In other words, when a user inputs a name such as a local name and a building name that he / she wants to see through the user input unit 130, the controller 180 receives location information of the input name.

The controller 180 changes the position information into geographic coordinate information (S103). The geographic coordinate information includes information such as latitude and longitude. For example, when the user inputs "Seoul Station" as the location information, the controller 180 converts the map data into geographic coordinate information such as latitude and longitude corresponding to the "Seoul Station".

The controller 180 searches for at least one terminal registered in the base station in the region corresponding to the geographical coordinate information (S104). In other words, the controller 180 searches for a terminal registered with the base station serving a region corresponding to the geographical coordinate information. In this case, the controller 180 may search for a predetermined number of terminals in the order of proximity to the geographical coordinate information among the terminals located in the service area of the base station.

When the search of the terminal is completed, the controller 180 transmits a message requesting a scene image together with the geographical coordinate information to the searched terminals (S105). The controller 180 may attach and transmit an advertisement of a corresponding region to the request message.

The terminal receiving the request message photographs a scene image and transmits the scene image to the requesting terminal.

The controller 180 of the mobile terminal 100 receives the transmitted field image through the wireless communication unit 110 (S106). In other words, the controller 180 receives the field image provided by the terminal that received the request message.

The controller 180 displays the received field image on a display screen (S107).

FIG. 6 is a diagram illustrating a screen in which a mobile terminal according to the exemplary embodiment of FIG. 5 shares a field image.

First, the controller 180 executes a scene image viewing application according to a user input. The controller 180 displays the execution screen on the display screen (a). The execution screen displays icons for selecting a location information input method. As the location information input method, the following method may be used. First, input names such as place names and building names. The second is to enter the address of the desired place (region). The third method is to select any one of recent inputs, and the fourth method is to select any one of favorite location information.

If any one of the icons on the execution screen is selected, the controller 180 displays an input screen for inputting location information (b). The input screen includes a text input window into which location information input by a user is inserted and a virtual keypad for inputting the location information. For example, when the building name "Rome Pantheon" is input by the user's virtual keypad manipulation, the controller 180 inserts the building name entered in the text input window.

When the input of the location information is completed, the controller 180 converts the geographic coordinate information corresponding to the input location information, and searches the terminal registered in the base station in the corresponding area by the converted geographic coordinate information. The controller 180 lists the searched terminals starting from the nearest terminal based on the geographical coordinate information. In this case, the controller 180 may display a point where each terminal is located on a map. In addition, the controller 180 may select at least one or more of the terminals listed above and request a field image only to the selected terminal.

The terminal searches and the controller 180 generates a message including the input location information. In this case, the controller 180 changes the input location information into geographic coordinate information and attaches the generated message. When the message is generated, the controller 180 displays the generated message on the display screen (c). Here, the controller 180 may transmit the generated message directly to the searched terminal without outputting the generated message to the display unit 151.

When editing a message displayed on the display screen, the message input window may be touched to switch to the message edit mode to edit the message.

When the message editing is completed, the controller 180 transmits the generated message to the searched terminal according to a user's transmission command. That is, the controller 180 transmits a message requesting a field image to the searched terminal.

If the scene image is received from the searched terminal after transmitting the request message, the controller 180 displays the received scene image on a display screen (d). In this case, the controller 180 may display a list of the received scene images in a thumbnail form on the display screen. In addition, when any one of the received list of scene images is selected, the controller 180 displays the selected scene image on a display full screen.

7 is a flowchart illustrating a method in which a mobile terminal according to an embodiment of the present invention photographs a field image and transmits it to a requesting terminal.

The controller 180 of the mobile terminal 100 receives a field image request message through the wireless communication unit 11 (S201). For example, the terminal located in the area A transmits a message requesting a scene image of a specific place located in the area B. When the base station serving area B receives the request message, the base station transmits the received message to at least one terminal located in the service area of the base station.

Upon receiving the request message, the controller 180 drives the camera 121 (S202). In this case, the controller 180 of the terminal receiving the request message displays the received message on a display screen. When the user who confirms the request message executes the field image sharing function to provide the field image, the controller 180 drives the camera 121 and acquires the field image according to a user input.

The controller 180 obtains a scene image through the driven camera (S203).

The controller 180 transmits the obtained captured image to the requesting terminal (S204). In this case, the controller 180 may attach and transmit a predetermined advertisement to the obtained captured image. The predetermined advertisements are advertisements such as local advertisements and product advertisements, and are implemented as images and texts.

FIG. 8 illustrates an example in which a mobile terminal according to the embodiment of FIG. 7 provides a field image.

When the control unit 180 of the mobile terminal 100 receives a request message for requesting a scene image through the wireless communication unit 110, the controller 180 displays the received message on a display screen in a pop-up form (a).

When the sharing icon is selected by the user who checks the request message displayed on the display screen, the controller 180 drives the camera 121 (b).

After driving the camera 121, the controller 180 controls the camera 121 according to a user's input to capture a field image. The controller 180 displays the captured scene image on the display screen as a preview screen (c).

When a transmission command is input from a user who checks the captured scene image on the preview screen, the controller 180 transmits the captured scene image to the request terminal. The controller 180 returns to the photographing screen when the reshooting icon is selected by the user. In addition, when the cancel icon is selected, the controller 180 does not execute on-site image sharing.

According to an embodiment of the present invention, the above-described method may be embodied as computer readable codes on a medium in which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . In addition, the computer may include the controller 180 of the terminal.

The above-described terminal is not limited to the configuration and method of the above-described embodiments, the embodiments may be configured by selectively combining all or a part of the embodiments so that various modifications can be made have.
