Application ID: 11947316

Base Claim:
1. An image scanning device comprising: a scanning unit that scans an original document with a scanning condition to produce image data; a first storage unit that stores a specific condition used by the scanning unit for scanning a specific document, the specific condition including a limited requirement required by the specific document, and a limited scanning condition conforming to the limited requirement; a first determination unit that determines whether the scanning condition satisfies the limited requirement for the specific document; a control unit that causes the scanning unit to scan the original document with the scanning condition, if the first determination unit determines that the scanning condition satisfies the limited requirement for the specific document, the control unit causing the scanning unit to scan the original document with an initial condition to produce initial image data if the first determination unit determines that the scanning condition does not satisfy the limited requirement for the specific document; and a second determination unit that determines based on the initial image data whether the original document is the specific document, wherein the control unit causes the scanning unit to scan the original document with the scanning condition, if the second determination unit determines that the original document is not the specific document, and the control unit reads the specific condition from the first storage unit and causes the scanning unit to scan the original document with the limited scanning condition if the second determination unit determines that the original document is the specific document.

Claim 11:
11. The image scanning device according to claim 1 , further comprising: an identification unit that identifies at least one of a character, a symbol, and a graphic included in the initial image data; and a second storage unit that stores a character, a symbol, and a graphic included in the specific document, wherein the second determination unit determines that the original document is the specific document, if one of the character, the symbol, and the graphic stored in the second storage unit corresponds to the at least one of the character, the symbol, and the graphic identified by the identification unit.
