The present invention relates to a method of operating a digital image processing apparatus, and more particularly, to a method of changing a folder name, a folder name and a file name, and a file name stored in the device.

Digital image processing apparatuses vary from manufacturer to manufacturer, but when an image is captured, the digital image processing apparatus may include a 100SSCAM folder to a 999SSCAM folder, and may store sa700001.jpg files to sa709999.jpg files in each folder.

When an image is captured by the digital image processing apparatus, the captured image is stored as follows.

first. The image is numbered with the next number taken before. For example, if the number of previously shot images was sa700004.jpg file in the 101SSCAM folder, the next time the image was taken, it is stored as sa700005.jpg file in the 101SSCAM folder.

Second, give the number after the last number currently on the memory card. For example, if the sa700004.jpg file in the 101SSCAM folder was the last image, the next image is saved as the sa700005.jpg file in the 101SSCAM folder.

Third, create a new folder next to the current folder number and give it a number from 1. For example, if the sa709999.jpg file in the 101SSCAM folder was the last image, the next image is saved as the sa700001.jpg file in the 102SSCAM folder.

When the number is set in the image in the manner as described above, the number may be omitted in the middle. For example, as shown in FIG. 1, when the sa700004.jpg file in the 101SSCAM folder lasts in memory card 1 and the sa709987.jpg file in the 999SSCAM folder lasts in memory card 2, If you change the image to memory card 1 while recording, the 999SSCAM folder and sa709988.jpg file are created in the memory card 1, and there are no intermediate folders from 102SSCAM folder to 998SSCAM folder. .

In this way, if an image is captured by skipping a folder number in the middle, a situation in which no more images can be taken is generated because a small number of image files are generated up to sa709999.jpg file in the 999SSCAM folder.

That is, when 999 folder 9999 files are stored in the state where there are few images, shooting is not possible because folders and files can no longer be created. If you have a different memory card, you can change the memory card to shoot, but if there is no extra memory card to go outdoors, or if you can not use a PC, there is a problem that can not be taken further.

The technical problem to be achieved by the present invention is to allow users to directly access the memory card to change the folder name, folder name and file name and file name in accordance with the standard in order to avoid the storage space of the memory card by skipping the intermediate folder The present invention provides a method of changing a folder name and / or a file name in a digital image processing apparatus.

In the digital image processing apparatus for solving the above technical problem to be solved by the present invention, (a) when the folder name change signal is received, change an arbitrary folder name to a selected folder name. Changing the remaining folders in ascending order of folder names; (b) when the folder name and file name change signal is received, change any folder name and any file name within the folder to the selected folder name and file name, change the file names of the remaining files in ascending order, Changing a folder name and file names of the files in the folder in ascending order; And (c) when the file name change signal is received, changing any file name existing in the current folder to the selected file name, and changing the file names of the remaining files in ascending order.

In the present invention, when changing the folder name, among the folder name consisting of 3 digits + 5 alphanumeric mixed characters, the 3 digits are changed to an arbitrary number.

In the present invention, when changing the file name, the four-digit number is changed to an arbitrary number among file names consisting of four alphanumeric + four-digit numbers.

In the present invention, step (a) comprises the steps of: (a-1) searching for and displaying the total number of folders stored in the device; (a-2) changing the three digits to an arbitrary number by selecting a first folder among the plurality of folders; And (a-3) changing the three digits of the remaining folders in ascending order.

In the present invention, step (b) comprises the steps of: (b-1) searching for and displaying the total number of folders stored in the device; (b-2) selecting the first folder among the plurality of folders and changing the three digits to an arbitrary number; (b-3) changing the fourth digit to an arbitrary number by selecting a first file among the files in the changed folder; (b-4) changing the four digits of the remaining files in ascending order; And (b-5) changing the three digits of the remaining folders and the four digits in the folder in ascending order.

In the present invention, step (c) comprises: (c-1) retrieving and displaying the total number of files stored in the current folder; (c-2) selecting the first file of the files and changing the four digits to an arbitrary number; And (c-3) changing the four digits of the remaining files in ascending order.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

2 is a block diagram showing a configuration of a digital image processing apparatus according to the present invention, wherein the user input unit 240, the imaging unit 210, the image processing unit 220, the display unit 230, the memory card 240, and the DSP are shown. (Digital signal processor) 250 is included.

Although not shown in the drawing, the user input unit 200 may include a shutter release button that opens and closes to expose the CCD or film to light for a predetermined time, and a function button that inputs to execute various menus related to the operation of the digital image processing apparatus. For example, a wide-angle zoom button or a tele-zoom button may be used to widen the angle of view or narrow the angle of view according to an input.

The imaging unit 210 includes a shutter, a lens unit, an aperture, a charge coupled device (CCD), and an ADC, which are not shown in the figure.

