A driver, wherein the driver is connected to a controller including a first position control unit configured to generate a first position control signal indicating a first target position to which an object provided with an image sensor or a lens is to be moved, and a first master port configured to output the first position control signal, and the driver comprises:

• a first slave port connected to the first master port;
• a first driving unit configured to provide driving force to the object based on the first position control signal;
• a second position control unit configured to generate a second position control signal indicating a second target position to which the object is to be moved;
• and
• a second master port configured to output the second position control signal to another driver.
