Abstract
Methods for establishing or configuring imaging device settings use the luminance and chrominance values of an original document. The document is identified as either a text document or a photograph based at least in part on the luminance values of the document's pixels, and identified as black and white or color document based at least in part on the chrominance values of the document's pixels. The settings of the imaging device may then be based at least in part on whether the document is a text or photograph, or black and white or color.
