The aperture of the lens is mainly used to adjust the size of the aperture or opening of the lens, so as to control the amount of light entering the lens, so that the image can be correctly exposed. In this way, the image will not be too bright in a well-lit scene, and at the same time, the image will not be too dark in a dark environment. On the other hand, the size of the aperture will also affect the depth of field of the image. The smaller the aperture, the longer the depth of field. The larger the aperture, the shorter the depth of field. Long depth of field is particularly important in some surveillance scenarios, such as narrow passages or parking lots. Conventional lens aperture control methods are mainly fixed aperture, manual aperture, automatic aperture and electric aperture....
