A method of linking a function of a terminal includes recognizing a face included in a photo, determining whether there is phonebook information having a photo of a face matched with the recognized face, and generating a gallery-phonebook file. The matched phonebook information is linked with the recognized face. The phonebook information of the gallery-phonebook file is based on the phonebook file stored in the storage unit and a controller determines whether or not to update the phonebook file if a recording date of the phonebook information included in the gallery-phonebook file is older than generation date of the phonebook file stored in the storage unit.
