Abstract
An imaging system includes n or more photographing optical system having an imaging optical system having a full angle of view A (degree) larger than 360/n where n is a natural number of 2 or more and a two-dimensional imaging element configured to convert light condensed by the imaging optical system into an image signal, wherein in the imaging optical system of each of the imaging optical systems, a magnification per unit angle of view monotonically increases from 0 to 360/n-degree angle of view, and an increase rate of the magnification monotonically decreases to the full angle of view A (degree) after the 360/n-degree angle of view.
