ABSTRACT:
The invention relates to an apparatus and method for image processing, which can prevent saturation of a high-density image to read the image in which gradation skip is not generated in reading information on a document. Image density is detected based on an image signal, and sensitivity characteristics of the image signal is switched based on the detected result.
