Abstract
A movement detection device that includes an acceleration detection unit, a splitting unit and a movement detection unit is provided. The acceleration detection unit detects each respective acceleration component of acting acceleration for each axis of a three-dimensional orthogonal coordinate system and outputs respective acceleration component data. The splitting unit splits the respective acceleration component data output from the acceleration detection unit into a stationary component obtained by low-pass filter processing and a movement component that is the respective acceleration component data from which the respective stationary component has been removed. The movement detection unit detects which axial direction the acceleration detection unit has moved in for each of the axes based on a movement component indicating the maximum value split by the splitting unit.
