Hereinafter, embodiments of the present invention will be described.

The control method of the mobile terminal 100 according to an embodiment of the present invention may be performed by the mobile terminal 100 described with reference to FIG. 1.

2 is a flowchart illustrating a control method of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 2, the controller 180 reads and plays a video selected by a user from the memory 160. In addition, the playback screen of the selected video is displayed on the touch screen 151 (S101).

In addition, the controller 180 displays at least one item corresponding to a frame moving function on the touch screen 151 based on a user's control input (S102).

Here, the frame shift function includes a rewind (REWind, REW), a fast forward (FF) function, and the like. When the frame move function is executed, the controller 180 moves to the previous frame or the next frame instead of the frame currently being played.

Items corresponding to the frame movement function may be displayed in various forms such as buttons and jogs.

3 and 4 illustrate examples of displaying an item to which a frame moving function corresponds.

Referring to FIG. 3, the controller 180 displays a playback screen of the selected video on the touch screen 151.

In addition, the controller 180 displays a progress bar 3a indicating a playback state of the video currently being played on the touch screen 151, and displays the current playback position of the video on the progress bar 3a. The indicating indicator 3b is displayed. The current playback position of the video indicates the frame currently displayed on the playback screen.

In addition, the controller 180 displays the buttons 3c and 3d corresponding to the frame moving function on the touch screen 151. Each of the buttons 3c and 3d is associated with a rewind function for moving the playback position to the previous frame and a fast forward function for moving the playback position to the next frame.

According to an embodiment of the present disclosure, the user may move the playback position of the video not only by touching the buttons 3c and 3d but also by dragging.

For example, when each button 3c or 3d is pressed, the controller 180 may move the frame forward or backward by the number of touches or the touch holding time to display the frame.

For example, when dragging each button 3c or 3d, the controller 180 continuously moves the frame until the touch on each button 3c or 3d is released, and each button 3c, Depending on the drag distance of 3d), the frame movement speed may be varied.

Referring to FIG. 4, the controller 180 may display a jog wheel 3e on the touch screen 151 for moving a playback position of a video to a previous / next frame.

According to an embodiment of the present disclosure, the user may move the frame in a desired direction by dragging the jog wheel 3e.

Referring back to FIG. 2, when the item corresponding to the frame moving function is dragged by the user (S103), the controller 180 calculates a frame moving speed according to the distance from which the item is dragged (S104). In addition, based on the calculated frame moving speed, the playback position is moved to the previous / next frame (S105).

In step S104, the controller 180 increases / decreases the frame moving speed according to the drag distance of the item to which the frame moving function corresponds. The frame movement speed represents the speed of rewinding or fast forwarding the playback position.

The distance to which the item is dragged may be calculated differently according to the display form of the item.

For example, when the item is displayed in the form of a button, the controller 180 may obtain the distance between the original display position of the button and the position where the item is moved by dragging as the distance at which the item is dragged.

Also, for example, when the item is displayed in the form of a jog wheel, the controller 180 may obtain the distance in which the jog wheel is rotated by the drag operation as the drag distance.

5 and 6 illustrate examples of controlling the frame movement speed according to the dragged distance.

5 (a) and 5 (b) show how the moving speed of the frame changes according to the distance of dragging the button 3c to which the rewinding function corresponds.

Referring to FIGS. 5A and 5B, the controller 180 obtains dragged distances d1 and d2 as the rewind button 3c is touched by the user and dragged in a specific direction. Further, the rewind speed is calculated in accordance with the drag distances d1 and d2 of the button 3c.

Referring to FIGS. 5A and 5B, the distance to which the rewind button 3c is dragged is longer in FIG. 5B than in FIG. 5A. Accordingly, it can be seen that in FIG. 5B, the rewind speed is increased than in FIG. 5A.

The controller 180 may display the progress bar 5a indicating the rewind speed on the touch screen 151 so that the user can intuitively grasp the rewind speed calculated according to the drag distances d1 and d2. Can be. Accordingly, the user may intuitively grasp the rewind speed that is changed according to the drag distance d1 of the rewind button 3c, and move the rewind button 3c to the desired rewind speed based on this.

6 (a) and 6 (b) show how the moving speed of the frame changes according to the distance of dragging the jog wheel 3e to which the frame moving function corresponds.

Referring to FIGS. 6A and 6B, as the jog wheel 3e is touched by the user and dragged in the left direction, the controller 180 executes a rewind function. Furthermore, the distance which the jog wheel 3e rotated by dragging is acquired, and a rewind speed is calculated according to the rotation degree of the jog wheel 3e.

