Abstract
An indicia reading system and associated methods discriminate between types of media upon which encoded indicia is rendered. Encoded indicia rendered upon a medium are imaged using different sets of image acquisition parameter settings. An attempt to decode the encoded indicia that are imaged is made and the image acquisition parameter settings corresponding to successfully decoding the encoded indicia are identified. A type of the medium upon which the encoded indicia is rendered is determined based on which of the sets of image acquisition parameter settings correspond to the encoded indicia being successfully decoded.
