Abstract

The invention discloses a camera module and an electronic device. The camera module comprises an image sensor and a prime lens. The prime lens and the image sensor are correspondingly arranged; the prime lens comprises a first lens group and a second lens group which are arranged at intervals along the optical axis of the prime lens and can move relatively along the optical axis. The first lens group and the second lens group can move along the optical axis towards the side far away from the image sensor so that the prime lens is enabled to move from the first position to the second position.When the prime lens is located at the first position, the camera module focuses outside the image sensor, and when the prime lens is located at the second position, the camera module focuses on the image sensor. Thus, the camera module can be packaged into electronic devices such as a mobile phone with a short total length when the camera module is located at the first position, the thickness of the electronic devices such as the mobile phone cannot be increased, and lightening and thinning of the electronic devices are facilitated.

Description

technical field

[0001] The present application relates to the field of electronic technology, in particular to a camera module and an electronic device. Background technique

[0002] In related technologies, as the number of pixels increases, the target area of ​​the sensor of the camera will also become larger and larger. When the target surface of the sensor continues to grow larger and the field of view remains basically unchanged, the focal length of the matching lens will also continue to increase. When the focal length of the lens increases, the total length of the lens will also increase accordingly. This will make the body of electronic devices such as mobile phones thicker and thicker. Secondly, as the aperture and resolution indicators increase, the lens must use more lenses to achieve such indicators. However, the increase of lenses will increase the complexity of assembly and reduce the product assembly yield. Contents of the invention
