Abstract: An image reading apparatus that makes it possible to reduce the influences of dirt on a white reference chart itself, stripes caused by dust, and the like, and thereby generate accurate data for shading correction. An image processor performs shading correction on image data read by a reader unit. The read image data is compared with threshold values set for each pixel, and a pixel which is out of a range of the threshold values is determined as a singular point pixel. Data of a pixel determined as a singular point pixel is interpolated from data around the singular point pixel. Data of a pixel which is not determined as a singular point pixel is adopted as valid shading correction data. An operation controller controls the number of effective sampling lines from start to termination of sampling to be performed.
