4. The monitoring device of claim 2 , wherein the processor is further configured to:

detect a touch-and-hold input on an area surrounded by the portion of a ring shape, and

control the display to display a window for setting color and transparency of the panning control icon in response to detecting the touch-and-hold input.

5. The monitoring device of claim 1 , wherein the panning control icon further includes at least one guideline which indicates a reference panning direction.

6. The monitoring device of claim 1 , wherein the processor is further configured to:

in response to detecting a flick input on the panning control icon, control the panning control icon to disappear in accordance with the flick input.

7. The monitoring device of claim 1 , wherein the processor is further configured to:

detect a pinch input in a vicinity of the panning control icon, and

reduce a size of the panning control icon if the pinch input is a pinch-in input, and enlarge the size of the panning control icon if the pinch input is a pinch-out input.

8. The monitoring device of claim 2 , wherein the processor is further configured to:

control the display to display a tilting control icon for controlling tilting of the image, wherein the tilting control icon includes a first icon displayed near the direction marker and a second icon displayed in an opposite direction about a center of the ring shape,

in response to detecting an input of selecting the first icon, reduce a size of the first icon and enlarge a size of the second icon, and

in response to detecting an input of selecting the second icon, enlarge the size of the first icon and reduce the size of the second icon.

9. The monitoring device of claim 8 , wherein the processor is further configured to tilt the image downward in response to detecting an input of dragging the tilting control icon toward the first icon from the second icon, and tilt the image upward in response to detecting an input of dragging the tilting control icon toward the second icon from the first icon.

10. The monitoring device of claim 1 , further comprising a gyro sensor, wherein the processor is further configured to tilt the image based on a sensing value measured by the gyro sensor.

11. The monitoring device of claim 2 , wherein the processor is further configured to:

detect a drag input on an area surrounded by the ring shape, and

tilt the image in accordance with a dragging direction of the drag input.

12. The monitoring device of claim 2 , wherein the processor is further configured to:

detect a tap input or a double-tap input from an area that is not adjacent to the panning control icon, and

zoom in on the image in response to detecting the tap input, and zoom out on the image in response to detecting the double-tap input.

13. A monitoring method performed by a monitoring apparatus, the method comprising:

displaying an image acquired by a camera on a display of the monitoring apparatus;

displaying a panning control icon including an area corresponding to a panning range of the image and a direction of the camera on the display;

detecting an input of selecting one point from the area of the panning control icon;

determining a target panning direction based on a position of the selected one point on the panning control icon;

panning the image in the target panning direction;

displaying a direction marker at the position of the selected one point; and

changing a position of the panning control icon in response to detecting a drag-and-drop input on the panning control icon.

14. The monitoring method of claim 13 , wherein the displaying of the panning control icon on the display includes:

displaying a starting icon on a boundary area of the image;

detecting a drag-and-drop input on the starting icon; and

displaying the panning control icon on a point at which the starting icon is dropped according to the drag-and-drop input.

15. The monitoring method of claim 13 , wherein:

the panning control icon includes a portion of a ring shape,

the panning control icon is a closed ring shape when the panning range of the image is 360°, and is a ring shape having an opening when the panning range of the image is less than 360°, and

the opening represents an angle range in which panning is not available on the image.

16. The monitoring method of claim 15 , further comprising:

displaying a tilting control icon for controlling tilting of the image, wherein the tilting control icon includes a first icon displayed near the direction marker and a second icon displayed in an opposite direction about a center of the ring shape;

tilting the image downward when an input of selecting the first icon of the tilting control icon is detected; and

tilting the image upward when an input of selecting the second icon of the tilting control icon is detected.

17. A monitoring system comprising:

a camera configured to acquire an image; and

a monitoring device configured to display the image acquired by the camera,

wherein the monitoring device includes:

a transceiver configured to receive the image from the camera;

a memory configured to store the image;

a display configured to display the image; and

a processor configured to:

control the display to display a panning control icon including an area corresponding to a panning range of the image and a direction of the camera,

detect an input of selecting one point from the area of the panning control icon,

determine a target panning direction based on a position of the selected one point on the panning control icon,

perform panning on the image in the target panning direction,

display a direction marker at the position of the selected one point, and

change a position of the panning control icon in response to detecting a drag-and-drop input on the panning control icon.

18. The monitoring system of claim 17 , wherein:

the panning control icon includes a portion of a ring shape,

the panning control icon is a closed ring shape when the panning range of the image is 360°, and is a ring shape having an opening when the panning range of the image is less than 360°, and

the opening represents an angle range in which panning is not available on the image.

19. The monitoring system of claim 18 , wherein the processor is further configured to:

control the display to display a tilting control icon for controlling tilting of the image, wherein the tilting control icon includes a first icon displayed near the direction marker and a second icon displayed in an opposite direction about a center of the ring shape,

tilt the image downward when an input of selecting the first icon is detected, and

tilt the image upward when an input of selecting the second icon is detected.
