  • Image processing apparatus having plural detachable image processing units for image processing tasks
    Patent number: 8305638
    Abstract: A controller unit controls an image processing apparatus that includes a scanner unit that acquires image data by scanning an original. The controller unit includes a scanning characteristic correcting unit that converts the image data acquired by the scanner unit into normalized image data, an expanded I/F unit to which a controller image processing unit can be detachably attached to perform an image reducing operation on the normalized image data, and a basic image processing unit that, when the controller image processing unit is not attached to the expanded I/F unit, performs a basic image reducing operation on the normalized image data.
    Type: Grant

  • Two-step predetermined text/image identificataion process and system
    Publication number: 20030007192
    Abstract: To avoid illegal duplication of certain documents such as checks, stock certificate and currency notes, predetermined text and or images are identified before a scanned image is duplicated. To identify the predetermined text and images, a first identification process generates a first identification result. Based upon the first identification result, a second identification determines a final identification result. The two-step identification process substantially reduces a rate for generating false results and increases flexibility in the identification criteria.
