Abstract
A system and a method of changeable lens self-adaptive control and compensation are provided. The system includes a lens holder, an actuator, and a controller. The lens holder carries a plurality of types of lenses. The actuator is connected to the lens holder, and drives the lens holder to move. The controller is electrically connected to the actuator, and is configured to determine whether maximum predetermined output torsion of the actuator is incapable of driving the lens holder when the lens holder is at each of positions when controlling the actuator to drive the lens holder, and to build a lookup table corresponding to each of the positions. The controller is 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 drive the lens holder when the lens holder is at the position.
