Abstract

A mobile terminal of controlling playback speed of an image by using a touch gesture and a method for controlling playback speed of a mobile terminal are provided. A direction, such as fast-forward or rewind, and a multiple velocity of a video screen image are determined according to a direction and movement distance of a touch gesture made by moving a user'"'"'s finger on a video reproduction screen image and the video screen image is moved according to the determined multiple velocity and direction at a corresponding position when the touch gesture is released such that the video can be fast-forwarded or rewound at various speeds.

Claims

1. A method of controlling a playback speed in a mobile terminal, the method comprising:

reproducing a video on a display;

detecting a touch gesture on the display;

determining a reproduction direction of the video according to a direction of the detected touch gesture;

determining a multiple velocity of the video according to a movement distance of the detected touch gesture; and

moving the reproduced video according to the determined reproduction direction and multiple velocity.

2. The method of claim 1, wherein the touch gesture comprises a touch and drag movement.

3. The method of claim 1, wherein moving the reproduced video comprises fast-forwarding when the detected touch gesture moves to the right and rewinding when the detected touch gesture moves to the left.

4. The method of claim 1, wherein the determined multiple velocity corresponds to the movement distance of the detected touch gesture and ranges from 0.5×

to 8×

.

5. The method of claim 1, further comprising displaying the determined multiple velocity on the display as a multiple velocity icon at an upper side of the detected touch gesture according to the movement distance of the detected touch gesture.

6. The method of claim 5, further comprising displaying the determined reproduction direction as an indicator at an upper side of the detected touch gesture according to the direction of the detected touch gesture.

7. The method of claim 1, further comprising:

displaying the determined reproduction direction and multiple velocity on the display while the detected touch gesture is maintained; and

moving the reproduced video according to the determined reproduction direction and multiple velocity at a corresponding position when the detected touch gesture is released.

8. The method of claim 7, wherein the determined reproduction direction and multiple velocity are displayed in proximity to the detected touch gesture.

9. The method of claim 7, further comprising displaying an increased multiple velocity on the display that corresponds to an increased movement distance when the touch gesture is dragged.

10. The method of claim 1, further comprising storing the determined multiple velocity as information in a table in a memory.

11. A mobile terminal comprising:

a display unit configured to display a reproduced video;

a sensing unit configured to detect a touch gesture on the displayed reproduced video; and

a controller configured to determine a reproduction direction of the video according to a direction of the detected touch gesture, determine a multiple velocity of the video according to movement distance of the detected touch gesture and to move the reproduced video according to the determined reproduction direction and multiple velocity.

12. The mobile terminal of claim 11, wherein the touch gesture comprises a touch-and-drag movement.

13. The mobile terminal of claim 11, wherein the controller is further configured to control the display unit to fast-forward the reproduced video when the detected touch gesture moves to the right and to rewind the reproduced video when the detected touch gesture moves to the left.

14. The mobile terminal of claim 11, wherein the determined multiple velocity corresponds to the movement distance of the detected touch gesture and ranges from 0.5×

to 8×

.

15. The method of claim 11, the controller is further configured to control the display unit to display the determined multiple velocity as a multiple velocity icon at an upper side of the detected touch gesture according to the movement distance of the detected touch gesture.

16. The method of claim 15, the controller is further configured to control the display unit to display the determined reproduction direction as an indicator at an upper side of the detected touch gesture according to the direction of the detected touch gesture.

17. The mobile terminal of claim 11, wherein the controller is further configured to:

control the display unit to display the determined reproduction direction and multiple velocity while the detected touch gesture is maintained; and

control the display unit to move the reproduced video according to the determined reproduction direction and multiple velocity at a corresponding position when the detected touch gesture is released.

18. The mobile terminal of claim 17, wherein the controller is further configured to control the display unit to display the determined reproduction direction and multiple velocity in proximity to the detected touch gesture.

19. The mobile terminal of claim 17, wherein the controller is further configured to control the display unit to display an increased multiple velocity that corresponds to an increased movement distance when the touch gesture is dragged.

20. The mobile terminal of claim 11, further comprising:

a memory configured to store the determined multiple velocity as information in a table, the information corresponding to the movement distance of the detected touch gesture.
