Abstract

A method for receiving a sound generated from a moving subject and an electronic device implementing the same are provided. The method includes confirming a position of a subject so as to intensively receive a sound generated from the subject, photographing a moving image, selecting at least one subject among subjects included in the photographed moving image, obtaining movement information of the selected subject, and adjusting a major sound capture region based on the obtained movement information of the subject.

First claim

What is claimed is:

1. A method of receiving a sound of a subject, the method comprising:
photographing a moving image;
selecting at least one subject among subjects included in the photographed moving image;
obtaining movement information of the selected at least one subject;
adjusting a major sound capture region based on the obtained movement information of the at least one subject;
measuring a moving speed of the at least one subject based on the obtained movement information of the at least one subject;
determining whether the at least one subject, having the moving speed equal to or greater than a threshold, moves out of a boundary region;
adjusting, when the at least one subject having a moving speed equal to or greater than the threshold moves out of the boundary region, the major sound capture region based on another boundary region; and
adjusting, when the at least one subject having a moving speed less than the threshold moves within the boundary region, the major sound capture region based on the movement information of the at least one subject.

2. The method of claim 1 , further comprising:
re-adjusting the major sound capture region to a pre-set boundary region to correspond to a moving direction of the at least one subject.

3. The method of claim 2 , wherein the boundary region is differently set according to a distance between the at least one subject and the electronic device.

4. The method of claim 1 , further comprising:
re-adjusting the major sound capture region based on a photographing range.

5. The method of claim 1 , wherein the threshold comprises a minimum moving speed of the at least one subject in which the at least one subject cannot be continuously tracked.

6. The method of claim 1 , wherein the adjusting of the major sound capture region comprises:
confirming a position of the at least one subject based on the obtained movement information of the at least one subject; and
adjusting the major sound capture region by controlling at least two microphones based on the confirmed position of the at least one subject.

7. The method of claim 6 , wherein the microphones are directional microphones, and intensively receive a sound generated from a direction directed by the microphones.

8. The method of claim 1 , further comprising:
obtaining sound information of the selected at least one subject;
determining whether the at least one subject moves out of a photographing range; and
adjusting the major sound capture region based on the obtained sound information of the at least one subject when the at least one subject moves out of the photographing range.

9. The method of claim 8 , wherein the sound information comprises pitch, tune, timbre, and vibration.

10. At least one non-transitory computer readable storage medium for storing a computer program of instructions configured to be readable by at least one processor for instructing the at least one processor to execute a computer process for performing the method of claim 1 .

11. An electronic device for receiving a sound of a subject, the electronic device comprising:
a camera configured to photograph a moving image;
a microphone configured to receive a sound;
a display unit configured to display the moving image photographed by the camera; and
a control unit configured to:
control the camera to photograph the moving image,
select at least one subject included in the photographed moving image,
obtain movement information of the selected at least one subject,
adjust a major sound capture region based on the obtained movement information of the at least one subject,
measure a moving speed of the at least one subject based on the obtained movement information of the at least one subject,
determine whether the at least one subject, having the moving speed equal to or greater than a threshold, moves out of a boundary region,
adjust, when the subject having the moving speed equal to or greater than the threshold moves out of the boundary region, the major sound capture region based on another boundary region, and
adjust, when the at least one subject having a moving speed less than the threshold moves within the boundary region, the major sound capture region based on the movement information of the at least one subject.

12. The electronic device of claim 11 ,
wherein the control unit is further configured to re-adjust the major sound capture region to a boundary region pre-set to correspond to a moving direction of the at least one subject, and
wherein the boundary region is differently set according to a distance between the at least one subject and the electronic device.

13. The electronic device of claim 11 , wherein the control unit is further configured to re-adjust the major sound capture region based on a photographing range.

14. The electronic device of claim 11 ,
wherein the threshold comprises a minimum moving speed of the at least one subject in which the at least one subject cannot be continuously tracked.

15. The electronic device of claim 11 , wherein the control unit is further configured to:
confirm a position of the at least one subject based on the obtained movement information of the at least one subject, and
adjust the major sound capture region by controlling at least two microphones based on the confirmed position of the at least one subject.

16. The electronic device of claim 15 , wherein the microphones are directional microphones, and intensively receive a sound generated from a direction directed by the microphones.

17. The electronic device of claim 11 , wherein the control unit is further configured to:
obtain sound information of the selected at least one subject, to determine whether the at least one subject moves out of a photographing range, and
adjust the major sound capture region based on the obtained sound information of the at least one subject when the at least one subject moves out of the photographing range,
wherein the sound information comprises pitch, tune, timbre, and vibration.
