Embodiment Construction

[0037] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0038] As the camera function is more and more valued by users, the current terminal equipment usually adopts a multi-camera system design to meet the shooting needs in different scenarios. For example, when the shooting scene requires a wider field of view, use a wide-angle camera Shooting; when the shooting target is far away, use the far-focus camera for shooting; when shooting close-ups, use the macro camera for shooting to achieve the best photo experience. However, existing terminal devices need to be equipped with multiple independent cameras to adapt to different scenarios, that is, terminal devices need to be equipped with multiple lenses and a corresponding number of image sensors, such as figure 1 As shown, the terminal equipment includes three independent cameras, and each camera include...

Abstract

The embodiment of the invention provides a lens switching method and device, the lens switching device comprises a camera module, and the camera module comprises M lenses, N image sensors and a motor,wherein M is a positive integer greater than or equal to 2, N is a positive integer greater than or equal to 1, and M is greater than N. The method comprises the steps of determining a to-be-switchedlens, and switching the to-be-switched lens to a position corresponding to a target sensor, thereby realizing buckling recombination of the lens and an image sensor. The method can enable the numberof the image sensors to be smaller than the number of the lenses, reduces the number of the image sensors while meeting the photographing demands of a user, and reduces the cost of the terminal equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a lens switching method and device. Background technique [0002] At present, the camera function is more and more valued by users, and has become one of the core functions of mobile terminal equipment. In order to meet the needs of users for taking pictures in different scenes, the current mobile terminal equipment is equipped with a plurality of independent cameras (camera modules) to adapt to different shooting scenes. For example, when the shooting target is far away, a telephoto camera is used for shooting; when the shooting target is very close, a macro camera is used for shooting. Usually a camera includes an image sensor and a lens. Equipping a mobile terminal device with multiple independent cameras will significantly increase the manufacturing cost of the device. Therefore, how to reduce the manufacturing cost of the device while meeting the shooting requirements of...
