Abstract
An image reading apparatus includes a conversion unit and a setting unit. The conversion unit converts first image information into second image information by using a predetermined color conversion factor group. The setting unit (i) obtains the second image information of a color sample of a plurality of colors converted by the conversion unit from the first image information, the first image information generated by reading the color sample, the color sample used to correct a color level difference according to a light source, (ii) selects a color conversion factor group corresponding to the obtained second image information of the color sample based on the correspondence relationship between a color conversion factor group and a color level of the second image information of the color sample, and (iii) sets the selected color conversion factor group instead of the predetermined color conversion factor group of the conversion unit.
