Patent ID: 7924474

Claim:
An apparatus for processing images previously-formed on first and second sides of a document based on a first condition, comprising: an image scanner having a scanning position, the image scanner scanning images on a document at the scanning position as the document and the scanning position move relative to each other; a first storage section configured to store image data scanned by the image scanner; memory configured store computer-executable instructions; and a processing unit configured to execute the computer-executable instructions that, when executed cause the image processing apparatus to provide: an estimate section configured to estimate an amount of data to be scanned based on estimate information; a judgment section configured to judge whether a rotation process to rotate one of a first side image and a second side image scanned by the image scanner can be performed based on the estimated data amount and an available storage capacity of the first storage section; and a change section configured to change a first condition by reducing the amount of data to be scanned by the image scanner from the first side or the second side of the document when the judgment section judges that the rotation process can not be performed, wherein when the judgment section judges that the rotation process can not be performed, the change section automatically reduces a set value of the scanning condition based on a previously determined reduction ratio.
