Abstract
Modified image data is composed by combining unprocessed original image data and modification information expressing a modification process applied to that original image data, enabling the original image data to be recreated from modified image data without deterioration in picture quality. In addition, recording modification information at each process step enables past modifications to be undone and redone at any time.
