PHYSICAL VOLUME DATA CORRECTION DEVICE AND PHYSICAL VOLUME DATA CORRECTION METHOD

There is provided a physical quantity data correcting device that can accurately and rapidly make a correction of physical quantity data even under an influence of a variation in an external environment or a disturbance by causing a computation control unit to appropriately control an approximate ellipsoid computing unit and/or a correction coefficient computing unit on the basis of a control parameter group. A physical quantity data acquiring unit (11) acquires physical quantity data output from a physical quantity detecting unit that detects physical quantities. A data selecting unit (11a) selects the acquired physical quantity data. An approximate ellipsoid computing unit (12) computes an approximate expression of an n-dimensional ellipsoid indicating a distribution shape obtained by distributing the selected physical quantity data in an n-axis (where n is an integer of two or greater) coordinate space. A correction coefficient computing unit (13) computes correction coefficients for correcting the computed n-dimensional ellipsoid to an n-dimensional sphere. A computation control unit (14) controls the approximate ellipsoid computing unit (12) and/or the correction coefficient computing unit (13) on the basis of a control parameter group (26). A correction data output unit (15) corrects the physical quantity data.
