Abstract
Official abstract text for this publication.
A motion detection device includes: an acceleration detection unit, a separating unit, a gravity axis determination unit, and a motion detection unit. The acceleration detection unit detects acceleration components of each axis of a three-dimensional rectangular coordinate system of acceleration acting on the acceleration detection unit and outputs sets of acceleration component data. The separating unit separates the outputted sets of acceleration component data into stationary components and motion components. The gravity axis determination unit determines an axis whose separated stationary component is the largest to be a gravity axis. The motion detection unit detects, if an axis corresponding to a largest motion component showing a largest value of the separated motion components is an axis other than the determined gravity axis, a motion axis of the acceleration detection unit on the basis of the largest motion component.
