    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: An image forming apparatus for performing at least a copying function includes an engine board, an image reading unit, an image forming unit, a controller board detachably connected to the engine board to add at least one application function to the copying function of the image forming apparatus, an operation unit, and a parallel bus that connects the controller board to the engine board. When the controller board is connected to the engine board, the operation unit displays information of the copying function and the at least one application function, and when the controller board is detached from the engine board, the operation unit displays the information of the copying function. Each of display layouts of the operation unit for the copying function is substantially identical between when the controller board is connected to the engine board and when the controller board is detached from the engine board.

    摘要: 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.
