6, the zoom data 700 may include at least one of a storage order 701, a time line 702, a position coordinate 703, and a zoom level 704.

The storage order 701 may indicate the order of the reproduction points at which the enlargement magnification or enlargement area is changed in association with one zoom recording image. Specifically, the control unit 170 accumulates and stores zoom data corresponding to the live zoom executed every time the live zoom is performed in association with one zoom recording image. Accordingly, the storage order 701 may indicate a storage order of the zoom data corresponding to the live zoom. According to the example of the zoom data shown in FIG. 6, the enlarged magnification / enlargement can be changed three times in comparison with the original image in the zoom recording image. However, the storage order 701 may be omitted in the zoom data 700. [

The time line 702 may indicate the reproduction time of the image at the time when the enlargement magnification or enlargement position of the image is changed. According to one example shown in Fig. 6, the timeline of the first zoom data is 001230, the timeline of the second zoom data is 002050, and the timeline of the third zoom data is 010010. This indicates that the enlargement ratio or enlargement area is changed at the video reproduction time 00:12:30, 00:20:50, 01:00:10, respectively.

The position coordinate 703 may mean coordinate information of the pointer 205 that is a reference for changing the enlarged area. The control unit 170 may receive an instruction to change the enlarged area through the pointer 205. [ For example, when the controller 170 receives an instruction to select one region by the pointer 205, the control unit 170 may change the enlarged region of the image so that the selected region is located at the center of the display unit 180. Accordingly, the coordinates of the area selected through the pointer 205 may be the position coordinates of the zoom data. Coordinates can be composed of x and y coordinates. 6, the control unit 170 changes the enlarged area so that the area corresponding to the coordinates 1200, 720 is positioned at the center of the display unit 180 at the image reproduction time 00:12:30 The enlarged area is changed so that the area corresponding to the coordinate information 800, 400 is positioned at the center of the display unit 180 at the video reproduction time 00:20:50, The enlarged area can be changed so that the area corresponding to the information 1010 and 560 is located at the center of the display unit 180. [

The zoom level 704 may mean enlargement ratio information that is changed in comparison with the original image. For example, if the zoom level is 1, it can mean an original image of x1 magnification. The control unit 170 may control the magnification factor of the original image to be increased by 0.1 as the zoom level increases by one. Specifically, zoom level 1 represents an original image at x1 magnification, zoom level 2 represents an image whose original image is enlarged at x1.1 magnification, zoom level 3 represents an image whose original image is magnified at x1.2 magnification , And the zoom level 7 can display the original image enlarged at x1.6 magnification. According to the example shown in FIG. 6, the controller 170 enlarges and displays the original image at x1.6 magnification at the image reproduction time 00:12:30, and displays the original image at x1. And the original image is enlarged and displayed at x1.3 magnification at the image reproduction time 01:00:10. The zoom level described above is an example, and the magnification information may be stored in another form.

The storage unit 140 may store the zoom data in the form of 01_001230_1200_720_07, 02_002050_800_400_05, and 03_010010_1010_560_04. However, this is merely exemplary and not limited thereto. In addition, the storage unit 140 may omit some items or may further include other items in the zoom data shown in Fig.

Since the zoom data 700 is stored in a text format, the size of the space occupying the storage unit 140 can be greatly reduced. That is, if the zoom recording image other than the original image is stored as the image itself, the capacity may be very large. However, as in the present invention, when the zoom recording image is stored in the form of text format zoom data in addition to the original image, the capacity can be greatly reduced.

Next, a method of recording a zoom recording image according to an embodiment of the present invention will be described with reference to FIG. 7 to FIG.

[

The control unit 170 can execute zoom recording upon receiving a command to select the zoom recording icon 1011. [

8 will be described again.

As the zoom recording is performed, the control unit 170 can control to display a zoom recording screen including the viewfinder (S103).

According to the second embodiment of the present invention, the controller 170 can record the zoom recording video through the viewfinder.

Next, a zoom recording screen including a viewfinder according to an embodiment of the present invention will be described with reference to FIG. 11 is a view for explaining a zoom recording screen including a viewfinder according to an embodiment of the present invention.

When the zoom recording is performed on the display unit 180, a zoom recording screen as shown in Fig. 11 can be displayed.

The zoom recording screen includes at least one of a viewfinder 1101, zoom recording recording time information 1102, magnification ratio information 1103, a storage icon 1104, a cancel icon 1105, can do.

