Abstract
An image processing device incorporated in a digital image forming apparatus and capable of effecting various kinds of digital image processing, e.g., erasing, italicizing and shadowing, and blanking with a particular area of an image. Considering the fact that frame lines included in a document image can replace marks to be entered by a marker pen, the image processing device extracts areas each being delimited by a frame line as candidates for image processing.
