9. A method of controlling a mobile terminal, the method comprising: allowing, via a wireless communication unit, wirelessly communication with at least one other terminal; receiving user-inputs via a user input unit; capturing, via a camera, a camera preview image; displaying, on a touchscreen, the camera preview image; obtaining, via a position-location processor, information on a current position of the mobile terminal; photographing, via a controller, the camera preview image; assigning a first identifier to the photographed camera preview image indicating a photographing time when the photographed camera preview image was captured; storing, via the controller, the photographed camera preview image as a picture file; searching, via the controller, the textual object information by using the assigned first identifier and a position and direction of the mobile terminal when the camera preview image was captured; obtaining, via the controller, a second identifier and textual object information corresponding to the second identifier; matching, via the controller, the second identifier with the first identifier assigned to the photographed preview image; outputting, via the controller, query information to a user to query whether the searched textual object information is to be stored separate from the picture file, or within a synthesized picture file that includes the camera preview image and the searched textual object information; storing, via the controller, the picture file and the searched textual object information when the answer to the output query information is to not synthesize the camera preview image with the searched textual object information; storing, via the controller, only the synthesized picture file and not the searched textual object information when the answer to the output query information is to synthesize the camera preview image with the searched textual object information; changing, via the controller, the searching distance from the current position when the user input unit receives a specific user-input from the user; displaying the searched textual object information with the picture file when the answer to the output query information is to not synthesize the camera preview image with the searched textual object information; and displaying only the synthesized picture file when the answer to the output query information is to synthesize the camera preview image with the searched textual object information, wherein a first portion of the textual object information including non-variable information regarding the object within the camera preview image is obtained from the object information database, and a second portion of the textual object information including variable information regarding the object is obtained from an external server.

The method of claim 9 , wherein if the answer to the output query information indicates the picture file is to be stored together with the textual object information, the method further comprises outputting synthesized information querying whether or not the textual object information is to be synthesized with the picture file, and wherein if an answer to the output synthesized information indicates the textual object information is not to be synthesized with the picture file, the method further comprises storing the textual object information and the picture file as separate files, and storing linking information linking the picture file and the textual object information.
