In 2016, the mobile phone industry is highly competitive, and domestic and foreign mobile phone manufacturers have tried their best to win the attention of consumers. As a key point in the mobile phone, the camera is constantly innovating. The PDAF replaces the conventional AF, which greatly improves the speed of focusing; the OIS (Optical Image Stabilization) module makes the camera more intelligent; and the double-shot that mimics the human eye is to raise the current level of photography to a new one. The height: the dark state effect is improved, the first camera to focus, the virtual aperture, 3D scanning and other innovations are to make consumers overwhelmed.
Camera three key device technology trends
What are the hot spots or breakthroughs in mobile phone camera technology in 2017? The three key components of the camera are the chip, lens and motor, naturally starting from these three devices.
The key point of the chip is the size. 1. The unit pixel size is larger: more flagship machines increase the pixel size of the rear camera from 1.12um to 1.25 or even 1.4um. The unit pixel area of ​​the chip is larger, but the structure remains unchanged under the requirement of pixel boosting, which makes the captured image more effective; 2. The unit pixel is small: 1um 13M/16M is also in the mobile phone factory. The focus of attention, it can make the camera module size smaller, is the gospel of each ultra-thin mobile phone program, of course, due to the chip factory process, the pixel size chip has not been mass-produced.

Another hot chip technology is the color filter. There are two innovations in color filter: one is the RGBW/RWB solution, and the other is the Dual PD solution. With the improvement of the computing power of the mobile phone processor and the optimization of the chip process, the RGBW/RWB scheme has gradually weakened its power consumption and high price, and the scheme has become more and more mature. This scheme can greatly increase the brightness of the image under low light. It is unmatched by conventional RGB chips. The Dual PD solution is an upgraded version of the PDAF solution. By increasing the area of ​​the PD pixel, it can solve the problem that the current PD chip is unstable in PD output under low light, and the dark state is slow, and with the innovation of chip technology, it is 2018. It is possible to develop a 4PD sensor chip in the year.

There is also a subversive breakthrough on the chip - the chip focus scheme (MEMS focus module), which achieves focus by moving the chip, enabling the FF structure module to implement the AF function, which is a leap forward in the size of the module. .
The key technology of the motor is OIS on the one hand, but the current OIS motor is a translational solution with limited anti-shake capability. Now motor manufacturers have designed a 5-axis OIS solution, which has a large anti-shake angle and good image clarity, and is an upgraded version of the OIS solution. On the other hand, the motor is also very important in the push of the double camera, especially the relatively high-predictive double-shot, which enables the camera module to achieve 3x optical zoom and the amount of the periscope motor through two lenses with different focal lengths. The production will be another milestone in the development of the camera.
