Abstract
A measured physical quantity calculating partcalculates a measurement result-corrected value obtained by correcting a measurement result of a sensor unitby the use of corrected values for the sensor unit. Subsequently, a measurement environment estimating partestimates a terrestrial magnetism measurement environment on the basis of at least one measurement result-corrected value. The estimation result is displayed on a display unitby an estimation result display part. In this way, the terrestrial magnetism measurement environment is first estimated and then the terrestrial magnetism is measured by the use of the sensor unit. 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.
