The present invention relates to an image storing method of a digital imaging apparatus, and more particularly, to an image storing method of a digital imaging apparatus capable of selecting a folder in which photographed images are to be stored.

In general, a camcorder or a digital camera converts an image incident through a lens into an electrical signal using a charge coupled device such as a charge coupled device (CCD), and then stores a memory device such as a semiconductor memory device or a magnetic tape. It is a digital imaging device to store on.

Digital video cameras are digital still cameras (DSCs) that take large intermittent images and store them in semiconductor memory devices, and digital video cameras that take images continuously and store them in storage media such as magnetic tape. : DVC).

When a user captures a specific image using a digital imaging device such as a DSC or a DVC, the image is stored in a portable storage medium such as a semiconductor memory device or a magnetic tape in the digital imaging device. The process of storing the captured image in the removable storage medium is as follows.

First, when the image captured by the CCD is converted into an electrical signal, whether the portable storage medium is present in the digital imaging apparatus is checked. If there is a removable storage medium, it is determined whether there is a folder for storing the captured image file in the removable storage medium. If the folder to be saved does not exist, create a new folder and save it. If the folder exists, select and save the last created folder among the created folders. At this time, it is assumed that there is space in the final folder to store newly photographed image files. In addition, the file name of the newly captured image file is automatically set in the order of being stored in the folder.

The name of the folder created in the removable storage medium and the name of the file stored in each folder are set according to a predetermined convention set by each manufacturer, and the user cannot change it arbitrarily.

However, if the captured images are stored in the folder in the order in which they were taken, regardless of whether they are movie files or still image files, the folder created in the portable storage It was inconvenient to create a folder on the PC and load and reclassify the image files accordingly.

Also, with the recent increase in the number of images taken with the expansion of DSC and DVC, the number of images taken is absolutely increased. In order to find an image, there is a problem that it is cumbersome because all the stored images must be searched in the order in which they were recently taken and stored.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an image storing method of a digital imaging apparatus that can select a folder in which a corresponding image is stored when storing an image captured by the digital imaging apparatus.

Another object of the present invention is to provide an image storage method of a digital imaging apparatus that can configure a file classification form of a removable storage medium storing captured images according to a user's taste.

The present invention for achieving the above object is characterized in that the storage is selected in the storage space of the storage medium of the storage medium, when the edit storage mode selection for editing and storing the image taken by the digital imaging device.

In addition, when the photographed image is stored in the selected storage space, when the maximum storage capacity of the selected storage space is exceeded, a new storage space is created in the storage medium, and the captured image is stored in the new storage space. It features.

If there is no selected storage space, a new storage space is created in addition to the storage space, and the captured image is stored in the new storage space.

Also, when the captured image is stored in the automatic storage mode, the captured image is stored in a storage space generated at the end of the storage space.

In addition, the storage medium is a memory stick, a removable storage medium, characterized in that the SD card.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 is a view illustrating a digital imaging apparatus according to an embodiment of the present invention. The illustrated digital imaging apparatus includes a lens 120 that enlarges and transmits a light source of a subject and a charge that converts an optical signal of the subject into an electrical signal. A Charge Coupled Device (CCD) 130, a Digital Signal Processing Unit (DSP) 140 for converting pixel information input to the CCD 130 into digital signals and processing them into image data; A microcomputer 100 for calculating the output signal of the 140 and controlling the entire system, a compression unit 150 for compressing still image or moving image data, and an image DRAM for temporarily storing the compressed image information (Dynamic Random). Access Memory) 170, a removable storage medium 180 for finally storing the image information temporarily stored in the image DRAM 170 on a single image information card, and a display unit 160 displaying the captured image on the screen. Wow, D And a key input unit 110 for inputting various commands related to the operation of the digital imaging apparatus.

The compression unit 150 compresses the size of the image data by compressing the image data into formats of Joint Photographic Coding Experts Group (JPEG), Moving Picture Experts Group (MPEG), and Motion-JPEG (MJPEG) according to whether the image data is related to a still image or a moving image. Reduce.

The removable storage medium 180 of the DSC or DVC uses a flash memory card that is a nonvolatile memory. The types of memory cards are Compact Flash (C / F: Compact Flash type), Micro Drive (MD: Microdrive), SD (Secure Digital) card, MMC (Multi Media Card), Memory Stick, SMC (Smart Media) Card), and different types of memory cards are used by each manufacturer.

When the user captures a desired image with a digital imaging apparatus, the photographed subject is converted into an electrical signal while passing through the lens 120 and the CCD 130, and then converted into a digital signal through the DSP 140. The data converted into a digital signal is compressed by the compression unit 150 in conformity with the JPEG, MPEG or MJPEG format under the control of the microcomputer 100. The compressed data is temporarily stored in the image DRAM 170 and finally stored in the removable storage medium 180, that is, the memory card. In this case, the microcomputer 100 displays the display unit 160 before storing the data. ) To display a screen where you can select the space where the data will be stored.

