1. A system of changeable lens self-adaptive control and compensation, comprising:
a lens holder configured to carry a plurality of types of different lenses;
an actuator connected to the lens holder and configured to actuate movement of the lens holder; and
a controller electrically connected to the actuator, the controller being configured to determine, when controlling the actuator to drive the lens holder, whether maximum predetermined output torsion of the actuator is incapable of driving the lens holder when the lens holder is at each of positions, and to build a lookup table corresponding to each of the positions, the controller being configured to record a position to be a broken point in the lookup table in response to the maximum predetermined output torsion being incapable of driving the lens holder when the lens holder is at the position.
