The camera included in the smart phone is a major function, and Most people are more accustomed to using a mobile phone camera instead of a traditional camera to record life and share directly to the Internet through the smart phone. In particular, in response to various needs and developments, the specifications of various related hardware and software parts have been constantly evolving, so people gradually become accustomed to using the camera function of the mobile phone to replace most of the cameras.

It is worth mentioning that the current mobile phone market is still maintaining a rapid growth trend, especially the growth of smart phones is more rapid. Also, because the user's requirements for the quality of the camera are getting higher and higher, the pursuit of superior performance of the camera module has become a key technical field for the fierce competition of major mobile phone manufacturers. In 2014, with Yulong releasing a smartphone with dual cameras, the camera module entered the era of dual cameras. For the original dual camera, its main function is in 3D display effect and shooting ability, but the pixel is too low and the picture quality is not high, there is still much room for improvement for the dual camera.

Therefore, the development trend of the camera module of the smart phone is developing toward the dual camera technology, and since the smart phone has strict requirements on the thickness, it is necessary to provide an excellent shooting effect without increasing the volume too much. In other words, the overall height of the camera module of the smart phone cannot be too high, which limits the size of the sensor chip to be too large, and the imaging effect cannot be further improved. Therefore, in order to improve the image quality, a dual camera solution is adopted. However, the current dual-camera scheme uses the same pixel RGB+MONO chip scheme. Since the algorithm needs to synthesize the image, it is necessary to ensure the image consistency, and the lens of the same specification is used. However, the definition of the pixels of the dual camera is not a simple addition. Therefore, it is necessary to improve the performance of the dual camera module without increasing the cost, so that the user has a better experience, especially to enhance the dark state effect.
