A method of correcting information scanned by an image scanner includes scanning a first number of positions of a first portion of a correction member having different reflectances to obtain first data. A second number of positions of a second portion of the correction member having different reflectances are scanned to obtain second data. The first data is transformed to obtain transformed first data. The second data is transformed to obtain transformed second data. A table that includes relationships between reflectances and differences of the transformed first data and the transformed second data is generated for a third number of positions greater than each of the first number of positions and the second number of positions.
