Abstract
An image reader includes a first calculation unit for calculating an output value from an output value of a photodetector adjacent to a specific photodetector in read-width direction; a second calculation unit for calculating a ratio between a first value and a second value, the first value being an output value of the photodetector disposed in conveyance direction of the specific photodetector, and the second value being an output value of the photodetector adjacent, in the read-width direction, to the photodetector disposed in the conveyance direction of the specific photodetector; and a pixel correcting circuit that multiplies the values obtained by the first calculation unit and second calculation unit, substitutes the product for the output value at the pixel position of the photodetector specified by the pixel detecting circuit, and produces as a line output the substitute together with output values at pixel positions of the photodetectors not specified.
