Abstract

The present disclosure relates to a mobile terminal and an audio zooming method thereof capable of effectively capturing audio based on an image while capturing and reproducing video. According to the present disclosure, if an event for changing the capture location or range or capture mode of a subject occurs when capturing the subject while capturing the sound of the subject in a predetermined sound capture range, the sound of the subject may be captured by changing a sound capture angle and automatically controlling a sound capture range according to the relevant event, and if an event for changing the capture location or range or capture mode of a subject occurs, the sound of the subject may be captured by automatically controlling a sound capture range according to the event.

Claims

1. An audio zooming method of a reproduced image, the method comprising:

displaying the reproduced image;

configuring an edit region in part of the displayed image;

configuring a sound capture range in the configured edit region; and

reproducing a sound in the configured sound capture range from a stored original sound.

2. The method of claim 1, wherein the edit region is configured by a menu selection or touch gesture as a region for enlargement, removal and new focus, and

the sound capture region is configured with a location and size corresponding to the edit region.

3. The method of claim 1, wherein only a sound generated from the relevant region is selectively reproduced from the stored original sound when the edit region is an enlargement region or new focus region.

4. The method of claim 1, wherein only a sound generated from the relevant region is removed for reproduction from the stored original sound when the edit region is a removal region.

5. An audio zooming method of a reproduced image, the method comprising:

displaying a first and a second image captured from front and rear cameras at the same time;

configuring a sound capture location and range based on a user'"'"'s input to an image displayed on a sub screen between the first and the second image; and

reproducing the sound of the first image and the second image according to the configured sound capture location and range from the stored original sound.

6. The method of claim 5, wherein the user input comprises an input for image selection, image size control and image location control.

7. The method of claim 5, wherein the first image is displayed on a main screen as an image of the rear camera, and the second image is displayed on a sub screen as an image of the front camera.

8. The method of claim 5, wherein said capturing the sound of the second image forms a directivity in the user'"'"'s selected first or second image direction to reproduce only the sound of the first image or second image.

9. The method of claim 5, wherein said capturing the sound of the second image controls the sound volume of the second image in proportion to the size of the second image when the size of the second image is changed according to the user'"'"'s touch input.

10. The method of claim 5, wherein said capturing the sound of the second image changes a directivity of the subject of the first image based on the location of the user'"'"'s selected second image to reproduce the sound of the first image.

11. A mobile terminal, comprising:

a memory configured to store a capture image;

a display unit configured to display the stored image; and

a controller configured to reproduce the sound of the image in a sound capture range corresponding to the edit region from an original sound stored in the memory when a specific edit region is set to the displayed image.

12. The mobile terminal of claim 11, wherein the edit region comprises a region for enlargement, removal and new focus.

13. The mobile terminal of claim 11, wherein the controller configures an edit region according to a user'"'"'s menu selection or touch gesture, and the sound capture region is configured with a location and size corresponding to the configured edit region.

14. The mobile terminal of claim 11, wherein only a sound generated from the relevant region is selectively reproduced from the stored original sound when the edit region is an enlargement region or new focus region, and only a sound generated from the relevant region is removed for reproduction from the stored original sound when the edit region is a removal region.

15. A mobile terminal, comprising:

a memory configured to store a first and a second image captured from front and rear cameras;

a display unit configured to display the stored first and the second image; and

a controller configured to configure a sound capture location and range based on a user'"'"'s input to an image displayed on a sub screen between the first and the second image to reproduce the sound of the first image and the second image according to the configured sound capture location and range from the original sound stored in the memory.

16. The mobile terminal of claim 15, wherein the user input comprises an input for image selection, image size control and image location control.

17. The mobile terminal of claim 15, wherein the first image is displayed on a main screen as an image of the rear camera, and the second image is displayed on a sub screen as an image of the front camera.

18. The mobile terminal of claim 15, wherein the controller forms a directivity in the user'"'"'s selected first or second image direction to reproduce only the sound of the first image or second image.

19. The mobile terminal of claim 15, wherein the controller controls the sound volume of the second image in proportion to the size of the second image when the size of the second image is changed according to the user'"'"'s touch input.

20. The mobile terminal of claim 15, wherein the controller changes a directivity of the subject of the first image based on the location of the user'"'"'s selected second image to reproduce the sound of the first image.
