In this case, the power supply unit 190 uses one or more of an inductive coupling method based on a magnetic induction phenomenon from an external wireless power transmission device or a magnetic resonance coupling method based on an electromagnetic resonance phenomenon. Power can be delivered.

Meanwhile, various embodiments below may be implemented in a recording medium readable by a computer or a similar device using, for example, software, hardware, or a combination thereof.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal configured as described above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential features of the present invention.

2 is a flowchart illustrating a control method for easily attaching image data captured through a camera according to an embodiment of the present invention. 3 is a diagram showing a state diagram of a control method for easily attaching image data captured through a camera according to an embodiment of the present invention. Hereinafter, it will be described with reference to FIGS. 2 and 3 together.

In S201, the controller 180 outputs an execution screen of a predetermined application through a touch screen. In FIG. 3 (a), the mobile terminal 100 is an example of the execution screen, and outputs an execution screen of a social network service (SNS) application (hereinafter, a message transmission / reception application) capable of transmitting and receiving a message. The message transmission / reception application is an application that can transmit and receive text, image, and / or voice data with at least one receiving counterpart, and can transmit and receive such data using the wireless communication unit 110.

More specifically, the execution screen of the message transmission / reception application (example) will be described with reference to the execution state diagram of FIG. 3 (a). In the example shown in FIG. 3, the user of the mobile terminal 100 is in a state of transmitting and receiving a message with a counterpart terminal called "Jane". This execution screen includes a transmission / reception recording area 300 in which messages that have already been transmitted and received are output. Referring to the transmission / reception recording area 300, the left-aligned messages 302-1 are messages (hereinafter, received messages) received by the mobile terminal 100 from the other terminal, and the right-aligned messages 301-1 to 301 -3) These are messages (hereinafter, transmission messages) that the mobile terminal 100 has transmitted to the other terminal. Hereinafter, in the execution screen of the message transmission / reception application to be described in the detailed description of the present invention, the transmission messages are displayed as 301-1, 301-2, ..., and the received messages are 302-1, 302-2, ... It is indicated by.

In step S202, the controller 180 may display a preview screen of the camera in one area of the output execution screen. Referring to Figure 3 (b), this preview screen is output in the form of a pop-up window (303, hereinafter, a preview pop-up window). In this case, the preview pop-up window 303 is output to an area on the execution screen of the predetermined application.

The preview pop-up window 303 in one embodiment of the present invention is always floating on the touch screen 151, regardless of the output of the execution screen of another application, as always (Floating pup-up window). It is suggested to be printed. For example, the physical layer that controls the output of the preview pop-up window 303 is proposed to be implemented in a framework stage rather than an application stage. Accordingly, even when the preview pop-up window 303 is floating, the execution screen of another application can operate (output information and / or input a touch gesture, etc.) regardless of the output of the preview pop-up window 303. .

In one embodiment of the present invention, a method for easily attaching image data on a predetermined application is proposed. In general, in order to attach image data on a predetermined application, when a camera activation command is received, it is output by switching to a camera preview screen while outputting an execution screen of the application. Then, after taking the picture, it is switched back to the execution screen of the application that was originally output, and the captured image data is attached. In this process, the application that was running before the camera activation may be executed in the background for a while, or the output of the execution screen may be temporarily stopped.

Therefore, in detail, in one embodiment of the present invention, it is proposed to output the preview screen of the camera in one area of the execution screen while outputting the execution screen of the existing output application as it is. Further, when a predetermined command is received, it is proposed to take an image through the camera and attach the captured image data directly to the application.

In step S203, the controller 180 waits to receive the attachment command from the user. The attach command means a command received from a user who photographs an image through an activated camera and attaches the captured image data directly to an application. In step S203, if no attachment command is received, the controller 180 may return to step S202. In step S203, when an attachment command is received, the controller 180 proceeds to step S204.

In step S204, the controller 180 may attach the image data captured through the camera on the predetermined application.

Furthermore, the controller 180 in one embodiment of the present invention may control the wireless communication unit 110 to immediately transmit the attached image data when the predetermined application is a message transmission / reception application. That is, according to this embodiment, when the user wants to transmit the captured image data to the other party receiving the message, the user can easily and easily attach and transmit the image using the attach command once (attached immediately).

Since the image data taken directly through the camera is attached, it can be attached without confirming the image data captured by the user (in a message sending / receiving application, it is attached and transmitted). In such a case, especially in a message transmission / reception application, even if unwanted image data is captured, the image data may already be attached (transmitted). Therefore, in step S204 according to another embodiment of the present invention, in response to receiving an attachment command, after outputting a pop-up window confirming whether to transmit the captured image data, inputting a command confirming whether the user attaches through the pop-up window It is suggested to attach the captured image data. And, if you do not want to send the captured image data, you will be able to cancel through the pop-up window (attached after confirmation).

The controller 180 according to an embodiment of the present invention may combine the above two embodiments to distinguish the operation of "attaching immediately" and the operation of "attaching after confirmation" through a user command. That is, when the first command is received, the controller 180 can immediately attach the captured image data to the application after shooting through the camera. Then, when the second command is received, the controller 180 outputs a pop-up window for attaching image data captured through the camera, and when a confirmation command is received through the output pop-up window, the captured image data can be attached to the application. have. As an example of the first command, a double touch (two short touches within a predetermined time) received on the preview pop-up window 303 and an example of the second command include a short touch received on the preview pop-up window 303. have.

