Abstract

The invention relates to an imaging lens, an image capturing device, an electronic device and a driving device. The imaging lens comprises, sequentially from an object side to an image side along an optical axis, a first lens element with negative refractive power ; a second lens element with positive refractive power; a third lens element with negative refractive power; a fourth lens with refractive power, the object side surface and the image side surface being convex surfaces; the fifth lens with refractive power, the object side surface and the image side surface being concave surfaces; a sixth lens element with positive refractive power; a seventh lens with refractive power, the image side surface being a convex surface; and a diaphragm arranged on the object side of the fourth lens. The imaging lens can be miniaturized while having high resolution capability, and is low in cost and suitable for batch production.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an imaging lens, an imaging device, an electronic device and a driving device. Background technique [0002] With the development of science and technology, advanced driving assistance system (Advanced Driving Assistant System, ADAS), driver monitoring system (Driver Monitor System, DMS), driving recorder, reversing camera and other vehicle camera technologies are gradually mature. All the above-mentioned technologies need to obtain clear road surface information images or clear driver driving images in order to more accurately judge the road surface conditions or the driver's driving state, so as to provide protection for driving safety. [0003] Traditional vehicle lenses usually use more than six lenses to obtain higher resolution capabilities. However, increasing the number of lenses will affect the miniaturization of the lens, which is not conducive to the installat...
