Abstract:
An image reading device comprising:a light source that radiates a plurality of light beams of differing color components;an optical system that changes said plurality of light beams to a plurality of parallel beams, and leads said plurality of parallel beams to a recording medium, one of said plurality of parallel beams being parallel to an optical axis of said optical system, a remaining beam of said plurality of parallel beams being inclined to said optical axis;a line sensor that senses said plurality of parallel beams passing through said recording medium, to generate at least first and second line image signals corresponding to an image recorded on said recording medium, said one of said plurality of parallel beams, which passes through a predetermined point on said recording medium, entering a first portion of a light receiving surface of said line sensor, said remaining beam of said plurality of parallel beams, which passes through said predetermined point, entering a second portion of said light receiving surface;an out-of-register sensing processor that senses an amount of out-of-register, being a distance between said first and second portions; andan out-of-register adjusting processor that adjusts at least one of said first and second line image signals in such a manner that an effect of said amount of out-of-register on a color image reproduced from said first and second line image signals is reduced.
