Abstract

The invention relates to the technical field of optical imaging, in particular to an optical imaging system, an image capturing module, electronic equipment and an automobile. The optical imaging system comprises, in order from an object side to an image side: a first lens having negative refractive power; a second lens element with negative refractive power; a third lens with positive refractive power, wherein the object side surface and the image side surface of the third lens are convex surfaces near the optical axis; a fourth lens with positive refractive power, wherein the object side surface of the fourth lens is a concave surface near the optical axis, and the image side surface of the fourth lens is a convex surface near the optical axis; a fifth lens with negative refractive power,wherein the object side surface of the fifth lens element is a concave surface near the optical axis, and the image side surface of the fifth lens is a convex surface near the optical axis; a sixth lens with positive refractive power, wherein the object side surface and the image side surface of the sixth lens are convex surfaces near the optical axis; the optical imaging system satisfies the following conditional expression: 5 < f123/f < 7. According to the optical imaging system, the imaging resolution of the system can be improved, so that the imaging quality is improved.

Description

Technical field [0001] The present application relates to the field of optical imaging, and in particular, to an optical imaging system, an image forming module, an electronic device, and a car. Background technique [0002] With the development of the in-vehicle industry, the application of ADAS and DMS's car driving, not only requires monitoring of the driver's status, according to the eye state, closing the number of eyes, closed eye, yawning, etc. It is required to monitor the status of the driving habits to fully determine the change of the driver's driving environment, thereby presented a safety warning to remind the driver's driving status and make a prevention in advance. [0003] Therefore, it is necessary to provide an optical imaging system to provide a driver, passenger's condition or a driving environment of driving ambient status, to the driving control system, so that the system makes accurate analysis and judgment, ensuring driving safety and environmental visuali...
