Abstract
A camera module includes a gyro sensor generating shaking data, a first driver integrated circuit (IC) generating a driving signal to move a first lens barrel in one or more directions perpendicular to an optical axis direction, in response to the shaking data provided by the gyro sensor, and a second driver IC generating a driving signal to move a second lens barrel in one or more directions perpendicular to the optical axis direction, in response to the shaking data provided by the gyro sensor. Each of the first driver IC and the second driver IC operates in a normal mode and a low power mode, and when the first driver IC operates in the low power mode, whether to activate a communication path of the shaking data in the first driver IC is determined in response to a mode of the second driver IC.
