Abstract
A method enabling a scanning range of a normal scan to map a predetermined range selected under preview in a scanning device is provided. The present invention is characterized in calculating excess control pulses sent to a stepping motor resulting from accumulated pixels during respective exposure times at different scanning resolutions, and accordingly determining the number of control pulses required to send to the stepping motor for a normal scan for scanning a predetermined range selected under preview, so as to exactly map the scanning range of the normal scan to the predetermined range.
