<p>Disclosed is an image processing apparatus for binarizing an image scanned by a shuttle type scanning unit of a multifunctional function using small amount of memory. After scanning pixels of one slice of a document, each of pixels of the scanned slice are binarized using a mask. The error values generated during binarizing final pixels of a plurality of slices of the band are stored in a first memory, and error values generated during binarizing each of the pixels of the scanned slice are stored in a second memory. When each of the first pixels of a plurality of slices in the next band are binarized, the previously stored error values are retrieved and used to binarize the current slice. In addition, by using minimum band memories, the cost price of the multifunctional machine can be reduced. <IMAGE></p> |
