Abstract

The invention relates to an optical imaging system, an imaging module, an electronic device and a driving device. The optical image capturing system includes, in order from an object side to an imageside along an optical axis, a first lens group having negative refractive power; a second lens group having positive refractive power; a third lens group having positive refractive power; a fourth lens group having positive refractive power; and a diaphragm provided on the object side of the third lens group. According to the optical imaging system, the lenses in the system are grouped, so that the system can give consideration to a wide viewing angle and high resolution capability, and has the characteristic of miniaturization.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical imaging system, an imaging module, an electronic device and a driving device. Background technique [0002] In recent years, with the development of in-vehicle technology, driving assistance systems, driving recorders, and reversing cameras have higher and higher requirements for the application of in-vehicle cameras, which not only require the cameras to be small and lightweight, but also require Higher pixel image quality. [0003] However, the image pixels captured by traditional on-board cameras are of low quality, which cannot enable the above-mentioned on-board systems or devices to accurately judge the environmental information around the vehicle in real time and prompt the driver to make timely warnings or avoidance. risk. Contents of the invention [0004] Based on this, it is necessary to provide an improved optical imaging system for the problem ...
