When the touch of the object is detected on the display unit 151, the sensing unit 140 displays the object until the object is detached from the display unit 151, that is, Monitor (or track, monitor) the movement of objects.

That is, the first movement is a movement until the object is touched on the display unit 151 and the touch on the display unit 151 is terminated.

Here, the object may be a user's finger, an electrostatic touch pen, a stylus pen, or the like when the sensing unit 140 senses the electrostatic touch, and the sensing unit 140 senses the pressure sensitive touch The user's finger, the electrostatic touch pen, or the stylus pen may be various objects.

Meanwhile, the sensing unit 140 can monitor the rotation gesture only when the movement of the object is detected on the playback region 210 (see Fig. 4 (a)). In addition, Once the gesture is entered, it is also possible to monitor it.

Next, the control unit 180 (see FIG. 1) determines whether the first motion monitored in step S200 corresponds to the rotation gesture (S300).

That is, in the present invention, it is possible to receive a 'time adjustment command (or image search command)' for the moving image data through the rotation gesture.

Here, the 'time adjustment command' switches an image output from the playback area 210 (see FIG. 4A) to an image having time information different from that of the image, To be made.

Accordingly, when the first motion corresponding to the rotation gesture is detected, the controller 180 reproduces the image of the point corresponding to the rotation degree in the image output from the current reproduction area according to the rotation degree of the first motion The image output to the area can be switched.

For example, as shown in FIG. 4 (b), when the object 400 is rotated from the first point 310a to the second point 310b with a radius corresponding to the first image 310, Can be said to correspond to a 'rotation gesture'. Here, the size of the first image 310 is not limited, and it is possible to use a rotation gesture having various radii.

As described above, when the first motion corresponds to the rotation gesture, the controller 180 controls the first image outputted to the display unit 151 to be a second image different from the first image in response to the first motion (S400, see Fig. 3).

Here, the first image and the second image are images having different time information, i.e., corresponding to different times.

The control unit 180 extracts a rotation parameter including at least one of a rotation length, a rotation direction, a rotation radius, and a rotation speed of the first movement from the first movement.

The control unit 180 calculates time interval information using the extracted rotation parameters, and extracts a second image having a time interval corresponding to the first image and the calculated time interval information. Then, the extracted second image is output to the display unit 151.

That is, the moving image data is composed of a plurality of still images having time information, and the moving image is displayed as moving images (or moving images) by outputting still images continuously included in the moving image data in rapid succession.

The control unit 180 extracts the still image (or the second image) having the time information corresponding to the first motion on the plurality of still images included in the moving image data, extracts the extracted still image (or the second image) Can be output to the display unit 151.

Also, in order to convert the image outputted to the display unit into another image, extracting the image corresponding to the rotation gesture can be expressed as 'searching' the 'still image' included in the moving image data.

That is, the user uses the rotation gesture to search for an image of a desired part of the user, and when the image of the desired part is searched, it is intended to output it to the display unit.

Also, in this manner, in response to the first motion corresponding to the rotation gesture, the time information of the searched image can be changed according to the values of the extracted rotation parameters.

For example, according to the size of the 'rotation radius' of the rotation gesture, the size of the time interval between the reference image (the image currently output from the display unit) can be made different even if the movement length of the object is the same. As an example, for an object having a large turning radius, an image can be searched while having a time interval smaller than the time interval of movement of an object having a small turning radius.

Further, the size of the time interval between the reference image (the image currently being output from the display unit) can be made different according to the " rotation length ". As an example, it is possible to search for images having a time interval longer than the time interval of the 'short motion' for the rotation length 'long motion'.

Also, according to the " rotation direction ", it is possible to search for an image before or after the time of the reference image.

The criteria for such rotation parameters may be preset, for example, if the object is moved by '0.1 cm', it is set to extract an image having a time interval of '3 seconds' .

In this way, the control unit 180 applies the values of the rotation parameters to the preset reference, and displays the image having the time information corresponding to the time apart from the image output to the display unit 151 by the time interval corresponding to the rotation parameter .

