Title:
An optical system and an imaging device
Document Type and Number:
Japanese Patent JP6004073
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a new imaging system that can photograph images with homogeneous quality over a wide imaging range, and an image formation optical system used for the same.SOLUTION: There is provided an imaging system having n or more imaging optical systems in combination, the imaging optical system comprising an image formation optical system having a total angle of view of A(degrees) larger than 360/n (n is an integer of 2 or more), and a two-dimensional solid imaging element SNC converting light condensed by the image formation optical system WLC into image signals. In the image formation optical systems WLC and WLD in the individual imaging optical systems, the magnification per unit angle of view monotonously increases from an angle of view of 0(degree) to 360/n(degrees), and the rate of increase of the magnification monotonously decreases after exceeding an angle of view of 360/n(degrees) to the total angle of view of A(degrees).SELECTED DRAWING: Figure 10
