Problems solved by technology

The disadvantage of this solution is that the fixed-focus module of each camera is limited by the thickness of the mobile phone, it is difficult to achieve the shooting effect of large focal length and large magnification, and the images of different focal lengths have different viewing angles, and algorithms are required for image processing when zooming; at the same time , when adjusting various focal lengths, it is necessary to open a corresponding number of openings on the shell of the mobile phone to install the camera, which affects the appearance quality of the mobile phone

Embodiment Construction

[0054] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings.

[0055] When using terminal products such as mobile phones to take pictures, due to the influence of shooting distance or composition design, users often need to zoom in on the image. However, as the magnification increases, pure digital zoom will seriously sacrifice image resolution. More and more mobile phone camera modules have added the optical zoom function, which optically ensures that images with multiple fixed focal lengths can be collected, and combined with the digital zoom algorithm, it can maintain image resolution while covering a wider zoom range force. At present, the widely used optical zoom hardware solution on mobile phones is a dual fixed-focus module structure composed of a main camera with a standard focal length and a sub-camera with a long focal length....

Abstract

The invention provides a camera module and electronic equipment, and aims to realize a zooming function on the basis of adopting a single camera. The camera module comprises a prime lens group, a photosensitive element and a zooming device. The prime lens group comprises a light inlet side and a light outlet side. The photosensitive element is positioned on one side of the light-emitting side; thezooming device comprises a first zooming assembly, the first zooming assembly comprises a zooming lens group and a driving part, and the driving part of the first zooming assembly is used for drivingthe zooming lens group of the first zooming assembly to move from a first working position in the zooming device to a second working position in the zooming device; when the zoom lens group of the first zoom assembly is located at the first working position, the projection of the zoom lens group of the first zoom assembly on the first plane is not overlapped with the projection of the prime lensgroup on the first plane; when the zoom lens group of the first zoom assembly is located at the second working position, the optical axis of the zoom lens group of the first zoom assembly coincides with the optical axis of the prime lens group; and the first plane is a plane perpendicular to the optical axis of the prime lens group.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a camera module and electronic equipment. Background technique [0002] In order to enhance the competitiveness of electronic devices such as mobile phones and tablet computers, integrated telephoto cameras have become one of the main development trends of current electronic devices. Telephoto cameras, these mobile phones rely on two or more cameras to achieve zooming. Different cameras have different focal lengths. In specific applications, the camera can be switched according to the actual shooting needs of users to achieve zooming. The disadvantage of this solution is that the fixed-focus module of each camera is limited by the thickness of the mobile phone, so it is difficult to achieve the shooting effect of large focal length and large magnification, and the images of different focal lengths have different viewing angles, and algorithms are required f...
