<P>PROBLEM TO BE SOLVED: To accurately obtain coordinates of a center of a circular area in an omni-azimuth image. Ž<P>SOLUTION: An omni-azimuth photographing system 1 is constituted of the omni-azimuth photographing auxiliary device 2 and a digital camera 3. The omni-azimuth photographing auxiliary device 2 includes an omni-azimuth mirror 5, a sheet member 6 and a cylindrical member 7. The omni-azimuth mirror 5 is formed in semicircular shape whose cross section has the shape of a sphere, a parabola or a hyperbola or the like, and attached to an almost center position of the sheet member 6. A surface of a portion of the sheet member 6 other than a portion where the omni-azimuth mirror 5 is attached is colored in monochrome. The cylindrical member 7 is made of transparent material such as resin and glass, and the omni-azimuth mirror 5 is attached to one end of the cylindrical member 7 and the digital camera 3 is attached to the other end thereof.
