Referring to FIGS. 1 to 3, the main algorithm of the digital signal processor 507 of FIG. 2 will be described.

When operating power is applied to the digital camera 1, the digital signal processor 507 executes initialization (step S1). When this initialization step S1 is executed, the digital signal processor 507 performs a preview mode (step S2). In this preview mode, the input image is displayed on the display panel 35.

Next, when the SH1 signal from the shutter release button 13 is turned on (step S3) as the user presses the shutter release button 13 only one step, the digital signal processor 507 performs a shooting mode. (Step S4).

Next, when signals corresponding to the setting mode are input among the input signals from the user input unit INP (step S5), the setting mode for setting the operating conditions according to the input signals from the user input unit INP is performed. (Step S6).

Also, if no end signal is generated, the digital signal processor 507 continues the following steps (step S7).

First, when a signal is generated from the playback mode button 42 in the user input unit INP (step S8), the playback mode is performed (step S9). This playback mode includes a file-classification mode. In this file-classification mode, thumbnail images are displayed, and when selection of thumbnail images desired by the user is completed, names of a plurality of folders are displayed. When a folder desired by the user is selected, files of the selected thumbnail images are moved to the selected folder. Therefore, convenience can be provided to the user as files stored in the recording medium can be sorted without the user using the computer. An algorithm for performing the playback mode (step S9) will be described in detail with reference to Figs.

When the reproduction mode ends, the steps are repeated.

FIG. 4 is a flowchart showing an algorithm of performing a play mode S9 of FIG. 3. 1, 2, and 4, the algorithm of performing the playback mode (S9) of Figure 3 will be described as follows.

First, the digital signal processor 507 controls the LCD driver 514 to display an image of a file recently stored in the memory card on the color LCD panel 35 as a reference standard (step S402). Here, the reference standard means a standard of one image displayed on all the display areas of the color LCD panel 35.

Next, the user presses the self-timer / right button 15 _R , the flash / left button 15 _L , the macro / down button 15 _D , and / or the voice-memo / up button 15 _U. When the direction signal is generated (step S404), the digital signal processor 507 controls the LCD driver 514 to display the image of the file corresponding to the generated direction signal on the color LCD panel 35 as a reference standard. (Step S406).

Next, when the tele-zoom button signal is generated by the user pressing the tele-zoom button 39 _T (step S408), the digital signal processor 507 controls the LCD driver 514 to display the currently displayed file. The magnified image is displayed on the color LCD panel 35 (step S410).

With the image magnified in this way, the user can set the self-timer / right button 15 _R , the flash / left button 15 _L , the macro / down button 15 _D , and / or the voice-memo / up button ( When the direction signal is generated by pressing 15 _U ) (step S412), the digital signal processor 507 controls the LCD driver 514 to move the display area of the enlarged image according to the generated direction signal (step S412). S414).

When the user generates a signal of the wide-zoom button 39 _W in this state in which the image is enlarged (step S416), the digital signal processor 507 controls the LCD driver 514 to display the currently displayed file. Image is displayed on the color LCD panel 35 according to the reference standard (step S418).

When the user generates a signal of the wide-zoom button 39 _W in the state where the image is displayed in the reference standard (step S421), the digital signal processor 507 performs an index-playback mode (step S425). ). In this index-playback mode, a plurality of thumbnail images may be displayed on one screen, and an image selected by the user may be displayed or enlarged and displayed as a reference standard.

Next, when the user operates the function buttons 15 to generate a file management signal (step S426), the digital signal processor 507 performs a file-management mode (step S427). Performing this file-management mode (step S427) will be described in more detail with reference to Figs.

Steps S404 to S427 are repeatedly performed until the playback mode button 42 is pressed by the user (step S428).

Referring to Figures 2 and 5, the main algorithm of performing the file-management mode (S427) of Figure 4 will be described as follows.

First, the digital signal processor 507 displays the file-management menu (step S427).

In this state in which the file-management menu is displayed, if the user selects the file-delete mode, the digital signal processor 507 performs the file-delete mode (steps S52 and S53).

Also, if the user selects the file-classification mode, the digital signal processor 507 performs the file-classification mode (steps S54 and S55).

Then, if the user selects the file-protection mode, the digital signal processor 507 performs the file-protection mode (steps S52 and S53). Files with file protection are not deleted immediately.

In the file-sort mode (step S55), thumbnail images are displayed, and when selection of thumbnail images desired by the user is completed, names of a plurality of folders are displayed. When a folder desired by the user is selected, files of the selected thumbnail images are moved to the selected folder. Therefore, convenience can be provided to the user as files stored in the recording medium can be sorted without the user using the computer. The file-sort mode (step S55) is described in detail below.

FIG. 6 shows a detailed algorithm of performing file-classification mode S55 of FIG. 5. FIG. 7 shows an example of an index screen displayed by performing step S601 of FIG. 6. FIG. 8 shows a state where an existing folder is selected in step S619 of FIG. 6. FIG. 9 shows an example of a folder-type menu displayed by performing step S621 of FIG. 6. FIG. 10 shows a state where a new folder is selected in step S623 of FIG. FIG. 11 shows an example of a folder-type menu displayed by performing step S625 of FIG. 6.

Reference numeral 35 in FIGS. 7 to 11 designates the color LCD panel of FIGS. 1 and 2. A detailed algorithm of performing the file-classification mode (S55) of FIG. 5 will be described with reference to FIGS. 1, 2, and 6 to 11.

First, the digital signal processor 507 displays an index screen including the thumbnail images TI1 to TI6 on the color LCD panel 35 (step S601, see FIG. 7). Any one of the thumbnail images TI1 to TI6 TI2 is activated by the activation cursor AC. In the present embodiment, six thumbnail images TI1 to TI6 are displayed on a single index screen.

Next, when the direction button signal is input by the user's operation (step S603), the digital signal processor 507 moves the activation cursor AC in accordance with the direction of the input direction signal (step S605).

Next, the digital signal processor 507 determines whether the selection confirmation signal for the currently activated file has been input by the user's operation (step S607). If the selection confirmation signal is input, the digital signal processor 507 determines whether the corresponding node number exists in the selection list (step S609).

Here, the node number refers to a serial file number in accordance with the generation order of the files stored in the memory card. For example, the first file created has a node number of '1'. In addition, the selection list means a list in which node numbers of files selected by the user for file management are recorded.

If the node number does not exist in the selection list, since the selection confirmation signal from the user wants to register the node number, the digital signal processor 507 registers the node number in the selection list (step S611).

On the contrary, if the corresponding node number exists in the selection list, since the selection confirmation signal from the user wants to delete the corresponding node number, the digital signal processor 507 deletes the corresponding node number from the selection list (step S613). .

Next, if the user inputs a selection completion signal (step S615), the digital signal processor 507 displays a folder-type menu (step S617).

Here, when the user selects an existing folder type (step S619, see Fig. 8), the digital signal processor 507 displays the names 100SSCAM, 101SSCAM of the existing folders (step S621, see Fig. 9). Also, when the user selects a new folder type (step S623, see Fig. 10), the digital signal processor 507 generates and displays the names 102SSCAM to 105SSCAM of the new folders (see steps S625 and Fig. 11).

Next, when the user's folder selection is completed (step S627), the digital signal processor 507 moves files of the node numbers registered in the selection list to the selected folder (step S629).

12 shows an example of the structure of files stored in the recording medium before the file-classification mode of FIG. 5 is performed. FIG. 13 shows an example of the structure of files stored in the recording medium after the file-classifying mode of FIG. 5 is performed.
