11 shows a screen when the moving picture generating system 100 is in the editing mode. The control unit 150 may display an input control 123 for selecting a shooting mode or a storage mode in the first area 121 or the second area 122 of the display unit 120 have. 11 shows an example in which 'shooting' control and 'storage' control are displayed in the first area 121. In FIG.

As shown in FIG. 12, the control unit 150 can receive a selection command for all or a part of a plurality of image frames from the user through the user input unit 130 during the edit mode (S231).

11, in the edit mode, the control unit 150 displays all or a part of the plurality of image frames F1 to Fn extracted from the images photographed in the photographing mode in the second area 122 of the display unit 120 And display the image frame Fk displayed at the center of the second area 122 in the first area 121. [

At this time, the image frames displayed in the second area 122 of the plurality of image frames F1 to Fn may be changed according to a user's command input through the selection area 132. [ For example, assuming that the number of image frames that can be displayed in the selection region 132 is five and the number of image frames extracted from the image photographed in the photographing mode is ten, five image frames The five image frames displayed in the selection area 132 can be changed, thereby confirming all 10 image frames.

The control unit 150 can select all or a part of the plurality of image frames F1 to Fn according to a user's selection instruction inputted through the selection region 132 corresponding to the second region 122. [ The image frames selected by the user's selection command may be image frames that are continuous with each other, as well as image frames that are separated from each other.

Referring again to FIG. 12, the controller 150 may receive a user edit command for the image frame selected by the user (S232). The edit command is a command for applying a specific image filter to a selected image frame, inserting an icon, text, etc., as well as commands for moving, copying or deleting selected image frames or changing the arrangement order of selected image frames It is a concept to include.

In addition, the controller 150 may generate edit information for the image frame selected by the user using the edit command of the user (S233). Such editing information may include effect information to which a specific image filter is applied to an image frame selected by the user, or object information including an icon, text, or the like. Further, the editing information may include movement information, copy information, erasure information, and arrangement order information of the image frame selected by the user.

For example, as shown in FIG. 11, when the text "WOW!" Is added to an image frame of 1 second to 2 seconds in the edit mode for an image photographed for 8 seconds in the photographing mode, (8 seconds), time information (1 second to 2 seconds) in which the text object "WOW!" Is inserted, insertion position information (X pixels, Y pixels) of the text object "WOW!" have.

11 illustrates a case where a text object is added to an image frame selected by the user in the edit mode. However, the present invention is not limited to this example. Alternatively, the selected image frame may be moved, copied or deleted, Can also be performed.

Finally, as shown in FIG. 12, the control unit 150 may temporarily store edit information on the image frame selected by the user in the storage unit 140 (S234). As described above, since the storage unit 140 is constituted by the first memory for temporarily storing various data and the second memory for finally storing various data, the editing information for the image frame selected by the user is stored in the first memory May be stored, but may be stored in the second memory as needed.

As described above, the moving image generating system 100 according to an exemplary embodiment of the present invention extracts a plurality of image frames from a captured image and sequentially displays the selected image frames, selects only image frames to be edited among a plurality of image frames, The user can perform the video editing operation more quickly and intuitively.

9 to 12 illustrate a smart phone as an example of the moving image generating system 100 according to an embodiment of the present invention. However, the present invention is not limited thereto, Various types of information communication devices and multimedia devices such as a general computer (PC) as well as a mobile communication terminal such as a tablet PC can be used.

As described above, according to the moving image generating method according to the embodiment of the present invention, after the editing operation is performed in real time on the image taken when the image is taken, the image data can be generated and stored, Since the video creation work and the video editing work which were performed separately can be performed simultaneously in real time, the user can perform the video creation and editing work more quickly, intuitively and easily. During the editing mode, temporal image data and editing information are generated separately from the images photographed in the photographing mode, temporarily stored, and unit image data is generated from the temporary image data using the editing information in the storage mode Thereby increasing the speed and performance of moving image creation and editing operations, thereby increasing the efficiency of video creation and editing operations. In addition, a plurality of image frames are extracted from the captured image and displayed sequentially, and only an image frame desired to be edited among a plurality of image frames is selected and an editing command is input, thereby allowing the user to perform a moving image editing operation more quickly and intuitively .
