Abstract
The present invention relates to a controller of a camera module capable of simplifying a measurement system and reducing cost by having a frequency response measurement function. A controller of camera module according to an embodiment, in a driving mode, preprocesses an actuator position value signal sensed by a Hall sensor to output to a measurement equipment, a target position value, arithmetic processes a target position value, an actuator position value signal and a disturbance signal supplied from the measurement equipment to output an error value signal to the measurement equipment, and generates an actuator driving signal that compensates for the error value signal to drive an actuator.
