  • Image reading apparatus, image forming apparatus, non-transitory computer readable medium, and method
    Patent number: 9479666
    Abstract: An image reading apparatus includes a reading unit that reads a plurality of colors in a document, a relative movement unit that causes the reading unit and the document to make a relative movement in a first scanning direction, and an output unit that outputs color information at an interval, the color information indicating whether the document read by the reading unit is chromatic, the interval being longer in the first scanning direction than a length in the first scanning direction of a color misregistration, the color misregistration being expected to occur in an image if a speed of the relative movement fluctuates owing to a unique performance characteristic of the relative movement unit, the image being obtained as a result of reading by the reading unit.

  • Correction control device, image reading apparatus, and correction control method
    Patent number: 9264579
    Abstract: There is provided a correction control device. A correcting unit performs edge enhancement correction on image information of each of documents having been read while the corresponding document and a sensor unit having a light receiving element have been moved relatively to each other. A setting unit sets a filter process to be applied by the correcting unit, according to the distance between the sensor unit and each of the documents.
