Abstract
A first part calculates corrected image data for each pixel in the range in which the reading parts of the adjacent image sensors overlaps in the main scan direction, for correcting the image data for a position shift less than an amount corresponding to one pixel in the main scan direction of the image sensors. A correcting method is determined in such a manner that a position shift amount to be corrected increases in a step-by-step manner as moving from a base portion to an end portion in the range in which the adjacent image sensors overlap in the main scan direction. A second part multiplies the image data corrected by the thus-determined correcting method by a weighting factor determined according to a position in the main scan direction in the adjacent image sensors.
