A method and apparatus for performing motion estimation in a digital video system is disclosed. Specifically, the present invention discloses a system that quickly calculates estimated motion vectors in a very efficient manner. In one embodiment, a first multiplicand is determined by multiplying a first display time difference between a first video picture and a second video picture by a power of two scale value. This step scales up a numerator for a ratio. Next, the system determines a scaled ratio by dividing that scaled numerator by a second first display time difference between said second video picture and a third video picture. The scaled ratio is then stored calculating motion vector estimations. By storing the scaled ratio, all the estimated motion vectors can be calculated quickly with good precision since the scaled ratio saves significant bits and reducing the scale is performed by simple shifts.

A freely rotatable micromechanical plate is achieved by employing at least three rotatable plates that are each suspended from a substrate via respective springs, and are coupled via other respective springs to at least three moveable plate attachment points, so that rotation of the rotatable plates about an axis transfers motion to the moveable plate attachment points. Respective posts couple the movement of each respective moveable plate attachment point to a moveable plate. In operation, the rotatable plates may be individually rotated, and the resulting motion of each rotatable plate is passed to its respective moveable plate attachment point. The combined motion of the moveable plate attachment points is passed to the moveable plate via the posts. Using proper control, the plate may be made to tip, tilt and piston. Advantageously, the piston motion may achieve a high vertical movement frequency response.
