The present invention relates to a control method of a digital image processing apparatus and a digital image processing apparatus using the method, and more particularly, to a digital image processing apparatus for reproducing and managing image files stored in a recording medium in a reproduction mode. A control method, and a digital image processing apparatus using the method, for example, a digital camera or a camera-phone.

Conventional digital image processing apparatus For example, the digital camera of the 2004 United States Patent No. 119,876 (name of the invention: Method of notification of inadequate picture quality), which is patented by the applicant is a recording medium, display unit, direction signal A generator, and a controller. Directional signal generator For example, the four-directional buttons generate four-directional signals according to a user's manipulation. Controller For example, a digital camera processor plays back and manages image files stored on a recording medium in a playback mode.

In the reproduction mode of the conventional digital image processing apparatus as described above, a user can manage files stored in a recording medium, for example, a memory card. For example, a user may select desired files and then delete, copy, lock, and print the selected files.

Here, in the process of selecting the files desired by the user or deselecting some of the selected files, the files are reproduced in the file storage order or vice versa according to the input direction signals. Accordingly, in order to cancel the selection of some of the selected files, it is inconvenient for the user to generate a large number of direction signals in order to find the file to be canceled.

For example, 1,000 image files are stored on a recording medium, and after the user selects the 20th, 150th, 300th, and 800th image files for file management, the 800th image file is stored. In order to deselect the 300th image file while the image is activated on the display panel, a process of playing 500 images is necessary. Therefore, when nine thumbnail images are displayed on a single index screen, the user may repeatedly search for the 300th image file after displaying 55 index screens by repeatedly operating one direction button.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and the digital image processing enables the user to quickly cancel the selection of some of the selected files after selecting the target files for managing the files in the playback mode.

In the step (b), when the first direction-signal is input, the activation cursor is moved to the adjacent thumbnail image of the currently active thumbnail image among all the thumbnail images. In the step (c), when the second direction-signals are input, the activation cursor is moved to one thumbnail image among the thumbnail images currently selected for management.

The digital image processing apparatus of the present invention for achieving the above object includes a recording medium, a display unit, a direction signal generator, and a controller. The direction signal generator generates direction signals according to a user's manipulation. The controller reproduces and manages the image files stored in the recording medium in the reproduction mode. Here, the control algorithm performed by the controller comprises steps (a) to (c). In the step (a), the controller displays an index screen of thumbnail images, which are reduced images of image files stored in the recording medium, and an activation cursor for selecting a thumbnail image on the display unit. . In the step (b), when the first direction-signals are input from the direction signal generator, the controller moves the activation cursor to the adjacent thumbnail image of the currently active thumbnail image among all the thumbnail images. In the step (c), when the second direction-signals are input from the direction signal generator, the controller moves the activation cursor to one thumbnail image among the thumbnail images currently selected for management.

According to the control method of the digital image processing apparatus of the present invention, and the digital image processing apparatus using the method, a thumbnail image of the currently selected thumbnail images by the user generating the second direction-signals The activation cursor is moved.

On the other hand, the microcontroller 512 drives the flash 12 by controlling the operation of the flash controller 511 according to a signal from a flash-light amount sensor (not shown).

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

When operating power is applied to the digital camera 1, the digital camera processor 507 executes initialization (step S1). When this initialization step S1 is executed, the digital camera processor 507 performs a preview mode (step S2). In this preview mode, the input image is displayed on the display panel 35. Operations associated with this preview mode will be described in detail with reference to FIG. 4.

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 camera processor 507 changes the current shooting mode. (Step S4). An algorithm for performing the shooting mode (step S4) will be described in detail with reference to FIG.

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 entered. Is performed (step S6).

In addition, if no end signal is generated, the digital camera 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). In the reproduction mode, the reproduction operation is performed in accordance with the input signals from the user input unit INP. 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.

1, 2, and 4, the algorithm of performing the preview mode (S2) of Figure 3 will be described as follows.

First, the digital camera processor 507 performs an automatic white balance (AWB) operation to set parameters related to the white balance (step S201).

Next, the digital camera processor 507 performs an automatic exposure operation (step S202). In this automatic exposure operation (step S202), the digital camera processor 507 calculates the incident luminance, drives the aperture driving motor M _A in accordance with the calculated incident luminance, and sets the exposure amount.

Next, the digital camera processor 507 performs an automatic focusing operation (step S203).

Next, the digital camera processor 507 performs gamma correction on the input image data (step S204), and performs scaling on the input image data on which the gamma correction has been performed to meet the display standard. (Step S205).

Next, the digital camera processor 507 converts the format of the scaled input image data from the format of red (R)-green (G)-blue (B) to the format of luminance-chroma (step S206). . Next, the digital camera processor 507 processes the input image data in relation to the resolution, the display position, and the like and performs filtering (step S207).

Next, the digital camera processor 507 temporarily stores the input video data in the dynamic RAM (504 in FIG. 3) (step S208).

