ABSTRACT:
A magnetic data processing device sequentially receives magnetic data samples each of which is three-dimensional vector data represented by a linear combination of fundamental vectors and which are outputted from a three-dimensional magnetic sensor. The magnetic data processing device defines a statistical population which includes a plurality of the magnetic data samples sequentially inputted and which signifies a rotation of the three-dimensional magnetic sensor of a predetermined range, and operates when a distribution of the magnetic data samples of the statistical population is flat, for deducing a direction perpendicular to a plane which approximates the flat distribution of the statistical population, as vertical-direction data representing a vertical direction.
