Image processing apparatus, method and program binarizing received image data

摘要

An image processing apparatus receives and binarizes image data in accordance with first and second algorithms to output first and second binarized data which are in turn compared and in accordance with a result of the comparison a region to be corrected is determined in the first binarized data. The region to be corrected then has a value of a pixel binarized in accordance with a third algorithm and replaced with the binarized value.