Next, the digital camera processor 507 synthesizes the data temporarily stored in the dynamic RAM 504 of FIG. 3 and the On-Screen Display data (step S209). Next, the digital camera processor 507 converts the format of the synthesized image data from the format of luminance-chromaticity to the format of red (R) -green (G) -blue (B) (step S210). The video data of the format is output to the LCD driver 514 of FIG. 2 (step S211).

5 shows an algorithm of performing the shooting mode (step S4) of FIG. 1, 2, and 5, the algorithm of performing the shooting mode (S4) of Figure 3 will be described as follows. Here, the current position of the zoom lens is already set.

First, the digital camera processor 507 checks the remaining amount of the memory card (step S401) to confirm whether it is a capacity capable of storing the digital video signal (step S402). If it is not the capacity that can be stored, the digital camera processor 507 indicates that the capacity of the memory card is insufficient, and then ends the performance of the image capture mode (S41) (step S403). In case of storage capacity, the following steps are performed.

First, the digital camera processor 507 sets white parameters related to white balance by performing white balance setting according to currently set shooting conditions (step S404).

Next, in the automatic exposure (AE) mode (step S405), the digital camera processor 507 calculates the incident luminance, drives the aperture driving motor M _A in accordance with the calculated luminance, and sets the exposure time. (Step S406).

Next, in the automatic focusing mode (step S407), the digital camera processor 507 performs auto focusing to drive the focus lens (step S408).

Next, the digital camera processor 507 continues the following steps if the SH1 signal, which is the first stage signal from the shutter release button 13, is On (step S409).

First, the digital camera processor 507 checks whether the SH2 signal is on (step S410). If the SH2 signal is not on, the user does not press the second stage of the shutter release button 13 for capturing, so that the digital camera processor 507 repeats the steps S405 to S410.

If the SH2 signal is On, since the user has pressed the second stage of the shutter release button 13 for shooting, the digital camera processor 507 generates an image file on a memory card as a storage medium (step S411). ). The digital camera processor 507 then performs image capture (step S412). That is, the digital camera processor 507 receives the still image data from the CDS-ADC element 501. Next, the digital camera processor 507 compresses the received image data (step S413). The digital camera processor 507 stores the compressed image data in an image file (step S414).

FIG. 6 shows files stored in a memory card as a recording medium by performing the image capturing mode (step S4) of FIG.

Referring to Fig. 6, a folder " DCIM " for storing data files of a user is formed under the top-level folder " ROOT " created by formatting of a memory card.

Under this folder "DCIM", first and second folders "100SSCAM" and "101SSCAM" for storing files generated by the user's shooting operation are formed. Here, the name "100SSCAM" of the first folder includes the folder index "100" and the unique code "SSCAM". Similarly, the name "101SSCAM" of the second folder includes the folder index "101" and the unique code "SSCAM".

The unique code "SSCAM" is arbitrarily set in the manufacturing process of a digital image processing apparatus such as a digital camera. 900 image files are stored in the first folder "100SSCAM" in the order of creation, and 100 image files are stored in the second folder "101SSCAM" in the order of creation.

Here, the file index according to the file creation order is used together with the unique code "ABCD" to generate the file name. For example, the first file "ABCD0001.JPG" in the first folder "100SSCAM" is the file which was created first, and the 100th file "ABCD0100.JPG" in the second folder "101SSCAM" is the file which was created recently.

FIG. 7 is a flowchart illustrating an algorithm of performing a play mode S9 of FIG. 3. Referring to Figs. 1, 2, and 7, the algorithm of performing playback mode S9 of Fig. 3 will now be described.

First, the digital camera 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 S702). 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 S704), the digital camera 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 S706).

Next, when the tele-zoom button signal is generated by the user pressing the tele-zoom button 39 _T (step S708), the digital camera 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 S710).

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 a direction signal is generated by pressing 15 _U ) (step S712), the digital camera processor 507 controls the LCD driver 514 to move the display area of the enlarged image according to the generated direction signal (step S712). S714).

When the user generates a signal of the wide-zoom button 39 _W in this state of enlarged image (step S716), the digital camera processor 507 controls the LCD driver 514 to display the currently displayed file. Image is displayed on the color LCD panel 35 using the reference standard (step S718).

If the user generates a signal of the wide-zoom button 39 _W while the image is displayed in the reference standard (step S721), the digital camera processor 507 performs an index-playback mode (step S725). ). 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 S726), the digital camera processor 507 performs a file-management mode (step S727). Here, the file management means that after the files desired by the user are selected, deletion, copying, locking, and printing are performed on the selected files. Performing this file-management mode (step S727) will be described in more detail with reference to Figs. 6 and 8-10.

Steps S704 to S727 are repeatedly performed until the reproduction mode button 42 is pressed by the user (step S728).