First, the viewfinder 1101 will be described.

The controller 170 displays the original image on the full screen and displays the viewfinder 1101 on one area of the original image as the zoom recording is performed. The control unit 170 displays an area to be recorded as a zoom recording image in the viewfinder 1101. [ That is, the viewfinder 1101 represents an area to be recorded as a zoom recording image.

When an enlarged image is displayed on a full screen and recorded, some areas may not be displayed. In this case, there is a problem that a specific area to be recorded may be missed. Accordingly, it is an object of the present invention to provide a method of facilitating zoom recording with reference to an original image.

When the zoom recording is performed, the control unit 170 can control the area displayed on the viewfinder 1101 to be recorded as a zoom recording image. Specifically, the controller 170 can control the position information of the viewfinder bulb 1101 and the enlargement ratio information when the image of the area of the viewfinder 1101 is displayed on the full screen. The control unit 170 controls the reproduction time point of the instant when the viewfinder 1101 is changed, the coordinates of the right center region of the viewfinder 1101, and the enlargement magnification when the image of the viewfinder 1101 region is displayed on the full screen It can be saved as data.

The control unit 170 can control to record the zoom recording video while playing back from the playback point for performing zoom recording. If the control unit 170 is in the pause state immediately before the zoom recording is performed, the control unit 170 can record the zoom recording image while changing to the playback state as the zoom recording is performed.

As described above, according to the second embodiment of the present invention, when an area to be recorded with the original image and the zoom recording image is displayed on the entire screen, it is possible to easily confirm and change the recording area.

The control unit 170 can control to display the viewfinder 1101 while maintaining the enlargement magnification or enlargement area when zoom recording is performed in a state in which the enlargement magnification or enlargement area is changed. That is, the control unit 170 can control the viewfinder 1101 to be displayed in the enlarged area. For example, when zoom recording is performed in a state in which one area of the image is enlarged as shown in Fig. 10, an enlarged area may be displayed to be included in the viewfinder 1101 as shown in Fig. 11 .

In addition, the controller 170 may display the outer area of the viewfinder 1101 darker than the inner area of the viewfinder 1101. In this case, there is an effect that the user can easily grasp the recording area.

The configuration for moving or changing the viewfinder 1101 will be described later.

Next, the zoom recording recording time information 1102 will be described.

The zoom recording recording time information 1102 includes the time at which the zoom recording video is recorded. As the control unit 170 executes the zoom recording, the control unit 170 can count the zoom recording recording time from 0 seconds. The zoom recording recording time information 1102 may further include an icon indicating a recording state.

In the example of FIG. 11, the zoom recording recording time information 1102 is included in the viewfinder 1101. FIG. However, this is an illustrative example, and the zoom recording recording time information 1102 may be located in any area including the outside of the viewfinder 1101. [

Next, the magnification ratio information 1103 will be described.

The enlargement magnification information 1103 includes an enlargement magnification when the image of the area of the viewfinder 1101 is displayed in full screen. Accordingly, the controller 170 can adjust the size of the area of the viewfinder 1101 according to the enlargement magnification. A detailed description thereof will be given later with reference to FIG. Likewise, the magnification information 1103 can be located in any area including the inside and outside of the viewfinder 1101. [

The storage icon 1104 is an icon for storing the zoom recording image being recorded. The cancel icon 1105 is an icon for canceling the zoom recording video being recorded and deleting the recorded data. The storage icon 1104 and the cancel icon 1105 will be described later with reference to FIG. 17 to FIG.

The video playback time 1106 represents the current playback time and the total playback time of the video being displayed by the display unit 180. [

8 will be described again.

The control unit 170 may control to record an image in the viewfinder area 1101 (S105).

Specifically, the controller 170 may store an enlargement magnification and enlargement area for enlarging the area displayed on the viewfinder 1101 to the full screen. For example, the control unit 170 may control the playback time of the instant of change, the coordinates of the center region of the viewfinder 1101, and the enlargement magnification as zoom data whenever the viewfinder 1101 is changed.

The control unit 170 can determine whether or not the viewfinder moving command has been received (S107).

Upon receiving the viewfinder movement command, the control unit 170 may control to display the viewfinder 1101 at a position corresponding to the viewfinder movement command (S109).

The user can move the viewfinder to another area to change the enlarged area. The controller 170 can change the position of the viewfinder upon receiving the viewfinder movement command.

