Huawei P9 adopts SUMMARIT series lenses from Leica, Germany. Each P9 mobile phone lens has been designed and screened by Huawei and Leica engineers. Leica optical engineers have set strict screening standards for each group of lenses, including definition and glare. The ghosts and other indicators are in line with Leica's precision design standards, making the precision and quality of the P9 lens much higher than that of the ordinary mobile phone lens, ensuring that the P9 has the best image performance. When every light enters the lens, reaches the sensor, and then goes through the whole process of imaging, it perfectly reproduces the stunning imaging effect of Leica on the traditional camera.
The fusion design of 2.5D glass and curved metal back shell, coupled with the new generation of Unicorn eight-core processor and larger operating memory, Huawei P series new generation flagship mobile phone P9 shines. Among them, Huawei's dual camera imaging technology, Leica SUMMARIT series lens, coupled with large aperture camera mode and hybrid focus technology, the professional camera effect brought by the domestic and international attention, will bring about a major change in mobile photography? Shanghai Microtechnical Research Institute SITRI brings you a deep understanding of this “Fixed Vision†Huawei P9.
Major Components
What is the dual camera technology, what is the laser focus, and which manufacturer is the fingerprint identification chip that Huawei P series first joined? Let SITRI reveal the sensor technology used in the P9.
It can be seen from the above table that the gyroscope & accelerometer and electronic compass in Huawei P9 use the common ST LM6DS3 and AKM AK09911. These two sensors have a high frequency in previous mobile phones. SITRI has shared specific information many times in the previous disassembly report, and will not analyze it this time. Let's start with the rear dual cameras that are most concerned about in the industry.
Rear dual camera
The Huawei P9 uses the Leica SUMMARIT series of dual lenses for better brightness and clarity. The rear 12 megapixel black and white and color dual camera, work together in the shooting, black and white lens (full image sensor) to capture details, color lens (RGB image sensor) capture color, plus Huawei's unique image synthesis algorithm and with Leica Co-developed image quality algorithm, Huawei is committed to creating a P9 that can produce excellent results for professional cameras.
The rear dual image sensor module measures 19.75 mm X 18.40 mm X 5.10 mm.

Laser ranging sensor
Huawei P9 supports three types of focus modes: laser focus (suitable for close-up photography), contrast focusing (for complex scenes), and deep focus (suitable for deeper depth of field). At the moment of taking pictures, P9 will automatically select the most suitable and fastest focusing method. One of the highlights of its focus is the addition of a laser focus function, which adds a laser range sensor to the side of the rear dual camera.
Laser focusing is to calculate the distance of the target by recording the time difference between the infrared laser from the emission to the reflection. The advantage is that it can be applied even in low light conditions, but the disadvantage is that the target distance can not be too large, but the contrast does not exist in the target. The problem of distance is that the focus is not good in low light conditions. With the addition of laser focusing, the Huawei P9's rear camera can achieve more accurate skin color reduction, dynamic range and detail in the backlight environment, while night shooting is also more powerful.
The Huawei P9 laser ranging sensor uses the ST Microelectronics-VL53L0X with a package size of 4.40 mm X 2.40 mm X 1.00 mm.

For the fingerprint sensor of Fingerprint Cards, SITRI has done a specific process analysis and circuit analysis for one of the FPC1020AM. For details, please refer to the specific analysis report of SITRI.
MEMS microphone
Huawei P9 has two microphones, all from GoerTek. These two are not the same as Mark, and the MEMS Die inside is all the same.
Both microphones are available in a package size of 3.75 mm X 2.70 mm X 1.20 mm.
