Wide-angle optical imaging system including two objectives

摘要

An imaging system includes n photographing optical systems, each including an imaging optical system having a full angle-of-view A larger than 360/n degrees where n is a natural integer greater than or equal to 2 and a two-dimensional imaging element wherein in each imaging optical system, the magnification per unit angle-of-view monotonically increases between 0 and 360/n-degrees and varies with a different rate between 360/n degrees and A.
