Everyone pays different attention to mobile phones, such as appearance, screen, performance, battery life, etc., and imaging capability is an important criterion for my purchase. When it is inconvenient to use the camera to take pictures, the mobile phone is a powerful tool. On the basis of inheriting the excellent images of the previous generation OPPO Find series, OPPO Find X5 Pro has raised the imaging capabilities of the OPPO Find series to a new peak through the self-developed Mariana X imaging dedicated NPU, and also opened a new journey of domestic self-developed core imaging.
Mariana X is OPPO’s first self-developed image-specific NPU, providing more powerful computing power support and a very high energy efficiency ratio. The more advanced the manufacturing process, the more difficult the design is, not to mention the Mariana X that started from 0. According to an interview with Jiang Bo, senior director of OPPO chip products by “One Watch”, the OPPO chip team has made unremitting efforts to successfully tap out the first self-developed 6nm process chip. Since Mariana X is a self-developed chip, the original 3A algorithm (AE automatic exposure, AWB automatic white balance, AF automatic focus) that comes with the Qualcomm platform is no longer applicable, and the relevant code needs to be completely rewritten. Everything starts from 0, which can be said to be the most adventurous image attempt of OPPO.
The birth of Mariana X is not only the first successful challenge of the 6nm process of domestic self-developed chips but also brings a substantial upgrade to OPPO’s image data processing. The computing power of Mariana X is as high as 18TOPs, surpassing the 15.8TOPs of the 5nmA15 chip on Apple’s iPhone 13 Pro Max in one fell swoop, which is eye-catching. The energy efficiency of 11.6TOPs/w allows Mariana X to process the same amount of data with less power consumption, saving the power of mobile phones.
The powerful computing power and energy efficiency ratio of Mariana X has enabled OPPO Find X5 Pro to usher in an unprecedented 4Knight scene HDR video era. Combined with pixel-level AI noise reduction, the ultra-clear image quality of night video can be achieved.
It turns out that the dynamic range that is only available during the day, the night scene mode of OPPO Find X5 Pro can also have it. Mariana X makes the dynamic range of the picture reach an astonishing 20bit, and the signal-to-noise ratio is as high as 120db, which is 4 times higher than the previous generation OPPO FindX series. I tried to shoot a 4K night scene HDR video, the picture is very real and moving, the lights of thousands of houses, the bright night has a panoramic view, the details of highlights and shadows are also well preserved, and the look is real and natural.
Limited by the lack of computing power of mobile phone chips, traditional image data calculation is lossy processing in the YUV domain. Mobile phones generally choose to set noise reduction modules in the RAW domain, RGB domain, and YUV domain to control noise (picture noise), and after the image data is processed layer by layer, the nature of the noise becomes more complex and difficult to handle.
The data processing of the original image by Mariana X outputs high-quality data after lossless calculation for the entire image link, bringing about the improvement of basic image quality, preview imaging, and the image quality of third-party apps. Therefore, when you use a third-party APP to take pictures, you can take pictures as clear as the system camera, especially when using WeChat, the “slag” picture quality taken with the built-in camera has become a thing of the past.
Let’s take a look at the detailed parameters of the imaging hardware of OPPO Find X5 Pro:
OPPO Find X5 Pro follows the flagship dual main camera solution, and its rear image module sensor is also the same as the previous generation. As we all know, the sensor of a mobile phone needs to be polished and optimized for many generations in order to fully squeeze its performance potential. Combined with efficient algorithms, the mobile phone has better imaging performance.
Let’s first look at the ultra-wide-angle camera of OPPO Find X5 Pro. Its sensor is a 1/1.56-inch Sony IMX766, which supports up to 50-megapixel still image capture. The lens has an equivalent focal length of 15mm (0.6x) and an aperture of F2.2. Lens design. The addition of free-form surface lenses gives OPPO Find X5 Pro ultra-wide-angle strong distortion control. When shooting scenes with more regular lines such as urban buildings, there are basically no lines that are greatly bent due to lens distortion.
The following are ultra-wide-angle proofs:
The main wide-angle lens of the OPPO Find X5 Pro is equipped with the same IMX766 sensor as the ultra-wide-angle camera. The lens has an equivalent focal length of 25mm (1x) and uses a “1G+6P” luxury lens optical module. Among the 7 lenses of the main camera, there is a customized glass lens, which reduces the chromatic aberration of the main camera lens by up to 77.39% compared with the pure resin lens camera, which ensures the accurate color of the picture and improves the image quality and clarity at the edge of the picture. Of course, the cost has also increased accordingly.
On the main camera of OPPO Find X5 Pro, sensor anti-shake and lens anti-shake on high-end mirrorless cameras are also added, so that the main camera sensor can offset hand movements in all directions and work in conjunction with the optical anti-shake supported by the lens. , forming a suspension anti-shake system, which greatly enhances the stability of the mobile phone when shooting. According to the relevant data provided by OPPO, the suspension anti-shake system can achieve a safety shutter of 0.5 seconds, increase the amount of light entering on a stable basis, and greatly improve the quality of night scene photos.
