A waterproof structure (not shown) for sealing the rear case 102 and the rear cover 103 when the rear case 102 and the rear cover 103 are coupled to each other to prevent water from being injected into the external components.

In one embodiment of the present invention, the sensing unit 140 further includes a fingerprint recognition sensor. In recent years, many fingerprint recognition sensors have been introduced to improve security. That is, if the registered fingerprint of the user is recognized while the terminal is locked, the controller 180 can cancel the locked state of the terminal.

There is a need to study additional usage schemes (terminal control methods) rather than merely authenticating fingerprint recognition sensors used in such a manner. Therefore, in one embodiment of the present invention, a method of controlling a terminal through the fingerprint recognition sensor will be described.

A fingerprint of a person can be identified by the division of the left / right hand and the finger by finger, even if it is the same person. Therefore, in one embodiment of the present invention, it is proposed that the finger of the left hand / right hand of the user operates in a different operation mode (in particular, a photography mode).

The fingerprint recognition method of the fingerprint recognition sensor according to an embodiment of the present invention may be various methods. Specifically, a method of inputting a fingerprint through the scan unit may be applied if the scan unit of the fingerprint recognition sensor according to an embodiment of the present invention is fixed and the fingerprint is slid to a scan unit in which a user is fixed. Also, a method of inputting a fingerprint by scanning a recognition unit when a finger is placed on a recognition unit fixed to the fingerprint recognition sensor according to another embodiment of the present invention can be applied. Further, the fingerprint recognition sensor according to another embodiment of the present invention is provided in the entire area of the touch screen 151 or one area of the touch screen 151. When a touch is input to the touch screen 151, A fingerprint recognition method can be applied.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal configured as above will be described with reference to the accompanying drawings.

5 is a diagram showing an example of a method for automatically setting a security for a photographed image according to an embodiment of the present invention. 6 is a diagram showing a flowchart of a method of automatically setting security on a photographed image according to an embodiment of the present invention. Hereinafter, the conceptual diagram of Fig. 5 and the flowchart of Fig. 6 will be described together.

5A, the controller 180 activates the camera 121 and displays a preview screen of the activated camera 121 on the display unit 151 (step S601 in FIG. 6) ). The shutter-key for photographing through the camera 121 is realized by a virtual shutter button 501 (hereinafter referred to as a shutter button) displayed on the touch screen as shown in Fig. 5 (a) Or may be implemented by a hardware button provided on the outer surface of the mobile terminal 100. [

5A, when the shutter button 501 is selected (step S603), the control unit 180 photographs the photograph through the camera 121 (step S604) The image data for the photograph may be stored in the memory 160 (step S605). The stored image data can be browsed through a gallery application (or a captured image viewing function of a camera shooting application).

The image data stored by the above method is image data for which security is not set. Here, the meaning that the security is not set means that the user can browse the mobile terminal 100 regardless of the user who uses the mobile terminal 100. That is, when the gallery application of the mobile terminal 100 is executed, the image data can be browsed by anyone.

In the case of image data, there is a need to improve the security because the association with the privacy of a specific individual is high. Accordingly, an embodiment of the present invention proposes a control method for simplifying the security setting on such image data. That is, in one embodiment of the present invention, specifically, a general photographing mode and a security photographing mode are distinguished from each other, and in order to store photographs photographed in the security photographing mode, automatic security setting is proposed. The picture taken in the normal shooting mode means the same shooting mode as the conventional shooting mode.

In the embodiment of the present invention, when a predetermined fingerprint is recognized through the fingerprint recognition sensor in the state where the camera 121 is activated (step S602), the control unit 180 stores the recognized fingerprint It is proposed to secure the fingerprint and save it (security shooting mode). The operation of securing with a predetermined fingerprint according to an embodiment of the present invention means that a predetermined fingerprint is needed in browsing the securely stored photograph. That is, although it is necessary to recognize a predetermined fingerprint, it means that the corresponding photograph can be browsed.

