Split array camera module

This creation relates to the field of camera modules, and further relates to a split array camera module.

With the continuous development of smart devices, the requirements for camera modules are getting higher and higher. For example, in the past two years, the camera of smart phones has changed from a single camera to a dual camera, and the development of dual camera modules has become an important trend in the development of mobile phone camera modules.

Simply put, the dual camera can capture images with the cooperation of two cameras, enabling a richer image acquisition function. The existing dual cameras can be divided into two categories according to their functions: one is to use three cameras to generate stereo vision, to obtain the depth of field of the image, to use the depth information to perform background blur, 3D scanning, auxiliary focus, motion recognition, etc., or to use two The information of the picture is fused; the other is to use two different images on the left and right to fuse, in order to obtain higher resolution, better color, dynamic range and other better image quality or optical zoom function.

On the other hand, the picture element requirements of the camera module are getting higher and higher, and the number of lenses of the lens is increasing. From the original two or three pieces to the current five, six or even more pieces, the camera module facing the high picture element faces On the one hand, it requires a small volume, on the other hand, it requires the problem of good optical imaging quality, and the module for multi-camera is also faced with such a problem. How to make the module as a whole suitable for high picture elements, and stable and safe Two or more camera modules cooperate to form an integral module to meet the requirements of the multi-camera module in the development of the existing camera module, which is a problem to be solved.

When the camera is installed in an electronic device, such as a smart phone, the external needs to be flat, and the appearance of the two cameras is beautiful. Therefore, how to assemble the external rules of the two camera modules is one of the problems to be considered in the multi-camera module.

Furthermore, the consistency of the optical axis between multiple cameras is an important aspect of the optical design of the multi-camera camera module. How to ensure that multiple camera modules can be assembled in one body and ensure the consistency of the optical axis. This is a multi-camera. A problem to be considered in the manufacture of camera modules.

Further, two cameras cooperate with each other to collect image information, and the accuracy of the image acquisition and the image quality are closely related to the incident light of the two cameras. The optical axis consistency between the two cameras is to ensure the camera module. The basis of imaging quality. That is to say, how to improve the optical axis consistency of the two camera modules on the basis of stably and compactly fixing two cameras, or to make the error within a predetermined range, thereby improving the precision of the installation and making it more accurate Good image quality is another important issue to consider when developing a dual camera.