Stabilization is enhanced, and video capture benefits as a result. Usually, we want to use a mobile phone to shoot a stable video, and it needs to be matched with a mobile phone stabilizer to obtain a more stable and smooth effect. If you shoot directly by hand, the difficulty will be increased accordingly. I used OPPOFindX5Pro to shoot a video, even if I run or even shake the phone, the picture of OPPOFindX5Pro is still relatively stable. Suspension anti-shake supports up to ±3° anti-shake and ±0.7° rotation anti-shake angle, reducing the picture difference between adjacent single frames, and better serving the multi-frame synthesis algorithm.
The ICE2.0 dynamic capture engine is also developed based on the newly added suspension anti-shake system. It first recognizes multiple raw materials automatically shot by the mobile phone through AI scenes, selects clear parts for synthesis, and then performs optimization processing to improve image purity. Reduce noise. Therefore, for sudden moments, OPPO Find X5 Pro will not miss it.
The following is a sample of the wide-angle main camera:
The rear image module of OPPO Find X5 Pro also has a telephoto lens, and its sensor is Samsung S5K3M5, with a 13-megapixel design. The aperture of the lens is F2.4, and the lens group is composed of 6-piece lenses, with a viewing angle equivalent to 50mm (2x) focal length, which is closer to the focus area of the human eye.
OPPO Find X5 has three rear lenses, the zoom transition is delicate, and the director’s cut is also very fast, bringing you a comfortable viewing angle change experience.
The 10-bit shooting capability of the previous generation OPPO Find X series has also been retained. In the camera settings, click the 1 billion color image switch to enable the OPPO Find X5 Pro to have the shooting capability of 10-bit images. Combined with the rear spectral sensor and self-developed algorithm, it can perceive more Real light source information. When encountering a large area of pure color space or complex color scenes, it can also improve the white balance effect of the picture very well.
On the OPPO Reno7 series, the exclusive customized super-sensitive sensor IMX709 is highly praised by selfie experts. Because it adopts a forward-looking RGBW pixel arrangement, which replaces a green pixel with a white pixel, the light perception capability of the sensor is enhanced. Compared with the traditional RGGB sensor, it has a stronger low-light performance, making OPPO Find X5 Pro the current front-end The most powerful flagship phone for low-light shooting.
OPPO’s “traditional artistic ability” – portrait beauty, affects the hearts of young ladies and sisters. OPPO Find X5 Pro’s natural fairness, transparent and generous beautifying effect makes the young ladies and sisters who have used it love it. At the same time, its front-facing camera supports switching between two viewing angles, allowing one-person Selfie and multi-person Selfie to be mastered freely.
On the back of the OPPO Find X5 Pro, the exquisite Hasselblad words are very eye-catching, which is also a sign of the strategic cooperation between OPPO and Hasselblad. After the extremely difficult sensor-level color calibration, users can feel the ultimate color performance.
In the camera, you can call up the Hasselblad professional mode, adjust the shutter speed, sensitivity, exposure, etc. flexibly, switch the lens angle flexibly, and have a histogram to assist the picture reference, press the Hasselblad-flavored orange shutter button, listen to lifelike The Hasselblad shutter sound will make you feel happy.
At the same time, OPPO has also teamed up with Hasselblad ambassadors from different countries to carefully modulate three master filters, and use specific filters to shoot in the suggested scenes, and the texture of the blockbuster is easily captured. Especially in the shooting interface, the optical viewfinder of the Hasselblad XPAN camera is reproduced, and it can switch between two styles of color and black and white. The 65:24 wide angle of view has its own cinematic attributes, and it is matched with the classic equivalent of 45mm. The lens is as full of ritual as using a film camera.
Mariana X (MariSiliconX) was launched at OPPO INNODAY 2021. It is an image-specific NPU, and it is also OPPO’s first self-developed chip, which was first released on OPPO Find X5 Pro. Some friends will ask, the SoC of the mobile phone already has the relevant data processing capabilities, why should we develop an image-specific NPU (Neural Network Processor)? Because the processing power of SoC-related components alone cannot meet the growing demand for computational photography.
The purpose of the NPU is not to replace the related components, but to supplement the computing power of the chip platform, and the related components become the “left and right brain” of image data processing. Improve the imaging quality of the device through AI learning and training, and enhance the shooting experience of custom sensors and third-party imaging apps.
OPPO Find X5 Pro is not only a “muscle show” move by OPPO in the industry, but also an important milestone for domestic self-developed cores. The addition of high-standard sensors, improved anti-shake components, and glass lenses has strengthened the position of the OPPO FindX series of imaging flagships. The strategic cooperation with Hasselblad brings accurate, natural colors and a delicate and ceremonial shooting experience. If you love taking pictures, you may not be able to refuse.
OPPO founder and CEO Chen Mingyong’s statement on OPPOINNODAY2021: “Technology companies must solve key problems through key technologies. If there is no underlying core technology, it is impossible to have a future. And flagship products without underlying core technology are castles in the air. “. The road to self-development of domestic chips is not smooth sailing. It is precise because there are many technology companies that are as down-to-earth as OPPO and are not afraid of difficulties, the technology of China’s high-end manufacturing continues to improve, and the future of China’s high-end creation is infinite.
