摘要： PROBLEM TO BE SOLVED: To provide an image reader properly and promptly obtaining a shading correction level.
SOLUTION: A first reference white plate 77 is read by a CIS (Contact Image Sensor) 73, and a second reference white plate 78 in a non-passing region 81 adjacent to a document passing region 75 is read at the same time. A shading correction level is obtained from the output level of the CIS 73 corresponding to the second reference white plate 78, and the shading correction level is corrected based on the output level of the CIS 73 corresponding to the second reference white plate 78. The output level V2 of the CIS 73 corresponding to the second reference white plate 78 shows the white level of a document in the document passing region 75. When the output level V1 of the CIS 73 corresponding to the first reference white plate 77 is increased to almost equal to the output level V2, and is obtained as a shading correction level, an error caused by displacement between the first reference white plate 77 and the document passage region 75 is reduced.
