Kodak i100 Series manual No Noise Filter Used, Lone Pixel

Noise Filter  occasionally small dots or specks appear in the background of a scanned image. These specks increase file compression size and usually contain no image information. Using the Noise Filter on documents containing very fine detail (e.g., the dot on an "i" in 4-point type) may cause information to be lost. It is recommended that you do not use Noise Filter when scanning documents with text smaller than 7-point type.

Noise Filter can be used with bi-tonal images only and is front/rear independent. Choose (none), Lone Pixel or Majority Rule.

•Lone Pixel reduces random noise on bi-tonal images by converting a single black pixel surrounded by white to white or by converting a single white pixel surrounded by black to black.

•Majority Rule sets the central pixel value in a matrix according to the majority of white or black pixels in a matrix.
