<p>PROBLEM TO BE SOLVED: To provide an image reading apparatus in which read image non-uniformity caused by influences of light-receiving sensitivity in a light-receiving sensor is reduced.SOLUTION: When reading an image by irradiating a read target with light in a plurality of colors, first line data are stored (S101) which are read by irradiating a reference member with light in one predetermined color among the plurality of colors and on the basis of first reference image data, a generation position of sensitivity non-uniformity in a main scanning direction in reading using the light in the one color is identified (S104 and S105). In document image data read by irradiating a document with light in the plurality of colors, data of the identified sensitivity non-uniformity generation position are corrected (S108 and S109) by using the first reference image data.</p> |
