Image reading apparatus reading an original while transporting the same

An image reading apparatus comprising:

• a plurality of line sensors arranged to be mutually spaced in a sub scanning direction to scan an original in the sub scanning direction;
• a platen arranged between the original and said plurality of line sensors;
• a mover moving said platen at a rate relative to said plurality of line sensors, said rate being different from that of the original relative to said plurality of line sensors;
• an extractor extracting from each of a plurality of data output from said plurality of line sensors a feature pixel having a predetermined feature;
• a detector comparing pixels of said plurality of data corresponding to a single location on the original to detect the feature pixel extracted from first data of said plurality of data, as a noise pixel if said feature pixel is not a feature pixel for said plurality of data other than said first data;
• a second pixel extractor extracting, based on a value of a first pixel present in second data different from said first data and corresponding to the same location on the original as said noise pixel, a second pixel present in said first data for correcting said noise pixel;
• and
• a corrector correcting said noise pixel based on said extracted second pixel.
