Shulou(Shulou.com)11/24 Report--

The most noteworthy smartphones in the first half of 2023 have basically appeared. I believe everyone can feel that this year's mobile phone market, especially the high-end mobile phone market, is still the most powerful in the image field.

I don't know when, but images have become one of the most important features of flagship phones, and sometimes you can even remove this "one."

Among the flagship images, the most interesting one is Oppo Find X6. This phone is equipped with Tianji 9200 flagship chip, and Mariana MariSilicon X forms a dual-core collaboration to provide powerful computing power for its computational photography, and has the same ultra-optical periscope telephoto as Pro. With OPPO's self-developed ultra-light image engine and Hasselblad shadow tone, it is a blockbuster at any time.

Imagiq 890 ISP, OPPO Find X6 powerful image foundation support We know that OPPO Find X6 has two killer moves on the image: telephoto photography, reconstruction of light and shadow. The former focuses on improving the zoom shooting ability of mobile phones, while the latter presents more realistic and natural photo quality by reshaping light and shadow, especially in the presentation of portrait photos.

Aside from hardware factors such as outsole sensors and lenses, OPPO Find X6 can capture clear details, natural colors, natural light and shadow, and the soul behind it is actually two words: calculation.

On OPPO Find X6, OPPO uses their most advanced image algorithm ever. On the specific architecture, first, through the ultra-clear image quality engine, the digital film (RAW data) with multi-frame original information is used for deep fusion calculation, thus bringing richer details to the picture. Then, the natural color engine is used in conjunction with the physical 13-channel spectral sensor to improve accuracy.

Finally, we analyze the correct relationship between light and shadow through the super light image engine, and restore the most real light and shadow level.

Such an advanced and complex huge algorithm architecture requires 10 times more computing power than before!

So the next key question is: Can Find X6 hardware handle such huge computing power requirements?

In Find X6, OPPO's dual-core image computing hub provides support for the three engine mass algorithms, one of which is Mariana Silicon X developed by OPPO, and the other is Imagiq 890 ISP of MediaTek Tianji 9200 platform.

We know that optical image information enters the mobile phone image path, first converted into digital information through CMOS and ADC, the most critical step is to give ISP to process the image information. In the era of computational photography, the algorithm is more and more complex, and the importance of ISP is also rising.

Imagiq 890 is an ISP that can cope with a large number of complex algorithms. Its strength lies in not only providing abundant computing power, but also closely integrating with AI. It natively supports many advanced technologies and achieves complex computational photography functions.

For example, Imagiq 890 supports intelligent image semantics technology, which can intelligently analyze the color of the environment, the structure and movement of objects, and adjust the color saturation and tone of photos with the exclusive hardware ISP layered label, so that every shot is amazing.

It is also the first ISP to support RGBW. Note that this is a dedicated support for RGBW sensors from the ISP level, which can bring 30% brightness improvement and 20% detail improvement to night photos, so that night photos of smart phones can be taken in a higher gear.

Imagiq 890 works closely with the sixth generation APU to provide a continuous stream of AI computing power for mobile phone computing photography. It adopts hybrid computing + intelligent neural network architecture. In ETHZ 5.0, a classic test to measure AI performance, its AI performance is improved by 35%, while the energy efficiency ratio in video super-sub applications is improved by more than 45%.

In short, Find X6's advanced "super light and shadow" computational photography concept can become a reality, it is the powerful computing power and leading image processing technology provided by Imagiq 890 ISP of Tianji 9200 platform that can finally present amazing photo effects in the industry. Let's take a Find X6 telephoto as an example to feel it briefly.

For example, the above scene is actually a challenge for most mobile phone photography, because the light contrast of this scene is relatively strong, and the overall light and shade level is very complex. If it was a mobile phone shot in the past, it was easy to make only the desk lamp part bright and clear, the other parts dark, or the main body clear, the light part directly overexposed, not to mention the complex tone presentation.

