The current location information signal is then transmitted through the second wireless communication unit 21. Since the second mobile terminal 20 and the first mobile terminal 10 are within the predetermined range, the location information acquired by the GPS unit 22 can be regarded as the location information of the first mobile terminal 10, that is, the location information of the shooting location.

The processing unit 14 receives the location information signal of the shooting location through the first wireless communication unit 11, and obtains the location information of the shooting location from the location information signal of the shooting location, and the location information of the shooting location is standard. The Exif (Exchangeable Image File) format is written to the JPEG image taken by the camera unit 12.

The processing unit 14 is further configured to store the image of the write location information in the storage unit 13.

In this embodiment, the processing unit 14 is further configured to read the longitude/latitude position information of the shooting location from the image when the image of the writing location information is decoded for browsing, thereby facilitating the user. In the future, the location where the image was originally taken is checked through an electronic map.

Please refer to FIG. 2 , which is a flowchart of a target positioning method according to an embodiment of the present invention.

In step S201, the processing unit 14 controls the camera unit 12 to take an image of the target in response to the user's operation.

In step S202, the processing unit 14 simultaneously transmits a location demand signal through the first wireless communication unit 11 within a predetermined range.

In step S203, the control unit 23 receives the location demand signal through the second wireless communication unit 21.

In step S204, the control unit 23 controls the GPS unit 22 to acquire current location information. Since the second mobile terminal 20 and the first mobile terminal 10 are within the predetermined range, the location information acquired by the GPS unit 22 can be regarded as the location information of the first mobile terminal 10, that is, the location information of the shooting location.

In step S205, the control unit 23 transmits a signal of the location information of the shooting location through the second wireless communication unit 21.

In step S206, the processing unit 14 receives a signal of the location information of the shooting location through the first wireless communication unit 11.

In step S207, the processing unit 14 acquires the location information of the shooting location from the location information signal of the shooting location, and writes the location information of the shooting location into the image in a standard Exif format.

In step S208, the processing unit 14 stores the image in which the location information is written into the storage unit 13.

In step S209, when the processing unit 14 decodes the picture for browsing, the location information of the shooting location is read from the image in which the location information is written for the user to view on the electronic map.

It is to be understood by those skilled in the art that the above embodiments are only intended to illustrate the invention, and are not intended to limit the invention, as long as it is within the spirit of the invention Changes and modifications are intended to fall within the scope of the invention.
