A photographing device includes a geomagnetic sensor which detects an intensity of geomagnetism, an image capture unit which captures an image, and a lens tube including a part that exerts magnetic influence on the geomagnetic sensor, wherein a position of the part is shiftable. In addition, the photographing device includes a detection unit which detects a current shifted position of the part in the lens tube, an obtaining unit which obtains a magnetic field that exerts magnetic influence on the geomagnetic sensor from the lens tube corresponding to the current shifted position detected by the detection unit, and an orientation calculation unit which calculates an orientation by correcting an output of the geomagnetic sensor based on the magnetic field obtained by the obtaining unit.
