As shown in FIG. 1, a wireless communication terminal to which the present invention is applied includes a digital signal transmitted through a wireless transceiver 11 and a wireless transceiver 11 for wirelessly transmitting / receiving a signal through an antenna. To convert the voice signal and / or sound signal, and convert the voice signal and / or sound signal received from the voice / sound input unit (microphone) 14 into a digital signal to be transmitted through the wireless transceiver 11. A codec 12, a voice / sound output unit 13 for outputting a voice signal and / or a sound signal received from the codec 12, and receives a voice signal or / and a sound signal. Audio / sound input unit 14, receiver telephone number, caller telephone number, video data, text data, short message, multimedia message, schedule information, location information, search box, and camera unit for transmission to codec 12 19 The display unit (LCD) 15 for displaying the obtained image and the like under the control of the control unit 20, various function keys and numeric keys are provided for information (telephone number, personal information) necessary for the wireless communication terminal, Storing a key input unit (keypad) 16, a phone number, a schedule, a database (search information), an image file, a video file, etc. for receiving a search word, an image file search signal, a mode setting signal, a storage signal, a shooting signal, and the like. Storage unit 17, a GPS receiver 18 for receiving location information (shooting location) from a GPS (Global Posioning System), a camera unit 19 for capturing an image of a subject, and the camera unit according to a storage signal An image file is generated using the image data acquired through (19), the search information (shooting location, index) of the generated image file is obtained and databased, and the image file search mode is set. The database search for the file, and a controller 20 for controlling the respective components so as to display the searched file.

2 is a flowchart illustrating a method of storing an image file in a wireless communication terminal according to the present invention.

First, a search information storage mode for databaseing search information of an image file when the image file is stored is set. Of course, if the retrieval information storage mode is not set, the retrieval information of the image file is not databased. Here, the search information storage mode is a term arbitrarily named and can be changed to another appropriate term.

Subsequently, image data is generated as the image of the subject is captured by the camera unit 19 (operation 201).

Thereafter, it is checked whether the generated image data is stored (202). That is, after displaying a message asking whether to save the generated image data or not, the user determines whether the input signal from the user is a stored signal or a non-save signal. In this case, the image data is stored in the form of an image file, and the type of the image file is a JPEG (Joint Photographic Expert Group) file.

If the result of the check 202, the input signal from the user is a non-storage signal, it ends, if the stored signal generates a video file using the video data (203), the generated video file to the storage unit 17 Save (204). At this time, the controller 20 checks the storage address (index) of the storage 17 in which the image file is stored.

Then, the GPS receiver 18 acquires the location information of the current wireless communication terminal from the GPS satellite (205). In this case, the display unit 16 additionally displays the acquired location information so that the user can recognize what the search term is when the user searches for the current photograph.

Thereafter, the index information and the location information are databaseized and stored in the storage unit 17 (206). At this time, if there is more image to be photographed, the process proceeds to step “201”, and the subsequent process is performed.

Here, the process of databaseting the index information and the location information will be described in more detail.

First, when taking an image, image data is generated, and when the image data is stored in the storage unit 17 in the form of a file, the database is stored using the index, which is the position where the image file is stored in the storage unit 17, and the position information acquired from the GPS satellites. Make up. Therefore, when a user later searches for an image file photographed at a specific location through the search information database, the user may search for the actual image file stored in the storage unit 17 through an index corresponding to the location information.

For example, to explain these processes more easily, suppose that you go to Gyeongpodae Beach and take pictures (pictures) using friends and a wireless communication terminal equipped with a camera.

First, a search information storage mode is set through a menu of a wireless communication terminal, and then an image is taken. When the storage signal is input, the wireless communication terminal stores the image data in the form of an image file. At this time, the index information stored in the image file and the location information (Gyeongpodae Beach) obtained through the GPS receiver 18 is made into a database and stored in the storage unit 17.

In addition, suppose that you go to an amusement park and take pictures (pictures) using a wireless communication terminal equipped with a camera with friends. First, a search information storage mode is set through a menu of a wireless communication terminal, and then an image is taken. When the storage signal is input, the wireless communication terminal stores the image data in the form of an image file. At this time, the index information stored in the image file and the location information (for example, Lotte World) obtained through the GPS receiver 18 are databased and stored in the storage unit 17.

In this way, if you search for pictures taken at Gyeongpodae Beach among many pictures taken at various locations (places), you can enter "Gyeongpodae Beach" in the search box and the wireless communication terminal searches for the corresponding video files through the search information database. To display.

In the present invention, the location information may be obtained through the GPS receiver 18 or may be arbitrarily set by the user.

3 is a flowchart illustrating an image file search method in a wireless communication terminal according to the present invention.

First, the storage unit 17 stores image files obtained through the process of FIG. 2.

Thereafter, the user sets the wireless communication terminal to an image file search mode in order to search for an image file photographed at a specific place (301). At this time, the wireless communication terminal displays a search window through the display unit 15.

Thereafter, as a corresponding search word (location information) is input from the user through the key input unit 16, the search information database is searched (302 and 303). At this time, the retrieval information database stores location information and index information for each video file.

Thereafter, the retrieved image files are displayed (304). At this time, when a video file search signal is simply input without receiving a specific search word, the video files in the database are listed and displayed by location information (region). That is, for example, 1) Yeouido, 2) Gyeongpodae, 3) Jamsil or the like, or a.jpg (Yeouido), b.jpg (Gyeongpodae), c.jpg (Jamsil) and the like.

Through this process, a user can quickly search for an image file photographed at a specific place without inputting additional information when storing the image file.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

In the present invention as described above, by storing the image file generated according to the storage signal of the image data, by obtaining the search information (shooting location, index) of the image file to make a database, the desired image file can be quickly It has the effect of making it searchable.

In addition, the present invention has an effect that can be quickly retrieved image file taken in a specific place even if the image file is stored without storing additional information input.
