Abstract

Various embodiments of the disclosure relate to an electronic device and an image capturing method thereof. The electronic device may include a plurality of cameras including a first camera and a second camera, a memory, and a processor. The processor is configured to perform high-speed shooting for image capture by changing a shooting speed of the first camera to a second frame rate greater than a first frame rate, in accordance with a change in information of at least one object in images captured using the second camera.

First claim

What is claimed is:

1. An electronic device, comprising:
a plurality of cameras including a first camera and a second camera;
a memory; and
a processor configured to:
set a first area of interest for images to be captured using the first camera and a second area of interest for images to be captured using the second camera, and
trace a motion path of at least one object in images captured using the second camera, and perform high-speed shooting for image capture by changing a shooting speed of the first camera to a second frame rate greater than a first frame rate by comparing the motion path of the at least one object and the first area of interest based on a distance and a direction.

2. The electronic device of claim 1 , wherein the processor is further configured to:
change a shooting speed of the first camera by detecting a motion of the at least one object in the second area of interest.

3. The electronic device of claim 2 , wherein the processor is further configured to determine a point in time for changing the shooting speed of the first camera by tracing the motion of the at least one object in the second area of interest.

4. The electronic device of claim 2 , wherein the processor is further configured to:
determine a point in time for changing the shooting speed of the first camera by comparing the motion path of the at least one object and the first area of interest based on the distance and the direction.

5. The electronic device of claim 4 , wherein the processor is further configured to change the shooting speed of the first camera at a point in time at which the at least one object is located within the distance, wherein the distance is less than a reference value from the first area of interest in accordance with the motion path.

6. The electronic device of claim 2 ,
wherein the second camera includes a wide-angle camera, and
wherein the processor is further configured set the second area of interest to include the first area of interest.

7. The electronic device of claim 2 ,
wherein the second camera includes a telephoto camera, and
wherein the processor is further configured to set the second area of interest to include the first area of interest.

8. The electronic device of claim 7 , wherein the processor is further configured to change the shooting speed of the first camera based on the motion of the at least one object.

9. The electronic device of claim 2 , wherein the processor is further configured to change a location of the second area of interest in accordance with the motion of the at least one object.

10. The electronic device of claim 2 , further comprising
a third camera,
wherein the processor is further configured to:
set a third area of interest for images to be captured using the third camera;
trace the motion of the at least one object in the second area of interest based on the motion of the at least one object in the set third area of interest; and
change the shooting speed of the first camera.

11. The electronic device of claim 2 , further comprising
a third camera,
wherein the processor is further configured to:
set a third area of interest for images to be captured using the third camera;
change the shooting speed of the first camera based on the motion of the at least one object in the set second area of interest;
change the shooting speed of the first camera based on the motion of the at least one object in the set third area of interest; and
provide control such that shooting based on the motion of the at least one object in the second area of interest and shooting based on the motion of the at least one object in the third area of interest are performed independently.

12. A method of an electronic device including a plurality of cameras including a first camera and a second camera, the method comprising:
setting a first area of interest for images to be captured using the first camera and a second area of interest for images to be captured using the second camera;
tracing a motion path of the at least one object in the second area of interest; and
performing high-speed shooting for image capture by changing a shooting speed of the first camera to a second frame rate greater than a first frame rate by comparing the motion path of the at least one object and the first area of interest based on a distance and a direction.

13. The method of claim 12 , further comprising:
changing a shooting speed of the first camera based on detecting a motion of the at least one object.

14. The method of claim 13 , further comprising determining a point in time for changing the shooting speed of the first camera by tracing the motion of the at least one object in the second area of interest.

15. The method of claim 13 , further comprising:
determining a point in time for changing the shooting speed of the first camera by comparing the motion path of the at least one object and the first area of interest based on a distance and a direction.

16. The method of claim 15 , wherein the shooting speed of the first camera changes at a point in time at which the at least one object is located within a distance less than a reference value from the first area of interest in accordance with the motion path.

17. The method of claim 13 , wherein the shooting speed of the first camera changes based on the motion of the at least one object.

18. The method of claim 13 , wherein a location of the second area of interest changes in accordance with the motion of the at least one object.

19. The method of claim 13 , wherein the electronic device further includes a third camera, and the method further comprises:
setting a third area of interest for images to be captured using the third camera;
tracing the motion of the at least object in the second area of interest based on the motion of the at least one object in the third area of interest; and
change the shooting speed of the first camera.

20. The method of claim 13 , wherein the electronic device further includes a third camera, and the method further comprises:
setting a third area of interest for images to be captured using the third camera;
changing the shooting speed of the first camera based on the motion of the at least one object in the second area of interest; and
changing the shooting speed of the first camera based on the motion of the at least one object in the third area of interest,
wherein shooting based on the motion of the at least one object in the second area of interest and shooting based on the motion of the at least one object in the third area of interest are performed independently.
