PROBLEM TO BE SOLVED: To provide a semiconductor device, electronic equipment, and a determination method, capable of reducing power consumption of the electronic equipment having a plurality of sensors.SOLUTION: Electronic equipment 10 analyzes an acceleration value acquired by a sensor control microcomputer 12 from an acceleration sensor 14 to determine which of repose, walking or a bicycle, and a vehicle or a train a movement state of a user carrying the electronic equipment 10 is. In a case where the movement state is walking or a bicycle, an atmospheric pressure sensor 16 is turned on for a constant time period to acquire an atmospheric pressure value, and consumption calorie calculation processing is performed on the basis of the acquired atmospheric pressure value. In a case where the movement state is a vehicle or a train, a geomagnetic sensor 18 is turned on for a constant time period to acquire geomagnetic value, and vehicle/train determination processing is performed on the basis of the acquired geomagnetic value.
