Claim Text:
1. A geomagnetism sensing device mounted in an apparatus, the geomagnetism sensing device comprising: a magnetism sensing section including an X-axis sensor, a Y-axis sensor, and a Z-axis sensor aligned in directions of an X axis, a Y axis, and a Z axis, respectively, the magnetism sensing section being capable of freely turning in three-dimensional directions while maintaining an orthogonal relationship among the X-axis sensor, the Y-axis sensor, and the Z-axis sensor, the magnetism sensing section providing detection outputs corresponding X, Y, Z components of a geomagnetic vector detected by the X, Y, and Z-axis sensors; and an operation section configured to: whereby the operation section determines at least one of a position, a state of motion, an angular velocity, a rotational angle, and an angular acceleration of the apparatus with an improved accuracy from the rotational movement of the magnetism sensing section around the rotational axis, and wherein the apparatus is portable equipment configured to perform a specific function associated with a rotational or positional state thereof, the specific function including correcting hand shakes of the portable equipment in which the geomagnetism sensing device is mounted in accordance with the determined rotational or positional state of the portable equipment.
