1. A movement detection device comprising:

  • an acceleration detection unit that detects each respective acceleration component of acting acceleration for each axis of a three-dimensional orthogonal coordinate system and outputs respective acceleration component data;

    a splitting unit that 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; and

    a movement detection unit that 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.
