摘要：
A portable electronic device and an autofocus control method of a camera of the portable electronic device are disclosed. The portable electronic device provides a G-sensor to detect the orientation of the portable electronic device, and provides a storage unit to store autofocus lookup tables for different orientations of the portable electronic device, respectively. According to orientation information from the G-sensor, the central processing unit of the portable electronic device selects one autofocus lookup table from the storage unit and thereby generates an actuating signal for a focus model. The focus model of the portable electronic device is actuated by the actuating signal to adjust an image distance between a lens module and an image sensor of the camera.
