Problems solved by technology

However, the size of the head of the current camera module is more than 3mm. Putting the head of the camera module into the hole will make the size of the screen opening large enough, and the camera module is placed behind the screen. To meet the requirements of the field of view, the side wall of the screen opening cannot affect the camera module to collect light, so the same opening should be relatively large, at least 4.5mm or more
Such a large opening will lead to poor display effect of the screen and affect the user experience of the screen

Abstract

The present invention relates to a split zoom lens comprising: at least two lens components, each of which comprises at least one lens; and a zoom lens which is arranged between the two lens components, wherein the at least two lens components and the zoom lens jointly form an optical system capable of imaging, and the relative position of at least one lens component and the zoom lens is determined by active calibration. The invention also provides a corresponding camera module based on the split zoom lens, and an assembling method of the split zoom lens and the camera module. According to the invention, the optical lens or the camera module with the zoom capability can be realized on the premise of ensuring the small size; and the trepanning size of the trepanning screen can be reduced.

Description

technical field [0001] The present invention relates to the fields of optical technology and photographic technology, in particular, the present invention relates to a split zoom lens, a camera module and a corresponding assembly method. Background technique [0002] With the improvement of consumption standards, the market has higher and higher requirements for mobile phone camera functions. For example, people often expect mobile phone camera modules to have zoom capabilities. However, the market has extremely strict requirements on the size of consumer electronic terminal equipment such as smart phones, especially for mobile phone front camera modules (that is, front camera), its radial size (referring to the dimension perpendicular to the optical axis of the camera module) direction) and axial size (referring to the direction of the optical axis of the camera module, that is, the thickness direction of the mobile phone) are strictly limited, and it is often difficult to ...
