Abstract

The invention discloses a lens, a camera module and an electronic device. The lens comprises a lens cone, a lens group and a first polarization element. The lens cone is provided with an opening and an accommodating space communicated with the opening. The lens group is arranged in the accommodating space. The first polarization element is arranged corresponding to the opening and seals the opening, the polarization direction of the first polarization element is changed under the condition that the first polarization element is powered on, and / or the polarization direction of the first polarization element is changed under the condition that the first polarization element rotates relative to the lens cone. According to the lens provided by the embodiment of the invention, the first polarization element is arranged at the opening, and the polarization direction of the first polarization element can be changed, so that the light transmission amount of the first polarization element is changed, the size of the aperture of the lens can be controlled, and the light incoming amount of the lens can be controlled. Besides, the size of the aperture can be changed without controlling the physical position of an additional light blocking element, the precision of adjusting the aperture is easy to control, and the effect is better.

Description

technical field [0001] The present application relates to the technical field of imaging devices, in particular to a lens, a camera module and an electronic device. Background technique [0002] The brightness of the image captured by the camera is related to the exposure of the image, and the exposure of the image is related to the amount of light entering the camera. When the image is overexposed, the brightness of the image is too high; when the image is underexposed, the brightness of the image is too low. Whether the brightness of the image is too high or too low, it is not conducive to improving the clarity of the image. Therefore, how to adjust the amount of light entering the camera to adjust the exposure of the image has become a technical problem to be solved. Contents of the invention [0003] The application provides a lens, a camera module and an electronic device. [0004] The lens of the implementation mode of this application includes: [0005] a lens b...
