Abstract

The invention provides an optical imaging system, and the system sequentially comprises, from an object side to an image side, a first lens with positive focal power, wherein the object side surface of the first lens is a convex surface; asecond lens with negative focal power, wherein the object side surface and the image side surface of the second lens are concave surfaces; a third lens with positive focal power, wherein the object side surface and the image side surface of the third lens are convex surfaces; a fourth lens with positive focal power, wherein the object side surface and the image side surface of the fourth lens are convex surfaces; and a fifth lens with negative focal power, wherein the object side surface and the image side surface of the fifth lens are concave surfaces. The optical imaging system has the advantages of high pixel resolution and small size. In addition, the invention also provides an image capturing device and electronic equipment.

Description

technical field [0001] The invention relates to optical imaging technology, in particular to an optical imaging system, an imaging device and electronic equipment. Background technique [0002] With the popularity of automobiles, traffic accidents caused by factors such as fatigue driving occur frequently. With the rapid development of the vehicle industry, vehicle driving technologies such as ADAS (Advanced Driving Assistant System) and DMS (Driver Monitor System) are gradually becoming mature, and the development of these vehicle technologies is inseparable from camera technology. However, the existing camera devices that meet the requirements of vehicle miniaturization have low resolution and cannot monitor the state of the driver well. The information can be used to speculate and judge whether the driver is driving in fatigue, so as to provide early warning and improve driving safety. Contents of the invention [0003] In view of this, the present invention provides ...
