Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as " proximity touch & The act of actually touching an object on the screen is called a " contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have.

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The first and second operation units 123a and 123b may be collectively referred to as a manipulating portion as an example of a user input unit 123 operated to receive a command for controlling the operation of the mobile terminal 100 have. The first and second operation units 123a and 123b can be employed in any manner as long as the user is in a tactile manner such as touch, push, scroll, or the like. In addition, the first and second operation units 123a and 123b may be employed in a manner that the user operates the apparatus without touching the user through a proximity touch, a hovering touch, or the like.

In this figure, the first operation unit 123a is a touch key, but the present invention is not limited thereto. For example, the first operation unit 123a may be a mechanical key, or a combination of a touch key and a touch key.

The contents input by the first and second operation units 123a and 123b can be variously set. For example, the first operation unit 123a receives a command such as a menu, a home key, a cancellation, a search, and the like, and the second operation unit 123b receives a command from the first or second sound output unit 152a or 152b The size of the sound, and the change of the display unit 151 to the touch recognition mode.

On the other hand, a rear input unit (not shown) may be provided on the rear surface of the terminal body as another example of the user input unit 123. The rear input unit is operated to receive a command for controlling the operation of the mobile terminal 100, and input contents may be variously set.

The rear input unit may be implemented as a touch input, a push input, or a combination thereof.

The rear input unit may be disposed so as to overlap with the front display unit 151 in the thickness direction of the terminal body. For example, the rear input unit may be disposed at the rear upper end of the terminal body such that when the user holds the terminal body with one hand, the rear input unit can be easily operated using the index finger. However, the present invention is not limited thereto, and the position of the rear input unit may be changed.

When a rear input unit is provided on the rear surface of the terminal body, a new type of user interface using the rear input unit can be realized. When the first operation unit 123a is not disposed on the front surface of the terminal body in place of at least a part of the functions of the first operation unit 123a provided on the front surface of the terminal body, The display unit 151 may be configured as a larger screen.

Meanwhile, the mobile terminal 100 may be provided with a fingerprint recognition sensor for recognizing the fingerprint of the user, and the controller 180 may use the fingerprint information sensed through the fingerprint recognition sensor as authentication means. The fingerprint recognition sensor may be embedded in the display unit 151 or the user input unit 123.

The microphone 122 is configured to receive the user's voice, other sounds, and the like. The microphone 122 may be provided at a plurality of locations to receive stereophonic sound.

The interface unit 160 is a path through which the mobile terminal 100 can be connected to an external device. For example, the interface unit 160 may include a connection terminal for connection with another device (for example, an earphone or an external speaker), a port for short-range communication (for example, an infrared port (IrDA Port), a Bluetooth port A wireless LAN port, or the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented as a socket for receiving an external card such as a SIM (Subscriber Identification Module) or a UIM (User Identity Module) or a memory card for storing information.

And a second camera 121b may be disposed on a rear surface of the terminal body. In this case, the second camera 121b has a photographing direction which is substantially opposite to that of the first camera 121a.

The second camera 121b may include a plurality of lenses arranged along at least one line. The plurality of lenses may be arranged in a matrix form. Such a camera can be named an 'array camera'. When the second camera 121b is configured as an array camera, images can be taken in various ways using a plurality of lenses, and a better quality image can be obtained.

The flash 124 may be disposed adjacent to the second camera 121b. The flash 124 shines light toward the subject when the subject is photographed by the second camera 121b.

And a second sound output unit 152b may be additionally disposed in the terminal body. The second sound output unit 152b may implement a stereo function together with the first sound output unit 152a and may be used for implementing a speakerphone mode in a call.

For example, an antenna constituting a part of the broadcast receiving module 111 (see FIG. 1A) may be configured to be able to be drawn out from the terminal body. Alternatively, the antenna may be formed in a film type and attached to the inner surface of the rear cover 103, or a case including a conductive material may be configured to function as an antenna.

The terminal body is provided with a power supply unit 190 (see FIG. 1A) for supplying power to the mobile terminal 100. The power supply unit 190 may include a battery 191 built in the terminal body or detachable from the outside of the terminal body.

