Abstract

One embodiment of the invention discloses an ultra-wide image pickup optical system. The system is provided with, sequentially from an object plane to an image plane along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens. The lenses of the optical system meet the following conditions: -0.2<f/f1<-0.09; -0.25<f/f2<-0.15; -0.3<f/f3<-0.19; 0.17<f/f4<0.23; 0.02<f/f5<0.07; 0.11<f/f67<0.18; and 0.12<f/f8<0.31. The other embodiment of the invention discloses an image pickup module. The embodiments of the invention are applicable to the fields of panoramic VR cameras and 360-degree dead-zone-free monitoring. The number of the lenses is moderate, and the structure is simple. Moreover, the ultra-wide image pickup optical system and the image pickup module have excellent performances of 240-degree ultra-wide field and eight megapixels.

Description

[0001] Technical field: [0002] The invention relates to a wide-angle camera optical system and a camera module for its application, in particular to an optical system suitable for panoramic VR cameras and 360° monitoring without dead angles and a camera module for its application. [0003] Background technique: [0004] Existing optical systems or camera modules used in the field of panoramic VR cameras and 360° monitoring without dead angle generally have the defects of too many lenses and complex structures. [0005] Invention content: [0006] In order to overcome the problems of too many lenses and complicated structures in existing optical systems or camera modules, the embodiments of the present invention provide an ultra-wide-angle camera optical system on the one hand. [0007] The ultra-wide-angle imaging optical system is provided in sequence along the optical axis from the object plane to the image plane: a first lens, a second lens, a third lens, a fourth lens, a...
