Abstract
The present invention is a system and method that performs a scaling and thresholding operation or a scaling and halftoning operation for each pixel from an image sensor in a single step. The system creates, depending on a mode selected, scaled threshold values or scaled dither matrix values from the scan of a reference document and a predetermined threshold or a predetermined dither matrix. The values are loaded into a single memory. The output of the memory is supplied to a comparator which compares the pixel data from the scanner sensor to the scaled threshold values or the scaled dither matrix values. The serial output of the comparator is converted into parallel data and stored for further processing.