To take this photo well, you need to complete the complex process of multi-frame fusion, light and shadow relationship analysis and reconstruction at the moment of pressing the shutter, and process a large amount of pixel information, and the effect presented by Find X6 is undoubtedly satisfactory. The whole picture is clear and not overexposed, the text on the drink is sharp and clear, and there is a delicate transition between light and shade. Meanwhile, the overall color of the picture is also very natural and eye-pleasing.

The processing power of Imagiq 890 ISP of Tianji 9200 flagship chip can be seen.

Photographing is just an appetizer, Imagiq 890 ISP highlights OPPO Find X6's excellent video capabilities. What we said before is taking photos, but in the past two years, the image capabilities of mobile phones have long been not limited to taking photos. Video shooting is also becoming a more and more important function for consumers.

There is no need to process images in real time, so a large number of software algorithms can be involved, so there is a high degree of software customization space. In fact, the real test of ISP ability is video shooting.

Video shooting needs to be based on 30FPS / 60FPS, real-time processing of a large number of pixel data while taking into account low power consumption, so video shooting provides higher processing speed and more powerful computing power than photography.

For example, shooting video in low light requires more complex calculations to improve brightness, reduce noise, and optimize dynamic range performance, while Imagiq 890 ISP provides computing power and technical support to meet the needs of OPPO Find X6 video shooting.

On this basis, Imagiq 890 ISP also introduces a new AI Video Engine, which integrates APU + ISP hardware to provide data from camera sensors for terminal manufacturers to improve AI video enhancement, faster and more energy efficient.

For example, when shooting 8K/ 30 frames of video, Imagiq 890 ISP can achieve power savings of up to 12.5% when electronic image stabilization (EIS) is turned on, while shooting 4K / 60 frames of video, power savings of up to 11%.

Moreover, Imagiq 890 ISP can also realize the movie mode of dual-camera video recording protagonist tracking blur, front, middle and rear scene level blur, which needs real-time processing and calculation, which shows that Imagiq 890 ISP's computing power is indeed very powerful, it can support up to 320 million pixel camera, and the camera zero delay photo can support up to 108 million pixels.

Tianji 9200 and Find X6 have made mutual achievements and stabilized the high-end market together. Overall, as a standard flagship product, OPPO Find X6 surpasses the stunning image performance of the industry Pro model this time. It really cannot be separated from the support of Tianji 9200 platform Imagiq 890 ISP. It brings powerful computing power through the integration of APU and a series of leading image technology features. It laid a solid foundation for Find X6's frontier exploration in imaging.

Finally, in fact, the editor also wants to say that all this is actually the result of the mutual achievement of MediaTek and OPPO, just like Imagiq 890's powerful basic computing power and technology, but also with OPPO's self-developed focus, white balance and exposure strategy algorithm (3A), finally showing the excellent video shooting quality we see.

In fact, OPPO has always maintained a close cooperative relationship with MediaTek. This time, Tianji 9200, OPPO and MediaTek will cooperate to the deep water area. The two sides will jointly conduct in-depth joint adjustment, and carry out dual-core cooperation between OPPO self-developed image dedicated NPU MariSilicon X and Tianji 9200 chip platform, so as to jointly successfully implement the image concept of both parties.

Not long ago, DXOMARK, a well-known image evaluation agency, announced its image rating, ranking third in the global image rankings, surpassing a number of industry Pro flagship. OPPO Find X6's powerful image score has another meaning, that is, it has become the flagship of Tianji image with the highest score at present. This also lets us see once again that the Tianji mobile platform does have extraordinary and strong strength in terms of images.

In any case, under the joint efforts of MediaTek and OPPO, the image of OPPO Find X6 surpasses the industry Pro level model, and the ultimate benefit is naturally the majority of consumers.

In the future, I believe that with the innovation and efforts of terminal manufacturers such as MediaTek and OPPO, more cutting-edge technologies will be put into the hands of consumers, so that technology can truly bring us a better life.
