Good photographic calculation

OPPO is far-sighted. As early as 20 19, it was reported that OPPO began to enter the chip field, and this first self-developed chip Mariana Silicon X of OPPO met us on OPPO Find X5 Pro.

At present, people have higher and higher requirements for the image function of mobile phones. The high point is that people have new requirements for various image functions, such as moving stable snapshots, ultra-clear night vision shooting and so on. For mobile phone manufacturers, this refined demand is difficult to meet, because computing chips come from a common platform, so the user needs collected by mobile phone manufacturers may not be effectively conveyed to chip manufacturers, or chip manufacturers may not be able to make customized products according to market feedback in time for various reasons.

The flowers planted by OPPO in the early days finally bear fruit on OPPO Find X5 Pro. Through this self-developed chip Mariana MariSilicon X, OPPO has completed the vertical integration of the whole link in the field of computing images, so that algorithms, chips, sensors and general platforms can work together better. In this way, OPPO can quickly update its products and launch more competitive and popular products after receiving market feedback.

OPPO Find X5 Pro uses Sony IMX766 dual main camera sensors on the rear camera, one of which can be used as a super wide-angle lens, and the telephoto lens supports 5x optical zoom and 20x digital zoom. On the front lens, OPPO and Sony jointly customized an RGBW sensor IMX709. Whether it is front or rear, high standards of hardware are adopted.

OPPO Find X5 Pro is equipped with a new generation of Snapdragon 8 mobile platform, and Snapdragon 8 provides a better signal processor and triple ISP, which can handle more image data and information, so that OPPO Find X5 Pro can support shooting more high-definition and high-frame videos.

Snapdragon 8 is powerful in imaging system, and the previous imaging algorithm for Snapdragon is also powerful, so the all-around flagship OPPO Find X5 Pro will naturally use the Snapdragon 8 platform. OPPO's new self-developed Mariana MariSilicon X chip, based on the new gold architecture concept of DSA for the future AI era, can bring real-time AI computing energy efficiency, super HDR capability, lossless real-time RAW computing, and RGBW Pro that maximizes sensor capability through independent innovative ip design and 6nm process.

Back to the OPPO Find X5 Pro equipped with Snapdragon 8 and Marianne X, OPPO brought the first 4K ultra-clear night vision function in Find X5 Pro. With the powerful computing power of Mariana MariSilicon X and the energy efficiency ratio as high as 1 1.6TOPS/w, the resolution of ultra-clear night scene video is improved by 4 times, and the pixel-level AI noise reduction processing is realized in each frame, which removes the restriction that night scene video can only be shot at 1080P, and obtains clear video with wider dynamic range at night.

Many users will complain that when shooting a video with a mobile phone, the matching degree between the framing picture and the final output video picture is low, and the output video picture is not pure. Mariana MariSilicon X's powerful computing power also comes in handy in this regard. In the past, due to the lack of computing power of the chip, the calculated images were usually lossy processed in YUV domain, while Mariana MariSilicon X on OPPO Find X5 Pro put complex calculations in RAW domain, which made the image information of the final output video more accurate and original, and obtained higher definition and wider dynamic range than the traditional YUV domain processor, higher matching degree between the framing picture and the imaging picture, and purer video quality.

Find X5 Pro also brought another major breakthrough, adopting the industry's first hardware-level dual OIS anti-shake scheme. Through this dual OIS five-axis anti-shake scheme, the mobile phone can realize dual optical anti-shake of sensor and lens under the same lens module, and the anti-shake compensation in all directions of X axis, Y axis, pitch axis, yaw axis and roller can reduce the safety shutter to 0.5 seconds, greatly increase the light input at night, and make it easier to obtain clear and bright night proofs.

Suspension anti-shake can support 3 anti-shake and 0.7 rotation anti-shake angle at most, which makes video shooting have better anti-shake performance and can shoot stable moving pictures even in 4K ultra-high image quality. The following figure shows the comparison of video images when the dual-hold OPPO Find X5 Pro and iPhone 13 Pro pass through the speed bump.

A relatively professional mobile video player can not only make you perform video stabilization from a relatively static angle, but also achieve satisfactory performance when transporting mirrors.

Generally speaking, OPPO Find X5 Pro uses a relatively high standard sensor. Under the blessing of dual-core dual OIS anti-shake, both taking photos and shooting videos have a strong performance. The powerful self-developed Mariana X has enabled OPPO Find X5 Pro to achieve a number of major breakthroughs, and also enabled the mobile phone to obtain a top-level imaging system.