The battery 191 may be configured to receive power through a power cable connected to the interface unit 160. In addition, the battery 191 may be configured to be wirelessly chargeable through a wireless charger. The wireless charging may be implemented by a magnetic induction method or a resonance method (magnetic resonance method).

The rear cover 103 is configured to be coupled to the rear case 102 so as to cover the battery 191 to restrict the release of the battery 191 and to protect the battery 191 from external impact and foreign matter . When the battery 191 is detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

The mobile terminal 100 may be provided with an accessory that protects the appearance or supports or expands the function of the mobile terminal 100. [ One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the mobile terminal 100. [ The cover or pouch may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100. Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

In the mobile terminal 100 according to the embodiment of the present invention described above, when the edit mode is executed after the zoom photographed image is stored, the original image, which is not the zoomed photographed image but is zoomed out, ). In this case, a graphic object corresponding to the zoomed-in image is displayed on the original image. The user can control the graphic object displayed through the touch to edit the zoom photographed image. Specifically, the control unit 180 recognizes the control of the graphic object and performs editing by changing the zoom-related meta data matched to the zoom-captured image. According to this, it is possible to access the original file, not the zoom-captured image, and to edit the zoom area on the basis of the original file without limitation.

Hereinafter, FIG. 2 is a diagram for specifically explaining operations implemented in a mobile terminal related to the present invention.

Referring to FIG. 2, the first image 201 zoomed on the touch screen 151 of the mobile terminal 100 according to the present invention is displayed. Here, the first image photographed by the zoom may be a still image or a video. In addition, the first image obtained by zooming includes all of zooming in / zooming out in the case of zooming only a part of the original file. That is, if the zoom is performed and stored at least once during the image capturing, the first image 201 can be included in the zoom captured image 201.

If the zoom-captured first image is a moving image, it can be said that the first image zoomed in is reproduced on the touch screen 151 (FIG. 2A). Also, the first image 201 may include one or more subjects 211 as shown in FIG.

Next, when an edit mode for the first image 201 is executed, the original image 202 including the first image 201 zoomed out as shown in FIG. 2 (b) (151). Meanwhile, the execution of the edit mode may be performed when a predetermined combination of hard key input, predetermined voice input, preset touch gesture, and the like is received, and a detailed description thereof will be omitted.

If the original image 202 is a moving image file, it may be provided in the form of a still image at the beginning of the edit mode. In this case, the stopped image may be the first frame of the original image 202, the last frame, or the frame corresponding to the time point when the first image 201 is temporarily stopped. In another example, for quick editing of the zoomed shot image, it may be the first frame at the time when the zoom shot is performed on the original image 202 regardless of the playback time of the first image 201. [

In the edit mode, when the original image 202 corresponds to the zoom photographing time, the graphic object 221 corresponding to the first image 201 zoom-photographed is displayed on the original image 202.

Here, the graphical object 221 corresponding to the first image 201 may include data, text, images, or a combination thereof that can be visually perceived by the user, such as zoom related information corresponding to the first image 201 can do. Here, the zoom-related information may mean metadata including at least one of a size of a zoom area corresponding to the first image 201 and a position of a zoom area. In addition, the metadata may include a time point at which the zoom is photographed, and a position and size of a zoom area in the original image. In addition, the position and size of the zoom area may be represented by x, y coordinate values based on the original image.

In addition, the graphical object 221 may display information indicating a position and a size of a zoom area corresponding to the first image 201. In one example, the graphic object 221 may be in the form of a rectangular frame representing a zoom area, which is superimposed within the original image 202, as shown in FIG. However, the present invention is not limited to this, and as another example, a zoom photographed image may be displayed in a PIP format in the original image 202, or the entire zoom area may be highlighted. In this case, since the user can simultaneously check the zoom area within the original image 202, it is possible to easily perform the editing later.

2C, the graphic object may be moved from the first position to the second position based on the drag-touch input applied to the graphic object 221 displayed in the original image 202. [ For example, by dragging a touch on one point on the frame line of the graphic object 221 to a desired position, the position of the graphic object can be changed.

Meanwhile, in another example, when a touch input is applied to the graphic object 221, a new second graphic object 221m is displayed at a second position while maintaining the first graphic object 221 displayed at the first first position It is possible. In this case, the color or frame line shape (e.g., dotted line, solid line, line thickness) of the first graphic object 221 and the second graphic object 221m may be displayed differently. Accordingly, the user can visually easily compare the zoom area before editing and the zoom area after editing.

