Abstract:
    A magnetic sensor control device has an input unit, a selection unit, a calculation unit, and a setting unit. The input unit inputs a plurality of magnetic data each having 3 components sequentially output from a 3-dimensional (3D)-magnetic sensor. The selection unit selects 4 magnetic data satisfying a predetermined 4-point selection condition from the plurality of the input magnetic data. The calculation unit calculates a center point equally distant from 4 points corresponding to the 4 selected magnetic data. The setting unit sets 3 components representing the center point as an offset of the magnetic data.
