The first level: "isolate the pressure and temptation from the outside world, maintain a normal mentality, return to the origin of things, and grasp the reasonable direction we should do", the second level: "duty is to demand ourselves rather than others, and when problems arise, we should blame ourselves first", and the third level: "duty regulates the attitude of cooperation with others.

CEO Chen Mingyong said: "We are in an era full of pressure, temptation and challenges. We are easily influenced by emotions, leading to fear, irritability and anxiety, and then making wrong judgments. If we can isolate external forces, always keep our responsibilities and go back to the original point of things, think about why we started in the first place. In this way, the way to deal with the problem will become clearer.

Core values: responsibility, user orientation, pursuit of the ultimate, and result orientation.

Dual-core focusing

Dual-core focusing is a focusing technology carried by OPPO R9s on the basis of Sony IMX398 sensor. "Dual-core" means that the photodiode in a pixel is divided into two, so that the separated photodiodes can receive light independently, and the phase difference formed is the "basis" for driving the motor to focus. When imaging, two independent photodiodes can be output (merged) as a pixel. Dual-core focusing is like seeing things with both eyes, while ordinary PDAF phase focusing only uses left and right eyes to see things. This means that the light input of a single focusing pixel increases by 100%, and the focusing accuracy and speed will also be improved.

Ultra-clear image quality

Ultra-clear image quality refers to a camera technology exclusively developed by OPPO, which uses multi-frame composite oversampling technology to synthesize multiple photos with CMOS effective pixel output size into an ultra-high pixel photo to obtain larger frames and more details.

OPPO Find 7 is the first smart phone equipped with ultra-clear image quality technology, which can output photos with a maximum of 50 million pixels. OPPO N3 is improved on the basis of Find7, and can output photos up to 64 million pixels. Most smartphones such as OPPO's R9s and R9s Plus can be equipped with ultra-clear image quality.

Jizhi beauty

Extreme Beauty is an exclusive software technology based on OPPO mobile phone hardware. When the user takes a selfie with the OPPO mobile phone, the OPPO mobile phone will automatically recognize the user's face, intelligently analyze the corresponding age, and give the corresponding appropriate skin care effect.

The ultimate beauty was independently developed by OPPO in 20 12. From OPPO U70 1 to create the ultimate beauty, to OPPO N3.0 to R9 series 4.0, the ultimate beauty has been updated in four versions. OPPO has always insisted on combining the best self-timer hardware with the best self-timer software to lead the trend of mobile phone self-timer.

Electric rotating camera

After OPPO N 1 introduced the rotating camera, OPPO N3 introduced the electric rotating camera again, that is, it adopted the "planetary gear three-stage transmission mechanism". With the stepping motor, the mobile phone user only needs to touch the screen, open the camera interface and gently slide the screen, and the camera will automatically rotate. Electric rotation has achieved another innovation in mobile phone photography, further leading to an innovative and interesting new photography experience.
