Image file processing apparatus, image file processing method, and storage medium

An image file processing method comprising:

• a first storage step for storing an image into a first memory;
• a first data creating step for creating at least main image data and sub-image data from the image stored by the first storage step;
• a second storage step for storing the at least main image data and sub-image data created by the first data creating step as one file into a second memory;
• and
• a management region setting step for ensuring management information of the sub-image data stored in the same file as the main image data by the second storage step by a predetermined number and setting the management information in a management region of the main image data, and
• the second storage step stores the file based upon content set by the management region setting step when the file is to be stored in the second memory.

A computer-readable storage medium storing a program for causing a computer provided in an image file processing apparatus to function as:

• first storage means for storing an image into a first memory;
• first data creating means for creating at least main image data and sub-image data from the image stored by the first storage step;
• second storage means for storing the at least main image data and sub-image data created by the first data creating step as one file into a second memory;
• and
• management region setting means for ensuring management information of the sub-image data stored in the same file as the main image data by the second storage means by a predetermined number and setting the management information in a management region of the main image data, and
• first storage control means for performing control so as to store the file based upon content set by the management region setting means when the file is to be stored in the second storage means.
