カメラモジュールおよび端末デバイス
Document Type and Number:
Japanese Patent JP7405495
Kind Code:
B2
Abstract:
Embodiments of this application disclose a camera module and a terminal device. The camera module includes a plurality of lenses sequentially arranged from an object side to an image side along a direction of an optical axis. At least one of the plurality of lenses is a free-form lens. The free-form lens is a non-rotationally symmetric lens, the 1st lens in the plurality of lenses in a direction from the object side to the image side is a first lens, a distance on the optical axis between an object-side surface of the first lens and an imaging surface is TTL, an effective focal length of the camera module is EFL, and TTL/EFL≤2.0, to implement relatively short TTL. In this application, at least one lens of the camera module is limited to being a free-form lens, to suppress an optical distortion problem of the camera module. An imaging effect of the camera module can be ensured even in the case of an ultra wide angle. In addition, a relatively short total length of the camera module can be implemented, thereby implementing a compact structure of the camera module.
