[Description of FIG. 5 - Flowchart]

5 is a flowchart illustrating an image editing method of a mobile terminal according to an exemplary embodiment of the present invention.

For convenience of description, it is assumed that the mobile terminal described below includes at least one of the components shown in FIG.

First, the mobile terminal 100 may store the image to be subjected to the image editing in the memory 160 prior to the image editing according to the present invention.

In particular, the mobile terminal 100 stores at least one frame in the memory 160 in units of storage areas in which a storage capacity of a predetermined time is set (S501).

The entire storage area of the memory 160 may be divided and managed in units of storage areas each having a storage capacity of a predetermined time. For example, assuming that the total storage area is "30 minutes" and the storage area of the storage area is "1 minute ", the entire storage area can be divided into 30 storage areas. The storage capacity and the number of storage areas may be set at the terminal production stage, or may be set or changed by the user.

Further, in each storage area, identification information for identifying the storage area can be set. In particular, the identification information may include the order information specified for each storage area. Therefore, frames can be sequentially stored in a plurality of storage areas according to the order information specified in each of the plurality of storage areas. For example, assuming that a frame transmission rate is 15 frames / second, a storage area capacity is 1 second, and a storage area number is 15, 15 frames can be stored in one storage area, 15 frames can be sequentially stored in each of the 15 storage areas.

In the storage step S501, when a storage command for a moving image input through the camera 121 is input, when a recording command for a broadcast signal received through the broadcast receiving module 111 is inputted, the wireless communication module 110, or received from a foreign terminal.

In particular, the user input unit 130 may receive a user operation corresponding to a broadcast recording command while the broadcast signal received through the broadcast receiving module 111 is output using the output unit 150. The control unit 180 sets a broadcast recording mode according to a user operation corresponding to a broadcast recording command and sequentially stores the frames constituting the video signal of the received broadcast signal in the storage areas described above. On the other hand, if the recording reservation is set, the control unit 180 may set a broadcast recording mode at the scheduled recording execution time, and sequentially store the frames constituting the video signal of the broadcast signal to be recorded in each storage area.

Also, one or more representative frames may exist in one storage area. More specifically, one storage area may contain one or more transport stream packets (hereinafter referred to as 'TS packets'), and the first frame of the transport stream packet located at the front of a specific storage area may be a representative frame have. For example, the representative frame may include an infra-frame (hereinafter " I-frame "). Here, the I-frame is intra-coded as a reference frame for motion prediction / compensation at the time of compressing or restoring the video image, and thus can restore itself. In particular, in mobile broadcasting, there may be more than one I-frame per second for fast recovery in the event of a transmission error.

Hereinafter, the PS packets stored by the storage area and the storage area will be described with reference to FIGS. 6A to 6C. As described above, the storage capacity of the storage area can be set in units of time.

As shown in FIG. 6A, the entire storage area T_total is divided into N storage areas T_sector and managed, and a plurality of frames may be stored in each storage area. Also, in each storage area, order information, for example, Time Sector_0, Time Sector_1, Time Sector_2, ..., Time Sector_ (N-1) may be set.

As shown in FIG. 6B, a plurality of PS packets may be included in the storage area T_sector, and the first frame of the frontmost PS packet in the storage area is an I-frame. Also, among the plurality of PS packets, the PS packet having the I-frame can be identified.

As shown in FIG. 6C, an I-frame is identified and displayed for each storage area, and the start frame of the storage area is always an I-frame. Also, there may be at least one I-frame in the storage area.

5, when the mobile terminal 100 receives a user operation corresponding to the image editing mode setting through the user input unit 130, the mobile terminal 100 sets the image editing mode using the controller 180 (S503) .

For example, the control unit 180 can set the image editing mode when the menu item corresponding to the image editing mode setting is selected through the menu search or when the key for commanding the image editing mode setting is selected.

Further, in the setting step S503, the image editing mode can be specifically set. For example, the image editing mode may include an image arrangement changing mode, a video adding mode, an image deleting mode, and the like.

Hereinafter, a process of selecting an image editing mode through a menu search in the mobile terminal will be described with reference to FIGS. 7A and 7B.

When the menu item corresponding to the image editing mode setting is selected through the menu search, the mobile terminal 100 can display the image list composed of the editable images through the display unit 151 (FIG. 7A). Here, the editable image is an image stored in the memory 160 on a storage area unit basis, a moving image captured and stored through the camera 122, a broadcast image received and stored through the broadcast receiving module 111, And a moving picture received from an external terminal through the wireless communication module 110 and stored therein.

When 'Program A' is selected in FIG. 7A, the mobile terminal 100 can display a list of edit methods that can be performed for 'Program A' through the display unit 151 (FIG. 7B). For example, the editing method list may include an arrangement change, an image addition, an image deletion, and the like.

Accordingly, the mobile terminal 100 can set a video editing mode corresponding to the editing method selected from the editing method list.