For example, as shown in FIG. 4 (b), the control unit 180 may control movement of the object 400 from the first point 310a to the second point 310b, corresponding to the rotation gesture, In the first image 210a shown in FIG. 4 (a), a second image 210b corresponding to the second point 310b is output.

4C, in response to the subsequent movement (310a - > 310b - > 310c) of the object 400, the control unit 180 controls the third And outputs the image 210c.

When the touch of the object 400 with respect to the display unit 151 is terminated, the control unit 180 can reproduce the image again from the switched third image 210c.

When the first motion of the object is sensed, the control unit 180 continues the image being reproduced in the display unit 151 before the first motion is sensed on the display unit 151, And when the touch of the object is terminated, an image corresponding to the first motion can be output.

In addition, the control unit 180 may continuously output an image of a point corresponding to the first motion on the display unit 151 in conjunction with the first motion.

In this manner, the controller 180 can search for an image corresponding to the moving image data in response to the movement of the object corresponding to the rotation gesture.

In addition, since the rotation gesture has no limitation on the length and the image can be searched only when the object is rotated, even if the time interval of the searched image is finely set, It is possible to search.

That is, when moving image data having a long time length is searched, it is possible to search for an image seamlessly using the rotation of the object.

Therefore, even if the image is set to be searched at intervals of '1' second with respect to the movement of the object of '1 cm' in the moving image data having the length of 10 minutes, since the image is searched only if the object is rotated, It is possible to search for an image seamlessly with a single touch.

In the above, a method of searching an object using a rotation gesture has been described.

Hereinafter, a method of searching for different images according to a rotation parameter value corresponding to a rotation gesture will be described.

FIGS. 5 and 6 are conceptual diagrams for explaining a method of searching for an image according to a rotation parameter value in a mobile terminal according to an embodiment disclosed herein; FIG. 7 is a flowchart illustrating a method of searching for a moving image according to an embodiment of the present invention, Fig. 8 is a conceptual diagram for explaining a method of displaying a guide image according to a turning radius. Fig.

5, the controller 180 controls the display unit 151 in accordance with the rotation direction of an object (e.g., a finger) touched on the display unit 151, .

When the movement corresponding to the rotation gesture of the object is monitored in the playback area 210, the controller 180 determines the rotation direction of the movement of the object. Then, the image is searched in the direction set in the clockwise direction or counterclockwise direction. That is, the clockwise rotation may be set to search for an image behind the currently output image, and the counterclockwise rotation may be set to search for an image that is ahead of the currently output image.

For example, when the object is rotated clockwise from the first point 310a to the second point 310b, as shown in FIG. 5A, The second image 210b behind the time information "3 minutes 45 seconds"

Accordingly, the second image 210b corresponding to the second point 310b and corresponding to "4 minutes 05 seconds " behind the time of the first image 210a is output to the display unit 151. [

5 (b), when the object is rotated counterclockwise from the first point 310a to the second point 310b, the control unit 180 determines whether the first image 310a The second image 210b preceding the time information "3 minutes 45 seconds"

Accordingly, the second image 210b corresponding to the second point 310b and corresponding to "2 minutes and 10 seconds" preceding the time of the first image 210a is output to the display unit 151. [

Next, a method of outputting an image having different time information according to the rotation radius will be described with reference to FIG.

The control unit 180 can search for an image having a different time interval from the reference image (the image currently being output from the display unit) even if the motion length of the object is the same, according to the size of the 'turning radius' of the rotation gesture of the object have.

That is, the control unit 180 may set time intervals of images to be searched for at different rotation radii differently from each other.

For example, for a rotation with a large turning radius, an image may be set to be searched at a time interval of 3 seconds for a motion of an object of "0.1 cm ". For a rotation with a small turning radius, it is possible to set an image to be searched at intervals of 10 seconds with respect to movement of an object of "0.1 cm ".

As shown in Fig. 6 (a), the turning radius in Fig. 6 (a) is larger than the turning radius in Fig. 6 (b).

