摘要
In an image processing apparatus for processing inputted binary image data including a first area in which data are binarized by a pseudo half- tone binarizing method and a second area in which data are binarized using a predetermined threshold value by a non-half-tone binarizing method, there is calculated a number of adjacencies representing an adjacency state of the same kind of pixels located within a block area composed of a plurality of pixels including a specified pixel to be processed. Further, there is judged whether each pixel of the inputted binary image data is included in the first area or the second area, based on the calculated number of adjacencies.