5B is a view showing a state in which a predetermined fingerprint is recognized in a state where the camera 121 is activated. The control unit 180 includes a security indicator 502 indicating that the photographed image is securely stored It can be displayed together with the photo preview screen. 5B, the control unit 180 captures a picture (Step S607), secures the captured picture and stores it in the memory 160 (Step S608) can do. In this case, the security can be secured based on the predetermined fingerprint in the security. For example, the secured photograph can be set to be viewed only by the predetermined fingerprint. A method for browsing secured pictures will be described below with reference to FIGS. 7 and 8. FIG.

In the embodiment described with reference to FIG. 5, a case is described in which a fingerprint is recognized on a camera preview screen and then a photograph is taken. However, the relationship between fingerprint recognition and photographing is not limited. That is, even if the fingerprint recognition is performed after the photographing is performed first, the embodiment of FIG. 5 may be similarly applied. 5 (a), when the recognition of a predetermined fingerprint is detected after the camera 121 is activated and the photograph is taken, the control unit 180 displays a security function . In the embodiments to be described below, recognition of the fingerprint and the photographing tube will not be limited to the subsequent relationship.

7 is a diagram showing a method for browsing a secured picture according to an embodiment of the present invention. 8 is a flowchart showing a method of browsing a secured picture according to an embodiment of the present invention. Hereinafter, FIG. 7 and FIG. 8 will be described together.

In step S801, when the gallery application (or an application that can browse other image data) is executed, the control unit 180 displays a preview thumbnail (or image data) of at least one image data stored in the memory 160 (See Fig. 7 (a)).

In an embodiment of the present invention, it is proposed to display image data of a photograph secured by a predetermined fingerprint on one folder 701 (hereinafter referred to as a security folder) as shown in FIG. 7A (step S802). The control unit 180 may further display a security indicator 702 in the displayed security folder, which indicates that the data is secured.

7B, the control unit 180 displays a pop-up window 703 for requesting the user to recognize the fingerprint on the display unit 151 (step S803) And can wait for the fingerprint to be recognized. If the fingerprint is recognized, the controller 180 determines whether the recognized fingerprint matches a predetermined fingerprint corresponding to the selected security folder (i.e., a predetermined fingerprint entered when entering the secure shooting mode) (step S805). If it is determined that they match, the controller 180 may proceed to step S806. That is, when it is determined that the predetermined fingerprints match, the controller 180 displays a preview thumbnail of the content (image data) included in the secure folder 701 to the user, as shown in FIG. 7C (Step S806). If they do not match, the control unit 180 displays a pop-up window 703 for requesting the user to recognize the fingerprint on the display unit 151 and waits for the fingerprint to be recognized.

Further, in an embodiment of the present invention, it is possible to enter a secure shooting mode for each of a plurality of fingerprints of a user's finger, and proposes to generate a security folder for each. Each security shooting mode and security folder will be the same as in the above-described embodiment.

If any one of the thumbnails is selected (step S807), the control unit 180 may control to display the image data corresponding to the selected thumbnail (step S808).

As shown in FIG. 7 (c), it is possible to set the security again in a state where the security is released and the image data can be browsed. In the state of Fig. 7 (c), once the predetermined fingerprint is recognized, the control unit 180 suggests setting the security again for the folder. According to another embodiment of the present invention, a fingerprint input is requested to the user only when the user enters the browse screen of the folder. After entering the browse screen of the folder, the user exits the browse screen of the folder again, It is suggested that the security setting be canceled before the end of the security setting.

So far, we have seen how to set security on photos taken in secure capture mode, and how to view secured image data. In another embodiment of the present invention, a method of sorting / filtering image data using a fingerprint sensor is further proposed. Such an embodiment will be described with reference to Figs. 9 and 10. Fig.

FIG. 9 is a diagram illustrating a method of sorting the displayed thumbnails according to an alignment condition corresponding to a predetermined fingerprint when a predetermined fingerprint is recognized while a preview thumbnail of image data is displayed according to an embodiment of the present invention. FIG.