Next, a viewfinder moving command according to an embodiment of the present invention will be described with reference to FIGS. 12 to 13. FIG.

12 is a view for explaining a viewfinder moving command according to the first embodiment of the present invention.

As shown in FIG. 12, the controller 170 may receive a command to select one point of the display unit 180 as the pointer 205. FIG. The controller 170 can move the position of the viewfinder 1101 with respect to the area selected by the pointer 205. [ Specifically, the controller 170 may move the viewfinder 1101 such that the center of the viewfinder 1101 is positioned at a point selected by the pointer 205. [ As described above, according to the first embodiment of the present invention, it is possible to receive the viewfinder movement command through the simple area selection through the pointer 205. [ According to the first embodiment of the present invention, the viewfinder 1101, which is a recording area, can be conveniently moved.

13 is a view for explaining the viewfinder moving command according to the second embodiment of the present invention.

The control unit 170 may receive a command to drag and drop from one point 1301 to another point 1302 of the display unit 180 as shown in FIG. Accordingly, the control unit 170 can move the viewfinder 1101 located at one point 1301 to be positioned with respect to the other point 1302. Specifically, when the control unit 170 receives a command to select one of the internal areas of the viewfinder 1101 through the pointer 205 and drag the pointer, the controller 170 controls the viewfinder 1101 ) Can be moved and displayed. Upon receipt of the drop instruction, the control unit 170 can display the view finder 1101 based on the position of the pointer 205 at the moment the drop instruction is received. As described above, according to the second embodiment of the present invention, the position of the viewfinder 1101 can be moved by dragging and dropping through the pointer 205. [ In this case, the user has the effect of previewing the area to be recorded through the viewfinder 1101.

On the other hand, when the position of the viewfinder 1101 is moved according to the drag and drop command, the controller 170 may control to record the image of the area of the viewfinder 1101 being moved. In this case, there is an effect that the user can finely set an area to be recorded through the viewfinder 1101. [

8 will be described again.

If the controller 170 does not receive the viewfinder movement command, the control unit 170 can determine whether the magnification change command has been received (S111).

Upon receiving the enlargement magnification change command, the controller 170 can adjust the magnitude of the viewfinder according to the magnification change command (S113).

The control unit 170 may change the magnification of the viewfinder 1101 and display it as the magnification of the image is changed. Specifically, the controller 170 may reduce the size of the viewfinder 1101 when the magnification of the image increases, and increase the size of the viewfinder 1101 when the magnification of the image decreases. This is because as the enlargement magnification is increased, the area to be recorded on the original image is reduced, and as the enlargement magnification is lowered, the area to be recorded on the original image becomes wider. Therefore, the user can change the area of the area to be recorded by adjusting the enlargement magnification.

14 is an exemplary view for explaining the size adjustment of the viewfinder according to the embodiment of the present invention.

Specifically, the size of the viewfinder according to the enlargement magnification will be described with reference to the example diagram in Fig. 11 and the example diagram in Fig.

First, in the example of Fig. 11, the enlargement magnification is x1.5. This can be known by 150%? K indicated in the magnification information 1103 in Fig. On the other hand, in the example of Fig. 14, the enlargement magnification is x3.0. This can be known through 300% indicated in the enlargement magnification information 1103 in Fig. At this time, it can be confirmed that the viewfinder 1104 shown in Fig. 14 is larger in size than the viewfinder 1101 shown in Fig.

When the controller 170 receives the enlargement magnification change command, the controller 170 can adjust the size of the viewfinder 1101 to a size corresponding to the changed enlargement magnification. As described above, the area of the recording area can be easily adjusted by displaying the viewfinder 1101, which is an area to be recorded with the original image, and adjusting the size of the viewfinder 1101 according to the enlargement magnification. That is, the degree of change of the enlargement magnification can be accurately grasped as compared with the case where the area to be recorded is displayed in a full screen.

8 will be described again.

If it is determined that the magnification change command has not been received, the controller 170 may determine whether movement of the pointer 205 has not been detected during the first time (S115).

The controller 170 may sense the movement of the pointer 205. [ In particular, the controller 170 may detect whether the pointer 205 has moved for a preset time. If the controller 205 detects that the pointer 205 is not moving for a preset time, the control unit 170 may control to remove icons, information, and the like displayed on the screen. This is because if the pointer 205 does not move, it is determined that the user has performed all the necessary information confirmation and necessary operations, so that the screen is minimized and displayed. Thereby, the power consumption can be reduced.

