Summary:PROBLEM TO BE SOLVED: To obtain a wide range video of the entire celestial sphere by modifying a conventional imaging unit that obtains a wide range video image of a half celestial sphere. SOLUTION: In the imaging unit where a CCD camera 12 is provided in front of a convex mirror 1 to photograph the front of the convex mirror 1, a wide-angle lens 10 is provided at the rear side of the convex mirror 1 and the wide-angle lens 10 is connected to a CCD camera 11 via an optical rod 13, a focus P of the convex mirror 1 is arranged at the same point as an NP point Q of the wide-angle lens 10, to prevent production of parallax and the rear side of the convex mirror 1 is photographed, so as to obtain a wide range video image covering nearly the entire celestial sphere.
