1. A control method of a driving mechanism is provided, comprising:
providing a first electrical signal from a control assembly to a driving assembly to move a movable portion to an initial position relative to a fixed portion using the driving assembly, wherein the control assembly comprises a control unit and a position sensing unit, and providing the first electrical signal comprises:
measuring a first limit value of the movable portion on a first dimension; and
measuring a second limit value of the movable portion on a second dimension, wherein the first dimension is different than the second dimension, wherein measuring the first limit value of the movable portion on the first dimension and measuring the second limit value of the movable portion on the second dimension are not performed simultaneously;
reading a status signal from an inertia sensing unit;
using the inertia sensing unit to provide the status signal to the control unit, and then use the control unit to calculate a target position;
using the control unit to provide a second electrical signal to the driving assembly according to the target position for driving the driving assembly;
providing a position signal from the position sensing unit to the control unit; and
using the control unit to provide a third electric signal to the driving assembly according to the position signal to drive the driving assembly.
