Abstract
Reference data for correction are obtained by performing main scanning of a reference plane by a photosensor in a defocusing manner through a lens system, to be stored in memories. Image data of the original read by the photosensor through the lens system are corrected through the reference data for correction stored in the memories. Thus, the original can be read in high fidelity.