When the position of the graph object displayed on the original image 202 is changed (221m), the controller 180 can change the position of the zoom area among the zoom-related information corresponding to the first image 201 . Specifically, the controller 180 determines whether the x, y coordinates corresponding to the first graphic object 221 displayed at the first position are x, y coordinates corresponding to the graphic object 221m displayed on the second value After being substituted, selected or stored, the metadata corresponding to the first image 201 is changed.

Accordingly, as shown in FIG. 2D, when the play mode is executed, the zoom image 203 corresponding to the changed metadata is reproduced on the touch screen 151. Specifically, the controller 180 parses the changed metadata, and then crops the original image 202, thereby configuring and playing the edited new zoom image 203. Compared with FIG. 2 (a), it can be seen that the zoom area is changed and played.

On the other hand, although not shown, the first image zoomed in is no longer recorded due to the change of the metadata. However, the user may be able to set the first image zoom-captured at the time of photographing or before editing to be recorded as an original file regardless of editing.

As described above, in the embodiment of the present invention, when editing a zoom photographed image, editing can be performed without restriction by accessing a zoomed-out original file rather than a zoomed photographed image. In addition, since the area photographed by the zoom in the original file can be visually confirmed and the before and after editing of the zoom area can be visually easily compared, the efficiency of editing the zoomed image is increased.

Hereinafter, FIG. 3 is a representative flowchart for explaining an operation implemented in a mobile terminal related to the present invention.

Referring to FIG. 3, a step of displaying a zoomed-in first image on the touch screen 151 of the mobile terminal 100 is started (S10). Here, the first image may be a still image or a video stored in the mobile terminal 100 by zooming. Or may be a still image or video downloaded from another device or server communicating with the mobile terminal 100. [ In any case, it means a moving image including a still image or a moving image including at least one zoom shooting section.

Next, when the edit mode is executed (S20), the zoomed-out original image of the zoomed-in first image is displayed (S30). Here, the edit mode is limited to the zoom-related editing, but it is needless to say that the zoom-related editing can be implemented by including one function as one tool in a general image editing mode.

On the other hand, the graphic object corresponding to the zoomed-in first image is superimposed on the original image (S40). At this time, if the zoomed-in image is a still image, the original image may be a zoomed-out still image. If the zoomed-out image is a moving image, the original image may include a zoom shooting segment and a segment not zoomed. In this case, the graphic object may appear on the original image when the displayed reproduction time point of the original image or the still image corresponds to the zoom photographed section.

The graphical object refers to a display indicating a zoomed area within an original image, and may be displayed in the form of text, highlighting, etc. in addition to an image such as a rectangular frame. Also, when a plurality of zoom photographs are taken from one original file, the graphic object indicating the zoomed area may be changed accordingly. For example, the size can be varied or moved based on the zoom-related information displayed or stored only in the zoom shooting interval.

Next, when a touch input is applied to the graphic object displayed in the original image, the graphic object moves or changes in size corresponding to the touch input, and the zoom-related information matching the first captured image is changed (S50) .

The touch input may refer to a drag touch input applied to the graphic object. Specifically, when a touch applied to one point of the graphic object is dragged, the position of the graphic object along the dragged path can be moved. The position of the zoom area corresponding to the graphic object can be changed accordingly.

As another example, the size of the graphic object may be increased / decreased as at least one of the touch points of the touch input applied to two points of the graphic object is dragged toward or away from the other point. Accordingly, the size of the zoom area corresponding to the graphic object can be changed.

At this time, if the size of the graphic object exceeds the reference range, the zoom area may be released and the original magnification may be restored.

Also, if the x and y coordinates of the zoom area corresponding to the graphic object are changed based on the moved position or the variable size, the existing metadata is updated with the changed information. Thereafter, as the updated metadata is rendered on the original image, a new zoom image is reproduced.

4, 5, 6A, 6B, 7, 8, and 9 are diagrams for explaining an operation of editing a zoomed image by using a zoom image Illustrations showing examples.

