An optical image stabilization (OIS) of a camera system includes a controller, a lens and an image stabilizing arrangement (ISA), including one or both of an actuator mechanically coupled with the lens. The controller is configured to: (1) receive measured accelerometer data relating to camera orientation with respect to a gravitational field and causes the actuator to locate the lens at a gravity-adjusted neutral position; and/or (2) synchronously relocate, during a time interval that falls at least partially between a first successive frame and a second successive frame, one or both of the camera lens and an image sensor by controlling a slew motion of the camera lens or image sensor, monitor and controls one or more of exposure time, effective readout time, lens relocation time and frame period, and rebalance the auto exposure algorithm such that the exposure time is less than a critical value.
