Image reading apparatus reading an original while transporting the same
摘要:
An image reading apparatus includes: three line sensors; a mover moving a platen at a rate relative to the three line sensors; an interline corrector synchronizing the three line sensors' outputs to be a pixel having read a single location on an original; NOR and AND devices comparing three data corresponding to a single location on the original to detect a noise pixel; a determiner depending on a color of a pixel neighboring a pixel to be processed selected from pixels arranged in the main scanning direction, to determine first data from which a noise pixel is initially detected; and a determiner invalidating a noise pixel identical in location in the main scanning direction to the pixel to be processed, that is included in a line input prior to a line including the pixel detected from the first data and that is detected from data other than the first data.
