    摘要： An image reproduction apparatus having a basic function at low cost, and additional functions as an option. The image reproduction apparatus is configured to detect invalid pixels, remove a black streak, and detect a blank document page. The image reproduction apparatus includes a base engine/image data controller that includes a process controller, a RAM used as a work area, a ROM in which operation commands are stored, a video controller that processes image data and controls the flow of image data, and an I/O controller that monitors and controls I/Os of various devices, such as drivers or sensors, wherein those parts are connected via a CPU bus. The image reproduction apparatus can be extended into the form of a digital multifunction device by connecting a controller board to the base engine/image data controller via a parallel bus.

    摘要： In an image-processing apparatus, a digital image signal is stored in a memory, and a memory access control part entirely manages all accesses to the memory with respect to the digital image signal. An image processing part converts the digital image signal stored in the memory into an output image signal to be supplied to an imaging unit outputting a visible image based on the output image signal so that a pixel density of the output image signal is higher than a pixel density of the digital image signal read from the memory and an amount of the output image signal is less than an amount of the digital image signal stored in the memory. Accordingly, the central controlled memory is shared by a plurality of functions so as to effectively use the memory, and a high-quality image can be produced by carrying out a density conversion so as to match the pixel density.

    摘要： To solve problems associated with undesirable duplication of see-through back image in a double-sided input document, a method of and a system for substantially eliminating the undesirable see-through back images initially scanns a front side image and a back side image from the double-sided document and store the scanned images. The front side image has portions, and some of the portions include an original front image as well as a see-through back image from the back side image. An edge amount for each of the portions is determined in the front side image. The see-through back images are separated from the original front images based upon the edge amount. To further improve the correct removal of the undesired see-through back image, the above processed portions having a certain edge are smoothed. Character portions and dot pattern portions are further separated from background portions in the smoothed data. Finally, the intensity level of the character portions, the dot pattern portions and the background portions are adjusted by a corresponding predetermined conversion function so as to substantially eliminate the see-through back image.