5, when the image editing mode is set by the control unit 180, the mobile terminal 100 may display a representative frame for each of the storage areas in which frames constituting an image to be edited are stored (S505).

For example, when a plurality of representative frames exist in one storage area, it is possible to display the representative frame located at the forefront, display the representative frame located at the forefront of each TS packet, or display all the representative frames.

Alternatively, when a representative frame among the representative frames displayed in the display step S505 is selected, the control unit 180 may decode and play back all the frames or some frames of the storage area including the selected representative frame. This is to assist the user in selecting the image to be edited.

Hereinafter, the image editing mode is divided into an 'arrangement change mode', an 'image addition mode', and an 'image deletion mode'.

First, a case where the 'arrangement change mode' is set as the image edit mode will be described.

When the arrangement change mode is set, the mobile terminal 100 selects a storage area to be moved and a position to be moved using the representative frames displayed in the display step S505 (S507).

For example, the user selects the first and second representative frames among the displayed representative frames through the numeric key or direction key operation, and the controller 180 moves the storage area corresponding to the first representative frame And the previous or next position of the second representative frame may be selected as the position to be moved of the storage area corresponding to the first representative frame.

Alternatively, when the touch screen is provided, the controller 180 may select a storage area corresponding to the first representative frame as a storage area to be moved as the touch operation is detected for the first and second representative frames, The previous or next position of the representative frame can be selected as the position to be moved in the storage area corresponding to the first representative frame. At this time, the touch operation for the first and second representative frames includes touch dragging from the first representative frame to the second representative frame, multi-touch for the first and second representative frames, touch for the first representative frame, and touch A touch for the second representative frame after the removal, and the like. This will be described later in detail with reference to Figs. 8A to 8C.

In addition, a plurality of storage areas to be moved can be selected by selecting a plurality of representative frames. Alternatively, when the storage areas corresponding to each of the plurality of representative frames are selected as a storage area to be moved, a different location to be moved may be selected for each storage area.

Then, the mobile terminal 100 can move the storage area selected in the selection step S507 to the selected position (S509).

For example, when the 'first and second storage areas' are selected as the storage areas to be moved and the 'fifth storage area' is selected as the location to be moved, the controller 180 controls the first and second storage areas And move to the next (or earlier) of the fifth storage area. Therefore, the storage area may be arranged in the order of the fifth storage area, the first storage area, the second storage area (or the first storage area, the second storage area, and the fifth storage area).

Hereinafter, with reference to FIG. 8A to FIG. 8C, a screen configuration in which arrangement among storage areas is changed according to a user's selection when the arrangement change is selected in FIG. 7B will be described. Here, it is assumed that the mobile terminal 100 has a touch screen, and representative frames are displayed on the touch screen.

7B, the controller 180 sets the arrangement change mode and sets a representative frame for each of the plurality of storage areas in which the frames constituting the program A (see the description of FIG. 7A) are stored Can be displayed on the touch screen (Fig. 8A). At this time, it may be displayed in order based on the order information specified in each of the storage areas.

8A, the user touches the first to third representative frames 151-1, 151-2, and 151-3 of the displayed representative frames to select a storage area to be moved have. Also, the user can select the eighth representative frame 151-8 corresponding to the position to be moved at one point of the touched first through third representative frames 151-1, 151-2, and 151-3 You can select the position to be moved by touch dragging to one point. Alternatively, a touch number, a touch time, a touch action, a confirmation key input, or the like may be used to distinguish a touch for selecting a storage area to be moved and a position to be moved.

As shown in FIG. 8A, the first to third representative frames 151-1, 151-2 and 151-3 are touch-dragged to the eighth representative frame 151-8, The first to third frames 151-1, 151-2, and 151-3 may be sequentially positioned at the next positions of the first to third frames (FIG. 8B). Therefore, the storage areas corresponding to the first to third frames 151-1, 151-2, and 151-3 are sequentially moved and positioned after the storage area corresponding to the eighth representative frame 151-8 .

8C, the control unit 180 determines whether the storage areas corresponding to the first to third frames 151-1, 151-2, and 151-3 are stored in the eighth representative frame 151-8 ), The order information for each storage area can be reset (S521). Accordingly, the order information of the storage areas corresponding to the eighth representative frame before the array change is reset in the eighth to fifth orders, and the order information of the storage areas corresponding to the first to third representative frames before the array change 1 to the third to sixth to eighth orders.

Next, a case where the 'image addition mode' is set as the image editing mode will be described.

When the image addition mode is set, the mobile terminal 100 may display a list of at least one additional target image (hereinafter referred to as 'additional target list') on the screen (S511).

For example, the addition target list may include a moving image, a still image, a recording broadcast program, and the like. Further, the addition target list can be displayed not only in a text format, but also in a thumbnail format.

The mobile terminal 100 selects an image to be added from the additional image list displayed in the display step S511, and selects a position to be added using the representative frames displayed in the display step S505 (S513).

