Abstract

The present disclosure relates to a method for processing sound source in terminal capable of receiving an outside sound source through at least two microphones and displaying a position of the outside sound source on a display unit, and a terminal using the same, wherein the terminal includes: at least two microphones configured to receive an outside sound source; a display unit configured to display a predetermined data; and a controller configured to obtain position information of the sound source using at least one of an amplitude, a phase and a period of the outside sound source received from the two microphones, and controllably display the position information of the sound source on a display unit.

Claims

1. A method for processing a sound source in a terminal, the method comprising:

obtaining position information of an outside sound source;

displaying a sound source storage icon capable of setting up the position information on a display unit; and

selectively obtaining the outside sound source using the sound source storage icon.

2. The method of claim 1, wherein the step of obtaining position information of an outside sound source comprises:

receiving the outside sound source through at least two microphones; and

determining the position information of the outside sound source using at least one of amplitude difference, a phase difference, a period difference and a time difference of sound received from the two microphones.

3. The method of claim 1, wherein the step of obtaining position information of an outside sound source comprises:

further obtaining an image corresponding to the outside sound source through a camera of the terminal;

recognizing a face included in the image using a face recognition program; and

determining position information of the outside sound source in further consideration of a position of the face.

4. The method of claim 1, wherein the step of obtaining position information of an outside sound source comprises:

obtaining position information of the outside sound source inputted to the microphones using at least two microphones;

displaying a sound source transmission icon representing the outside sound source on the display unit; and

transmitting only the selected sound source through the wireless communication unit of the terminal by selecting the sound source transmission icon, based on the position information of the outside sound source.

5. The method of claim 1, further comprising:

reproducing the outside sound source through an audio output module of the terminal and displaying the sound source reproduction icon on the display unit of the terminal based on the position information; and

discontinuing the output of the selected sound source if the sound source reproduction icon is selected, or reproducing only the selected sound source.

6. A method for processing a sound source in a terminal, the method comprising:

receiving an outside sound source through at least two microphones;

selecting at least one of a directivity mode, a normal mode, and a noise removal mode from a sound source process program for controlling the microphones, and obtaining the outside sound source responsive to the selected mode; and

displaying on a display unit a microphone mode identifier for displaying the selected mode.

7. The method of claim 6, wherein the directivity mode includes an inner focus mode and an outer focus mode.

8. The method of claim 6, further comprising:

analyzing the obtained outside sound source and displaying the analyzed sound source in microphone reception sensitivity bar; and

using the microphone reception sensitivity bar to control an amplification degree of the obtained sound source.

9. The method of claim 6, wherein the step of selecting at least one of a directivity mode, a normal mode, and a noise removal mode from a sound source program for controlling the microphones, and obtaining the outside sound source responsive to the selected mode, comprises:

detecting a user gesture by a detection sensor formed at the terminal; and

selecting the noise removal mode if the user gesture is detected, and obtaining the outside sound source responsive to the noise removal mode.

10. The method of claim 6, wherein the step of selecting at least one of a directivity mode, a normal mode, and a noise removal mode from a sound source program for controlling the microphones, and obtaining the outside sound source responsive to the selected mode, comprises:

obtaining a moving picture image included in the outside sound source;

executing a face recognition program pre-stored in a memory of the terminal to confirm whether a face is available in the moving picture image; and

selecting the directivity mode if it is confirmed that the face is available in the moving picture image.

11. A terminal, comprising:

at least two microphones configured to receive an outside sound source;

a display unit configured to display a predetermined data; and

a controller configured to obtain position information of the sound source using at least one of an amplitude, a phase and a period of the outside sound source received from the two microphones, and controllably display the position information of the sound source on a display unit.

12. The terminal of claim 11, further comprising:

a memory configured to store a face recognition program; and

a camera,

wherein the controller obtains an image corresponding to the outside sound source through the camera, uses the face recognition program pre-stored in the memory to recognize a face included in the image and determines the position information in consideration of a position of the recognized face.

13. The terminal of claim 11, wherein the controller displays a sound source storage icon indicating the outside sound source on the display unit based on the position information, and controllably obtains only the selected sound source or only the not-selected sound source if a select signal to the sound source storage icon is generated.

14. The terminal of claim 11, further comprising:

a sound source output module configured to output the outside sound source,

wherein the controller may display a sound source reproduction icon on the display unit based on the position information of the outputted sound source, and discontinue the output of the selected sound source or reproduce only the selected sound source.

15. The terminal of claim 11, further comprising:

a wireless communication unit configured to communicate with other terminals,

wherein the controller obtains the position information of the outside sound source and displays a sound source transmission icon representing the position information on the display unit if a conference call mode is entered, and transmits the outside sound source to other terminals only the selected sound source through the wireless communication unit, or transmits only the not-selected sound source to the other terminals if the sound source transmission icon is selected.

16. The terminal of claim 11, further comprising:

a memory configured to store a sound source process program including any one of a directivity mode, a normal mode and a noise removal mode,

wherein the controller obtains the outside sound source by selecting at least any one of the directivity mode, the normal mode and the noise removal mode and controlling the two microphones responsive to the selected mode, and displays on the display unit a microphone mode identifier configured to display the selected mode.

17. The terminal of claim 16, wherein the controller analyzes the obtained outside sound source and display the analyzed sound source on the display unit in a microphone reception sensitivity bar, and uses the microphone reception sensitivity bar to control the volume of the obtained sound source.
