Abstract: A measurement unit is attached to a measurement target person and measures an acceleration. A body motion calculation unit obtains the magnitude of a body motion of the measurement target person based on the acceleration measured by the measurement unit. An activity state determination unit time-serially obtains an activity state representing whether the measurement target person is in a first state or a second state, based on a posture decided by a posture decision unit and the magnitude of the body motion calculated by the body motion calculation unit. If the activity state after continues for a predetermined time defined in advance, an activity state correction unit determines that the transition of the activity state obtained by the activity state determination unit has been done. A time correction unit returns the transition time of the activity state determined by the activity state correction unit.
