Image processing apparatus, its control method and data management method

An image data management method comprising:

• a storage step of having a first management record memory area which is capable of storing a plurality of first management records, each having a given size used for management of image data, and a second management record memory area which is capable of storing a plurality of second management records, each having a size that is different from the size of the first management record;
• an acquisition step of acquiring a storing area for storing a first management record in the first management record memory and acquiring a storing area for storing a second management record in the second management record memory area;
• and
• a management step of managing the image data using the first management record and the second management record;
• wherein when the storing area for storing the first management record cannot be acquired in the first management record memory area, the acquisition step acquires a storing area in the second management record memory area for storing the first management record as a size which is an integral multiple of the size of the second management record, even if a storage size is bigger than a storage size necessary for storing the first management record, and
• wherein the management step stores the first management record having the given size in the storing area acquired as the size of the integral multiple of the second management record.

A non-transitory computer-readable storage medium storing a computer-executable program for causing a computer to perform an image data management method, the method comprising:

• a storage step of having a first management record memory area which is capable of storing a plurality of first management records, each having a given size used for management of image data, and a second management record memory area which is capable of storing a plurality of second management records, each having a size that is different from the size of the first management record;
• an acquisition step of acquiring a storing area for storing a first management record in the first management record memory and acquiring a storing area for storing a second management record in the second management record memory area;
• and
• a management step of managing the image data using the first management record and the second management record;
• wherein when the storing area for storing the first management record cannot be acquired in the first management record memory area, the acquisition step acquires a storing area in the second management record memory area for storing the first management record as a size which is an integral multiple of the size of the second management record, even if a storage size is bigger than a storage size necessary for storing the first management record, and
• wherein the management step stores the first management record having the given size in the storing area acquired as the size of the integral multiple of the second management record.