On the other hand, the controller 170 can minimize the screen in a stepwise manner. Accordingly, first, the controller 170 may set a first time for minimizing the viewfinder 1101. [ Then, the controller 170 may set a second time for minimizing the zoom recording screen. At this time, the minimization of the viewfinder 1101 may be included in the minimization of the zoom recording screen, and the first time is smaller than the second time. For example, the first time may be 5 seconds and the second time may be 30 seconds. A method of minimizing the viewfinder 1101 and a method of minimizing the zoom recording screen will be described in detail below.

If it is determined that the movement of the pointer 205 is not detected during the first time, the control unit 170 may minimize the viewfinder 1101 (S117).

Thereafter, if it is determined that the movement of the pointer 205 is not detected during the second time (S119), the control unit 170 may minimize the zoom recording screen (S121).

15 is a view for explaining a method of minimizing a viewfinder according to an embodiment of the present invention, and FIG. 16 is a view for explaining a method of minimizing a zoom recording screen according to an embodiment of the present invention.

The controller 170 can minimize the viewfinder 1101 if the movement of the pointer 205 is not detected during the first time. Specifically, as shown in FIG. 15, the controller 170 may remove at least one or more pieces of information displayed in the viewfinder 1101. In this way, the controller 170 can display only the area to be recorded by removing information displayed inside the viewfinder 1101 over a predetermined time.

On the other hand, if the movement of the pointer 205 is not detected for the second time after the first time, the controller 170 can minimize the zoom recording screen. 16, the controller 170 may remove the mode icon, information, and the viewfinder 1101 except for the video playback time information 1610. In this case,

The image reproduction time point information 1610 includes the current reproduction time point and the total reproduction time of the image. In addition, the image playback time information 1610 may further include a recording schedule icon 1611. FIG.

The recording / non-recording icon 1611 indicates whether or not zoom recording is being executed. The control unit 170 may minimize the zoom recording screen to indicate that the current zoom recording image is being recorded through the recording icon 1611 even if the viewfinder 1101 is removed.

More specifically, the controller 170 removes the viewfinder 1101 on the screen if the movement of the pointer 205 is not detected for the second time, but the viewfinder 1101 area It is possible to continuously record the area 1601 that is the same as the area 1601. Thereby, when the viewfinder 1101 is not scheduled to be changed, there is an effect that recording can be continued and the screen can be minimized.

The control unit 170 may cancel minimization of the viewfinder 1101 or minimization of the zoom recording screen when the movement of the pointer 205 is detected after the viewfinder 1101 is minimized or the zoom recording screen is minimized. That is, when the motion of the pointer 205 is detected, the controller 170 may display at least one icon, information, and viewfinder 1101 that have been removed.

8 will be described again.

The control unit 170 can determine whether the zoom recording cancel command has been received (S123).

Upon receiving the zoom recording cancel command, the control unit 170 can delete the image of the recorded viewfinder 1101 area (S125).

On the other hand, if the zoom recording cancel command is not received, the control unit 170 can determine whether the zoom recording recording command has been received (S127).

Upon receiving the zoom recording storage command, the controller 170 may store the image of the recorded viewfinder 1101 area (S129).

The control unit 170 may receive a zoom recording cancel command or a zoom recording storage command to delete or store the recorded image.

Next, a method for deleting or storing a recorded image according to an embodiment of the present invention will be described with reference to FIG. 17 to FIG. 17 to 18 are diagrams for explaining a method of storing a recorded video according to an embodiment of the present invention, and FIGS. 19 to 20 are views for explaining a method of deleting a recorded video according to an embodiment of the present invention to be. 21 is a view for explaining a recorded zoom recording image according to an embodiment of the present invention.

Upon receipt of the instruction to select the save icon 1104, the controller 170 may control the storage unit 140 to store the image of the recorded viewfinder 1101 area. Accordingly, the controller 170 can display the storage guidance window 1801 as shown in FIG. The storage guidance window 1801 indicates whether the zoom recording image is successfully stored or failed. In addition, the storage guidance window 1801 includes a storage location of the zoom recording image when the storage is successful. The storage guidance window 1801 includes a reason for failure of the zoom recording image when storage fails.

