Abstract

The invention relates to a camera module. The camera module comprises a driving motor, a first lens module, a second lens module, a lens seat, an imaging unit and a casing, wherein the lens seat comprises an accommodation chamber, and the first lens module and the second lens module are accommodated in the accommodation chamber. The camera module is characterized in that the first lens module and the second lens module are respectively fixed at two opposite ends of the lens seat, the imaging unit is accommodated in the accommodation chamber and is fixed with the casing relatively, the imaging unit is arranged between the first lens module and the second lens module, the first lens module, the second lens module and the imaging unit realize optical alignment, and the driving motor is used for driving the lens module to move relative to the imaging unit so as to change a relative distance between the first lens module and / or the second lens module and the imaging unit.

Description

technical field [0001] The invention relates to a camera module, in particular to a camera module with a bidirectional imaging module. Background technique [0002] With the development of camera technology, camera modules are widely used in camera devices for various purposes. The combination of camera modules and various portable electronic devices such as mobile phones, video cameras, computers, etc. is favored by many consumers. . [0003] The camera module generally includes a driving motor, a lens module driven by the driving motor, and a photosensitive component optically aligned with the lens module. The lens module may include one or more lenses and lens groups, and the lenses and lens groups are optically aligned with the photosensitive component. Preferably, the center point of the photosensitive component is located on the optical axis of the one or more lenses and lens groups. The driving motor drives the lens or lens group of the lens module to move relative ...
