Abstract

The file name of an image file as a saving target is acquired (S401). A hash value is calculated on the basis of the acquired file name (S402). The image file as the saving target is saved in association with the data of the hash value.

Claims

1. An image processing apparatus for storing an image in a recording medium, comprising:

acquisition means for acquiring identification information to identity an image file in storing the image file in the recording medium;

calculation means for calculating a hash value on the basis of the identification information; and

storage control means for controlling to store the image file in the recording medium in association with the hash value.

2. The apparatus according to claim 1, wherein said acquisition means acquires, as the identification information of the image file, one of a file name of the image file and a full path name representing a recording location of the image file in the recording medium.

3. The apparatus according to claim 1, wherein said calculation means calculates the hash value on the basis of character codes of a character string in which characters of the identification information are unified in one of an uppercase and a lowercase.

4. The apparatus according to claim 1, wherein said storage control means controls to store the hash value in a directory entry corresponding to the image file.

5. The apparatus according to claim 1, further comprising:

input means for inputting a file name of an image file as a search target;

second calculation means for calculating a hash value on the basis of the file name input by said input means;

search means for searching for a file name of an image file stored in the recording medium in association with a hash value which coincides with the hash value calculated by said second calculation means; and

reading means for reading out the image file with the file name found by said search means when a character string of the file name found by said search means coincides with the character string input by said input means.

6. The apparatus according to claim 5, wherein said second calculation means calculates the hash value on the basis of character codes of a character string in which characters of the identification information are unified in one of an uppercase and a lowercase.

7. An image processing method of storing an image in a recording medium, comprising:

an acquisition step of acquiring identification information to identity an image file in storing the image file in the recording medium;

a calculation step of calculating a hash value on the basis of the identification information; and

a storage control step of controlling to store the image file in the recording medium in association with the hash value.

8. A program causing a computer to execute an image processing method of claim 7.

9. A computer-readable storage medium storing a program of claim 8.

10. An image processing method of storing an image in a recording medium, comprising:

an identification information acquisition step of acquiring identification information to identity an image file in storing the image file in the recording medium;

a file information acquisition step of acquiring file information of the image file;

a calculation step of calculating a hash value on the basis of the identification information and the file information; and

a storage control step of controlling to store the image file in the recording medium in association with the hash value.

11. The method according to claim 10, wherein the file information is related to an attribute of a file, which represents whether the file has a long file name, whether the file is a deleted file, whether a volume label name is present, whether the file has a write inhibition attribute, or whether a directory name is present.

13. A program causing a computer to execute an image processing method of claim 10.

14. A computer-readable storage medium storing a program of claim 13.

12. An image processing apparatus for storing an image in a recording medium, comprising:

identification information acquisition means for acquiring identification information to identity an image file in storing the image file in the recording medium;

file information acquisition means for acquiring file information of the image file;

calculation means for calculating a hash value on the basis of the identification information and the file information; and

storage control means for controlling to store the image file in the recording medium in association with the hash value.
