Abstract:
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 and an image sensor. The controller is receives measured camera motion information from at least one motion sensor. Prior to acquisition of a succession of image frames, the controller determines a first desired start position, for the camera lens and/or the image sensor and, during acquisition of each respective image frame in the succession of image frames, causes the ISA to shift the camera lens and/or the image sensor so as to compensate for the measured camera motion. During a time interval that falls at least partially between a first and a second successive frame, the controller causes the ISA to relocate the camera lens and/or image sensor to a second desired start position for the second successive frame.