6 (a), the control unit displays, for the motion of the object from the first point 310a to the second point 310b, the motion of the object corresponding to "3 minutes 45 seconds" 1 image 210a and a second image 210b corresponding to "3 minutes and 50 seconds" having a time interval of '5' seconds.

On the other hand, as shown in Fig. 6 (b), the control unit 180 moves from the first point 310a having the turning radius smaller than the turning radius in Fig. 6 (a) to the second point 310b The first image 210a corresponding to "3 minutes 45 seconds" outputted to the display unit and the second image 210b corresponding to "5 minutes and 30 seconds" ).

Also, contrary to the above, it is also possible to search an image with a larger time interval for a larger radius of rotation, and with a smaller time interval for a smaller radius of rotation.

7A, the controller 180 may display guide images 320a and 320b on the display unit 151 corresponding to different rotation radii. In addition, search information having the radius of rotation can be displayed in an area adjacent to the guide images 320a and 320b.

For example, the first turning radius 320a having a radius larger than the second turning radius 320b searches the image at 2x speed and the second turning radius 320b searches the image at 3x speed (3x) . The control unit 180 may display search speed information corresponding to each of the rotation radii on the display unit 151 to provide search information to the user.

The guide images 320a and 320b may be output based on the user's selection and may be set to be automatically output when an object is touched on the display unit 151. [

On the other hand, the control unit 180 can move to different search conditions by switching the turning radius while searching for an image.

For example, as shown in FIG. 7 (b), when an object is touched with a rotation radius corresponding to double speed on the display unit 151, Horizontal movement), the control unit 180 can change the turning radius for this movement.

In this case, the control unit 180 can display information about the rotated radius 310a corresponding to the horizontal movement of the object, in addition to the rotation radius corresponding to the conventional double speed.

That is, the control unit 180 displays a plurality of guide images (or dial images) having different radii on the display unit 151. Such a plurality of dial images are matched with different time interval information. When the motion of the object is monitored in any one of the plurality of dial images, the control unit 180 extracts the image from the moving image data corresponding to the time interval information matched to any one of the dial images.

Further, in addition to the above-mentioned change of the turning radius, it is possible to flexibly change, corresponding to the subsequent rotation gesture of the object. That is, if the object rotates with a large radius and rotates with a small radius, the search condition can be set to be different.

In the above, a method of searching an image under different conditions according to the value of the rotation parameter has been described.

Hereinafter, an entry process for searching for an image will be described.

FIG. 8 is a conceptual diagram illustrating an entry process for searching for an image in a mobile terminal according to an embodiment disclosed herein.

The sensing unit 140 (see FIG. 1) may execute monitoring of the movement of the object based on whether the object is touched on the display unit 151, or based on selection by the user.

That is, in the control unit 180, an entry process for generating a 'time adjustment command' for searching for an image included in moving image data for a first motion corresponding to a rotation gesture of an object touched on the display unit 151 is various . ≪ / RTI >

For example, as shown in Fig. 8A, the touch of the object is started at the first point 220a of the slide bar 220a, and at the first point 220a, The controller 220 may control the sensing unit 140 to monitor the rotation gesture of the object when the object is dragged to the second point 220b.

8 (b), when the object 230 is touched on the display unit 151 in a predetermined manner, the control unit 180 displays a 'time adjustment command (or image search command)', Can be activated. Accordingly, if a predetermined type of touch is input on the display unit 151 and then the movement of the object corresponding to the rotation gesture is detected on the display unit 151, The image can be extracted.

As shown in FIG. 8 (c), a time adjustment command (or an image search command, image switching command) can be activated through a separate icon 240.

Accordingly, when the icon 240 is selected by the user and the movement of the object corresponding to the rotation gesture is detected on the display unit 151, the controller 180 can extract the image corresponding to the movement of the object have.

Meanwhile, the sensing unit 140 may monitor the movement of the object corresponding to the rotation gesture in an arbitrary region on the display unit 151, but may monitor the movement of the object only in a predetermined region.

