Abstract

The embodiment of the invention discloses an optical system, a lens module and electronic equipment, which belong to the technical field of optical imaging. The optical system sequentially comprises afirst lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object plane to an image plane along an optical axis. The optical system satisfies the following conditional expressions: 33 degrees < (HFOV * f) Imgh < 35 degrees, HFOV is a half of the maximum field angle of the optical system, f is the focal length of the optical system, and Imgh is a half of the image height corresponding to the maximum field angle of the optical system. According to the embodiment of the invention, by reasonably limiting half of the maximum field angle of the optical system, thefocal length of the optical system and half of the image height corresponding to the maximum field angle of the optical system, the good optical performance of the optical system can be maintained, the high-pixel characteristic of the optical system is realized, and the details of a photographed object can be well captured.

Description

technical field [0001] The present application relates to the field of optical imaging technology, in particular to an optical system, lens module and electronic equipment. Background technique [0002] With the development of the automotive industry, the technical requirements for automotive driving assistance cameras such as front view, side view, automatic cruise, driving recorder, and reversing images are getting higher and higher. Among them, the side-view camera is an on-board camera used to monitor the road conditions on the left and right sides of the car. It can be used as the camera system in the advanced driver assistance system to analyze the video content, so that the driver can intuitively view the blind spots on the left and right sides of the car while driving. Identify and monitor internal obstacles and pedestrians. When the car is turning or turning around in special places (such as intersections, roadblocks, parking lots, etc.), the side-view camera can o...
