In this case, the first region may be positioned before the file name, and the second region may be positioned after the first region. In addition, the first region may be four-digit character information, and the second region may be four-digit numeric information.

In this case, the file name may be specified such that the edited content is included in the file name of the image file which is edited and newly stored according to the edited content. For example, the editing information may be at least one of color change, sticker addition, photo frame application, image rotation, resolution change, red eye removal, brightness adjustment, contrast change, and out focusing application.

That is, when creating a new file by editing special effects, etc., the saved image file is marked so that it is possible to distinguish what edit is made by using the first four digits of the first area. Can be stored as

Accordingly, it is possible to distinguish between the original image file and the edited image using only the file name. In addition, the first three digits of the four digit character information of the first region may be used to display model information of the digital image processing apparatus, and the other three digits may be used to display an image edit added to the original image to be distinguishable.

In this case, the image files including the numeric information of the same second region and the character information of the other first region may be displayed as image files changed from the same original image file.

Therefore, it is possible to know what image processing is performed on the corresponding image file using only the file name. The file name may include model information of the digital image processing apparatus, file editing information, and the like.

In the storing step S570, an image file may be stored under a file name. In this case, the original image file may be preserved without being deleted, and a new file name may be assigned to the edited image file, and the edited image file may be stored.

According to the present invention, it is possible to efficiently manage the image files by including the information on the image file in the file name attached to the stored image file.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, it is merely an example, and those skilled in the art may realize various modifications and equivalent other embodiments therefrom. I can understand. Accordingly, the true scope of protection of the invention should be defined only by the appended claims.
