In the tenth step S10 of FIG. 4, when the additional information setting button 13c of the input and display unit 13 is operated by the user, the setting unit 14 is input as a setting command as shown in FIG. 2. The metadata application rule is set to selectively use location information and additional information in the file name and metadata of the image file.

In the twelfth step S12, the photographing unit 12 photographs a UCC such as a picture or a video. In the fourteenth step S14, the location information receiving unit 11 receives a GPS signal including location information from the GPS satellites. To calculate the current position. In operation 16, the controller 15 may store the weather information 64 shown in FIG. 3 in the storage 16, the name 68 of the creator who created the image file, the age, the telephone number, Additional information including personal information consisting of the device name 69, schedule information consisting of the event 65 or schedule, appointment and group information 66, date / time information 67, and biorhythm information is searched for. In this case, the communication module 19 may download the additional information in real time from an external computer system, the server 30, or the base station 40.

Subsequently, in step 18, the controller 15 generates a file name and metadata using only the corresponding data among the received location information and the searched additional information according to the metadata application rule set in the tenth step S10. do.

In the twentieth step S20, the input and display unit 13 displays the photographed image information, the generated file name, and additional information on the screen, and waits until a storage command is input from the user.

When the storage command is input, in step 22, the controller 15 adds the metadata to a header or tail to generate an image file. In this case, the controller 15 preferably adds the watermark to the generated image file so that the original author can be identified.

In step 24 (S24), the controller 15 controls to store the image file and metadata in the storage unit 16 in the form of a library database. Accordingly, the controller may provide a search function using a search word by using the index of the image file and the metadata.

In detail, in operation 26, the input and display unit 13 receives a search word for searching the image file. Then, in operation 28 (S28), the search unit 17 searches for the index of the file name and metadata of the image file based on the search word in the storage unit 16 storing the image file. To provide. Accordingly, the search unit 17 provides a search function of a library method based on a search word by using various indexes added as a file name and metadata of an image file, unlike a search environment for searching for a file by searching for a corresponding folder.

In operation 30, the input and display unit 13 displays the searched image file list on the screen. In this case, the input and display unit 13 may display the image file list in various forms such as text form or thumb nail form.

Through the above process, the present invention adds location information and additional information to an image file, and stores the image file and its standardized metadata in the form of a library database. Accordingly, the present invention provides a library type search function using a search word.

Next, a method of uploading an image file and metadata from a portable terminal to a computer system according to an exemplary embodiment of the present invention will be described in detail with reference to FIG. 5.

In step 40 of FIG. 5, the communication module 19 is connected to the computer system or the server 30 through the USB.

Then, in step 42 (S42), the control unit 15 controls to transmit the metadata format of the image file stored in the storage unit 16 through the communication module 19.

When the connected computer system or server 30 supports the metadata format, in step 44, the communication module 19 selects image files to be transmitted through the input and display unit 13. Receive and send. At this time, the computer system or the server 30, such as the portable terminal 10, so as to provide a library-type search function, the folder structure and folder name of the same type as the storage unit 16 of the portable terminal 10, It is preferable to save the image files in a file name.

Accordingly, the computer system or the server 30 may receive a search word using the metadata and search for and provide the image file in steps 46 through 50.

Next, the method of guiding the way of the mobile terminal according to an exemplary embodiment of the present invention will be described in detail with reference to FIG. 6.

In steps 60 through 66 of S66 of FIG. 6, the input and display unit 13 displays a list of image files searched according to a search word from the search unit 17 on the screen, and the image files selected from the displayed lists. Play it.

During the playback of the video file, if the position setting button 13b for setting the video file to be played back on the screen of the input and display unit 13 as a destination is operated in step 68 (S68), in step 70 (S70). The controller 15 checks the location information of the image file and sets the location as a destination. Subsequently, in step 72, the controller 15 performs the road guidance to the set destination using the map information stored in the storage 16. Of course, the controller 15 may set the location information of the image file as a source or the POI according to the operation of the location setting button 13b.

Through the above process, the present invention adds a file name and standardized metadata using location information and additional information to an image file and makes a database. Accordingly, the present invention provides a search function of an image file using a search word and performs a road guide using the location information of a reproduced image file.
