ABSTRACT:
Image data is hierarchically coded by a coder, and the coded data is stored in a database. A decoder hierarchically decodes the coded data stored in the database, and image data corresponding to each hierarchy is generated. The decoder generates image data of a plurality of levels of resolutions from a low resolution to high resolution from the coded data stored in the database. The image data of the high resolution is original image data. Editing such as enlargement, reduction, transfer, and rotation, specified by an operator, is executed using the image data of the low resolution obtained from the decoder. The content of the edit processing by the operator is stored in a memory. When the editing operation ends, CPU executes the edit processing on the original image data obtained from the decoder based on the content of the edit processing stored in the memory. The final editing is thus performed on the original image data.
