Abstract
A camera module includes a gyro sensor to generate shaking data; a first driver integrated circuit (IC) to generate a driving signal to move a first lens barrel in at least one direction perpendicular to an optical axis direction, according to the shaking data; and a second driver IC to generate a driving signal to move a second lens barrel in at least one direction perpendicular to the optical axis direction, according to the shaking data. The first driver IC includes a register unit to store the shaking data transferred from the gyro sensor, and the shaking data stored in the register unit is transferred to the second driver IC.