This is a function to classify the captured image according to a user's preference, and as shown in FIG. 2, the folder set by the user may be checked through the display unit 160. The user may classify the space for storing the captured image on the removable storage device 180 in various ways. As shown in the display 160, the user may classify the storage folder by work, travel, friends, family, etc. by the theme, or the video. You can choose from several methods, such as classifying them as still images and classifying them as date taken.

When the newly captured image is selected from one of the previously set folders (for example, a travel folder) by operating the key input unit 110 and stored in the corresponding folder or creating a separate storage space. In this case, you can create and save additional folders.

Hereinafter, an image storing method of a digital imaging apparatus according to an embodiment of the present invention will be described with reference to FIGS. 3A and 3B.

First, if a user wants to photograph a specific subject and manipulates the key input unit 110 to photograph the subject, the light source of the subject is stored through the lens 120, the CCD 130, the DSP 140, and the compression unit 150. It is compressed in a suitable format and stored in the image DRAM 170. (S100) In order to finally store the image data stored in the image DRAM 170 in the removable storage medium 180, the microcomputer 100 is removable in the digital imaging apparatus. Check whether the storage medium 180 exists, the type, specification, etc. of the removable storage medium 180 (S110).

If it is determined whether the removable storage medium 180 is present (S120) and not inserted into the digital imaging apparatus, the storage process is terminated as it cannot be stored. If the removable storage medium 180 exists, a screen for selecting whether or not to edit the display is displayed on the display unit 160 (S130).

When the user does not select the edit storage, that is, in the case of automatic saving, first, the storage state of the removable storage medium 180 is checked first (S140). The previously photographed image is stored in the current removable storage medium 180. To recognize information about the state of being present.

In addition, the microcomputer 100 determines whether at least one folder capable of storing an image is created in the removable storage medium 180 (S150). If there is a folder that exists, the last created folder among the existing folders is determined. (S160)

Check the amount of data currently stored in the selected folder. (S170) It is determined whether the currently stored capacity is smaller than the total capacity of the folder that is less than the amount of the new video to be saved. ) If the storage capacity is smaller, there is room for the storage space, and thus, the newly captured image data is stored in the selected folder. (S190) The file name of the image data to be stored is a certain number determined according to the order of storing the selected image data. It is set automatically.

If none of the folders are created in the removable storage medium 180 in step 150 or if it is determined that there is not enough storage capacity in the selected folder in step 180 to store a new image, a new folder is automatically generated (S200). The captured image data is stored in a new folder (S210). In this case, the new folder name and the file name of the image data to be stored are automatically determined by a specific number according to a predetermined rule set by the device.

On the other hand, if the user selects the edit and save in step 130, and proceeds to the edit and save shown in Figure 3b. The microcomputer 100 controls the display unit 160 to display the edit folder set up to date by the user. In addition, it is determined whether the user has instructed through the key input unit 110 to create a new edit folder in addition to the existing edit folder.

When it is determined that the user wants to save the existing edit folder, the user checks the folder selected by the user among the existing edit folders displayed on the display 160 (S310). The capacity of the image data currently stored in the selected folder is checked. (S320) It is determined whether the currently stored capacity is smaller than the capacity of the newly captured image data from the total capacity that can be stored in the selected folder. (S330) If the stored capacity is small, newly photographed in the selected folder. One image data is stored (S340).

If it is determined in step 300 that the user wants to create a new folder or if the new image data cannot be stored because the capacity of the selected folder is large in step 330, a new edit folder is created. The screen is displayed on the display unit 160 so that the name of the edit folder can be input by operating the input unit 110. (S360) If the user inputs a folder name, the user saves with the corresponding name and then enters a new edit folder. The newly captured image data is stored. (S370)

In this way, the user may not only set the digital imaging apparatus to automatically classify and store the images, but also allow the user to select a format in which the images are stored in the removable storage medium.

In the present invention, only the process of storing the image taken by the digital imaging apparatus is referred to. However, when the image stored in this manner is to be reproduced by the digital imaging apparatus, in addition to being played in the reverse order from the recently photographed image, Of course, it is possible to select a folder to be played among the folders stored in the storage medium so as to play the desired video first.

As described in detail above, in the present invention, in storing an image photographed by a digital imaging apparatus, a storage form may be variously configured according to a user's preference in a removable storage medium in which an image is stored, and a folder to be stored may be It can be selected and saved, providing users with a variety of choices and saving them from having to sort files again via a PC.

In addition, it is possible to provide a digital image device that can be variously adapted to the user's preferences because it can be stored in a desired manner among the automatic storage method and the edit storage method.
