; and

extracting the recognition code or a text from the image including the recognition code based on the code rotation angle of the recognition code.

2. The method of claim 1, before detecting the at least portion of the recognition code from the image including the recognition code, further comprising:

receiving a user input for requesting to perform a code recognition mode for detecting the recognition code; and

executing a code recognition application for detecting the recognition code.

3. The method of claim 2, after determining the code rotation angle of the recognition code, further comprising:

determining whether a User Interface (UI) rotation angle of the code recognition application is equal to the code rotation angle of the recognition code; and

rotating, if the UI rotation angle is not equal to the code rotation angle, a UI of the code recognition application so that the UI rotation angle of the code recognition application is equal to the code rotation angle.

4. The method of claim 1, wherein extracting the recognition code or the text comprising:

determining a scan direction of the image based on the code rotation angle of the recognition code;

extracting the text by scanning the image in the scan direction; and

outputting the recognition code or the text.

5. The method of claim 1, after detecting the at least a portion of the recognition code from the image including the recognition code, further comprising:

detecting a text line including the text from the image including the recognition code;

determining a rotation angle of the text line; and

extracting the recognition code or the text based on the rotation angle of the text line.

6. The method of claim 5, after determining the rotation angle of the text line, further comprising:

determining whether a UI rotation angle of a code recognition application is equal to the rotation angle of the text line; and

rotating, if the UI rotation angle is not equal to the rotation angle of the text line, a UI of the code recognition application so that the UI rotation angle is equal to the rotation angle of the text line.

7. A mobile terminal for recognizing a recognition code, the mobile terminal comprising:

a camera module configured to receive an image including the recognition code; and

a controller configured to;

detect at least a portion of the recognition code from the image including the recognition code,

determine a code rotation angle of the recognition code, and

extract the recognition code or a text from the image including the recognition code based on the code rotation angle of the recognition code.

8. The mobile terminal of claim 7, further comprising:

an input/output module configured to receive a user input for requesting to perform a code recognition mode for detecting the recognition code.

9. The mobile terminal of claim 8, wherein the controller executes a code recognition application for detecting the recognition code in response to the user input.

10. The mobile terminal of claim 9, wherein the controller determines whether a User Interface (UI) rotation angle of the code recognition application is equal to the code rotation angle of the recognition code, and rotates, if the UI rotation angle is not equal to the code rotation angle, a UI of the code recognition application so that the UI rotation angle of the code recognition application is equal to the code rotation angle.

11. The mobile terminal of claim 7, wherein the controller determines a scan direction of the image based on the code rotation angle of the recognition code, and extracts the text by scanning the image in the scan direction.

12. The mobile terminal of claim 7, wherein the controller detects a text line including the text from the image including the recognition code, determines a rotation angle of the text line, and extracts the recognition code or the text based on the rotation angle of the text line.

13. The mobile terminal of claim 12, wherein the controller determines whether a UI rotation angle of a code recognition application is equal to the rotation angle of the text line, and rotates, if the UI rotation angle is not equal to the rotation angle of the text line, a UI of the code recognition application so that the UI rotation angle is equal to the rotation angle of the text line.

14. A method for recognizing a recognition code in a mobile terminal, the method comprising:

detecting at least a portion of a recognition code from an image including the recognition code;

determining a code rotation angle of the recognition code;

determining whether a User Interface (UI) rotation angle of a code recognition application is equal to the determined code rotation angle of the recognition code; and

if the UI rotation angle is not equal to the code rotation angle, rotating a UI of the code recognition application so that the UI rotation angle of the code recognition application is equal to the code rotation angle.
