Claim Text:
1. An image reading device comprising: a reading region setting section setting a reading region of a document to be read; an image reading section reading the document in the reading region set by the reading region setting section to generate image data; an inclination correction section subjecting the image data generated by the image reading section to inclination correction processing in accordance with inclination of the document; and a determination section defining a target region from a whole region of the image data generated by the image reading section and analyzing a portion of the image data corresponding to the document in the target region, thereby determining an attribute of the image data, wherein the reading region setting section sets the reading region, which is set in a case where the inclination correction processing is executed, larger than the reading region, which is set in a case where the inclination correction processing is not executed, and the determination section defines, as the target region, a region obtained by inwardly narrowing the whole region of the image data by a predefined first region in a case where the inclination correction processing is not executed, and defines, as the target region, a region obtained by inwardly narrowing the whole region of the image data by a second region larger than the first region in a case where the inclination correction processing is executed.
