Imaging apparatus and optical axis correction method of imaging apparatus

An imaging apparatus including a plurality of imaging units each having a lens and an image pickup device, at least one of the plurality of imaging units being a wide-angle imaging unit having a lens with a wider angle of view than another imaging unit, and at least one of the plurality of imaging units being a zoom imaging unit having a lens with a narrower angle of view and a higher magnification than the wide-angle imaging unit and mounted rotatably to the imaging apparatus, the imaging apparatus comprising:

• a driving unit that rotates the zoom imaging unit so as to change an imaging range of the zoom imaging unit;
• an image comparison unit that compares a partial image of a wide-angle image captured by the wide-angle imaging unit and a magnified image captured by the zoom imaging unit;
• and
• an optical axis information update unit that updates optical axis information of the zoom imaging unit based on a comparison result of the image comparison unit.
