Abstract: A document image scanner for reading a scanned document multiple times at resolutions different from the scanned resolution without rescanning. A sensor scans the source document to generate a digitized image that is stored in a memory at a first resolution. An input shifter is coupled to the memory for receiving a first number of pixels per line of the digitized image from memory. A vertical scaling element is coupled to the memory for changing a first vertical resolution to a second vertical resolution as the digitized image is transferred to the input shifter from memory. An output shifter is coupled to the input shifter for receiving a second number of pixels per line of the digitized image from the input shifter, wherein the ratio of the second number to the first number is the scaling factor. A horizontal scaling element is coupled to the memory for changing a first horizontal resolution to a second horizontal resolution as the digitized image is transferred to the output shifter from the input shifter.
