摘要： When an external magnetic field is applied to a sensor unit 12 for various causes, a characteristics curve does not pass through an intersection point of resistance (voltage) and a magnetic field and is offset. That is, an offset voltage (Roff) occurs. In the present invention, in order to determine a correction value for canceling the offset voltage, a difference between output voltages is determined from two stages in which a bias magnetic field is inverted, and the bias magnetic field is controlled until the difference becomes approximately zero. Then, the corresponding bias magnetic field (the electrical current value) when the difference between the output voltages becomes approximately zero is set as a correction value (correction bias). As a result, since correction can be performed even if an offset voltage is applied, it is possible to accurately perform magnetic detection.

摘要： A mobile device or the like having a 3-axis electronic compass is rotated, and the outputs from magnetic sensors disposed in the three axis directions are input to a first arithmetic processing unit (11) so as to obtain the magnetic data X, Y, and Z. By inputting the magnetic data X, Y, and Z to a second arithmetic processing unit (12), gains Gx and Gz can be obtained. A control unit (16) generates access codes x0 and z0 corresponding to the gains Gx and Gz. The correspondence between the access codes x0 and z0 and inclination angle (pitch angle) α or between the gains Gx and Gz and inclination angle (pitch angle) α is tabulated and stored in a memory unit (17). The control unit (16) accesses the memory unit (17) so as to obtain an inclination angle (pitch angle) α0 corresponding to the access codes x0 and z0.

摘要： A voltage generating section applies first and second voltages having inverted polarities to a sensor section. The sensor section outputs a voltage value corresponding to a change in geomagnetism. A bias magnetic field generating section applies an alternating current bias magnetic field to the sensor section. A detecting section detects voltages with respect to the first and second voltages when the alternating current bias magnetic field is applied in positive and negative directions. By taking the difference between the detected voltages, an offset voltage to be outputted from a magnetism detecting circuit is eliminated.
