Abstract: PURPOSE: A method and device for correcting a scanning error in a flatbed scanner is provided to minimize a scanning error by a deviation of a CCD(Charge Coupled Device) module by deciding scanning positions according to each device. CONSTITUTION: A control unit controls a CCD module for being moved to a home position(301). If the CCD module is reached to a home position(302), the CCD module performs a warm-up for a predetermined time(303). The control unit controls the CCD module for being moved to a white shading plate and performs a white shading(304). The control unit reads a black patch provided in the white shading plate through the CCD module, compares an obtained result with a reference value stored in a memory, and decides a scanning area, a scanning position, and a scanning rate with respect to a glass(305). Thus, a scanning error generated by a deviation in accordance with the CCD module is corrected. An actual scanning is performed through the glass based on the scanning area and the scanning position(306).

Abstract: Photoelectric conversion elements of line sensors (CIS22 to CIS26) staggeredly arranged read a white reference plate to acquire a white reference read value A, and a white reference read average value AA is determined from the white reference read value A for each line sensor. Further the photoelectric conversion elements read another white reference plate placed on a document support plate to acquire a white reference read value B, and a white reference read average value BB is determined from the white reference read value B for each of the line sensors (CIS22 to CIS26). Using the white reference read values AA, BB a sensitivity effect coefficient C used for uniforming the sensitivities different because of the variation of the distances from the line sensors (CLS22 to CLS26) to the document support plate is determined by dividing the average value BB by a data processing section for each of the photoelectric conversion element of the line sensors. By using a white reference read value Aa acquired by reading a white reference plate immediately before reading a document and a black reference read value, a white reference read value Aa for shading correction for correcting a document read value E is corrected with the sensitivity offset coefficient C. In such a way, irrespective of the variation of the distances from the line sensors to the document support plate, the variation of the document read values read from the photoelectric conversion element of the line sensors can be suppressed.
