Description

technical field [0001] The application belongs to the technical field of optical elements, and in particular relates to an optical imaging lens, a camera module and electronic equipment. Background technique [0002] As users demand for shooting with a large field of view, more and more electronic devices are equipped with optical imaging lenses with ultra-wide angles. However, due to the large distortion of the ultra-wide-angle optical imaging lens, and the greater the angle, the greater the distortion, resulting in a more obvious distortion of the captured image, which makes the proportion of the image uncoordinated. At present, software is generally used to correct distortion of captured images. On the one hand, the ability of software to correct distortion is limited. On the other hand, software correction needs to consume additional power consumption, resulting in serious heating of electronic equipment during shooting.