Alternatively, as shown in FIG. 19, the control unit 170 may receive an instruction to select the cancel icon 1105. FIG. Upon receiving the command to select the cancel icon 1105, the control unit 170 can control to delete the image of the recorded viewfinder 1101 area. Accordingly, as shown in Fig. 20, the control unit 170 can control to display the cancel confirmation window 2001. [ The cancel confirmation window 2001 is responsible for re-checking whether or not to delete the recorded zoom recording image. The control unit 170 may control to delete or delete the recorded zoom recording image through the cancel confirmation window 2001. [

In this way, the controller 170 can delete or store the recorded image to end the zoom recording.

When the zoom recording is terminated, the playback time of the zoom recording image may be as shown in FIG. That is, referring to the progress bar 2101 of the original image and the progress bar 2102 of the zoom recording image shown in FIG. 21, from the time point when the zoom recording icon 2103 is selected until the storage icon 2104 is selected An image of the area of the viewfinder 1101 can be recorded while the original image is being reproduced.

22 is a flowchart illustrating a method of managing a zoom recording image according to an embodiment of the present invention. The flowchart shown in FIG. 22 may be a flowchart that extends the flowchart shown in FIG.

Upon receipt of the zoom recording cancel / store command in S125 or S129 of FIG. 8, the controller 170 can continuously reproduce the image from the point of time of receiving the zoom recording cancel / store command (S129).

That is, the controller 170 can continuously reproduce the video regardless of the reception of the zoom recording cancel / store command.

The control unit 170 can receive the image list display command (S203).

The image list display command is a command for displaying a list of images stored in the storage unit 140.

Upon receipt of the image list display command, the control unit 170 may display the image list including the original image and the zoom recording image (S205).

23 is a view for explaining an image list display method according to an embodiment of the present invention.

As shown in FIG. 23, the controller 170 may display an original image and a corresponding zoom recording image together.

The control unit 170 can adjust the image selection according to whether the selected image is an original image or a zoom recording image through the item selection icon 2410. [

Specifically, the controller 170 may determine whether the selected video item is an original video item (S211).

If the selected image item is an original image item, the controller 170 may check both the original image item and the corresponding zoom recording image (S213).

That is, when the original image item is selected, the controller 170 may check all the item selection icons 2410 of the original image and the corresponding zoom recording image.

If the selected image item is not an original image item, the controller 170 may check only the selected image item (S215).

That is, when the zoom recording image item is selected, the control unit 170 can check and display only the item selection icon 2410 of the selected zoom recording image.

25 to 26 are diagrams for explaining a method of selecting an image item to delete an image according to an embodiment of the present invention.

Referring to FIG. 25, the controller 170 may check an item selection icon 2410 of the selected zoom recording image if the selected image item is a zoom recording image, as described above.

On the other hand, referring to FIG. 26, the controller 170 may check all the item selection icons 2410 of the original image and the corresponding zoom recording image if the selected image item is an original image. This is because the zoom recording video can not be executed when the original video is deleted, so that the zoom video corresponding to the original video is deleted. Thereby, there is an effect of preventing the case where the impossible zoom recording video is displayed on the video list.

Meanwhile, when the original image is selected, the controller 170 may deactivate the item selection icon 2410 of the zoom recording image when selecting the zoom recording image. The control unit 170 prevents the clearing of the check by deactivating the item selection icon 2410 of the checked video item. Accordingly, the control unit 170 controls the check of the zoom recording image not to be released in a state where the check of the original image is not canceled. Thereby, there is an effect that it is possible to prevent the case where the original image is deleted but the zoom recording image is not deleted.

The control unit 170 can cancel the check as it receives the command to reselect the check video item. A detailed description thereof will be described later.

The control unit 170 may receive an instruction to reselect the check video item (S217).

Upon receiving the command to reselect the check video item, the controller 170 may determine whether the reselected check video item is a zoom recording video item (S219).

If the reselected check video item is not a zoom recording video, the reselected check video item may be the original video. Accordingly, when the original image is reselected, the controller 170 can cancel checking of the reselected original image item and the corresponding zoom recording image item. This is to prevent the case where the original image is erased but the zoom recording image is not erased as described above.

If the reselected check video item is a zoom recording video item, the controller 170 may determine whether the original video corresponding to the zoom recording video item is checked (S221).

If the original image corresponding to the zoom recording image item is checked, the controller 170 keeps the re-selected image item checked (S223).

When the item selection icon 2410 of the original image is checked, the item selection icon 2410 of the zoom recording image may be checked and deactivated at the same time.
