Anti-shake

Vincent Bockaert, 123di.com

Another approach to image stabilization is to make the CCD move so that it compensates for the camera movement as implemented in the Konica Minolta DiMAGE A2. The sensor is mounted onto a platform which moves in the opposite way as the movement of the camera, which is determined by motion detectors. According to Konica Minolta, this "anti-shake" system gives you an additional 3 stops. For example if you would require a shutterspeed of 1/1000s to shoot a particular scene, you should be able to shoot at only 1/125s (8 times slower) with anti-shake enabled. This is very useful when shooting moving subjects in low light conditions by panning and/or when using long focal lengths.
