Claim:
1. A mobile terminal, comprising: a first camera module including a first capture unit to capture an object to acquire a first image, a first actuator, and a first case enclosing the first capture unit and the first actuator; a second camera module including a second capture unit, separated from the first capture unit, to capture the object to acquire a second image, a second actuator, and a second case enclosing the second capture unit and the second actuator, wherein the first capture unit includes a first lens unit and a first image sensor, the first image sensor fixedly attached on the first case for converting an optical signal received through the first lens unit into an electrical signal, and the second capture unit includes a second lens unit and a second image sensor, the second image sensor fixedly attached on the second case for converting an optical signal received through the second lens unit into an electrical signal, and wherein the first actuator is configured to control a location of the first lens unit with respect to the first image sensor, and the second actuator is configured to control a location of the second lens unit with respect to the second image sensor; a controller to analyze a perceived 3-dimensional (3D) image formed by using the first image and the second image, and to determine a relative displacement between the first capture unit and the second capture unit based on a result of the analysis; and a drive unit to drive at least one of the first actuator or the second actuator so as to move at least one of the first lens unit or the second lens unit based on the relative displacement such that an axis of the first capture unit becomes parallel to an axis of the second capture unit in spite of a misalignment between the first case and the second case, wherein the axis of the first capture unit is formed via a center of the first lens unit and a center of the first image sensor, and the axis of the second capture unit is formed via a center of the second lens unit and a center of the second image sensor.
