Multi-camera module

Abstract

The embodiment of the invention discloses a multi-camera module. The multi-camera module comprises multiple lens, an IR switcher, an optical lens group and an image sensor, wherein multiple lens at least are one telephoto lens and one wide-angle lens; the number of the IR switcher is at least one, and the IR switch is arranged between the lens and the image sensor for controlling whether the light ray passing through the lens has emitted; the optical lens group is used for projecting the light ray emitted from the IR switcher to the image sensor. Multiple lenses share one image sensor, the IR switcher is used for controlling the light ray projected to the image sensor and projecting the light ray emitted from each lens to the image sensor through the optical lens group. By arranging the telephoto lens and the wide-angle lens, a problem that the existing camera module is single in function is solved; multiple lenses share one image sensor, the manufacturing cost of the whole camera module and the use cost of the user are lowered, thereby facilitating the multi-camera module to develop towards a miniaturization and high-integration direction; and the good social and economic benefit is provided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photography equipment, and in particular to a multi-camera module. Background technique [0002] As users have higher and higher requirements for the quality of imaging pictures, the continuous development of camera and photography equipment technology is required to obtain high-quality and high-definition pictures. [0003] The optical quality of the lens and the size of the sensor determine the imaging quality of the camera, and with the light and thin requirements of camera equipment (such as mobile terminals), the sensor size and the optical quality of the lens are limited. Moreover, the pixels of a single camera face a bottleneck when developing to a higher level, and it is impossible to obtain high-quality pictures by increasing the pixels. For example, for mobile phone cameras, 20 million pixels have reached the limit. In addition, users do not need mobile phones to achieve s...

Problems solved by technology

[0005] However, in the existing dual-camera modules, one camera is often equipped with an image sensor, that is, the camera and the image sensor are configured one-to-one. Due to the high cost of the image sensor, the camera module with this structure is not only costly but also functional. Single, also leads to the large size of the entire camera module, which is not conducive to miniaturization and high integration
