Abstract

The ratio between first reference data which is acquired by scanning the surface of a white member in a state where the size of a gap is substantially equal to that when a document is scanned and second reference data which is acquired by scanning the surface of the white member in a state where the size of the gap is smaller than that when the document is scanned is calculated as a reference data ratio, and the reference data ratio is stored. In generating shading data for correcting image data of each document, the reference data ratio being stored is multiplied by third reference data which is acquired by scanning the surface of the white member in a state where the size of the gap is substantially equal to that when the document is scanned, thereby generating shading data.
