Claim 6:
7. A reading device comprising:
a reading sensor configured to read a document;
a first transport path including a curved portion;
a second transport path not including the curved portion; and
a controller configured to acquire image data including a document region and a background region from the reading sensor, wherein
the controller
acquires document information about a document, and
sets, based on the document information, a background range indicating a range of a luminance value regarded as the background region, wherein
the document information includes path information indicating a path through which a document is transported,
the controller
sets a first background range when the path information indicates that a document is transported through the first transport path, and
sets a second background range when the path information indicates that a document is transported through the second transport path, and
a minimum value of the second background range is smaller than a minimum value of the first background range.
