  • Patent number: 8004728
    Abstract: An image scanning device has a scanning unit, a first storage unit, a first determination unit, and a control unit. The scanning unit scans an original document to produce image data. The first storage unit stores a specific condition used by the scanning unit for scanning a specific document. The specific document requires a limited scanning condition. The first determination unit determines based on the image data whether the original document is the specific document. The control unit reads the specific condition from the first storage unit and causes the scanning unit to scan the original document with the specific condition if the first determination unit determines that the original document is the specific document.
