The present invention relates to a photographing apparatus and a file classification method, and more particularly, to a photographing apparatus for storing an image file in a folder for each creation date, and checking a generation period between folders to provide a separate image file for each event. File classification method.

The imaging apparatus refers to a device capable of recording an image incident through a lens and reproducing and displaying already recorded images. Typical examples include a camera and a camcorder.

Images photographed by such a photographing apparatus are recorded in a file form, and the recorded files can be classified by folder unit. In this case, the file name, the folder name, and the folder structure may follow the DCF (Design rule for Camera File system) standard.

According to the DCF standard, the process of creating folder and file name is as follows. In order to record the captured image, it is first searched whether there is a 'DCIM' folder which is a root folder. As a result of the search, if there is no 'DCIM' folder, it is created, and '100SSDVC' which is a subfolder is created based on the DCF standard. The file to be recorded is named 'DCAM0001.jpg' according to DCF standard and classified into '100SSDVC' folder. Afterwards, if more files of 'DCAM0002.jpg' to 'DCAM9999.jpg' are generated and classified into the '100SSDVC' folder, the '101SSDVC' folder is further generated according to the DCF standard, and the images classified into the '101SSDVC' folder The file name of the file is also sequentially named 'DCAM0001.jpg' to 'DCAM9999.jpg' according to the DCF specification.

That is, up to 9999 files are classified into one folder according to the creation order, and when the number of files reaches 9999 or more, they are classified into a plurality of folders. However, since such file classification is a classification according to the created order, there is an inconvenience that a user needs to check and classify files in each folder one by one.

For example, in order to classify files photographed during a trip into one folder, it is troublesome to check image files of each file and determine whether they are photographed during the trip, and then move them to a separate folder.

In addition, when the files recorded on the photographing device are transferred to the PC, the folder structure transferred to the PC is also in accordance with the DCF standard, which is inconvenient for the user to separately reclassify a specific type of file group by folder.

The present invention has been proposed to achieve the above object, and an object of the present invention is to provide a recording device and a method for classifying a file that allows the user to conveniently check and manage the image file by separating the stored image file by the same event. In providing.

According to an aspect of the present invention, a photographing apparatus includes a photographing unit for photographing a subject to generate an image file, and storing the image file generated by the photographing unit in a folder corresponding to the creation date. And a control unit configured to compare the creation date of each folder provided in the storage unit, and classify folders having a difference between the creation dates within a preset range as the same event.

Preferably, a setting unit for setting a reference range for the event classification process, a folder generation unit for generating the folder by date under the control of the controller, and a text file recording the folder creation date, The apparatus may further include a text file generation unit added to the folder, and the controller may check a generation date of each folder using the text file added to each folder.

More preferably, the display may further include a display unit for displaying the classified events.

More preferably, the method may further include a transmission unit for transmitting the classified event to be displayed on an external device.

On the other hand, in the file classification method of the recording device according to another embodiment of the present invention, photographing a subject to generate an image file, storing the generated image file in a folder corresponding to the creation date, And comparing the creation dates of the stored folders, and classifying folders having a difference between creation dates within a preset range as being for the same event.

Preferably, the method may further include displaying each classified event.

More preferably, when the external device is connected, the method may further include transmitting the categorized event to the external device.

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

1 is a block diagram illustrating a configuration of a photographing apparatus according to an exemplary embodiment. According to FIG. 1, the photographing apparatus 100 includes a photographing unit 110, a storage unit 120, and a controller 130.

The photographing unit 110 photographs a subject to generate an image file. That is, the optical signal incident through the lens is photoelectrically converted into an electrical signal, and then an image file is generated through a predetermined signal processing process. The photographing unit 110 performing the above function may be implemented as a charge coupled device (CCD) and a signal processing unit for removing noise, adjusting gain, and converting an image file.

The storage unit 120 stores the image file generated by the photographing unit 110 in a folder corresponding to the creation date. That is, the storage unit 120 generates a folder for each creation date of the generated image file, and the image file having the same creation date is recorded in each folder. At this time, the folder name may be determined according to the DCF standard.

The controller 130 compares the creation date of each folder provided in the storage unit 120 and classifies the folders having the difference between the creation dates within a preset range as the same event. Since the image files generated in the same characters are recorded in each folder, the creation date of each folder is the same as the creation date of the stored image files.

When a play mode execution command is input or an external device such as a PC is connected, the controller 130 may check a preset range and classify each folder stored in the storage 120 according to the same event and transmit the same. Here, the playback mode is a mode for checking the image file generated by the photographing unit 110.

FIG. 2 is a block diagram illustrating in detail the configuration of the photographing apparatus of FIG. 1. According to FIG. 2, the photographing apparatus 100 includes the folder generator 140, the text generator 150, the setter 160, the display 170, and the transmitter 180 in the configuration of FIG. 1. It includes more. Meanwhile, functions of the photographing unit 110 and the storage unit 120 are the same as in FIG. 1, and thus will be omitted.

The folder generation unit 140 generates a folder by date under the control of the controller 130. In addition, the folder generation unit 140 generates a folder name of the generated folder and a file name of an image file stored in the folder. At this time, the generated folder name and file name may be generated according to the DCF standard, but it is preferable that only one image file generated in the same character is stored in one folder.

On the other hand, if there are more than 9999 image files generated in the same character, the folder generation unit 140 creates a new folder and stores the image files generated after the 9999th time.

The text generator 150 generates a text file that records the folder creation date and adds the text file to each folder generated by the folder generator 140.

