  • Patent number: 8189211
    Abstract: An image processing unit includes an image data input unit, a page-description language (PDL) converter, a special document determination unit, and an image treatment command adding unit. The image data input unit inputs image data. The PDL converter converts the input image data to page-description language data, and transmits an end-of-page command when a page-description language conversion for image data is completed. The special document determination unit determines whether the input image data includes a special document. The image treatment command adding unit instructs the PDL converter to wait for a transmission of the end-of-page command until the special document determination unit issues a determination result. When it is determined that the image data includes a special document, the image treatment command adding unit generates an image treatment command for the image data. The image treatment command adding unit transmits the image treatment command with the end-of-page command.

  • Patent number: 7525703
    Abstract: An image reading apparatus includes an abnormal pixel detection device configured to examine a value of standard white image data, which is acquired by reading a white image to be a standard for a shading correction, on a pixel-by-pixel basis, to determine whether or not pixels are abnormal, wherein a previously specified value is stored for use as the standard white image data for pixels which are determined to be abnormal by the abnormal pixel detection device. As a result, costs of the image reading apparatus can be reduced because a special memory device for memorizing the positions of abnormal pixels is not required.

  • Patent number: 7508992
    Abstract: An apparatus for image processing is disclosed. The apparatus is for reducing one or more runlengths by converting binary-format image data for each of black and white runlengths in one direction relative to the data so as to obtain the reduced image data relative to that direction. In the apparatus, when performing an operation of reducing a given one of the runlengths, the operation is performed with reference to one or more runlengths, other than the given runlength, of the same line that have already been reduced.

  • Patent number: 7369283
    Abstract: A color image reading apparatus reads an original image by a line sensor through sequentially lighting respective light sources of a plurality of colors with respect to a scan line. An analog-to-digital converter converts an analog image signal read by said line sensor to digital image data. A lighting frequency ratio setting part sets the lighting frequency ratio for the light sources such that not all of the light sources are equally lighted. A thinning control part performs thinning control of lighting lines according to the lighting frequency ratio at which the light sources are lighted. A read data combining part combines read data of the plurality of colors according to a predetermined combination, said read data being obtained by the thinning control.
