摘要： A physical quantity measuring apparatus of the present invention measures a physical quantity from a signal based on a physical quantity output by a physical quantity signal output apparatus. A correction signal output unit outputs a new correction signal based on a signal on the basis of a physical quantity obtained at a given measurement time, a correction signal obtained before that measurement time, and a filter coefficient. A large/small relationship determining unit determines a large/small relationship between the signal on the basis of the physical quantity and the correction signal obtained before that measurement time. A first filter coefficient output unit outputs a first filter coefficient based on the plural large/small relationships.

摘要： The present invention relates to a magnetic sensor and a magnetic detecting method of the same capable of detecting at least a magnetic field perpendicular to a substrate and a magnetic field parallel to the substrate in a state where the respective magnetic field components are mixed. One embodiment of the magnetic sensor detects a magnetic field of the orthogonal three axes, and includes a magnetic detector including a magnetic field sensitive material configured to detect a magnetic field component in a first direction, a magnetic field direction converters configured to convert a magnetic field component in a second direction and a magnetic field component in a third direction into magnetic field components in the first direction, the second direction being perpendicular to the first direction, the third direction being perpendicular to both of the first and the second directions.
