Patent ID: 7995908

Claim:
An image stabilizing camera system comprising: a fixed body, the fixed body having a first receiving cavity therein and an inner surface facing to the first receiving cavity, the inner surface having a first receiving portion therein, the fixed body comprising a bottom plate; a movable unit received in the first receiving cavity, the movable unit having an outer surface facing to the inner surface, the outer surface having a second receiving portion therein; a pivot member located between the fixed body and the movable unit, the pivot member being engagingly received in and between the first receiving portion and the second receiving portion; a motion sensor disposed on the fixed body and configured for detecting a movement of the image stabilizing camera system; and a driving module configured for driving the movable unit to rotate around the pivot member to compensate a movement of the image stabilizing camera system based on a motion detection result of the motion sensor, the driving module comprising a piezoelectric driving unit disposed between the fixed body and the movable unit, and a control circuit, the piezoelectric driving unit comprising a hollow connecting body mounted on the movable unit, a threaded shaft threadedly engaged with the hollow connecting body, and two piezoelectric members mounted on the hollow connecting body, the threaded shaft comprising an end supported by the bottom plate, the two piezoelectric members being spaced from each other, and both spaced from the fixed body, the control circuit being configured for alternately applying voltages to the two piezoelectric members to alternately deform the two piezoelectric members.
