Accordingly, the controller 180 may obtain object related information of each of at least one object located within a predetermined distance from the mobile terminal 100.

The obtaining of the object related information (S320) will be described in more detail below.

First, the mobile terminal 100 pre-stores object related information for each object in the memory 160 and stores the object related information for each object in the input image from the object related information for each object previously stored in the memory 160 under the control of the controller 180. You can search for relevant object information. In this case, the memory 160 may store location information of the object having the object related information together with the object related information.

More specifically, the controller 180 may search the memory 160 for a plurality of objects having location information within a predetermined distance from the mobile terminal 100 and object related information designated for each of the plurality of objects. Accordingly, the controller 180 may obtain object related information of each of the plurality of objects within a predetermined distance from the mobile terminal 100 by searching for object related information for each object stored in the memory 160.

Furthermore, object-related information and location information for each object previously stored in the memory 160 may be received from an external server or stored by default at the time of terminal production. In addition, object-related information and location information for each object previously stored in the memory 160 may be updated periodically or at any time.

Next, the mobile terminal 100 may receive object related information corresponding to the input image from an external server through the wireless communication unit 110.

More specifically, the mobile terminal 100 transmits a signal for requesting object related information of each of a plurality of objects located within a predetermined distance from the mobile terminal 100 to an external server, thereby forwarding the front schedule from the mobile terminal 100. Object-related information of each of a plurality of objects located within a distance may be received.

In this case, the request signal may include location information of each of the plurality of objects (electronic), or may include a predetermined distance for displaying location information and object related information of the mobile terminal 100 (the latter).

In the former case, the mobile terminal 100 may receive object related information corresponding to the location information included in the request signal from an external server. In the latter case, the mobile terminal 100 may receive object related information of each of a plurality of objects located within a predetermined distance from the current position of the mobile terminal 100 from an external server.

The mobile terminal 100 displays the image input in the input step S310 under the control of the controller 180, and displays the object related information obtained in the obtaining step S320 within the input image ( S440). The display step S440 may be performed using the display unit 151.

The object related information may be displayed in association with an object image corresponding to the corresponding object in the input image. For example, when the object related information is "LG electronic" and the corresponding object is an LG electronic building, the object related information "LG electronic" may be displayed in association with the image of the LG electronic building in the input image.

Furthermore, even when there is no object image corresponding to the object related information in the input image, the object related information may be displayed at a position where the corresponding object image is expected to exist in the input image.

The mobile terminal 100 receives a zoom-in command signal for the camera 121 through the user input unit 130 (S340). When the mobile terminal 100 receives the zoom-in command signal, the mobile terminal 100 zooms in the image input through the camera 121 under the control of the controller 180 (S350).

Here, the zoom-in command signal may include a signal for effecting receiving the image at a position closer to the subject than the actual position by adjusting the focal length while fixing the position of the camera 121.

For example, when the zoom-in command signal is input, the image may be input by advancing a predetermined distance from the current position with respect to the same subject even though the position of the camera 121 is fixed. Therefore, the image input through the camera 121 may be displayed to be enlarged closer and closer than before the zoom-in command signal is input. Alternatively, when the zoom-in command signal is input, since the image is input by moving a predetermined distance from the current position, the subject existing between the current position and the advanced position (virtual) may not be displayed.

In the input step S340, a menu item corresponding to the generation of the zoom-in command signal, a key (or a key area) is selected by the user, or a terminal movement (eg, tilting forward / backward, constant, or corresponding to the zoom-in command signal) is performed. The number of times of shaking, etc.) or a touch action corresponding to the zoom-in command signal is input by the user.

The input step S340 may receive a zoom-in command signal for the input image while displaying the obtained object related information in the image input through the camera 121.

The mobile terminal 100 controls the display of object related information displayed in the input image to correspond to the zoom-in degree of the image under the control of the controller 180 (S360).

In operation S360, the mobile terminal 100 may differently set object related information displayed on the same object to correspond to the zoom-in degree of the image under the control of the controller 180.
