Abstract

The invention relates to the technical field of optical imaging devices, and particularly discloses a camera lens, a camera module, electronic equipment and an automobile. The camera lens comprises afirst lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are sequentially arranged from an object side to an image side, wherein the first lens element has negativerefractive power, the second lens element has negative refractive power, the third lens element has positive refractive power. the fourth lens element has positive refractive power, the fifth lens element has negative refractive power, The sixth lens element has positive refractive power. The camera lens can directly keep small size and light weight without increasing the number of lens pieces, can keep good optical performance, and can well capture details of a shot object.

Description

technical field [0001] The invention relates to the technical field of optical imaging devices, in particular to a camera lens, a camera module, electronic equipment and a car. Background technique [0002] At present, with the continuous improvement of road traffic safety and car safety requirements, and the rise of surround view cameras, ADAS (Advanced Driving Assistant System: Advanced Driver Assistance System) and driverless markets, more and more car lenses are used in car assistance. in the driving system. At the same time, people have put forward higher requirements for the imaging quality and picture comfort of vehicle-mounted lenses. Surround view camera, through the reasonable distribution of multiple large wide-angle lenses on the body, stitches together the bird's-eye view images from all directions on the top of the car, so that the driver can see the images around the car clearly, and can effectively avoid reversing, rolling, scratching the bumper and the whee...
