Abstract: The patent discloses a lens barrel driving system and a backlash correction method thereof. In such system, a zoom photo-interrupter (PI) is used to detect the movement of a zooming barrel and generate a first count value. The movement of a focusing barrel corresponds to the movement of the zooming barrel, so that when the zooming barrel is driven to move from an initial position to a first zooming position or from the first zoom position to a second zoom position, the focusing barrel moves correspondingly and its movement triggers a home PI to generate a second count value. Upon the generation of the second count value, a predetermined value is used to replace the first count value so as to correct the error caused by backlash of lens barrels.

When the difference value is within the allowable error range, the processing module writes the current backlash value into the storage module to replace the backlash compensation value. Therefore, the backlash compensation value of the image capturing device can be corrected automatically to enhance image quality.
