To take full advantage of the increasing capability of high-resolution image sensors in cameras such as the K100D, PENTAX engineers developed Shake Reduction. The mechanism moves the 6.1 megapixel charge-coupled device (CCD) image sensor vertically and horizontally at high speed using magnetic force. Two Microelectromechanical System (MEMS) gyroscopes detect camera shake and a dedicated processing unit determines the adjustment required to stabilize the image sensor. With Shake Reduction, photographers can take sharp pictures at a shutter speed that is 2 to 3.5 stops slower, for example 1/15 sec instead of 1/60 sec with a standard lens.
With a better understanding of materials’ response to load and temperature, researchers could potentially use the knowledge to improve design. The research could even help geologists studying plate tectonics.
