Abstract: An exemplary image stabilizer includes a stationary supporting frame, a moveable frame, a driving assembly and a resilient assembly. The moveable frame is moveably received in the stationary supporting frame and spaced from the stationary supporting frame. The driving assembly includes a first magnetic member and a second magnetic member. The first magnetic member is positioned on the stationary supporting frame. The second magnetic member is positioned on the moveable frame. The driving assembly is configured for driving the moveable frame to rotate relative to the stationary supporting frame through interaction between the first magnetic member and the second magnetic member. The resilient assembly interconnects the stationary supporting frame and the moveable frame and is configured for counter-rotating the moveable frame relative to the stationary supporting frame.

Abstract: An exemplary image stabilizing camera system includes a fixed body having a first receiving cavity therein, a movable unit received in the first receiving cavity, a pivot member located between the fixed body and the movable unit, a motion sensor, and a driving module. The pivot member is engagingly received in and between the fixed body and the movable unit. The motion sensor is disposed on the fixed body and configured for detecting a movement of the image stabilizing camera system. The driving module is configured for driving the movable unit to rotate around the pivot member to compensate a movement of the image stabilizing camera system based on the motion detection result of the motion sensor.

Abstract: An imaging sub-system, a liquid crystal (LC) element, and a digital focus processor are provided. The LC element is placed in the light path of the imaging sub-system, functioning as the aperture of the imaging sub-system, and includes a periodically patterned electrode which is patterned according to a periodical modulation function and configured to blur an intermediate image captured by the imaging sub-system by applying a controllable voltage thereto. The digital focus processor is configured to deconvolute the periodical modulation function to remove the blur away from the intermediate image and determine an all-in-focus real image.
