ABSTRACT:
A measured physical quantity calculating part41calculates a measurement result-corrected value obtained by correcting a measurement result of a sensor unit25by the use of corrected values for the sensor unit25. Subsequently, a measurement environment estimating part42estimates a terrestrial magnetism measurement environment on the basis of at least one measurement result-corrected value. The estimation result is displayed on a display unit13by an estimation result display part43. In this way, the terrestrial magnetism measurement environment is first estimated and then the terrestrial magnetism is measured by the use of the sensor unit25. That is, it is possible to measure the terrestrial magnetism by the use of a magnetic sensor mounted on a mobile information device after estimating the terrestrial magnetism measurement environment.
