Abstract
An apparatus for converting image signals into binary signals is disclosed. The apparatus comprises: a binarizing section for binarizing image signals; a connectivity distribution section for obtaining connectivities between pixels from binary signals and for producing a connectivity distribution; and a judging section for, from connectivity distributions obtained with different binary levels, judging the level at which the frequencies of maximum and minimum connectivities are highest and the sum of the frequencies of intermediate connectivities is minimal.
