Document Type and Number:
WIPO Patent Application WO/2018/070680
Kind Code:
A1
Abstract:
A wide-angle lens group according to the present invention is a group of wide-angle lenses for collecting light from a subject, wherein the lens group is formed along a three-dimensional trajectory which is obtained by sequentially arranging respective cross sections of a fisheye lens, a concave lens, and a convex lens on one plane, and rotating the cross sections of the fisheye lens, the concave lens, and the convex lens within a particular angle range with respect to a virtual rotation axis, which is perpendicular to a straight line connecting the centers of the cross sections of the fisheye lens, the concave lens, and the convex lens and disposed to be spaced from the cross section of the convex lens in a direction opposite to the cross section of the concave lens.
