<P>PROBLEM TO BE SOLVED: To provide a photographing device equipped with a geomagnetic sensor which, even when a component having varying quantity of magnetic influence on the geomagnetic sensor due to displacement is included, eliminates the influence and accurately measures azimuth. <P>SOLUTION: The photographing device comprises: a geomagnetic sensor for detecting geomagnetism; an imaging part for taking an image; a movable part including a part which has magnetic influence on the geomagnetic sensor and whose position is variable; storage means storing displacement magnitude versus magnetic field data indicating the relation between the displacement magnitude of the movable part and the magnetic field imparted from the movable part on the geomagnetic sensor; and azimuth calculation means which, based on the displacement magnitude versus magnetic field data and the displacement magnitude of the movable part, determines the magnetic field imparted from the movable part on the geomagnetic sensor (S8-S10), and which calculates the azimuth (S11) with deduction of the magnetic field from the output of the geomagnetic sensor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