That is, the display unit 151 may include a rotation area for monitoring movement corresponding to the rotation gesture of the object.

In this case, the sensing unit 140 monitors the movement of the object when the object is sensed on the rotation area. In addition, the control unit 180 switches the image output to the display unit 151 in response to the movement corresponding to the rotation gesture of the object with respect to the rotation region.

8 (d), when the 'time adjustment command' is activated, the control unit 180 displays the guide image 320 for the rotation area on the display unit 151, Can provide information about the rotation area.

In addition, the mobile terminal according to the present invention can display an image reproduced in the reproduction area without stopping and search for moving image data by displaying an image corresponding to the motion of the object in an area separate from the reproduction area.

9 and 10 are conceptual diagrams illustrating a preview area in a mobile terminal according to an embodiment disclosed herein.

9 (a), when the object is touched on the display unit 151 and the movement of the object (e.g., finger) corresponds to the rotation gesture 310, And searches for an image at a time point corresponding to the motion of the user.

Then, as shown in FIG. 9B, a preview area 260 is generated which is distinguished from the playback area 210, and images 261, 262, and 263 corresponding to the motion of the object are output.

In this case, the control unit 180 may output only the image corresponding to the end point of the motion of the object to the preview area 260, Images can be extracted and output.

That is, the control unit 180 determines, based on a predetermined time interval, among a plurality of images included between the viewpoint of the image output to the display unit 151 and the viewpoint at which the movement of the object is stopped, , And extracts the image.

Here, 'motion end point' does not mean that the touch of the object is released, but the point where the motion of the object is stopped.

Thus, when the object moves from "3 minutes 45 seconds" to "4 minutes 15 seconds" as shown in FIG. 9 (b), the control unit 180 displays the images 261, 262 , And 263 can be extracted and output to the preview area 260.

In addition, the control unit 180 causes the video reproduced in the reproduction area 210 to be continuously reproduced without stopping the motion of the object,

When one of the images 261, 262, and 263 output to the preview area is selected by the user as shown in FIG. 9C, as shown in FIG. 9D, And outputs the image selected by the user to the taching area 210.

Then, the control unit 180 controls the moving image to be reproduced from the time point corresponding to the selected image.

In this case, the preview area 260 can be made to disappear based on the selection of any one of the images in the preview area 260. [

In addition, when the preview area 260 is created, the size of the playback area 210 can be changed in association with the generation of the preview area 260.

As described above, in the mobile terminal according to the present invention, it is possible to search for an image without stopping the reproduced image, and the user can conveniently search and view the image by previewing the searched image.

In addition, the controller 180 may set the number of images output to the preview area, that is, the number of images to be extracted, differently according to the motion speed of the object.

Referring to FIG. 10, it is assumed that the rotational speed in FIG. 10 (a) is larger than that in FIG. 10 (b).

10A and 10B, when the object moves from the first point 311a to the second point 311b by a distance corresponding to '15' second intervals at different speeds,

In FIG. 10 (a), in which the rotational speed is larger, three images 261, 262 and 263 are extracted and five images 261, 262, 263, 264, 265 are extracted.

That is, the control unit 180 extracts the number of images differently according to the motion speed of the object by grasping the user's intention to search the image quickly or slowly through the rotation speed of the motion.

As described above, according to an embodiment of the present invention, a mobile terminal and a control method thereof include receiving a time adjustment command for moving image data using a rotation of an object touched on a display unit, Since they are not constrained, images can be matched at fine time intervals. Therefore, in response to the time adjustment command, it is possible to fine tune the image conversion to the moving image data.

In addition, the mobile terminal and the control method thereof according to an embodiment of the present invention set the time interval of the image corresponding to the time adjustment command differently according to the rotation speed and the rotation radius of the object touched on the display unit, The image can be controlled at various time intervals.

In addition, the mobile terminal and its control method according to an embodiment of the present invention may output a video corresponding to the preview time adjustment command in the preview area without stopping the currently reproduced video in response to the video switching command, The reproduced image can be continuously reproduced without being stopped.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