Referring to FIGS. 6A and 6B, the degree of rotation of the jog wheel 3e is larger in FIG. 6B than in FIG. 6A. Accordingly, in FIG. 6B, the rewind speed is increased as in FIG. 6A.

Referring back to FIG. 2, in step S105, the moving direction of the frame may be determined by the direction in which the item is dragged.

For example, if the item is displayed in the form of a button and a button corresponding to the rewind function is dragged by the user, the controller 180 may perform a rewind function or a fast forward function according to the drag direction. That is, when the button corresponding to the rewind function is dragged to the left, the controller 180 executes a rewind function to move the playback position to the previous frame, and when the button corresponding to the rewind function is dragged to the right, Even if the button is a rewind button, you can also execute the fast-forward function, which moves the playback position to the next frame.

For example, when the item is displayed in the form of a jog wheel, the controller 180 may execute a rewind function when the jog wheel rotates to the left by dragging, and execute a fast forward function when the jog wheel rotates to the right. have.

Referring again to FIG. 2, when the touch on the item to which the frame moving function is corresponding is not released, the controller 180 determines that the frame moving speed calculated according to the distance dragged from the item is less than or equal to the preset speed (S106). In step S107, a predetermined section enlarged based on the current playback position is displayed on the progress bar.

In addition, when a specific position is touched in the enlarged progress bar, the playback position is shifted to a frame corresponding to the touched position (S108).

In steps S106 and S107, the controller 180 enlarges and displays a progress bar when the frame moving speed calculated in step S104 is less than or equal to a preset speed, for example, a normal playback speed.

In step S107, the controller 180 may enlarge and display the progress bar currently being displayed, or separately display the enlarged progress bar.

7 and 8 illustrate examples of magnifying and displaying a progress bar.

Referring to FIG. 7, as shown in FIG. 7A, the controller 180 maintains the normal playback speed 1x for more than a preset time while the frame movement speed is touched. In the bar 7a, a predetermined section is selected based on the current playback position.

In addition, as shown in FIG. 7B, instead of the progress bar 7a representing the entire playback section 7b, the progress bar 7c representing only the selected playback section 7d is applied to the touch screen 151. Display.

Referring to FIG. 8, unlike FIG. 7B, the controller 180 displays a progress bar 7a representing the entire playback section 7b and a progress bar 7c representing only the selected playback section 7d. Mark together.

Meanwhile, referring to FIG. 8, the controller 180 may display the indicators 8a and 8b indicating where the selected playback section is located among the entire playback sections so that the user can intuitively determine where the selected section is. It may be displayed on the progress bar 7a indicating the reproduction section.

9 shows an example of moving the frame using the progress bar enlarged in step S108.

Referring to FIG. 9, as shown in FIG. 9A, the controller 180 displays a progress bar 7c in which only a predetermined section of all playback sections is enlarged on a video playback screen, and the progress bar is displayed. As a specific position on 7c is touched, a frame corresponding to the touched position is selected.

In addition, as shown in Fig. 9B, the playback position 9a is changed to the selected frame. That is, it moves to the selected frame.

In FIG. 9, when the frame movement is performed as a specific point is touched in the progress bar 7c which enlarges only a predetermined section, the progress bar 7c automatically disappears from the screen. Make it clear that it is not limited. According to the present invention, even if a frame movement occurs as a specific point is touched in the progress bar 7c in which only a predetermined section is enlarged, the display of the progress bar 7c may be maintained.

Meanwhile, according to an embodiment of the present disclosure, the controller 180 may change the frame moving direction while moving the frame in a specific direction by dragging an item to which the frame moving function corresponds.

10 illustrates an example of changing a frame moving direction.

Referring to FIG. 10, as shown in FIG. 10A, the controller 180 performs a rewind function of moving to a previous frame by dragging a button 3c corresponding to a rewind function to the left. .

Thereafter, the controller 180 moves to the next frame instead of the rewind function by dragging the rewind button 3c to the right while maintaining the touch of the rewind button 3c, as shown in FIG. To perform the fast forward function.

As shown in FIG. 10, when the user moves to the previous frame by using the rewind button 3c and moves earlier than the desired frame, the user moves the next frame by simply changing the drag direction of the rewind button 3c. You can change the direction of movement.

According to one embodiment of the present invention described above, the user can easily change the frame moving speed. That is, the user can increase the frame moving speed a little more if the user needs to move a large number of frames with a simple dragging operation, and lower the frame moving speed when the user needs to move to a frame close to the current frame.

In addition, it is possible to change the frame movement direction only by changing the drag direction, so that the user can easily manipulate the frame to return to the desired frame even if the user passes the desired frame.

In addition, by enlarging and displaying a predetermined section of the progress bar, the user can perform a more detailed operation.
