  • Patent number: 7072058
    Abstract: An image processing apparatus is connected to a plurality of functional units including an image processor which processes images. A process controller provides control over the entire operation. A ROM previously stores information about the content of the image processing. The process controller reads the information stored in the ROM and transfers this information in a host buffer provided with the image processor. The image processor processes the image data based on the information stored in the host buffer.

  • Patent number: 7064863
    Abstract: 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.

  • Publication number: 20060098227
    Abstract: 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.
