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.
本申请涉及一种光学成像系统、成像模组、电子装置及驾驶装置。光学成像系统沿着光轴由物侧至像侧依序包括具有负屈折力的第一透镜组;具有正屈折力的第二透镜组;具有正屈折力的第三透镜组;具有正屈折力的第四透镜组;以及光阑,设于所述第三透镜组的物侧。上述光学成像系统通过将系统中的透镜分组化,是系统可以兼顾广视角以及高解像能力,同时还具有小型化的特点。
