ABSTRACT:
A driving circuit for a photographing module includes a load comprising three coils and four signal input ends; a power source configured to drive the coils and capable of providing an intermediate level between a supply voltage level and a ground level; and a set of electronic switch elements. The driving circuit controls the magnitudes and directions of the electric currents flowing through the coils by switching the set of electronic switch elements, thereby enabling the photographing module to perform auto-focusing and compensate for an angle of inclination.
