发明名称 Half tone image processing apparatus.
摘要 <p>An image processing apparatus for processing a half tone image comprises: an input device to input an image signal; an image forming circuit to form an image onto a recording medium (14) on the basis of the image signal supplied by the input device; a generator (21) to generate a plurality of image data having different densities; a density detector (23) to detect a density of the image formed on the recording medium by the image forming circuit on the basis of the image data generated from the generator; and a forming circuit to form a plurality of density conversion coefficients to convert the density of the image signal supplied by the input device on the basis of the densities of the plurality of images which are detected by the density detector. &lt;IMAGE&gt;</p>
