Abstract

An apparatus and a method for displaying an image in a mobile terminal are provided. More particularly, an apparatus and a method for rotating a displayed image in a direction and by an angle desired by a user through a simple touch input in a mobile terminal are provided. The apparatus includes an image rotator. The image rotator detects a user'"'"'s touch input while an image is displayed to determine a rotation direction and a rotation angle for the image, and rotating the displayed image in the determined rotation direction by the determined rotation angle.

Claims

1. An apparatus for rotating a displayed image in a mobile terminal, the apparatus comprising:

an image rotator for detecting a user'"'"'s touch input while an image is displayed to determine a rotation direction and a rotation angle for the image, and rotating the displayed image in the determined rotation direction by the determined rotation angle.

2. The apparatus of claim 1, wherein a position where the user'"'"'s touch input initially occurs is a rotation center point about which the image is rotated.

3. The apparatus of claim 1, wherein when detecting the user'"'"'s touch input while the image is displayed, the image rotator displays an image rotation menu, determines the rotation angle using a touch movement distance inside the image rotation menu, and determines the rotation direction using a touch movement direction inside the image rotation menu.

4. The apparatus of claim 3, wherein when detecting a touch input outside the image rotation menu, the image rotator moves a screen of the image that is being displayed.

5. The apparatus of claim 4, wherein the image rotation menu is expressible using a circular diagram comprising a plurality of blocks, and the rotation angle is marked at a center of the circular diagram.

6. The apparatus of claim 5, wherein the plurality of blocks serve as blocks for determining the rotation angle, and change the rotation angle depending on a distance of a touch input that moves along the blocks.

7. A method for rotating a displayed image in a mobile terminal, the method comprising:

detecting a user'"'"'s touch input while an image is displayed to determine a rotation direction and a rotation angle for the image; and

rotating the displayed image in the determined rotation direction by the determined rotation angle.

8. The method of claim 7, wherein a position where the user'"'"'s touch input initially occurs is a rotation center point about which the image is rotated.

9. The method of claim 7, wherein the detecting of the user'"'"'s touch input while the image is displayed comprises:

when detecting the user'"'"'s touch input while the image is displayed, displaying an image rotation menu;

determining the rotation angle using a touch movement distance inside the image rotation menu; and

determining the rotation direction using a touch movement direction inside the image rotation menu.

10. The method of claim 9, wherein the detecting of the user'"'"'s touch input while the image is displayed further comprises, when detecting a touch input outside the image rotation menu, moving a screen of the image that is being displayed.

11. The method of claim 10, wherein the image rotation menu is expressible using a circular diagram comprising a plurality of blocks, and the rotation angle is marked at a center of the circular diagram.

12. The method of claim 11, wherein the plurality of blocks serve as blocks for determining the rotation angle, and change the rotation angle depending on a distance of a touch input that moves along the blocks.

13. An apparatus for rotating a displayed image in a mobile terminal, the apparatus comprising:

a memory unit for storing information regarding a rotation direction and a rotation angle that depends on at last one of a movement and direction of a user'"'"'s touch input;

a display unit for displaying a rotated image according to the user'"'"'s touch input;

an input unit for detecting the user'"'"'s touch input for rotating an image;

an image rotator for determining a rotation direction and a rotation angle that depends on the user'"'"'s touch input; and

a controller for controlling to rotate the image displayed on the display unit in the rotation direction by the rotation angle determined by the image rotator.

14. The apparatus of claim 13, wherein a position where the user'"'"'s touch input initially occurs is a rotation center point about which the image is rotated.

15. The apparatus of claim 13, wherein when detecting the user'"'"'s touch input for rotating an image, the controller controls to display an image rotation menu.

16. The apparatus of claim 15, wherein the image rotator determines a touch input inside the image rotation menu to determine the rotation angle and the rotation direction.

17. The apparatus of claim 15, wherein the image rotation menu is expressible using a circular diagram comprising a plurality of blocks, and the rotation angle is marked at a center of the circular diagram.

18. The apparatus of claim 17, wherein the plurality of blocks serve as blocks for determining the rotation angle, and change the rotation angle depending on a distance of a touch input that moves along the blocks.
