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.
