摘要： 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.

摘要： In the image processing apparatus, an image data control unit is connected to at least one of an image reading unit, an image memory control unit, an image processing unit, and an image writing unit. The image data control unit receives any one of an image data read by the image reading unit, image data read by the image memory control unit, and image data processed by the image processing unit. The image data control unit transmits the received image data to any of the image memory control unit, the image processing unit, and the image writing unit.
