Unwanted black speckles or splotches in a scanned document are referred to as noise. Noise Reduction improves image clarity by removing black spots, dust, or voids in white areas. Choose a noise reduction level in the Noise Reduction
The more noise in a scanned image, the larger the compressed file size. Also, if images are being produced for an OCR system (a system that can read text from an image produced by a scanner), too much noise may lessen the reliability and read rate of the OCR system.
While choosing the larger matrix decreases large noise, commas (,) or decimal points (.) may disappear as well. Noise Reduction is valid only in Binary mode. Using Noise Reduction is not recommended when using a Dither setting.
