Periscopic camera module

Abstract

A periscopic camera module comprises a module assembly, a light steering assembly and a light quantity adjusting assembly. The module assembly comprises a photosensitive assembly and a lens assembly, and the photosensitive assembly is provided with a photosensitive path, wherein the lens assembly is correspondingly arranged on the photosensitive path of the photosensitive assembly. The light steering assembly is correspondingly arranged on the light sensing path of the light sensing assembly, and the lens assembly is located between the light sensing assembly and the light steering assembly. The light quantity adjusting assembly is assembled at the end of the light steering assembly, and the light quantity adjusting assembly is located on the light sensing path of the light sensing assembly and used for adjusting the quantity of light received by the light sensing assembly.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular to a periscope camera module. Background technique [0002] In recent years, people's demand for camera functions of portable electronic devices (such as tablet computers, smart phones, etc.) is still increasing rapidly. Features. In particular, due to the application of the periscope camera module, the capability of dual-camera zoom is gradually increasing, for example, its optical zoom capability has been increased from 2x zoom to 3x zoom, or even 5x zoom. In other words, the periscope camera module has greatly changed people's perception of the photography capabilities of portable electronic devices (such as smart phones), and has a broad market prospect. [0003] As we all know, the quality of the image captured by the camera module is closely related to the amount of light entering the camera module, and the amount of light entering the camera module is usually control...

AI Technical Summary

Problems solved by technology

[0004] However, in the process of adjusting the amount of incoming light in the existing periscope camera module 1P, the light is reflected and / or refracted multiple times, and enters and exits multiple interfaces (such as the interface between the liquid crystal dimming device and the prism) etc.), which will cause a loss of light energy, which will result in insufficient light for imaging

In addition, it is difficult for the liquid crystal dimming device 123P to be assembled on the slope of the prism 122P, resulting in high assembly cost of the existing periscope camera module 1P.
