ABSTRACT:
An image processing apparatus includes a CCD image reader for reading image data of an original image, histogram calculators for correcting a density of the image data output from the CCD image reader, a digitizer for designating an arbitrary area of the original image, and selectors for selecting different density correction modes for an area designated by the digitizer and a remaining area. The histogram calculators have photograph and character area designation modes.
