Hereinafter, a process of controlling a camera photographing function according to storing a photographic file taken when photographing in a mobile communication terminal according to an embodiment of the present invention will be described with reference to FIG. 2. 2 is a control flowchart of a process of storing a photo file taken in a photo folder according to an exemplary embodiment of the present invention. Also, FIG. 3 is a diagram illustrating a screen for selecting a photo folder from a user when storing a photo file according to an embodiment of the present invention.

First, the control unit 100 proceeds to step 205 according to the user's selection of the picture taking mode in step 200 and determines whether the picture taking is completed. At the same time as the photographing is completed according to the determination result, the controller 100 displays a message on the display 110 asking whether to save the photographed photo file. Then, when the storage of the photo file is selected by the user in step 215, the control unit 100 proceeds to step 220, and typically receives a picture title from the user in order to facilitate the classification of the picture file. When the photo title input is completed, the control unit 100 proceeds to step 225 and displays a message asking whether the user selects and saves a specific photo folder desired by the user when storing the photo file.

If the control unit 100 selects not to designate a specific picture folder for storing the photographed picture file in response to a message asking whether to select and save a specific picture folder in step 230, it proceeds to step 235. Proceed and save the photo files taken in the default photo folder. In contrast, when a selection is made to designate a specific photo folder for storing a photo file taken by a user, the controller 100 proceeds to step 240 and displays the photo folder item as shown in FIG. 3. Display via. Here, as shown in FIG. 3, the screen displaying the item of the picture folder displays a picture folder index previously created by the user and a picture folder name mapped to the index. These picture folder items include a default folder in addition to the picture folder created by the user.

As described above, when the picture folder item is displayed as shown in FIG. 3, the picture folder item moves to the corresponding picture folder in response to a direction key input by the user. Then, in step (245), if there is a selection to designate a picture folder generated by the user to store the picture file taken by the user in addition to the default folder, the control unit 100 proceeds to step (250) to capture the selected picture folder. Save the picture file. On the other hand, when the user does not select the photo folder created by the user in step 245, the controller 100 stores the photo file photographed in the default folder in step 235.

The photographed picture file is stored in the memory unit 130 in the format as shown in FIG. 4 together with the picture title input by the user. 4 is a diagram illustrating a picture file storage format according to an embodiment of the present invention. Referring to FIG. 4, each photo file is stored in a photo file format as shown in FIG. 4 including photo file related information, that is, data about the photo file. Data for such a picture file includes a picture title entered by the user, a folder index for the picture folder designated by the user, a picture creation date, picture size, picture decoding data, and the like. Here, the folder index according to an embodiment of the present invention specifies a picture folder name where a picture file is stored. In an embodiment of the present invention, the picture folder name where a picture is stored is not stored in the memory unit 130, but the corresponding picture. By storing a folder index for specifying a folder, it is possible to designate a corresponding picture folder with only a small storage space in the memory unit 130.

In other words, according to an embodiment of the present invention, a field for a photo folder that can create or delete an arbitrary photo folder by a user is added to data for a photo file, and the added field is referred to as a folder index. If the field for such a folder index is set to a size of 1 byte, up to 255 photo folders may be created in the mobile communication terminal. According to an embodiment of the present invention, the memory unit 130 is allocated a space for mapping the folder index to store the photo folder name input by the user.

For example, as shown in FIG. 5, a corresponding picture folder name is stored by mapping to a folder index, and the folder index indicates an index of a table managing the picture folder name. 5 is a diagram illustrating a folder name mapped to a folder index according to FIG. 4. If the picture folder name mapped to the folder index is NULL, this means that the folder index is unspecified by the user and that the picture folder name is not input by the user. However, even when a picture folder name is not input by a user, a specific picture folder such as a basic folder or a trashcan folder may be mapped to any folder index. In other words, according to an embodiment of the present invention, the picture folder includes a specific folder such as a default picture folder and a trash folder for storing unused or deleted picture files in addition to the picture folder created by the user.

As described above, the memory unit 130 is allocated a space for storing up to 256 photo folder names. The photo folder name includes a NULL value as an initial value, and the photo folder name is input by the user. In addition, each time a picture folder name input by a user is stored in an empty space among 256 allocated spaces, each time it is created. When displaying the picture file list stored in the corresponding picture folder when searching for the picture file taken afterwards, the controller 100 analyzes the folder index value in each picture file type and searches the same folder according to the analyzed folder index value. Group photo files with index values. Accordingly, when only the picture files having the same folder index value are read, the controller 100 may display the picture files in the same picture folder by grouping the picture files by the picture folder name mapped to the folder index.

