ABSTRACT:
An actual recordable area in which no image data has been recorded is detected from a recording medium. The actual recordable area is divided by a file size of image data which are compressed with a maximum compression ratio, so that a number of actual recordable files is obtained. A potential recordable area is calculated under conditions under which the image data are to be compressed with a maximum compression ratio, and is divided by the file size so that a number of potential recordable files is obtained. The number of the actual recordable files and the number of the potential recordable files are added to each other, and thus, a number of expanded recordable files is obtained.
