3. The imaging apparatus of claim 2 , further comprising an elastic member comprising an elastic material and coupled to each of the frame and the guide.

4. The imaging apparatus of claim 3 , wherein the elastic member comprises a torsion spring having a coil shape.

5. The imaging apparatus of claim 3 , wherein a protrusion protrudes from an outer circumferential surface of the guide, and

wherein the elastic member is caught by the protrusion.

6. The imaging apparatus of claim 1 , wherein the guide further comprises:

a guide contact coupled to an outer surface of the guide body to protrude outward and contacting the frame.

7. The imaging apparatus of claim 6 , wherein the guide further comprises a guide well coupled to an outer surface of the base.

8. The imaging apparatus of claim 6 , further comprising a support located between the base and the frame, and contacting the base and the frame.

9. The imaging apparatus of claim 8 , wherein the support comprises:

a support plate located between the base and the frame; and

a bearing provided on the support plate and contacting the base and the frame.

10. The imaging apparatus of claim 9 , wherein the bearing comprises a ball bearing.

11. The imaging apparatus of claim 10 , wherein one side of the bearing is in point contact with a surface of the base, and the other side of the bearing is in point contact with a surface of the frame.

12. The imaging apparatus of claim 1 , further comprising a support located between the guide and the frame and contacting the guide and the frame.

13. The imaging apparatus of claim 12 , wherein the support comprises:

a support plate located between the guide and the frame; and

a bearing provided on the support plate, and

wherein one side of the bearing is in point contact with a surface of the guide, and the other side of the bearing is in point contact with a surface of the frame.

14. The imaging apparatus of claim 1 , wherein the at least one camera comprises a plurality of cameras,

wherein the cameras are attached to the frame to be directed to different directions,

wherein the base of each of the cameras is rotatable within a corresponding preset angle, and in response to the base rotating, the lens of the each of the cameras is configured to rotate to change a photographing mode between different modes, and

wherein the different modes have different aspect ratios with regard to the sensor.

15. An imaging apparatus comprising:

a frame; and

at least one camera provided on the frame,

wherein each of the at least one camera comprises:

a lens;

a sensor coupled to the lens and configured to obtain an image;

a base coupled to the sensor or the lens, configured to receive external power, and rotatable on the frame; and

a guide connected to the base to be rotatable along with the base, and contacting the frame,

wherein the base is rotatable within a preset angle, and in response to the base rotating, the sensor and the lens are configured to rotate to change a photographing mode between a plurality of different modes, and

wherein the different modes comprise a first mode, in which a horizontal length of the image is greater than a vertical length of the image, and a second mode in which the horizontal length of the image is smaller than the vertical length of the image.

16. An imaging apparatus comprising:

a frame; and

at least one camera provided on the frame,

wherein each of the at least one camera comprises:

a lens;

a sensor coupled to the lens and configured to obtain an image; and

a base to which the sensor or the lens is coupled, and

wherein the base is configured to rotate on the frame by a preset angle to change a photographing mode between a plurality of different modes in which an aspect ratio of the sensor is different.

17. The imaging apparatus of claim 16 , wherein the frame comprises at least one frame stopper formed thereon configured to control rotation of the base by the preset angle.

18. The imaging apparatus of claim 16 , further comprising:

a guide engaged with the base and contacting the frame; and

an elastic member coupled to the frame and the guide to control the rotation of the base by the preset angle.

19. The imaging apparatus of claim 18 , further comprising at least one bearing located between the guide and the frame and contacting the guide and the frame.

20. The imaging apparatus of claim 16 , wherein the at least one camera comprises a plurality of cameras configured to capture a plurality of images, respectively using respective lenses, comprising the lens, and respective sensors comprising the sensor, and

wherein the images captured by the respective sensors form a panoramic image.
