Abstract:
1. An image pick-up device in which a part to be photographed is divided into a plurality of parts to be photographed, a plurality of image pick-up means for individually photographing the respective parts to be photographed are provided in the same planes along a circumferential direction, and images from the image pick-up means are combined together to obtain a wide angle image, wherein the image pick-up means respectively include equivalent convex lenses and an image pick-up parts on mutually parallel planes and the equivalent convex lenses and the image pick-up parts are respectively displaced relatively along the mutually parallel planes, wherein principal rays which pass through a Gaussian area are selected among principal rays passing through the centers of diaphragms provided in the image pick-up means, straight line components are extended in object spaces in the principal rays to set points where the straight line components intersect an optical axis as NP points, and other NP points are arranged within an NP point area of a sphere having any one NP point as a center among the NP points in the respective image pick-up means.
