That is, when creating a new file by editing special effects or the like in a stored image file, the first four-digit first area is used to indicate which edition has been made so as to be distinguishable, and the subsequent serial number is the same number as the original . ≪ / RTI >

Accordingly, it is possible to distinguish the original image file from the edited image by only the file name. In addition, the former three characters among the four-character information of the first area may be used to display the model information of the digital image processing apparatus, and the remaining one digit may be used to distinguish the image editing added to the original image.

At this time, it is possible to indicate that the image files including the numerical information of the same second area and including the character information of the first area are changed image files from the same original image file.

Therefore, it is possible to know which image processing has been performed on the image file by the file name alone. The file name may include model information of the digital image processing apparatus, file editing information, and the like.

In the storing step (S570), the image file can be stored as a file name. At this time, it is possible to designate a new file name in the edited image file and save the edited image file while preserving the original image file without deleting it.

According to the present invention, image files can be efficiently managed by including information about the image file in the file name attached to the stored image file.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, You will understand. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.

FIG. 1 is a view showing the external appearance of a digital camera according to an embodiment of the digital image processing apparatus according to the present invention.

FIG. 2 is a block diagram schematically illustrating a control device that may be included in the digital camera of FIG. 1. Referring to FIG.

3 is a block diagram schematically illustrating a digital image processing apparatus according to a preferred embodiment of the present invention.

4 is a flowchart schematically showing a control method of a digital image processing apparatus according to a preferred embodiment of the present invention.
