An image processing apparatus includes a converter for reading out a manuscript image signal and converting the read-out signal to an electric signal. A signal processor executes signal processing for the electric signal, and an image generator generates an image in accordance with the processed signal. An outputting unit separates a character area and a photograph area of the manuscript from the read-out signal and outputs an area signal. A changing-over circuit changes over a filtering process in accordance with the area signal. A halftone processor executes in parallel a halftone process for the character area image and a halftone process for the photograph area image, and the changing-over circuit selectively changes over the halftone processing result for the character and the halftone processing result in accordance with the area signal.