The shutter is a mechanism for adjusting the amount of light exposed together with the aperture. The lens unit receives light from an external light source and processes an image. At this time, the iris adjusts the amount of light incident (light quantity) according to the degree of opening and closing. The opening and closing degree of the iris is controlled by the DSP 250.

The CCD accumulates the amount of light input through the lens unit and outputs an image captured by the lens unit in accordance with the accumulated light amount in accordance with the vertical synchronization signal. Image acquisition of the digital image processing apparatus is performed by a CCD that converts light reflected from a subject into an electrical signal. In order to obtain a color image using a CCD, a color filter is required, and most of them employ a filter (not shown) called a color filter array (CFA). CFA has a structure arranged regularly by passing only one color light per pixel, and has various shapes according to the arrangement structure. The ADC converts an analog video signal output from the CCD into a digital signal.

The image processor 240 performs signal processing to display a digitally converted image signal. Devices used in CCD and CFA filters are sensitive to changes in temperature and generate a dark current according to the changed temperature, which includes an unwanted black level in the image signal. Accordingly, the image processor 240 removes the black level generated by the dark current as described above.

The image processor 240 also performs gamma correction. Since human vision reacts nonlinearly to brightness according to Weber's law, when a limited bit depth is given, linearly recording light brightness results in posterization. ) Occurs. Therefore, in order to show the maximum image quality under a given bit depth, it is necessary to encode using a nonlinear function. In this way, encoding information according to nonlinearity of human vision is called gamma correction. The gamma correction of the image processor 240 gamma corrects and outputs the video signal input by the gamma curve. For example, the input luminance level of the 12-bit image signal is corrected to 8-bit luminance level.

The image processor 240 performs CFA interpolation to interpolate the Bayer pattern implemented by the RGRG line and the GBGB line of the gamma corrected predetermined data into the RGB line. The CFA interpolation of the image processor 240 first reconstructs the G channel from the pixels having only the R or B channel value, and then fills the empty values in the order of the B channel, the R channel, or the R channel, the B channel in order to R, G, B Restore three channels.

The image processor 240 converts the interpolated RGB signal into a YUV signal, filters the Y signal by a high-band filter, and sharpens the image. The image processor 240 uses the standard color coordinate system to adjust the color values of the U and V signals. Perform color correction to correct and remove their noise.

The image processor 240 generates a JPEG file by compressing and signal-processing Y, U, and V signals from which noise is removed, and the generated JPEG file is displayed on the display unit 230, and the memory card 240 is selected by a user. )

All operations of the image processor 240 operate under the control of the DSP 250.

DSP 250, as shown in Fig. 3A, provides a menu for changing folder names and file names. This is selected by the user, and selecting this menu allows the user to randomly change the folder name and / or file name sequentially.

When the folder name menu is selected in FIG. 3A, the DSP 250 provides a submenu for changing both the folder name and the subfile name, as shown in FIG. 3B.

Next, a method of changing a folder name and / or a file name in the digital image processing apparatus will be described in detail with reference to FIGS. 4 to 7. The method for changing a folder name and / or file name according to the present invention may be performed inside a control apparatus for a digital image processing apparatus as shown in FIG. 2. It may be performed inside the DSP 250 with the help of the components.

In general, the folder name is composed of <3 digits + 5 alphanumeric characters>, the file name is composed of <4 alphanumeric characters + 4 digits>, and the name of the folder and file name that consists only of numbers. Because they are stored separately, the same number should not exist. Up to 999 folders and up to 9999 files per folder are created.

First, when a user selects a name change menu to change a folder name, folder name and file name, and file name, the DSP 250 provides a name change menu as shown in FIG. 3A (step 401).

The DPS 250 outputs a name change menu as shown in FIG. 3A to change the folder name or the file name (step 402).

If the folder name is changed among these, the DPS 250 outputs a submenu as shown in FIG. 3B, whether only the folder name is changed or all subfile names together with the folder name.

When the user selects a menu for changing only the folder name from FIG. 3B, the DSP 250 searches for the total number of folders stored in the memory card 240 and displays it on the display 230 (step 404). For example, it is assumed that the total number of folders stored in the memory card 240 is 121SSCAM, 155SSCAM and 999SSCAM as shown in FIG. 5A.

The user looks at the total number of folders displayed on the display 230, selects the first folder, and changes <3 digits> of the folder name consisting of <3 digits + 5 alphanumeric characters> to "100." Then, the DSP 250 performs a folder name change operation according to a user input in step 405. For example, in FIG. 5A, 121SSCAM is selected as the first folder, and &quot; 3 digits " " 121 " With this change, the folder name 121SSCAM is changed to 100SSCAM as shown in Fig. 5B.

Thereafter, the DSP 250 sequentially changes &quot; three digits &quot; among folder names of other folders in ascending order from " 101 " (step 406). In FIG. 5A, the remaining folders 155SSCAM and 999SSCAM are changed to 101SSCAM and 102SSCAM in ascending order as shown in FIG. 5B.

