Abstract

The invention discloses a lens imaging system of a high-pixel fish-eye lens. The lens imaging system is divided into a first group and a second group. The first group is composed of a first lens, a second lens and a third lens. The first lens and the second lens are both concave lenses, and the third lens is a positive lens. A first face and a second face of the first lens are sequentially a convex face and a concave face, a first face and a second face of the second lens are sequentially a convex face and a concave face, and a first face and a second face of the third positive lens are both convex faces. The second group is composed of a fourth lens, a fifth lens and a sixth lens, and the fourth lens and the fifth lens are both positive lenses. A second face of the fourth lens is a convex face, a first face and a second face of the fifth lens are both convex faces, a first face and a second face of the sixth lens are sequentially a concave face and a convex face, and the fifth lens and the sixth lens are adhered together. A diaphragm is arranged between the two groups of lenses. The lens imaging system can reduce possibility of dark corners generated when light reaches a sensitization piece and can correct distortion well for a large field angle.

Description

technical field

[0001] The invention provides a lens imaging system of a high-pixel fisheye lens, and particularly relates to a lens imaging system with the advantages of low cost, ultra-wide angle, small F-θ distortion, loose tolerance requirements, and high imaging quality. Fisheye camera lens for outdoor sports. Background technique

[0002] At present, some outdoor extreme sports, such as skiing, surfing, diving, skydiving, racing, diving, etc., cannot solve the problem of taking pictures at any place and in any direction under severe vibration, high pressure and other environments, and require good camera effects , the distortion is small enough, so the development of a camera that takes pictures while exercising has a very broad market prospect, and the development of this lens is based on this background.

[0003] The market prospect of this lens is very broad, and it can be widely used in some outdoor extreme sports, such as skiing, surfing, diving, skydiving, racin...
