  • OPTICAL DEVICE AND METHOD OF MOVING LENS THEREOF
    Publication number: 20110150455
    Abstract: An optical device includes a lens, a horizontal transmission module, a vertical transmission module, a horizontal driving unit, a vertical driving unit, a horizontal orientation detector, a vertical orientation detector, a user interface, and a control unit. The horizontal driving unit moves the lens horizontally via the horizontal transmission module. The horizontal orientation detector can detect horizontal movement of the lens and emit a horizontal sensing signal. The vertical driving unit can move the lens vertically via the vertical transmission module. The vertical orientation detector can detect vertical movement of the lens and emit a vertical sensing signal. The user interface can generate an operation signal. The control unit can control movement of the lens according to the operation signal, the horizontal sensing signal, and the vertical sensing signal.
