A method for positioning a focus lens assembly, the focus lens assembly being movable along an optical axis relative to an image sensor, the method comprising:
- moving the focus lens assembly against a mechanical stop;
- and
- moving the focus lens assembly from the mechanical stop to a frame focus position for exposure of a frame.
A mobile apparatus comprising:
- an image sensor,
- a focus lens assembly movable along an optical axis relative to the image sensor,
- a mechanical stop,
- an actuator coupled to the focus lens assembly to position it,
- a focus control unit configured to provide focus lens assembly positioning instructions,
- a driver coupled to the focus control unit and to the actuator, and configured to receive the focus lens assembly positioning instructions and to supply an actuating input to the actuator to position the lens focus lens assembly according to the focus lens assembly positioning instructions,
- wherein the focus lens assembly positioning instructions comprise instructions to move the focus lens assembly against the mechanical stop, and from the mechanical stop to a frame focus position for exposure of a frame.