As shown in FIG. 9A, the controller 180 may display a preview thumbnail for at least one image data using a predetermined application. In this case, the preview thumbnail may include not only a preview thumbnail for one image, but also a thumbnail for a folder displaying a plurality of image data in one group.

In this state, when a predetermined fingerprint is recognized through the fingerprint recognition sensor, the control unit 180 can sort the displayed thumbnail using the alignment condition corresponding to the predetermined fingerprint.

That is, when the first fingerprint is recognized, the control unit 180 can arrange the thumbnail in the first condition (see FIG. 9 (b)). Further, when the second fingerprint is recognized, the control unit 180 can arrange the thumbnail in the second condition (see Fig. 9 (c)).

The sorting condition may include at least one of the shooting date and time sequence, the alphabetical order, the alphabetical order, and the frequency of viewing.

FIG. 10 illustrates a method of filtering the displayed thumbnail in accordance with a filtering condition corresponding to a predetermined fingerprint when a predetermined fingerprint is recognized while a preview thumbnail of image data is displayed according to an embodiment of the present invention. FIG.

As shown in FIG. 10 (a), the controller 180 may display a preview thumbnail for at least one image data using a predetermined application.

10 (a), when the predetermined fingerprint is recognized through the fingerprint recognition sensor, the controller 180 filters the displayed thumbnail using the filtering condition corresponding to the predetermined fingerprint (FIG. 10 b) and (d)), and generate filtering result folders 1001a and 1001b including filtering results. In this case, the filtering condition may include at least one of a predetermined tag search word, an image data format, and a face recognition result for a predetermined person.

For example, when the first filtering condition corresponding to the first fingerprint recognition is a 'Brad pitt' tag search word, the control unit 180 determines that the image data stored in the memory 160 The first filtered result folder 1001a including at least one piece of image data that is searched can be generated.

When the second fingerprint is recognized, filtering may be performed on the basis of the second filtering condition and the second filtering result folder 1001b may be displayed as in the first fingerprint recognition.

Furthermore, in one embodiment of the present invention, the control unit 180 recognizes not only the tag search word but also the face of the person included in the image data, and recognizes the face image of the 'Brad pitt' Can be further searched.

And, in another embodiment of the present invention, the control unit 180 can operate to store the facial recognition result of the image data together with the tag. That is, when the facial recognition result included in the image data includes the face of a predetermined person (for example, 'Brad pitt' person), the control unit 180 displays the name of a predetermined person and / The face recognition result (for example, 'Brad pitt') can be stored in association with tag information. In this case, the control unit 180 can search for a person included in the image data only by searching for a tag for a specific person.

Meanwhile, in one embodiment of the present invention, in addition to the above-described photographing mode, a shared photographing mode is further proposed. The shared shooting mode means a shooting mode in which a photographed image can be directly shared through a sharing method corresponding to a predetermined fingerprint (for example, using a specific social network service SNS). Such an embodiment will be described below with reference to Figs. 11A to 11C.

11A to 11C are diagrams showing a method of entering a shared shooting mode and taking a picture in a shared shooting mode, according to an embodiment of the present invention.

Referring to FIG. 11A, the control unit 180 activates the camera 121 and displays a preview screen of the activated camera 121. FIG. In this state, when a predetermined fingerprint (the first fingerprint in the example of FIG. 11A) is recognized, the control unit 180 can enter the shared shooting mode (see FIG. 11A). When entering the shared shooting mode, the control unit 180 may further display a first sharing indicator 1101 indicating a sharing method corresponding to the inputted predetermined fingerprint. The first shared indicator 1101 indicates a method of sharing using a predetermined SNS (Social Network Service).

In the shared shooting mode, when a shooting command is received, the control unit 180 can take a picture and output a shared pop-up window 1102. [ The shared pop-up window 1102 is a pop-up window for creating a post corresponding to the input sharing method corresponding to the input fingerprint, and the control unit 180 may include a photograph taken in the shared pop-up window 1102 as an attached file . Therefore, the user can be provided with an environment that can be shared only by the photograph photographing command. When the creation of the post is completed, the control unit 180 can control to register the post using the "predetermined SNS ".

