Method for providing screen magnification and electronic device thereof

1. A method for providing screen magnification in an electronic device, the method comprising:

displaying a screen;

detecting a screen magnification event;

determining a target area on the screen based on the screen magnification event;

displaying the target area on a display area on a certain location of the screen;

changing a size of the display area based on a gesture on the display area; and

changing a magnification ratio of the target area according to the size of the display area.

2. The method of claim 1 , wherein the screen magnification event is detected by a hovering input.

3. The method of claim 2 , wherein the determining of the target area comprises determining the target area based on coordinates of the hovering input on the screen.

4. The method of claim 2 , wherein the magnifying of the target area comprises:

determining the magnification ratio of the target area based on a height of the hovering input from the screen; and

adjusting the target area according to the magnification ratio.

5. The method of claim 4 , further comprising changing, when the height of the hovering input from the screen is changed, the magnification ratio of the target area.

6. The method of claim 2 , further comprising:

detecting a change in coordinates of the hovering input on the screen;

disregarding, when the change in the coordinates is less than or equal to a reference value, the change in the coordinates; and

moving, when the change in the coordinates exceeds the reference value, the target area on the screen according to the change in the coordinates.

7. The method of claim 1 , wherein the detecting of the screen magnification event comprises:

displaying a virtual input pad on the screen; and

detecting the screen magnification event on the virtual input pad.

8. The method of claim 1 , wherein the determining of the target area comprises determining the target area in a circular shape, an oval shape, a polygonal shape, or a water drop shape.

9. The method of claim 1 , wherein the magnifying of the target area comprises applying a water drop effect or a magnifying glass effect to the target area.

10. An electronic device comprising:

a display; and

a processor configured to:

display a screen on the display,

detect a screen magnification event,

determine a target area on the screen based on the screen magnification event,

display the target area on a display area on a certain location of the screen,

change a size of the display area based on a gesture on the display area, and

change a magnification ratio of the target area according to the size of the display area.

11. The electronic device of claim 10 , further comprising:

a sensor configured to detect a hovering input on the display,

wherein the processor is further configured to detect the hovering input as the screen magnification event.

12. The electronic device of claim 11 , wherein the processor is further configured to determine the target area based on coordinates of the hovering input on the screen.

13. The electronic device of claim 11 , wherein the processor is further configured to:

determine the magnification ratio of the target area based on a height of the hovering input from the screen, and

adjust the target area according to the magnification ratio.

14. The electronic device of claim 13 , wherein, when the height of the hovering input from the screen is changed, the processor is further configured to change the magnification ratio of the target area.

15. The electronic device of claim 11 , wherein the processor is further configured to:

detect a change in coordinates of the hovering input on the screen,

disregard, when the change in the coordinates is less than or equal to a reference value, the change in the coordinates, and

move, when the change in the coordinates exceeds the reference value, the target area on the screen according to the change in the coordinates.

16. The electronic device of claim 10 , wherein the processor is further configured to:

display a virtual input pad on the screen, and

detect the screen magnification event on the virtual input pad.

17. The electronic device of claim 10 , wherein the processor is further configured to apply a water drop effect or a magnifying glass effect to the target area.

18. 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 .
