ABSTRACT:
A method and apparatus for synchronizing the line time and color channel exposure timing signals of a CCD line sensor with the polarization control signal of an AC-polarized arc-discharge lamp in a scanning system. The scanning system comprises a scanner illumination system, including an AC-polarized arc-discharge lamp, for illuminating a document to be scanned, and a scanner imaging system for scanning the illuminated document in a line-wise manner. The scanning system of the present invention is designed to minimize brightness fluctuations on the document being scanned, improving the quality of the scanned image.
