Abstract

An image data management device, that records image data captured by a digital camera together with information indicating the use period of the image data, searches for image files captured by the digital camera and checks the use period of the image data which has been found. When the use period of the image file has expired, the image data management device deletes the image file.

Claims

1. An image data management device comprising:

a receiver for receiving image data and information indicating a use period of the image data;

a recorder for recording onto a recording medium the image data and the information indicating the use period of the image data received by the receiver;

a manager for monitoring the use period of the image data recorded onto the recording medium; and

a processor for automatically deleting from the recording medium the image data once the manager detects that the image data has expired the use period.

2. An image data management device according to claim 1, wherein said recording medium is a fixed recording medium.

3. An image data management device according to claim 1, wherein said manager monitors the use period of image data captured by a digital camera among image data recorded on said recording medium.

4. An image data management device comprising:

a setter for setting a use period of image data;

a recorder for recording onto a recording medium information indicating the use period set by the setter along with the image data;

a manager for monitoring the use period of the image data recorded onto the recording medium; and

a processor for automatically deleting from the recording medium the image data once the manager detects that the image data has expired the use period.

5. An image data management device according to claim 4, wherein said recording medium is a fixed recording medium.

6. An image data management device according to claim 4, wherein said setter is manually operated.

7. An image data management device according to claim 4, wherein said manager monitors the use period of image data captured by a digital camera among image data recorded on said recording medium.

8. An image recording device comprising:

a setter for setting a use period for image data which have been captured;

a recorder for recording onto a recording medium information indicating the use period set by the setter along with the image data;

a monitor for checking the use period of the image data to detect whether the image data have expired; and

a processor for automatically deleting from the recording medium the image data once said image data are detected by the monitor to have expired based on the use period.

9. An image recording device according to claim 8, wherein said use period is set based on the captured date.

10. An image recording device according to claim 8, wherein an expiration time for image data is automatically set by the setter to a time one year after a capture time of said image data.

11. An image recording device according to claim 8, wherein said use period is manually set.

12. An image data management device according to claim 8, wherein said monitor checks the use period of image data captured by a digital camera among image data recorded on said recording medium.

13. A method for managing image data, comprising the steps of:

recording onto a recording medium image data along with information indicating a use period;

checking the use period of the image data recorded onto the recording medium; and

automatically deleting from the recording medium the image data if, during the step of checking, the image data is detected to have expired the use period.

14. A method of managing image data in accordance with claim 13, wherein, in said step of checking, the use period of image data captured by a digital camera among image data recorded on said recording medium is checked.

15. A program product on a computer-readable medium executable by a computer, said program product comprising:

instructions for recording onto a recording medium image data along with information indicating a use period;

instructions for checking the use period of the image data recorded onto the recording medium; and

instructions for automatically deleting from the recording medium the image data if, during the step of checking, the image data is detected to have expired the use period.

16. A program product in accordance with claim 15, wherein the use period of image data captured by a digital camera among image data recorded on said recording medium is checked.

17. A method of managing image data, comprising the steps of:

searching a data storage area for each image file stored therein; and

performing, for each image file found in said step of searching, the steps of;

checking the contents of the image file for an indication of a certain file format that provides information representative of a use period for said image file;

determining whether said use period has expired; and

automatically deleting said image file if, in said step of determining, it is determined that said use period has expired.

18. A method of managing image data in accordance with claim 17, wherein, in said step of searching, each image file stored on a computer-readable medium is checked for header information indicative of a particular format.

19. A method of managing image data in accordance with claim 18, wherein each image file recorded by a digital camera among image files stored on said computer-readable medium is checked.

20. A method of managing image data in accordance with claim 17, wherein, in said step of determining, said use period is compared to a current date.

21. A method of managing image data in accordance with claim 17, further comprising the step of setting said use period for said image file.

22. A method of managing image data in accordance with claim 21, wherein said use period is automatically set based on a capture date of said image file.

23. A method of managing image data in accordance with claim 22, wherein said use period is one year from said capture date.

24. A method of managing image data in accordance with claim 21, wherein said use period is set by a user.