First, FIG. 4 shows an example in which the zoom shooting section to be edited using the time line in the edit mode is quickly searched and the zoom magnification is changed. Referring to FIG. 4A, for example, when a zoom photographed image stored in the mobile terminal 100 is selected through the gallery application, the zoom image 401 selected on the touch screen 151 is displayed.

Thereafter, based on the preset user input, the user can enter the edit mode and perform zoom editing. Here, the predetermined user input may be any combination of predetermined hard keys, a predetermined voice command, and a predetermined touch gesture, and there is no particular limitation on the user input for entering the edit mode.

When the edit mode is executed, the control unit 180 calls the original image zoomed out in the memory area (hereinafter referred to as 'first memory area') where the original image is stored. Then, in the separate memory area (hereinafter referred to as 'second memory area') in which the zoom-related data is stored, the metadata in which the zoom photographing time and zoom area are recorded is parsed.

The parsed metadata is rendered on the called original image. The rendering result is output in such a manner that a graphic object 421 representing the zoom area 401 'is displayed in the original image 402, as shown in FIG. 4 (b).

At this time, a time line 423 indicating the time of zoom photographing may be displayed in one area of the original image 402, for example, below the zoom area 401 '.

The timeline 423 displays an object indicating the time at which it was photographed, which may be displayed at a corresponding location on the timeline 423. For example, referring to FIG. 4 (b), an image object displayed in black is displayed in the zoom photographed section.

On the other hand, a section in which zoom photographing is not performed can be displayed in white. In addition, the length of the image object is proportional to the time of the zoom photographed section, and the interval of the plurality of image objects may be displayed in proportion to the zoom photographed interval. For example, in FIG. 4 (b), it is confirmed that the zoom-in / zoom-out is repeated three times each.

In addition, although not shown, the color of the image object may be displayed differently so that the user can roughly know the degree of zoom.

In addition, a moving element (original image) indicating the reproduction time point of the current original image can be displayed on the time line 423, and the moving element can be immediately moved to the original image at a desired editing time by touching and dragging. That is, the time line 423 not only provides the zoom-related information in the entire original image, but also helps the user to quickly search the editing time or editing section of the original image.

Further, one or more function icons 424 may be provided in another area in the original image 402, for example, at the bottom. The function icon 424 may execute an instruction to save or cancel the edited zoom image.

For example, when a touch input applied to one point or a plurality of points of the graphic object 421 displayed on the original image 402 is dragged, the size of the displayed graphic object 421 is changed.

Meanwhile, although not shown, when a touch is applied to one point or a plurality of points of the graphic object 421, a guide object that guides the draggable direction may appear at one of the touched points. The control unit 180 changes the size of the zoom area matched to the first image to correspond to the changed graphic object.

For example, when a drag that pulls the edge of the graphic object 421 out of the zoom area is received, the size of the graphic object increases and the size of the zoom area also increases. On the other hand, when a drag to push the edge of the graphic object 421 toward the inside of the zoom area is received, the size of the graphic object is reduced and the size of the zoom area is also reduced. At this time, there is no influence on the display of the original image visually, and only the graphic object superimposed on the original image is varied.

In one example, if there is a plurality of zoom photographing sections in one original file, the editing result obtained in one zoom photographing section using the time line can be simultaneously applied to the entire zoom photographing section or a part of the zoom photographing section .

Specifically, if the second touch is applied to another zoom shooting interval of the time line 423 while maintaining the first touch applied to the original image subjected to the zooming operation after the zoom editing, the controller 180 displays the second touch It is possible to immediately change the zoom-related information at the zoom shooting time point in the metadata so that the zoom editing is applied to the corresponding zoom shooting interval as well. In this manner, the same zoom editing can be quickly applied to the entire zoom range or selected sections.

Meanwhile, in one example, zoom application may be canceled when the variable degree of the changed graphic object exceeds a threshold according to a touch input applied to the graphic object. For example, as shown in FIG. 4C, when the graphic object 422 is enlarged to the entire area of the original image and the user selects the storage icon 424, the zoom application may be canceled. It can be said that the metadata is updated with the zoom magnification of '1'.

As described above, zoom editing can be performed without being affected by the zoom photographed region by performing zoom editing on the original image that has been zoomed out. In addition, in the present invention, the graphic object displayed on the original image can be moved or varied through the touch gesture, so that the zoom area can be edited easily and quickly.

