OPPO Takes Lead in Unveiling Innovative Technologies to the World

OPPO has been committed to technology and product innovation that creates a more comprehensive and immersive user experience. The brand is continuously working towards technological evolution from zero to one and considers technological innovation as a way to expand imagination while providing a wide range of high-end features to its consumers.

OPPO’s emphasis, technological strength and profound understanding is not only in the camera function but expands to cover all features of the smartphone. Find X2 Pro is equipped with a top-level professional display screen with a 120Hz refresh rate, 3K QHD+ and 1 billion colors. Furthermore, it is also equipped with a pioneering camera system. The screen reproduces a real and color-rich world, and the camera records it. As times change, the camera is still a frequently used function.

Of course, after years of development and competition, the Find X2 Pro wants to push the boundaries of what mobile phone cameras are capable of. This is no simple task.

Returning to the Origin to see the Path Ahead

As OPPO’s flagship for the high-end market, Find X2 Pro is expected to bring the ultimate camera experience to its users. The R&D team intended to push its shooting performance in various scenarios, including night scene, wide-angle, telephoto and video, to higher standards. Such higher standards brought unprecedented technical challenges. To find the answers they needed, our camera R&D team decided to “return to the origin”. We reviewed the development of the mobile phone camera, looked for gaps by comparing photos shot with mobile phone cameras and professional DSLR cameras, and re-examined the five underlying sensor specifications; namely photo sensitivity, dynamic range, color depth, focus performance, and signal-to-noise ratio. In the end, a new set of standards was introduced for the Find X2 Pro camera system.

• Photo sensitivity has been improved by more than 50%.
• Full well capacity increased by 50%.
• Record 12-bit color depth and directly output 12-bit RAW data.
• 100% pixel focusing capability and omni-directional phase detection.
• DSLR-level dual native ISO.

Find X2 Pro main camera adopts the 48MP pixel IMX689 module, which was developed and customized in co-operation with Sony. This sensor not only has a large size of 1/1.4 inches, but also has the largest pixel size (1.12 um) among all 48MP mobile phone camera sensors. This gives the Find X2 Pro better shooting performance in dark light, but its 1/1.43 inch size is particularly bulky for a compact phone. Thankfully, our R&D engineers managed to find a balance between performance and size.

Find X2 Pro’s cameras have adopted innovative camera technologies including all-pixel omnidirectional focus technology, a super-sensitive full-focal triple camera system, Live HDR as well as many other new technologies to make images feel even more real.

10-Bit Live HDR Video, Fully Utilizing Customized Image Sensors

Live HDR video is based on OPPO’s new pixel-level real-time progressive exposure technology. It is a new function developed in collaboration with Qualcomm and Sony that supports 4K QHD+, 30 fps, and 10-bit HDR video recording and previews, as well as a 10-bit high-dynamic display.

Structural Stacking Challenges from Large Image Sensors

OPPO R&D engineers found that the camera lens holder and the motor’s internal holder were studded with bumps. These bumps were designed to reduce the negative effects caused by impacts, but they were also the cause of the noise. Thanks to the joint efforts from our partners, our R&D team reduced the hardness of the buffer structure at the top of the Find X2 Pro’s lens holder and used silicone as the bottom buffer. When impacted, it deforms to absorb the energy and therefore reduces the noise caused.

An Unassuming Three-Microphone System Takes Video Sound Recording to the Next level

The Find X2 Pro comes with a three-microphone system. Among all Chinese mobile phone brands, OPPO is the first to implement a three-microphone design. The Find X2 Pro has 3 microphones, each of which are placed at the bottom, top and back of the mobile phone. When the user receives a call, these three microphones simultaneously perform noise reduction. In addition, their positions allow Find X2 Pro to achieve 3D recording and recording focusing when the user shoots videos.
