Abstract
Provided is a method and system for detecting rotational movement of a camera. Three pairs of accelerometers are located in the camera, with the motion sensing axes of each of the accelerometers in each of the pairs parallel to one another. The accelerometers are relatively positioned in the camera such that the planes formed by the motion sensing axes of each of the pairs of accelerometers are substantially mutually orthogonal.
