Abstract: PURPOSE: An image photographing device of a mobile terminal and a method thereof are provided to photograph an image in which autofocus is performed under any circumstances in a preview mode performing continuous autofocus. CONSTITUTION: A control unit (110) directs to perform AutoFocus (AF) about a photographed frame if AF is not performed in the photographed frame when photographing is selected in a preview mode while performing Continuous AutoFocus (CAF). The control unit measures a motion variation of the photographed frame by comparing the photographed frame and a frame in which AF was previously performed. If the motion variation of the photographed frame is above a threshold value, the control unit determines that AF was not performed in the photographed frame.

Abstract: PURPOSE: A method and a device for diagnosing a mechanical shutter in a camera module are provided to confirm whether a mechanical shutter is normally operated, and to photograph a normal image. CONSTITUTION: A method for diagnosing a mechanical shutter in a camera module is as follows. After photographing, a camera sensor provides an electric signal. The electric signal is changed into an image signal. When the brightness value of the changed image signal is more than a critical value, it is determined that a mechanical shutter is abnormally operated. After the abnormal operation of the mechanical shutter is determined, the camera sensor is exposed for a certain time.
