4 and 5 are screen state diagrams illustrating a process of controlling an operation of a specific object included in a preview image according to the present invention.

3 to 14, when a menu function for augmented reality is selected by a user, the controller 180 of the mobile terminal 100 drives the camera 121 and currently inputs through the camera 121. The preview image 300 of the area is displayed on the touch screen 151 [S110].

In addition, the controller 180 determines the current location of the mobile terminal 100 through the location information module 115 [S120]. That is, the location information module 115 receives location information including latitude, longitude, altitude and direction of the mobile terminal 100 from the satellite under the control of the controller 180.

Subsequently, the controller 180 can determine object information about one or more objects existing in the preview image 300 in the object information database in the memory 160 based on the identified current position of the mobile terminal 100. Search [S130].

In addition, the controller 180 may recognize the shape of one or more objects existing in the preview image 300, and search for object information corresponding to the recognized shape in the object information database in the memory 160. .

In addition, the object information includes a name of the object, a contact, a detailed location, and the like.

As described above, when object information regarding objects existing in the preview image 300 is searched for in the object information database, the controller 180 converts the searched object information to the positions of the corresponding objects in the preview image 300. Displayed in the augmented reality technique in [S140].

Next, the controller 180 detects whether a command for moving the specific first object 310a among the objects in the preview image 300 is input [S150]. The first object 310a may be an actual object in the preview image 300. For example, the first object 310a indicates that the first object 310a is a “desk”.
