Description

Slewing mechanism and periscopic camera module thereof
Technical Field
The invention relates to the field of camera shooting, in particular to a rotating mechanism and a periscopic camera shooting module thereof.
Background
Recently, as mobile terminals such as smart phones, which have become widespread due to the development of mobile communication technology, smaller and lighter camera modules have appeared, and therefore at least one or more camera modules are arranged on a mobile terminal body. The demand of the customer for designing the camera module is increasing day by day, and the customer not only requires the camera module configured on the mobile terminal to have the characteristics of high capacity and high performance, but also requires the development of the camera module meeting the standard of a digital still camera (DSLR), and the development of the camera module needs to meet the development trend of miniaturization and lightness while maintaining high performance and high capacity.
Wherein periscopic camera module is through the mode of settling the reflection prism at the front end of traditional prism, will reflect from the light beam of vertical direction incidence camera module front end, make the light beam can be followed vertical direction and turned to vertical direction mutually perpendicular's horizontal direction, reachs the sensitization chip behind rethread camera lens subassembly and the color filter, and then guarantee long focus camera module reduces long focus camera module's height when satisfying long focus shooting effect, can install the horizontal mode of camera module in electronic equipment. Therefore, the periscopic camera module can realize the requirements of terminal equipment miniaturization and optical zooming to a great extent, reasonably changes a longer lens structure through converting the angle of incident light, and reduces the height of the module.
The camera module realizes an Optical Auto Focus function (hereinafter referred to as an AF function) and an Optical anti-shake function (hereinafter referred to as an OIS function) through a motor during shooting, wherein the AF function and the OIS function are the Optical Image Stabilization functions. The AF function refers to a function of focusing an object by linearly moving a lens system in an optical axis direction by a motor to adjust a focus to produce a sharp image at an image sensor (CMOS, CCD, etc.) located at the rear of the lens. The OIS function is a technique for compensating for image blur by motor anti-shake control when a lens is shaken due to shake, and an image sensor captures an image of light incident through a lens system and converts the image into an image signal.
Simultaneously, the shooting angle of the camera module is relevant with optical lens's focal length, and the less the angle of shooing that optical lens's focal length is big more, and the camera module is just stronger to the shooting ability of near scenery this moment, and correspondingly, the more the angle of shooing that optical lens's focal length is big more is little, and the shooting ability of the camera module to distant scenery is just stronger this moment. The telephoto lens has a larger focal length, so that the photographing distance can be longer, and photographing can be performed at a long distance, so that the body shape of the telephoto lens is usually larger, and the height of the camera module is larger due to the substantially-shaped telephoto lens. Further, it is difficult to mount an appropriate motor on the telephoto lens, and the entire size may be excessively large.
