Abstract

The invention provides an optical imaging system which sequentially comprises,from the object side to the image side: a first lens with positive bending force, wherein the object side surface of the first lens is a plane, and the image side surface of the first lens is a concave surface; a second lens which has positive bending force, and the object side surface of the second lens is a convex surface; a third lens element with positive refractive power; a fourth lens element with positive refractive power; a fifth lens element with negative refractive power; and a sixth lens element with positive refractive power. The image side surface of the fourth lens is glued with the object side surface of the fifth lens, and the image side surface of the fifth lens is glued with the object side surface of the sixth lens. According to the optical imaging system, high pixels are guaranteed, the imaging view field range is widened, the imaging depth range is deepened, and long-distance detail information can be captured. The invention further provides an image capturing module with the optical imaging system, an electronic device with the image capturing module and an automobile.

Description

Technical field[0001]The present invention relates to the technical field of optical imaging, in particular to an optical imaging system, an imaging module, an electronic device and an automobile.Background technique[0002]With the development of the in-vehicle industry, the technical requirements for car driving assistance cameras such as front view, side view, automatic cruise, driving recorder, and reversing video are getting higher and higher. The side-view camera is a vehicle-mounted camera used to monitor the road conditions on the left and right sides of the car. The monitored content can be used as the video analysis content of the camera system in the driver assistance system. These content can assist the driver to intuitively identify when the car is driving Obstacles and pedestrians in blind areas on the left and right sides of the car. At the same time, the obstacle information captured by the side-view camera can be fed back to the car's central system, and the trip comp...
