Apparatus and method for controlling noise caused by vibration in camera module for mobile device

An apparatus for controlling noise caused by vibration in a camera module for a mobile device, comprising:

• a level converter for receiving a Pulse Width Modulation (PWM) signal and converting the PWM signal into a Direct Current (DC) signal to control a driving of a Voice Coil Motor (VCM) driver;
• at least one switching unit for forming different current paths according to execution/non-execution of imaging of the camera module using a Voice Coil Motor (VCM);
• a constant-current source circuit for supplying a constant electric current to fix an actuator when the VCM driver applies a reverse bias to the VCM;
• and
• a vibration sensor for sensing if vibration is generated outside the camera module and applying a sensed vibration signal to the VCM driver.
