ELECTRONIC APPARATUS AND PROGRAM

摘要

An electronic apparatus includes: a sensor unit configured to detect displacement information of a body including at least acceleration data; a still determination unit configured to determine whether or not the body is in a still state based on a change in a standard deviation with respect to the displacement information for a predetermined number of detections detected by the sensor unit; a gravity calculation unit configured to determine a start of a motion of the body based on a determination result determined by the still determination unit and calculate a gravity component based on first acceleration data that is acceleration data in the start of the motion of acceleration data detected by the sensor unit; a correction unit configured to correct second acceleration data that is acceleration data detected by the sensor unit while the body is moving, based on the gravity component calculated by the gravity calculation unit; and a motion determination unit configured to determine the motion based on the second acceleration data corrected by the correction unit.
