Abstract: In a sheet-fed scanner capable of scanning multiple scan lines as a calibration standard for an image signal, a scanning module scans a document, which is fed across a scan region by a sheet-feeding mechanism, and a stationary calibration sheet in the scan region. The scanning module includes an image sensor, a lens and at least one reflecting mirror. An actuator actuates the reflecting mirror to enable the image sensor to sense a plurality of scan lines on the calibration sheet through the lens and the reflecting mirror in order to obtain a calibration standard for the image signal of the document. The calibration standard is adopted to calibrate an image signal of the document, and with this invention, it is possible to avert any flaws in image quality caused by the contaminated calibration sheet.

Abstract: Photoelectric conversion elements of line sensors (CIS22 to CIS26) arranged in a zigzag manner 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). By using the white reference read average values AA and BB, a sensitivity effect coefficient C used for uniforming the sensitivities different because of the variation of the distances from the line sensors (CIS22 to CIS26) 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 this 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.

Abstract: A first set-value calculating unit calculates a first set value of a black-level feedback based on a reflection amount that increases a speed of tracking to a black-level target value in a black-level feedback control. A second set-value calculating unit calculates a second set value of a black-level feedback based on a reflection amount that slows down a tracking to a black-level target value as compared to the speed of tracking of the first set-value calculating unit. A selecting unit selects and outputs any one of the first set value and the second set value and outputs selected value as a set value. A controlling unit controls selection of any one of the first set value and the second set value by the selecting unit based on the black differential value and a gain of the image data.
