PROBLEM TO BE SOLVED: To correct accurately an offset error included in detection values by a geomagnetic sensor and a gyro sensor. SOLUTION: When acquiring a detection value detected by a sensor device 110, this sensor correction device 100, first of all, determines a sensor capable of outputting more accurate detection value out of a geomagnetic sensor 111 and a gyro sensor 112 from a traveling state of a moving body 130 (step S1). Then, a sensor detection value by the other sensor (sensor which is not determined to be the more accurate sensor in the step S1) is corrected by utilizing a detection value of the more accurate sensor (step S2). When correction in the step S2 is finished, the sensor correction device 100 outputs the detection value of the more accurate sensor and the corrected detection value to an azimuth detection device 120 (step S3), and finishes a series of sensor correction processing.