That is, when an image file is generated through the photographing unit 110, the folder generator 140 generates a folder for storing the image file. In this case, the text generation unit 150 generates a text file that records the same date as the creation date of the image file and stores the text file in a corresponding folder. Accordingly, the same image file and the text file are stored in each folder, and each folder is stored in the storage unit 120. The structure of each folder stored in the storage unit can be confirmed through FIG. 3.

3 is a schematic diagram showing a folder structure according to an embodiment of the present invention. According to FIG. 3, when an image file is generated from the photographing unit 110, a search is made for a root folder DCIM (a) for storing the image file, and if there is no root folder DCIM (a), it is generated.

Assuming that the picture was taken on days 3, 4, 5, 7, 8, 12, 13, 14, and 15, if the number of video files recorded on each day does not exceed 9999, the root folder DCIM (a ), The subfolders b, b1, b2, b3, ..., b4, b5 are sequentially generated.

Each subfolder (b, b1, b2, b3, ..., b4, b5) has a text file (c, c1, c2, c3, ..., c4, c5) recording the created date and the image generated on that date. The files d, d1, d2, d3, ..., d4, d5 are stored.

In the storage unit 120, a first subfolder (b) is generated first, and a text file (c) is stored in the first subfolder (b), which is an image file (d) generated by the photographing unit (110). DCAM0001.JPG, DCAM0002.JPG, and DCAM0003.JPG are recorded sequentially.

That is, according to FIG. 3, the image file photographed on the 3rd day is stored in the 100SSDVC (b) folder, and it can be seen that the number of photographed photographs is 3 on the 3rd day.

The setting unit 160 sets a reference range for the event classification process. The setting unit 160 receives a user's selection using a selection key or a numeric key provided in the photographing apparatus 100 to set a reference range. Here, the reference range is for confirming whether the photographing was continuously performed during the reference range date.

When the reference range is input through the setting unit 160, the controller 130 checks the creation date of each folder by using the text file added to each folder and checks whether the shooting was continuously performed during the reference range date. That is, the creation date is compared through the text file of each folder, and folders within the reference range in which the difference between the creation dates is set are classified as the same event. A detailed description of the controller 130 for the classification process will be described with reference to FIGS. 4 and 5.

4 and 5 are schematic diagrams for explaining the file classification method of the photographing apparatus of the present invention. 4 and 5 are classified by events using the folder structure described in FIG. 3. On the other hand, the image file generated by taking a picture may be continuously generated in time according to events such as travel, meeting, birthday, vacation.

Specifically, if the user has been on a trip for four days, the user may take photographs continuously for four days or take an intermediate shot. In this case, the photographed picture has a continuity in a short range within 4 days. On the other hand, after returning from travel, the use of the photographing device becomes low. Thus, it is possible to classify the photos for 4 days having continuity into the same event. Alternatively, when shooting for another purpose after the trip, if the reference range is set in consideration of the date returned from the trip and the date to be photographed afterwards, it can be classified into different events.

Accordingly, it is possible to classify the pictures continuously taken for the same event by setting the reference range of the user.

4 is a schematic diagram for explaining the case where the reference range is set to one day. According to FIG. 4, the photographing date and the number of photographs taken at each photographing date are shown in a graph. That is, the number of image files stored in each folder generated by date.

Since the standard range is set to 1 day, pictures taken continuously from 3 days to 5 days can be classified as the first event 210. Since there are no pictures on 6 days and there are pictures taken on 7 days and 8 days, 5 The difference between the date of creation and the seventh day is outside the reference range 1. Accordingly, pictures taken on the 7th and 8th days are classified as the second event 220. Meanwhile, the pictures taken on the 12th to 15th days may be classified as the third event 230.

5 is a schematic diagram for explaining the case where the reference range is set to two days. In FIG. 5, events are classified in the same manner as in FIG. 4.

That is, since the reference range is set to 2 days, pictures taken up to 3 to 8 days may be classified as the first event 310, and pictures taken on 12 to 15 days are converted to the second event 330. You can sort.

The controller 130 may classify the image files stored in each folder for each event. Specifically, when the playback mode selection command is input, the display unit 170 is controlled to display image files classified by events. Alternatively, when the connection of the external device 10 is recognized, the transmission unit 180 may transmit the image file classified for each event to the external device. Accordingly, the external device 10 can check the image file classified by event.

Here, the external device 10 may be any storage medium capable of storing image files such as an optical recording medium such as a CD or a DVD, a hard disk, a memory stick, or the like.

Specifically, each of the classified events may be given a name so that the corresponding folders may be displayed when a predetermined event is selected, and all of the corresponding image files may be displayed when one of them is reselected. Alternatively, when a predetermined event is selected, all the video files may be displayed immediately. The same can be handled in the case of transmission.

6 is a flowchart illustrating a file classification method of a photographing apparatus according to an exemplary embodiment. According to FIG. 6, when an image file is generated by photographing a subject (S610), the generated image file is stored in a folder corresponding to the creation date (S620). At this time, only the image file created in the same character is stored in each folder. In addition, each folder stores a text file that records the same date as the creation date of the image file as the folder creation date.

By comparing the creation date of each folder (S630), folders having a difference between the creation dates within a predetermined range are classified as being for the same event. That is, when comparing the folder creation date in sequence, the folder whose creation date is within the preset range is classified as the same event (S650), and the folder which is out of the preset range is classified as the new event (S660). Accordingly, each classified image file may be displayed for each event or transmitted to an external device according to a user's selection.

As described above, according to the present invention, the image file may be classified according to the same event by checking the generation period of the folders stored by the creation date. Accordingly, the user may check the image files classified by the same event without checking the image files one by one and classifying them by the same event. In addition, user convenience may be increased by classifying and transmitting the self-stored image file for each event when the external storage medium is connected.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the above-described specific embodiment, the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or prospect of the present invention.