On the other hand, among the above-described embodiments, the embodiment described with reference to Fig. 5 can be applied independently of the embodiment shown in Fig. 11A, or may be applied together. For example, when the fingerprint of the index finger of the user is recognized, the user enters the secure shooting mode, and when the fingerprint of the user's stop finger is recognized, the user can operate to enter the shared shooting mode using the "predetermined SNS" .

Referring to FIG. 11B, the controller 180 activates the camera 121 and displays a preview screen of the activated camera 121. FIG. In this state, if the predetermined fingerprint (the second fingerprint in the example of FIG. 11B) is recognized, the control unit 180 can enter the shared shooting mode (see FIG. 11B). When entering the shared shooting mode, the control unit 180 may further display a second shared indicator 1104 indicating a sharing method corresponding to the inputted predetermined fingerprint. The second sharing indicator 1104 indicates a method of directly transmitting and sharing a picture to a predetermined contact. The predetermined contact may be a partner contact corresponding to the recognized second fingerprint.

In the shared photographing mode of Fig. 11B, when a photographing instruction is received, the control unit 180 can control photographing and sending the photographed photograph directly to the predetermined contact. Accordingly, the user can be provided with an environment in which a photograph can be easily shared with a predetermined other party only by taking a photograph. For example, when a contact of a lover is registered on an index finger, the user can easily transmit a photograph taken to his / her lover at the time of photographing. When the photographed picture is transmitted to a predetermined other party, the control unit 180 may further display a guide popup window 1105 indicating that the picture has been transmitted.

Meanwhile, when a plurality of fingerprints are simultaneously recognized, the embodiments described above in FIGS. 11A and 11B can be applied at the same time. This embodiment will be described with reference to FIG. 11C.

Referring to FIG. 11C (a), the controller 180 activates the camera 121 and displays a preview screen of the activated camera 121. FIG. In this state, if the predetermined fingerprint (the first fingerprint in the example of FIG. 11C) is recognized, the control unit 180 can enter the shared shooting mode using the "predetermined SNS" (see FIG. 11C (b)). Then, the control unit 180 can display the first sharing indicator 1101 corresponding to the shared shooting mode using the "predetermined SNS" (see FIG. 11C (b)).

When the predetermined fingerprint (second fingerprint in the example of FIG. 11C) is subsequently recognized, the control unit 180 can enter the shared shooting mode in which the control unit 180 transmits not only the "sharing through the predetermined SNS", but also directly to the predetermined contact (b)). That is, the embodiments of FIGS. 11A and 11B may be simultaneously applied. Then, the control unit 180 may display the second shared indicator 1104 corresponding to the predetermined contact with the first shared indicator 1101. [

FIG. 12 is a diagram illustrating a method of distinguishing a method of sharing image data that has been stored according to an embodiment of the present invention.

Referring to Fig. 12 (a), the control unit 180 reads predetermined image data through the gallery application. When the first fingerprint is recognized, the control unit 180 can share the image data with the predetermined "predetermined partner" (Figs. 12B and 12C). More specifically, when the first fingerprint is recognized, the control unit 180 can output a popup window asking whether to share the picture with the "predetermined counterpart" (Fig. 12 (b)). When the example (Y) is selected in the pop-up window, the control unit 180 may control the wireless communication unit 110 to transmit the image data being viewed to the predetermined other party.

When the second fingerprint is recognized, the control unit 180 can create a post including the image data through the previously set "predetermined application ". More specifically, when the second fingerprint is recognized, the control unit 180 may output a pop-up window asking whether to share the image data through the "predetermined application". When the user selects Y on the pop-up window, the control unit 180 includes the image data as an attachment file 1103 and creates a posting pop-up window 1102 that can be shared with other users through the application, Can be displayed.
