Abstract
An image capturing apparatus using a limited-rewriteable storage medium is disclosed. The image capturing apparatus writes generated image data in the limited-rewriteable storage medium at the time of shooting processing. On the other hand, an internal memory in the image capturing apparatus holds management information such as a FAT and directory entry. The apparatus writes the management information in the limited-rewriteable storage medium after the contents of the information are determined.
Claims5
An image capturing apparatus, comprising:
- a holder unit which allows a storage medium to be attached/detached;
- a discrimination unit adapted to determine whether a storage medium attached to said holder unit is a limited-rewriteable storage medium;
- a built-in storage unit which is rewriteable;
- and
- a write control unit adapted to:
- (a) when said discrimination unit determines that the storage medium is a limited-rewriteable storage medium, perform control to write image data generated by shooting processing in the storage medium, while temporarily saving management information for the image data in said built-in storage unit and writing the management information in the storage medium every time the management information reaches a predetermined data size;
- and (b) when said discrimination unit determines that the storage medium is not a limited-rewriteable storage medium, perform control to write both image data generated by shooting processing in a shooting mode and the management information in the storage medium before the management information reaches the predetermined data size.

A method comprising:
- determining whether a storage medium attached to a holder unit, which holder unit allows a storage medium to be attached/detached, is a limited-rewriteable storage medium;
- when it is determined that the storage medium is a limited-rewriteable storage medium, performing control to write image data generated by shooting processing in the storage medium, while temporarily saving management information for the image data in a built-in storage unit that is rewriteable and writing the management information in the storage medium every time the management information reaches a predetermined data size;
- and
- when it is determined that the storage medium is not a limited-rewriteable storage medium, perform control to write both image data generated by shooting processing in a shooting mode and the management information in the storage medium before the management information reaches the predetermined data size.