Next, FIG. 5 shows an example of generating a zoom image around a specific object in the edit mode. 5, when the pre-stored zoom image 501 is displayed on the touch screen 151 and the editing mode related thereto is executed, the original image 502 of the zoom image 501 is displayed as shown in FIG. 5B .

In the original image 502, a graphic object 521 representing a zoom area is displayed. In the present invention, editing of a zoom area may be performed in a manner that moves the graphic object 521 displayed on the original image. One or more objects may be included in the graphic object 521, Can be selected.

Specifically, when a long-touch is applied to a specific object 511 included in the graphic object 521, the control unit 180 can recognize and extract the selected object. Here, a specific object means a person, an animal, a moving object, and the like.

A guide object 521s separated from the background image may be displayed around the selected object 511, for example, as shown in FIG. 5C. Also, when a specific object is selected, the controller 180 may track a moving direction and a moving trajectory of a specific object.

For this, the control unit 180 can extract and recognize a moving object in the moving picture by calling a predetermined object recognition algorithm stored in the memory 170 of the mobile terminal 100. [

The object recognition algorithm is implemented using OpenCV (Open Computer Vision), facial recognition system, speaker recognition, FERET (Facial Recognition Technology), AAM (Active Appearance Model) But is not limited thereto.

On the other hand, when the original image is reproduced in the edit mode, the position of the image object 522 is automatically adjusted so that the selected object 511 is located at the center of the zoom area. That is, the graphic object corresponding to the zoom area is moved based on the tracking of the recognized object.

Thereafter, when the storage icon 523 is touched, the controller 151 stores the information related to the selected object 511 in the area where the zoom-related information is stored. Here, the information related to the selected object 511 refers to information such as a position, a moving direction, a moving speed, and a moving trajectory of the object 511 in the zoom shooting interval.

On the other hand, only the center area of the image has been enlarged before the zoom photographing. Therefore, every time the zooming target moves, a shake of the image necessarily occurs when moving the device. However, as described above, when the zooming target is selected in the zoom editing and the zooming area is automatically changed, the position of the zooming area is moved according to the movement of the zooming object in the image. In addition, it is possible to acquire a desired object-oriented zoom image without a complicated procedure.

6A and 6B illustrate an example in which a moving image of a selected moving object is predicted to change a zoom area in advance to naturally reproduce a zoom image.

In FIG. 5, the position of the zoom area continuously varies with the selection of a subject in the graphic object in the edit mode. In this regard, FIGS. 6A and 6B illustrate a more natural zoom image by predicting the changing direction and the changing speed of the zoom area in consideration of the moving direction and the moving speed of the selected subject.

When the object-oriented zoom editing is performed, information related to the selected object such as the position, movement direction, moving speed, and movement trajectory of the selected object is stored in the memory area in which the zoom-related information is stored as metadata.

Accordingly, when the play mode is executed, the zoom-related information and the information related to the selected object are parsed together. At this time, it is possible to perform rendering by adjusting the time clock so that the position of the object matched with each zoom time of the zoom-related information is slightly ahead of the actual zoom time.

Alternatively, the rendering may be performed so that the center position of the object can be precisely adjusted by combining both the position of the object matched at each zoom time point and the preceding point. In this case, since the movement of the zoom area is slightly ahead of the movement of the object, for example, as shown in FIG. 6A, the center position of the zoom area will be maintained even if the subject 611 moves very quickly through the moving means. That is, it is possible to precisely locate the subject 611 in the center of the zoom image 601 by grasping how fast to move in the A direction and in which direction to move through the recording of the meta data.

On the other hand, although not shown, in the play mode, the object-centered zoom image and the object-centered sound can be extracted and output. To this end, the audio information captured by the microphone 122 at the time of shooting the zoom image can be taken in the range of the sound corresponding to the zoom-related information, i.e., centered on the selected object, and rendered to the original image. In another example, the zoom area corresponding to the graphic object may be set to the stoop range (or stoop area).

Next, FIG. 7 shows an example in which the edited zoom image is quickly checked in the edit mode from the edit mode to the full screen, and the screen returns quickly to the previous edit screen.

7, when the edit mode is executed while the zoom image 701 is being displayed, a graphic object 721 indicating a zoom area together with the original image 702 is displayed.