More specifically, when a specific image is selected from the additional image list, the controller 180 converts a specific image into a TS packet form and transmits a plurality of frames constituting a specific image to at least one storage area And display representative frames of the respective storage areas on the screen. Accordingly, the user can select a storage area corresponding to a portion of a specific image to be added, by selecting a representative frame among the representative frames of the displayed storage areas.

As described above, the image to be added and the position to be added can be selected using the numeric key or direction key operation, or touch detection for the touch screen. Particularly, additional images and positions using touch detection on the touch screen will be described later in detail with reference to FIGS. 9A to 9E.

Then, the mobile terminal 100 may add a storage area corresponding to the selected image in the selection step S513 to the selected location (S515).

For example, the 'second and fourth storage areas' are selected as the storage areas to be added among the storage areas in which the selected image is stored, and the 'sixth storage area' among the storage areas in which the image to be edited is stored, If selected, the controller 180 may move the second and fourth storage areas to the next (or earlier) of the sixth storage areas. Therefore, the storage area can be arranged in the order of the sixth storage area, the second storage area, the third storage area, the fourth storage area (or the second storage area, the third storage area, the fourth storage area, and the sixth storage area) .

Hereinafter, with reference to FIGS. 9A to 9E, a screen configuration for adding a storage area according to a user's selection when image addition is selected in FIG. 7B will be described. Here, it is assumed that the mobile terminal 100 has a touch screen, and representative frames are displayed on the touch screen.

At this time, it may be displayed in order based on the order information specified in each of the storage areas.

9A, the control unit 180 displays the representative frames of the program A in one area of the touch screen and the additional image list in the other area in response to the 'additional area' for receiving the image addition command being touched by the user (Fig. 9B).

9B, when 'MOVIE 1' is selected from the additional image list, the controller 180 stops displaying the additional image list in the other area, and stores each of the plurality of frames constituting 'MOTION 1' (Fig. 9C). Therefore, the user selects the sixth frame 151-6 of the representative frames of the program A as a position to be added, and selects the second to fourth representative frames 151-2, 151 -3, 151-4) can be selected.

When the selection of the storage area and the position to be added is completed (for example, after the representative frame is selected, the 'completed area' is touched), the controller 180 displays the second to fourth representative frames 151-2 and 151 -3, and 151-4 may be added to the previous (or next) position of the storage area corresponding to the sixth representative frame 151-6 (FIG. 9D).

9E, the control unit 180 determines whether the storage areas corresponding to the second through fourth frames 151-2, 151-3, and 151-4 are stored in the sixth representative frame 151-6 ), The order information for each storage area can be reset (S521).

Next, a case where the 'image deletion mode' is set as the image edit mode will be described.

When the video deletion mode is set, the mobile terminal 100 selects a storage area to be deleted using the representative frames displayed in the display step S505 (S517).

For example, the user can select a storage area to be deleted by detecting a numeric key or a direction key operation by the user or a touch to the touch screen. The selection of the storage area to be deleted using the touch screen will be described later in detail with reference to FIGS. 10A to 10C.

In addition, a plurality of storage areas to be deleted can be selected by selecting a plurality of representative frames.

Then, the mobile terminal 100 can delete the storage area selected in the selection step S517 according to the control of the controller 180 (S519).

For example, when the 'first and second storage areas' are selected as the storage areas to be deleted, the controller 180 may delete the first and second storage areas.

Hereinafter, with reference to FIGS. 10A to 10C, a screen configuration for deleting a storage area according to a user's selection when image deletion is selected in FIG. 7B will be described. Here, it is assumed that the mobile terminal 100 has a touch screen, and representative frames are displayed on the touch screen.

7B, the control unit 180 sets the video erasure mode and sets a representative frame for each of the plurality of storage areas in which the frames constituting the program A (refer to the description of FIG. 7A) are stored Can be displayed on the touch screen (Fig. 10A). At this time, it may be displayed in order based on the order information specified in each of the storage areas.

10A, the user can select the storage area to be deleted by touching the second to fourth representative frames 151-2, 151-3, and 151-4 among the displayed representative frames have.

10A, when the selection of the storage area to be deleted is completed (for example, when the 'confirmation area' is touched after touching the representative frame), the control unit 180 displays the second through fourth representative frames 151 -2, 151-3, and 151-4, and does not display the second to fourth representative frames 151-2, 151-3, and 151-4 on the screen any more (Fig. 10B). Therefore, the first, fifth, and sixth representative frames may be arranged in this order.

As shown in FIG. 10C, as the storage areas corresponding to the second through fourth frames 151-2, 151-3, and 151-4 are deleted, The information can be reset (S521). Therefore, the order information of each of the storage areas corresponding to the 5th, 6th, 7th, ..., nth representative frames before deletion is the order information of the storage areas corresponding to the 5th, 6th, 7th, , 4 < th > ... n-3 < / RTI >
