Abstract
A picture data processing device in which a region specifying original having markings which physically define a region of interest of an original document to be processed is read and stored. When the original document is read, the stored markings are reproduced to mask out the areas of the original document other than the region of interest. A signal processing operation, such as extraction, rearrangement, or size alteration with respect to the selected region can then be performed.