8 is a flowchart showing an algorithm of performing a file-management mode (step S727) of FIG. 1, 2, 6, and 8, the algorithm of performing the file-management mode (step S727) of FIG. 7 will be described.

First, the digital camera processor 507 determines whether the user inputs a file-selection setting command to select a plurality of files (step S801).

If the file-selection setting is not made, if the user inputs a management execution command (step S801), the digital camera processor 507 manages the currently activated file (step S803). For example, according to the contents of the management execution command, the file currently deleted is deleted, copied, locked, or printed.

If the user inputs a file-select setting command to select a plurality of files (step S801), the digital camera processor 507 performs the following steps.

First, the digital camera processor 507 displays an index screen (one page of FIG. 10) including a thumbnail image of the currently activated file (step S804). In the present embodiment, nine thumbnail images are displayed on a single index screen.

Next, when the direction button signal is input by the user's operation (step S804), the digital camera processor 507 determines whether the signal input time is longer than 1 second (step S806). If the signal input time is shorter than or equal to 1 second, the digital camera processor 507 judges the input signal as one of the first direction-signals, and activates it as the adjacent thumbnail image of the currently active thumbnail image among all the thumbnail images. The cursor is moved (step S808). Here, the activation cursor is moved according to the direction of the input direction signal.

On the other hand, when the signal input time is longer than 1 second, the digital camera processor 507 judges the input signal as one of the second direction-signals, and performs a quick return operation (step S807). In this quick return operation, the activation cursor is moved to one thumbnail picture among the thumbnail pictures currently selected to be managed. Here, the activation cursor is moved according to the direction of the input direction signal. According to this quick return operation, after the user selects the target files to manage the files in the playback mode (step S9 in Fig. 3), it is possible to quickly cancel the selection of some of the selected files. This quick return operation will be described in more detail with reference to FIGS. 6, 9, and 10.

When step S807 or S808 is performed, the digital camera processor 507 determines whether a selection confirmation signal for the currently active file has been input by the user's operation (step S809). If the selection confirmation signal is input, the digital camera processor 507 determines whether the corresponding node number exists in the selection list (step S810).

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, since the first file "ABCD0001.JPG" in the first folder "100SSCAM" is the first file created, its node number is "1" and the 100th file "ABCD0100.JPG" in the second folder "101SSCAM" Is the most recently created file, which is the 1,000th file, so the node number is '1,000'. 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 camera processor 507 registers the node number in the selection list (steps S810 and S812). ).

On the contrary, when 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 camera processor 507 deletes the corresponding node number from the selection list (steps S810). And S811).

Next, if the user inputs a management execution command (step S813), the digital camera processor 507 manages the files of the node numbers registered in the selection list (step S814), and then performs the file-management mode ( Step S727) is terminated. For example, according to the contents of the management execution command, files of node numbers registered in the selection list are deleted, copied, locked, or printed.

On the other hand, if the user does not input a management execution command (step S813), the digital camera processor 507 repeats the steps from step S805 described above.

9 shows an algorithm of the fast return step S807 of FIG. FIG. 10 shows that the files of FIG. 6 are allocated to the index screens in the file-management mode (step S727) of FIG. In FIG. 10, T _n indicates a thumbnail image of an image file having a node number 'n'. 6, 9 and 10, the algorithm of the rapid return step (S807) of Figure 8 will be described as follows.

First, the digital camera processor 507 stores the node number of the movement target in the current node pointer in which the node number to which the activation cursor is to be moved is stored (step S901). Here, when the node numbers registered in the selection list are "800, 300, 20", and the index screen of page 89 is currently displayed, the node number of the moving target is "300".

Next, the digital camera processor 507 calculates the number of the moving-target index page to which the file of the moving-target number belongs (step S902). Here, if the number of moving-target index pages is N _PG , the moving-target number is N _ND , and the number of thumbnail images displayed in a single index screen of one page is N _TH , the number of moving-target index pages is N N. _PG is calculated by Equation 1 below.

Accordingly, as shown in FIG. 10, when the movement-target number N _ND is 300 and the number N _TH of thumbnail images displayed on the single index screen is 9, the number N _PG of the movement-target index page is 34.

Next, the digital camera processor 507 obtains the node number of the first file in the move-target index page (step S903). Here, the node number N _FF of the first file is calculated by Equation 1 below.

Accordingly, as shown in FIG. 10, if the number N _PG of the moving-target index page is 34 and the number N _TH of thumbnail images displayed on the single index screen is 9, the node number N _FF of the first file is 298.

Finally, the digital camera processor 507 displays the files of the move-target index page (step S904). That is, thumbnail images of nine files having node numbers 299 to 306 incremented by '1' from the node number N _FF 298 of the first file and the node number N _FF 298 of the first file are single. Display on the index screen.

As described above, according to the control method of the digital image processing apparatus according to the present invention, and the digital image processing apparatus using the method, the user activates one thumbnail image among the currently selected thumbnail images by a user's operation. The cursor is moved directly.