On the other hand, in one embodiment of the present invention, in performing the attach operation in step S204, it is proposed to change the size of the image data to be attached (data size) based on the size of the preview pop-up window 303. Hereinafter, with reference to FIG. 7, the controller 180 may change the size of the preview pop-up window 303 in response to a user command or a predetermined condition. When the size of the preview pop-up window 303 is the first size in response to receiving the attachment command, the controller 180 converts the data size of the image data to be attached to the first data size, and previews it. When the size of the pop-up window 303 is the second size, the data size of the image data to be attached may be converted to the second data size.

3 (c) shows an execution screen to which the captured image data is attached. Referring to FIG. 3 (c), the attached image data is transmitted, and the transmission message 301-4 with the image data attached to the transmission / reception recording area 300 is displayed.

Meanwhile, in the above-described embodiment, the message transmission / reception application is described as an example, but is not limited to this example and may be applicable to various types of applications. In particular, an embodiment of the present invention may be applicable to an application in which a copy operation on image data is possible and a paste operation on copied image data is possible.

In addition to the example of the above-described application, specifically, an example of an application to which an embodiment of the present invention is applicable is as follows.

(1) Address book (or contact) application-When an attachment command is received on the address book application, the controller 180 can take a picture and directly attach the captured image data as an image on a predetermined address book (or contact) item. . Alternatively, when a predetermined face is included in the image data photographed on the address book (or contact) application, the controller 180 may search the address book based on the identified face and provide it to the user.

(2) Map application-When an attachment command is received on the map application, the controller 180 may take a picture and store image data of the captured picture as image data corresponding to a predetermined location on the map. In this case, the image data corresponding to a predetermined location refers to an image displayed in a pin shape at a predetermined location when the user later views the corresponding map again.

(3) E-mail application-As in the message transmission / reception application, the controller 180 may attach the captured image data to an e-mail written to the receiving counterpart.

(4) Video playback application-When an attach command is received during video playback, the controller 180 may attach (store) the captured image data in the form of clip image data for the playback time.

(5) Gallery application-When an attachment command is received, the controller 180 can control the captured image data to be stored in the corresponding gallery application. In particular, when the storage structure of the image data is stored in a folder form in the gallery application, when an attachment command is received from the folder, the controller 180 may change the storage path so that the captured image data is stored in the folder. Alternatively, when an attachment command is received, the controller 180 may search for an image in the gallery application using the captured image data and provide the search result. In this case, if a face is included in the captured image data, an image including the corresponding face may be searched, or a location information on which the corresponding image data was captured may be searched.

(6) Memo application-When an attach command is received, the controller 180 can take a picture through the camera and directly attach the image data of the captured picture on the memo application. The attached image data can be deleted by inputting a key button (backspace button) for erasing a character, as if it were treated as one text.

(7) Calendar application-When an attachment command is received, the controller 180 may take a picture through the camera and add image data of the captured picture to the schedule.

(8) Music playback application-When an attachment command is received, the controller 180 can set a cover photo of the currently played music. Alternatively, when the album image included in the image data of the photographed picture is recognized, music and / or album may be searched using the recognized album image.

(9) Search application (or when accessing a search site on a web browsing application)-When an attach command is received, the controller 180 attaches the image data of the photographed picture to the search application and uses the attached image data It can be controlled to search.

(10) Other application-When an attachment command is received, a pop-up for sharing image data of the photographed picture may be output.

Meanwhile, in step S202, the controller 180 outputs a preview pop-up window 303 of the camera. The preview pop-up window 303 may be output by the controller 180 under a predetermined condition, but in one embodiment of the present invention, it is proposed to be output by a user command. An example of a user command for outputting the preview pop-up window 303 will be described with reference to FIGS. 4 and 5.

4 and 5 are diagrams illustrating examples of user commands for outputting a camera preview pop-up window 303 according to an embodiment of the present invention.

Fig. 4 (a) shows a state diagram displaying a home screen. I will elaborate on the home screen. In general, the home screen may be defined as a screen displayed on the touch screen 151 for the first time when the lock state of the touch screen 151 is released, and one or more icons for executing an application or an internal function, or The widget may be displayed. The mobile terminal 100 may have one or more home screens, and in this case, when a predetermined touch gesture is performed on the touch screen 151, the two or more home screens may be sequentially displayed one by one. Different icons (widgets) may be disposed on each of the home screens. The controller 180 according to an embodiment of the present invention outputs an icon (401, hereinafter, a quick shooting icon) for outputting a camera preview pop-up window 303 on a home screen screen, and the quick shooting icon 401 A preview pop-up window 303 may be output in response to the selected input 10a.

Meanwhile, according to the above-described method, it is not easy to output the preview pop-up window 303 while outputting the execution screen of the application. This is because, during the execution screen of the application, after switching the screen to the home screen again, the quick shooting icon 401 must be selected. Accordingly, in another embodiment of the present invention, a control method capable of outputting the preview pop-up window 303 on the execution screen of the application is further proposed. This embodiment will be described with reference to FIG. 5.

Referring to FIG. 5 (a), the controller 180 outputs an execution screen of a text message transmission application through the touch screen 151.