For example, the folder index of the picture file having the picture title of "Hong Gil-dong" and "Friends" shown in FIG. 4 is equal to "2". The picture files having the same folder index are stored together in the picture folder of the picture folder name mapped to the folder index. In other words, as shown in FIG. 5, when the folder index is "2", the photo file having the photo titles of "Hong Gil-dong" and "Friends" is stored in the photo folder having the photo folder name "Friends".

Next, a photo folder editing process for creating or deleting a photo folder in order to classify and store photographed photo files according to an exemplary embodiment of the present invention will be described with reference to FIG. 6. In addition, to clearly illustrate this, reference is made to FIG. 7, which is an exemplary view showing an item of editing a photo folder of FIG. 6.

First, in response to a request for editing a photo folder from the user in step 600, the controller 100 displays a photo folder editing menu as shown in FIG. 7 in step 610. When the picture folder editing menu is displayed, the picture folder list is displayed when storing the taken picture file, there is a key input corresponding to the picture folder editing request from the user, or a menu selection for picture folder editing from the user in the picture recording mode. If it is.

As such, after the controller 100 displays the photo folder menu, the controller 100 proceeds to step 620 to determine which one is selected from the user. That is, the controller 100 determines whether the user selects one of "1. Add new folder" and "2. Modify folder name" as shown in FIG. 7. If the selected menu is “1. Add new folder”, the controller 100 proceeds to step 660, and if the selected menu is “2. Modify folder name”, proceeds to step 630. FIG.

If the first selected folder is “2. Modify folder name”, the control unit 100 displays a photo folder list including the folder name as shown in FIG. After receiving the selection, you will be prompted to enter a new name for the selected picture folder. Then, the control unit 100 proceeds to step 650 to store the photo folder name with the new name input by the user in the allocated memory area of the memory unit 130 to store the photo folder name.

On the other hand, if the selected folder is "1. Add a new folder", the control unit 100 proceeds to step 660 to receive a new folder name from the user, and proceeds to step 670 to create a new folder with the input folder name. . As described above, the user may create or modify a photo folder through the photo folder edit menu.

Subsequently, after storing the captured photo file, a process for copying, moving, and deleting the photo file according to an embodiment of the present invention will be described with reference to FIG. 8. 8 is a flowchart illustrating a process of copying, moving, and deleting a photo file according to an exemplary embodiment of the present invention.

Then, the controller 100 displays a list of a plurality of photo files stored in the photo folder as shown in FIG. 9 (a). When the desired photo file is selected by the user from the list of displayed photo files, the control unit 100 proceeds to step 810 to edit, copy, move, and delete the photo file as shown in FIG. 9 (b). Display the menu.

Here, as shown in FIG. 9 (b), when an item such as “1. Copy”, “2. Move”, “3. Delete”, which is an edit menu for copying, moving, or deleting a photo file is displayed, the controller ( 100 determines whether one of the photo file editing menus is selected by the user.

First, to describe the case where "1. Copy" is selected in the Edit menu selection of the submenu of the photo file list as shown in FIG. 9 (a), select the desired photo file and select "1. If it is selected, the controller 100 proceeds to step 820 and displays a screen for selecting a photo folder to paste the selected photo file as shown in FIG. 3. If the picture folder to be pasted by the user is selected on the screen, the control unit 100 proceeds to step 830 and the copying is completed. In executing the copy, the user can select one or more photo files to copy. For example, as shown in FIG. 9 (a), when a list of picture files in a corresponding picture folder is displayed, a user presses a specific key button provided on one side on a mobile communication terminal and then selects a number of picture files contained in the picture folder. Choose the designation.

Next, to describe the case where "2. Move" is selected in the Edit menu selection of the sub-menu of the picture file list as shown in FIG. 9 (a), the above-described case of "1. Copy" is selected. In the same manner, when the desired photo file is selected, the controller 100 displays the photo folder list as shown in FIG. 3 in order to receive the selection of the photo folder to be moved from the user in step 840. If the user selects a folder of pictures to be moved by the user, the control unit 100 proceeds to step 850 and the movement is completed. In the case of selecting " 2. Move " here, unlike the case of selecting " 1. Copy " described above, it means to completely move information from the picture folder to which the picture file belongs to the picture folder to be moved.

Lastly, in the case where “3. Delete” is selected in the edit menu selection of the submenu of the photo file list as shown in FIG. 9 (a), the control unit 100 proceeds to step 860. If "3. Delete" is selected by the user, if the corresponding picture file is deleted from the user, the deletion is completed. On the other hand, such a deletion function has a deletion function for deleting the corresponding picture files one by one and a deletion function for deleting the entire picture files belonging to the recycle bin folder at one time by using the recycle bin folder. In addition, in another embodiment of the present invention, if the Delete menu is selected from the Edit menu for editing a photo file, the selected photo file may be moved to the Trash folder, and when the user is instructed to empty the Trash folder, all the photo files in the Trash folder Can be deleted.
