Abstract
Each object in input image data is separated into an area by an image area separation unit. An area determined to be a character area based on the image area separation processing is smoothened by an MTF correction unit. The resulting data is then binarized by a binarizing unit. The binarized data is split according to types of objects, and characters and line drawings are vectorized and stored in a storage unit. Alternatively, the characters and line drawings are printed out.
