Abstract
An apparatus for converting an image data with a threshold value into a bi-level data. The apparatus includes a processing circuit for processing image data of pixels neighboring a target pixel to generate membership functions and for obtaining a fuzzy set from the membership functions, and a threshold value generation circuit for generating a threshold value on the basis of the fuzzy set. The threshold value is used to convert the image data of the target pixel.
