Abstract
A camera device including first and second cameras, focal position information of the first camera and focal position information of the second camera are matched with each other. Also, the accuracy of the current focal position of the first camera is determined based on the phase difference of images obtained by the first camera when the first camera is auto-focused. Subsequently, when the accuracy of the current focal position of the first camera is low, an accurate focal position of the first camera is tracked by using the matched focal position information of the second camera. When an auto-focusing function of the first camera is activated, focal position movements are tracked by using the focal position information of the second camera as well as zoom tracking of the first camera, and thus, the accuracy can be improved.
