Abstract
The image processing device of this invention processes an input document and performs a separation function which separates the text area and the image area from the input document. The image processing device first determines and coarsely separates the text area and the image area, then corrects the image quality. Then, the corrected image is finely separated into text area and image area, and corrected again. Logic calculation may be performed on the corrected images to further correct the image quality.
