Abstract
In a digital copier which allow the quality of an output image to be adjusted in a plurality of levels, a scanner reads a document image and generates corresponding image data. An analog-to-digital converter transforms the image data to a pixel-by-pixel electric signal. The electric signal is written to an image memory. An image processing section reads a particular portion of the image (e.g. one-fifth in the subscanning direction) out of the memory repeatedly, while changing density each time. The results of such processing are sent to a recording section and printed on a single paper as a combined image. As a result, partial images representative of a particular density each are printed on a single paper. This not only promotes easy evaluation but also saves papers.
