Abstract
A camera module which includes an image sensor, a three-dimensional (3D) sensor, a pre-processor, and an actuator controller. The pre-processor may be suitable for receiving image information from the image sensor, generating an auto focusing control signal based on the image information, and providing an auto focusing control signal to the actuator controller. The actuator controller may be suitable for receiving the auto focusing control signal, generating an actuator driving signal based on the auto focusing control signal, and providing the actuator driving signal to the 3D sensor. The 3D sensor may be suitable for adjusting a field of view (FOV) based on the actuator driving signal.
