Abstract

A digital image processing apparatus capable of reducing the number of calculations performed when a new image file satisfying a DCF standard generated for a captured image is edited, so as to reduce the time required for performing the edit, and a file managing method performed in the digital image processing apparatus. The digital image processing apparatus includes a digital signal processing unit which generates a file having a grouping attribute for a captured image and changes the grouping attribute of the file during a group edit of a selected file.

Claims

1. A digital image processing apparatus comprising a digital signal processing unit which generates a file having a grouping attribute for a captured image and changes the grouping attribute of the file during a group edit of a selected file.

2. The digital image processing apparatus of claim 1, wherein the digital signal processing unit designates the grouping attribute to one of the characters of a file name based on a design rule for camera file system (DCF) standard.

3. The digital image processing apparatus of claim 1, wherein the digital signal processing unit records the grouping attribute in a user definition area of the file, which includes photographing information about the captured image.

4. The digital image processing apparatus of claim 2, wherein the digital signal processing unit performs at least one of a group edit of adding a file to a group, a group edit of moving a file between groups, and a group edit of deleting a file from a group.

5. The digital image processing apparatus of claim 3, wherein the digital signal processing unit performs at least one of a group edit of adding a file to a group, a group edit of moving a file between groups, and a group edit of deleting a file from a group.

6. The digital image processing apparatus of claim 4, wherein when the digital image processing apparatus is powered off, the digital signal processing unit updates an index file, which includes location information and photographing information on the files included in the group, with the results of the edit, or updates the user definition area with the results of the edit.

7. The digital image processing apparatus of claim 5, wherein when the digital image processing apparatus is powered off, the digital signal processing unit updates an index file, which includes location information and photographing information on the files included in the group, with the results of the edit, or updates the user definition area with the results of the edit.

8. A digital image processing apparatus comprising:

a file generating unit generating a file having a grouping attribute for a captured image;

an editing unit performing a group edit of adding a selected file to a group, a group edit of moving the selected file between groups, or a group edit of deleting the selected file from a group; and

a file changing unit changing the grouping attribute of the file on which the group edit has been performed.

9. The digital image processing apparatus of claim 8, wherein the file generating unit designates the grouping attribute to one of the characters of a file name based on a design rule for camera file system (DCF) standard.

10. The digital image processing apparatus of claim 8, wherein the file generating unit records the grouping attribute in a user definition area of the file, which includes photographing information about the captured image.

11. The digital image processing apparatus of claim 9, further comprising an information updating unit which, when the digital image processing apparatus is powered off, updates an index file which includes location information and photographing information on the files included in the group, with the results of the edit, or updates the user definition area with the results of the edit.

12. The digital image processing apparatus of claim 10, further comprising an information updating unit which, when the digital image processing apparatus is powered off, updates an index file which includes location information and photographing information on the files included in the group, with the results of the edit, or updates the user definition area with the results of the edit.

13. A digital image processing apparatus comprising a digital signal processing unit which designates a grouping attribute to one of the characters of a file name based on a design rule for file system (DCF) standard and changes the grouping attribute of the file name upon at least one of an addition of a selected file to a group, a transfer of the selected file between groups, and a deletion of the selected file from a group.

14. The digital image processing apparatus of claim 13, wherein when the digital image processing apparatus is powered off, the digital signal processing unit updates an index file which includes location information and photographing information on the files included in the group, with the results of the change.

15. A digital image processing apparatus comprising a digital signal processing unit which records a grouping attribute in a predetermined area of a captured file and changes the grouping attribute recorded in the file upon at least one of addition of a selected file to a group, a transfer of the selected file between groups, and a deletion of the selected file from a group.

16. The digital image processing apparatus of claim 15, wherein the area in which the grouping attribute is recorded is a user definition area of the file, which includes photographing information on the file of the captured image.

17. The digital image processing apparatus of claim 16, wherein when the digital image processing apparatus is powered off, the information updating unit updates the user definition area with the results of the change.

18. A file managing method performed by a digital image processing apparatus, comprising the operations of:

generating files having grouping attributes for captured images;

performing an edit of adding a file selected from the files to a group, an edit of moving the selected file between groups, or an edit of deleting the selected file from a group; and

changing the grouping attribute of the selected file when the edit is completed.

19. The file managing method of claim 18, further comprising the operation of, when the digital image processing apparatus is powered off, updating an index file, which includes location information and photographing information on the files included in the group, with the results of the change.

20. The file managing method of claim 18, wherein the generating includes designating the grouping attribute to one of the characters of a file name based on a design rule for camera file system (DCF) standard.
