<p>The apparatus and method of the present invention utilizes three scaling functions for bi-tonal digitized image data such as documents. The digitized document resolution (i.e. from a digitizing scanner) may be different from the resolution of an image output device (i.e. laser printer, CRT display, fax machine, etc.). The invention takes in the scanned image data and scales the data to compensate for the resolution mismatch of the output device. Although the invention is intended for document archive applications (such as scanning documents on microfilm), the scaling can be performed on any bi-tonal image.</p> |