When the zoom area is reduced along the drag path of the drag-touch input applied to the graphic object 721, the expanded zoom magnification is stored as meta data. At this time, if a touch (e.g., short-touch) is applied to an arbitrary point in the graphic object 721 before the storage icon 722 is touched, the edited zoom image is displayed on the full screen Can be confirmed.

For example, in FIG. 7B, a zoom-in operation is performed on the graphic object 721 by performing a pinch-in gesture, and then a touch is applied to the graphic object 721 reduced in size in the direction A, The preview image 703 of the zoomed image can be confirmed quickly.

7 (b), a pinch-out gesture is performed on the graphic object 721 to increase the zoom area, and then a touch is applied to the graphic object 721 increased in size in the direction B, Edited preview image 704 rather than being zoomed out or past.

After the preview images 703 and 704 are checked in this manner, when a touch is applied to an arbitrary point of the preview images 703 and 704, a previous edit state, for example, a screen shown in FIG. 7B I.e., the graphic object 721, can be immediately switched to the previous screen displayed. In this case, the user can quickly confirm the edited zoom image, and then perform zoom editing additionally.

In this way, since the edited zoom image can be confirmed in advance without exiting the edit mode, the troublesome operation is eliminated even if zoom editing is repeated many times.

In addition, in one example, a plurality of guide objects may be displayed in the original image, separately from the graphic object corresponding to the zoom area in the original image, though not shown. For example, if a first touch is applied to an arbitrary point of a graphic object or a proximity touch is detected, variable zoom regions can be recommended through a plurality of guide objects. At this time, the plurality of guide objects can be displayed based on the position of the object included in the original image and the taken zoom area.

Meanwhile, in the present invention, zoom related information (at least one of the position, size, and magnification of the zoom area) of the image can be automatically changed while an event is detected in the zoom image. In this case, the event can be restored to have the original zoom related information if it is no longer detected.

Here, the detection of the event may include detection of information included in the zoom image, for example, detection or non-detection of a specific object, detection of a specific sound, or generation of another zoom image And the like.

Hereinafter, an example will be described with reference to FIG. 8, in which an object is not included when the zoom magnification of the image is automatically changed so that a desired object is included in the zoom image (detection of an event).

8A, when the central object 811 detects that the specific object (e.g., an animal) 812 is blocked for a predetermined time during playback of the zoom image 801, It is possible to control the automatic zoom magnification adjustment by executing the weaning mode. Particularly, as the editing mode is executed, a part of the center subject 811 and the removal target 812 in the graphic object 821 can be displayed in the original image 802.

At this time, if a predetermined touch gesture (e.g., long touch input or double-short touch input) is applied to the removal object 812, the object 812 is recognized and extracted from the background image, Information may be displayed around the object 812. [

For example, while the select box image is displayed on the object 812, a 'remove' icon 822 may be displayed around the object. When the user touches the removal icon 822, the zoom magnification is enlarged around the center subject 803 so as not to be included in the zoom image while the object 812 is located within the zoom area.

The control unit 180 may modify the zoom-related information so that magnification is enlarged while the removal object 812 to be included in the zoom image is included in the original zoom region.

The control unit 180 recognizes the start point and the end point of the removal target 812 in the original zoom area and then changes the zoom point in consideration of the position and size of the removal target 812 during the corresponding period t1. The magnification can be determined. Accordingly, when the corresponding section is reproduced, the extended zoom image 803 can be displayed as shown in FIG. 8 (c).

Thereafter, if the removal object 812 is completely deviated from the original zoom area, it can be automatically adjusted to the original zoom magnification. As a result, the original zoom image 801 is displayed as shown in (d) of FIG. That is, the zoom-related information is applied only to a certain portion within the zoom period, and if the object to be removed 812 is no longer detected within the zoom area, it is restored to the original zoom-related information.

In addition, when the information related to the object to be removed is stored together with the metadata, if the object to be removed appears again in the zoom area, the zoom image can be configured so that the object to be removed is not included in the zoom image by adjusting the zoom magnification by itself . On the other hand, such setting of the removal target may be released in the edit mode.

