Abstract:
     An image scanner for scanning file image based on a step position control table and a method for generating the step position control table are disclosed. Said scannner is composed of scan module for scanning file and generating a group of associated image signals, driver for driving the scan module or file to scan, and controller for controlling scan module and driver. Said controller has a step position control table for storing the number of steps the scan module or file moves under the action of driver. When scanning file, the driver can be precisely controlled by the controller based on the number of steps corresponding to the position of each scan line in the table, so they can be moved to predefined scan line position for scanning, avoiding mechanical error.
