ABSTRACT:
An image-processing device includes an image-reading unit that reads image data from a document optically, an image-recording unit that records the image data read onto recording paper, a first-density-correction unit that corrects first density characteristics that depend on the image-reading unit, a second-density-correction unit that corrects second characteristics to reproduce density of the document, a third-density-correction unit that corrects third density characteristics that depend on the image-recording unit, and a control unit that independently controls each of the first, second and third density-correction units to execute density correction.The image-processing device can record a high-quality image by adjusting the above described density characteristics by controlling each of the first, second and third density-correction units independently.
