Abstract
A digital camera includes a slot where a magnetooptical disk is received. A plurality of folders for managing a plurality of image files is formed in the magnetooptical disk. A recording folder pointer points one of folders as a record destination folder of an image file. A reproducing folder pointer points one of folders as a reproducing destination folder of an image file. In a picture-taking mode, when a shutter key is operated, a CCD imager takes a picture of a subject, and a new image file including a compressed image data of the taken subject are stored in the above mentioned record destination folder by a disk controller. A CPU, then changes a point destination of the reproducing folder pointer to a point destination of a recording folder pointer.
Claims7
A digital camera which accesses a recording medium having a plurality of folders to store a plurality of image files to each of which a file number is assigned, comprising:
- an acceptor for accepting a selecting operation to select any one of the plurality of folders formed in said recording medium;
- a first pointer to point a folder selected by the selecting operation as a record destination folder;
- a second pointer to point any one of the plurality of folders formed in said recording medium as a reproducing destination folder;
- a third pointer to point any one of the image files stored in said reproducing destination folder;
- a writer for writing a new image file accommodating photographed image data to the record destination folder when a recording instruction is issued;
- and
- a first changer to change a point destination of said second pointer and a point destination of said third pointer to a point destination of said first pointer and the new image file, respectively, in association with a writing process of said writer, wherein said writer includes a detector to detect a maximum file number from among the file numbers which are assigned to the image files stored in the record destination folder, and an assigner to assign a file number continuous from the maximum file number detected by said detector to the new image file, and said assigner can assign the same file number to different folders.