In this case, the original zoom image can be easily restored to the original zoom image only by a touch input that removes the select box image displayed on the original image. In preparation for such reediting, the metadata corresponding to the zoom-related information and the metadata related to the removal target may be separately generated and stored.

FIG. 9 shows an example of generating a customized zoom image by simultaneously selecting an object to be included in the zoom image and an object to be excluded in the edit mode.

9, when a plurality of subjects are displayed at a time in the original image 902 as shown in FIG. 9B as the editing mode of the zoom image 901 is executed, the user can use the touch gesture to zoom in the zoom area 921 and the object 912 to be excluded from the zoom area 921, respectively. This can be performed by changing the manner, number of times, and degree of touch of the touch input to the objects 912 and 913.

An 'include' icon 923 may be displayed around the object 913 to be included in the zoom area 921 and a 'remove' icon 922 may be displayed around the object 912 to be excluded from the zoom area 921 Can be displayed.

Next, when the storage icon 924 is touched, the information related to the object to be added and the information related to the object to be excluded can be recorded together with the existing metadata with the zoom-related information. Then, in the playback mode, all of the above information are simultaneously parsed, and a customized zoom image is displayed.

Therefore, in the zoom image to be displayed, the position of the added object and the position of the excluded object are simultaneously considered, and the position and magnification of the zoom area are automatically changed. Thereby, the zoom images 903 and 904 in which the zoom area is automatically changed are displayed.

As described above, since the object to be added and the object to be removed can be selected together in the zoom image in one editing screen, the usability and efficiency of zoom editing are further improved.

10 is a representative flowchart for explaining an operation related to storing and managing an original image and zoom-related information separately in a zoom photographing in a mobile terminal according to the present invention.

First, the camera 122 provided in the mobile terminal 100 is activated for capturing an image. During shooting of a video, a zoom shooting command may be received (S1010).

For example, a pinch-out gesture may be performed on a preview image being photographed to generate a zoom photographing command. Here, the pinch-out gesture may be a gesture for simultaneously dragging a plurality of touch points within an area to be zoomed in on the touch screen 151 in directions away from each other. When the zoom photographing instruction is received in this way, the preview image being photographed is changed to the zoom image.

In the present invention, even when the preview image is switched to the zoom image, the entire original image without zooming is captured and stored. Specifically, the original image is stored in the first memory area, and the related information corresponding to the received zoom photographing command is stored in the second memory area different from the first memory area (S1020).

Here, there is no particular limitation on the first memory area in which the original image is stored and managed. Also, the second memory area may be, for example, an XMP custom metadata area, and the zoom-related information may be XMP metadata including, for example, a zoom area size, a position, and a zoom shooting time. Since the XMP metadata is not the header information of the original file, even if the metadata is removed, added, changed or overwritten, there is no influence on the reproduction of the image.

Then, when a play mode is executed (S1030), the zoom-related information stored in the second memory area is parsed and rendered on the original image stored in the first memory area. Accordingly, the second image zoomed in from the original image is displayed (S1040).

As described above, when the edit mode of the zoom shot image is executed, the zoom-related information stored in the second memory area is parsed and rendered to the original image, May be displayed.

Further, in the embodiment of the present invention, when the zoom-related information is changed in the above-described edit mode, the controller 180 stores only zoom related information stored in the second memory area while maintaining the original stored in the first memory area Update. At this time, the zoom-related information before editing is automatically deleted.

Thereafter, when a play mode is executed, a second image matched with the zoom-related information parsed at the playback time is displayed, and the first image shot before the editing is disappeared unless stored by the user. As described above, since the first image, the second image, and the third image are not stored in proportion to the number of times of editing, only the metadata is changed, so that the memory space is not unnecessarily occupied.

As described above, the mobile terminal according to the embodiment of the present invention can access the original file of the zoomed-in image while maintaining the UI / UX related to the zoom shooting, and can edit the position and size of the zoom area without restriction The efficiency of shooting and editing of the zoom image is increased. In addition, by allowing the zoom region to move along with the movement of the selected specific object, the quality of the zoomed-in image is improved and the user is provided with convenience. Also, it is possible to quickly check the changed zoom image even in the edit mode. Further, by storing and managing the original file and the zoom-related information in a separate memory area, even if the editing and the reproduction are repeated many times, the user can edit it as desired regardless of the previous editing contents.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