The folder name can be changed in the above manner. However, when changing the folder name, there may be a case in which there is a folder with the same folder number in the memory card 240, that is, the name is not changed because the name to be changed and the existing name are the same. In this case, change the number by sequentially increasing the number only for the folder with the same number, change the last folder name first, and then change the folder name in descending order for the remaining folders. For example, when the folders stored in the memory card 240 are 100SSCAM and 100ABCDE, as shown in FIG. 6A, if 100ABCAM is attempted to be 100SSCAM, the name is not changed since 100SSCAM exists. In this case, as shown in FIG. 6B, first, 100SSCAM is changed to 101SSCAM, and then 100ABCDE is changed to 100SSCAM as shown in FIG. 6C.

For files, files with the same number are treated with the same number. For example, if the sa700011.jpg and sa700011.wav files are present, change both to the same number sa700001.jpg and sa700001.wav.

When the user selects a menu for changing all of the lower file names together with the folder name from FIG. 3B, the DSP 250 searches for the total number of folders stored in the memory card 240 and displays them on the display 230 (407). step). For example, it is assumed that the total number of folders stored in the memory card 240 is 121SSCAM, 155SSCAM and 999SSCAM as shown in FIG. 7A.

When the user sees the total number of folders displayed on the display 230, selects the first folder and changes the <3 digits> from the folder name consisting of <3 digits + 5 alphanumeric characters> to "100". The DSP 250 performs a folder name change operation according to a user input (step 408). For example, in FIG. 7A, 121SSCAM is selected as the first folder, and &quot; three digits &quot; " 121 " With this change, the folder name 121SSCAM is changed to 100SSCAM as shown in FIG. 7B.

Thereafter, the DSP 250 searches for all the sub-files stored in the folder of 100SSCAM and displays them on the display 230. The user views the total number of files displayed on the display 230, selects the first file, and selects < If <number 4 digits> of the file name consisting of alphanumeric mixed 4 digits + 4 digits> is changed to "0001", the DSP 250 performs a file name change operation according to a user input (step 409). For example, if the sub-files stored in 100SSCAM in FIG. 7B are sa700004.jpg, sa700005.jpg, and sa700999.jpg, select sa700004.jpg as the first file and select <0004 digits> "0004". Change to " With this change, the file name sa700004.jpg is changed to sa700001.jpg as shown in Fig. 7C.

Subsequently, the DSP 250 sequentially changes <4 digits> of the file names in ascending order from “0002” with respect to the remaining files in the renamed folder. In FIG. 7B, the remaining files sa700005.jpg and sa700999.jpg are changed to sa700002.jpg and sa700003.jpg in ascending order as shown in FIG. 7C.

Thereafter, the DSP 250 changes <three digits> of the unchanged folder names in ascending order from "101", and sequentially changes lower files in the corresponding folder in ascending order from "0001" (step 411). In FIG. 7C, the remaining folders 155SSCAM and 999SSCAM are changed to 101SSCAM and 102SSCAM in ascending order as shown in FIG. 7D. At the same time, the subfiles stored in the changed folders 101SSCAM and 102SSCAM are also renamed. When changing the file name, as described above, when changing the <4 digit number> of the first file name to "0001", the <4 digit number> in the file name is sequentially ordered from "0002" to the remaining plurality of files. Change it. In addition, since the first <file number> of the first file name is changed to "0001", the file name having the smallest number can be automatically sorted from the file name having the smallest number to "0001" afterwards.

If the user selects a menu for changing only a file name from FIG. 3A, the DSP 250 searches for the number of lower files in the current folder stored in the memory card 240 and displays the number of lower files in the display 230 (step 412). ). For example, assume that the number of files stored inside the current folder is sa700009.jpg, sa700010.jpg, and sa700099.jpg, as shown in FIG. 8A.

Then, when the user views the total number of files displayed on the display 230 and selects the first file and changes the <number 4 digits> of the file name consisting of <alphanumeric mixed 4 digits + number 4 digits> to "0001", The DSP 250 performs a file name change operation according to a user input (step 413). For example, in FIG. 8A, sa700009.jpg is selected as the first file, and <number of 4 digits> "0009" is changed to "0001".

Subsequently, the DSP 250 sequentially changes <4 digits> of the file names in ascending order from " 0002 " for the remaining files in the renamed folder. In FIG. 8A, the remaining files sa700010.jpg and sa700099.jpg are changed to ascending sa700002.jpg and sa700003.jpg as shown in FIG. 8B.

As described above, according to the present invention, the user can directly access the memory card to change the folder name, the folder name and the file name and file name in accordance with the standard, so as to prevent the memory card from running out of storage space by skipping the intermediate folder Can be.

Also, when the user wants to change the folder name and / or file name in sequence, the user can simply change it without changing it.
