    Abstract: During a sheet-through operation, for a first original, a shading operation is performed to acquire white data and a light-quantity measuring operation is performed to acquire a reference value. For subsequent originals, only the light-quantity measuring operation is performed to acquire a subsequent light quantity. If the reference value and the subsequent light quantity differ greatly, the shading operation is performed at this time point to acquire new white data. The sheet-through operation is not stopped when the shading operation is not performed and the sheet-through operation is stopped when the shading operation is performed.

    Abstract: A movable calibration device for a sheet-fed scanner includes a calibration sheet and a cam. A scanning module scans an image on the calibration sheet for calibrating the sheet-fed scanner. The cam, driven by a motor, moves the calibration sheet into and out of a scan window of the scanning module. The calibration sheet can be moved out of the scan window without reversing the rotational direction of the motor. The entire calibration sheet is moved in a linear path.

    Abstract: An apparatus and method for correcting a scanning error in a flatbed scanner, can minimize the scanning error due to deviations in position or scanning of a CCD (charge-coupled device) module by determining a scanning position, a scan region, and a scan rate for each flatbed scanner. The scanning error correcting apparatus includes a white shading plate having a black patch, a reading module for reading the white shading plate and the black patch, and a controller that compares information about the black patch read by the reading module with a predetermined reference value to correct the scanning error in the flatbed scanner. Thus, the apparatus and method can secure a scanning region in horizontal and vertical directions as wide as possible for each flatbed scanner and prevent occurrences of errors in a scanned image due to deviations of the CCD module. Furthermore, the apparatus and method provide an accurately scanned image having a desired scan rate by comparing right and left sizes and the entire scan size for a currently scanned region.
