Hereinafter, embodiments related to the terminal configured as above will be described with reference to the accompanying drawings. The following embodiments can be used alone or in combination with each other. In addition, the embodiments described below may be used in combination with the above-described user interface (UI).

Embodiments disclosed in this document can be implemented in the mobile terminal 100 described with reference to Figs. 1 to 2B.

Hereinafter, the operation control method of the mobile terminal and the operation of the mobile terminal 100 for implementing the same will be described in detail with reference to FIGS. 3 to 8B.

3 is a diagram illustrating a process of controlling an operation of a mobile terminal according to an embodiment of the present invention.

First, the control unit 180 determines whether the preview function of the camera 121 is activated. For example, if the camera application is selected and executed through the user input unit 130, the preview function of the camera 121 can be activated. Alternatively, the preview function of the camera 121 is activated in response to a request of the application in which the application utilizing the preview function of the camera 121 is executed, among the applications stored in the memory 160.

When the preview function of the camera 121 is activated, the controller 180 can obtain current position information and direction information of the mobile terminal 100 (S100). For example, the control unit 180 receives the current coordinate information of the mobile terminal 100 from the repeater through the mobile communication module 112, or receives the current coordinates of the mobile terminal 100 from the satellite through the position information module 115 Information can be received. In addition, the controller 180 may acquire the direction information of the mobile terminal 100 through the sensing unit 140. For this, the sensing unit 140 may include a direction sensor. As the direction detecting sensor, for example, a geomagnetic sensor may be used. The geomagnetic sensor can detect the azimuth of the mobile terminal 100 using magnetic field information horizontally formed on the surface of the earth.

When the location information and the direction information of the mobile terminal 100 are obtained, the controller 180 may obtain a map image corresponding to the current location information and the direction information of the mobile terminal 100 in the live map (S200). Here, the real map can be, for example, a map including an image photographed through a camera capable of acquiring an image of a point (for example, 360 degrees) at one point. The live-action map can be stored in the server or in the memory 160. [ The live-action map may include body data including meta data including position information and direction information of each image as indices, and actually captured images. When the controller 180 requests the output (or transmission) of an image corresponding to the specific positional information and the directional information, the server or memory 160 storing the realistic map searches the metadata of the realistic map and outputs the corresponding image (Or transmitted).

In one embodiment, the controller 180 may adjust the size of the map image according to the position information and the direction information according to the size of the preview image. Accordingly, the sizes of the map images displayed on the screen of the mobile terminal 100 overlapping the preview image and the preview image may be the same, and the preview image and the map image may be displayed with the same size for the same object.

When the map image is acquired according to the location information and the direction information of the mobile terminal 100, the controller 180 may determine the transparency of the acquired map image (S300). For example, the transparency of the map image may be input through the user input unit 130. The control unit 180 can check the transparency of the map image input through the user input unit 130. [

When the transparency of the map image is determined, the controller 180 may display the map image on the screen through the display unit 151 so as to overlap the preview image photographed through the camera 121 according to the transparency of the determined map image ( S400). For example, when the transparency of the map image determined in operation 300 is 100, the controller 180 may display only the preview image on the screen. Also, when the transparency of the map image determined in operation 300 is 50, the controller 180 may adjust the transparency of the map image to 50 and display it on the screen. Also, the controller 180 may display only the map image on the screen when the transparency of the map image determined in operation 300 is zero. Accordingly, the map image and the preview image can be superimposed on the screen according to the transparency of the map image on the screen of the mobile terminal 100.

4A to 4C are conceptual diagrams showing a screen of a mobile terminal for displaying a live-action map image in a preview image according to the first embodiment of the present invention.

Referring to FIG. 4A, when the preview function of the camera 121 is activated, the preview image 210 may be displayed on the screen 200 of the mobile terminal 100. The user interface element 201 for selecting the transparency of the map image corresponding to the current location information and the direction information of the mobile terminal 100 may be displayed on the screen 200 of the mobile terminal 100. [ The user interface element 201 may initially display a value of transparency of 100. In this case, the preview image 210 may be displayed on the screen 200 of the mobile terminal 100, and the map image may not be displayed. On the contrary, the user interface element 201 may initially display a value of transparency of 0, in which case the map image is displayed on the screen 200 of the mobile terminal 100, and the preview image 210 is not displayed .

Referring to FIG. 4B, a user may adjust the transparency of the map image 220 through the user interface element 201. Accordingly, when the transparency of the map image 220 is determined to be one of the values at 0 and the preview image 210 is displayed on the screen 200 of the mobile terminal 100 as it is, May be superimposed on the preview image 210 on the screen 200 of the mobile terminal. Accordingly, the user can compare the preview image 210 and the map image 220 corresponding to the current position and direction by adjusting the transparency of the map image 220.

For example, when the user input unit 130 receives the drag input moving from the left to the right through the user interface element 201, the controller 180 controls the movement of the mobile terminal 100 The map image 220 may be superimposed on the preview image 210 on the screen 200 of FIG.
