Abstract:
1. An image reading device comprising: a reading unit that includes a plurality of read pixel-arrays and that converts a signal charge obtained from pixels in each read pixel-array to an electric signal and outputs the electric signal as a read signal of each read pixel-array; a first correcting unit that individually delays the read signals of the respective read pixel-arrays output from the reading unit so as to correct misregistration of the read signals; and a second correcting unit that corrects the misregistration of the read signals of the respective read pixel-arrays corrected by the first correcting unit by performing a two-point interpolation process so that a correction amount for the read signal of one specific read pixel-array among the plurality of read pixel-arrays is not smaller than a correction amount for the read signal or signals of the remaining read pixel-array or pixel-arrays.
