A first acquiring unit acquires initial output values of a physical quantity sensor. A second acquiring unit acquires target output values for the physical quantity sensor. A first calculating unit extracts first characteristic values by calculating a second-order first characteristics formula which indicates corrected output characteristics of the physical quantity sensor, based on the initial output values and target output values of the physical quantity sensor. The second calculating unit extracts second characteristic values by calculating a second-order second characteristics formula for correcting the first characteristic values, based on a predetermined temperature and the first characteristic values. A computing unit computes a corrected output value for the physical quantity sensor based on the first characteristics formula which is corrected by inputting the second characteristic values to the second characteristics formula.
