发明名称 Image reading apparatus and image reading method
摘要 This invention solves the problem of color misalignment upon reading a color image. An image reading apparatus according to this invention reads an image by scanning a scanning unit which mounts a reading sensor which reads light beams which are emitted by three light sources, which emit light beams of three primary colors, and reflected by an original document. The image reading apparatus conveys the original document by ⅓ of the reading width of the reading sensor in the conveyance direction of the original document every time the image is read. The image is read by switching between the three light sources so that each pixel of the image is read with the light beams from them.
