LENS DRIVING SYSTEM AND METHOD |
| 摘要 |
A lens driving system is configured for driving a lens to a focus position, and includes a control unit and a driving unit electrically connected to the control unit and coupled with the lens. The control unit acquires the focus position, calculates a main current value according to the focus position, and calculates a number of secondary current values according to the main current value. The secondary current values gradually increase to the main current value. The driving unit drives the lens to the focus position according to the secondary current values. |
