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

On November 16, the 2023 OPPO developer Conference (hereinafter referred to as ODC23) with the theme of "Innovation and shared Wisdom" was held at the Shanghai World Expo Center. The reporter learned at the ColorOS capability sub-forum that OPPO announced that it will open its core video capabilities based on the Android standard interface Camera Extension, and launch new Link Boost 5.0, physical light engine 2.0 and ADP adaptive performance capabilities. Communication and mobile game performance optimization will help developers improve the application service experience. At the same time, OPPO released the end-side AI panorama for the first time, building three capacity units to promote the evolution of AI capabilities, and join hands with developers to explore the user experience from intelligence to wisdom!

The open system of image ability has been upgraded, and the tripartite camera can also take large films with texture.

In the past, it is difficult for the three-party camera to achieve the high image quality of the system camera. In the face of the increasing image quality needs of users, developers can only invest more cost to adapt to the interfaces of different manufacturers. Now OPPO has announced that it will upgrade its existing CameraUnit open engine to the Android standard interface Camera Extension. "through the Android standard interface, developers can effectively reduce the access cost of applications," said Tian Zhijian, senior video product manager at OPPO. "this will greatly increase the willingness of developers to access, thus bringing users closer to the effect of the system camera."

At the same time, OPPO will also open the MultiCamera interface, so that developers can call all the cameras of the phone, so that the three cameras have the same seamless zoom ability of the system cameras, while the opening of the underlying HDR and noise reduction algorithm can significantly improve the image quality performance of the three cameras in high dynamic and dark scenes. In addition, OPPO also unreservedly opened up the portrait virtual algorithm, so that the tripartite camera's main body matting is more accurate, the background is more natural, and one shot is a high-quality portrait blockbuster.

With better shooting ability, the display effect must also be arranged, which is the latest global color management of OPPO. It can solve the problem of inconsistent color display of photos in different applications and help developers achieve correct color management; at the same time, OPPO also actively embraces Google's UltraHDR standard and is compatible with UltraHDR standard in the upgrade of ProXDR program, further promoting the ecological maturity of HDR photo display, so that three-party applications can also show the same HDR display effect with highlight details.

The end-side AI panorama was released for the first time, and four AIGC applications were initially landed.

At the beginning of the year, the hot circle of ChatGPT and the continuous landing of AIGC technology scenes such as Miao Duck camera and Microsoft Copilot mean that AI has opened a broader space for mobile phone intelligent experience and exploration, for which OPPO has always maintained technical exploration and capability reserves, and officially announced the OPPO ColorOS end-to-side AI panorama on ODC23. According to Yuan Lunxi, head of OPPO software intelligence and capability development, OPPO will start from the three capability units of intelligent creation, intelligent office, and perceptual decision-making, and will continue to invest R & D resources to promote the evolution of AI capabilities through machine learning, deep learning, ColorOS end-to-side large models and other algorithms and end-to-side AI infrastructure construction.

At present, OPPO has completed the deployment of end-to-side capabilities such as textual graph generation, and brings users the functions of flash matting, magic editing-passerby elimination, call transcripts, computer assistant and so on, so that users can feel the convenience brought by AI at the end-side. At the same time, OPPO also welcomes more developers to join hands to explore the landing of AI achievements. For this reason, OPPO will help developers access at low cost through complete platform construction, optimization of access process, algorithm access tooling and other measures.

More than a thousand 5G patents promote the upgrading of three major communication technologies and enhance the smooth network experience.

Liu Shu, senior software product manager of OPPO, said in the live sharing that OPPO has more than 2800 5G standard patents and more than 9000 3GPP standard manuscripts, and its solid communication capability base brings a new Link Boost 5.0 to developers. The communication sharing feature allows nearby Pad and other devices to make calls and surf the Internet with the communication capability of mobile phones; intelligent cloud acceleration reduces the number of games with high latency by 99.43% in a weak network environment; and Dual PS supports three-party applications to use two different SIM card networks on one or more devices at the same time, allowing dual-channel data transmission, doubling the transmission speed and greatly enhancing the network experience of the three-party applications.

Physical light engine 2.0, ADP adaptive performance ability to create realistic and smooth game effect

With the user's expectation of picture quality and fluency gradually similar to that of PC games, there are higher requirements for manufacturers' mobile graphics rendering capabilities and breaking the differences in the game running environment to achieve a consistent and smooth experience. OPPO's latest object light engine 2.0 further optimizes transparent body refraction and specular reflection, adding path tracking rendering function to produce higher-order light tracing effects; and OPPO is actively optimizing ray tracing noise reduction technology to achieve softer and more detailed shadow effects. For global lighting, OPPO mobile graphics engine-based open source O3DE, game super score and other cutting-edge technology areas, OPPO senior systems engineer Wen Yuyou also said: "OPPO is increasing technology investment to land as soon as possible, empowering developers to bring more amazing game results for users."

Yi Wenyuan, senior technical planning manager of OPPO, and Chen Xinfu, chief architect of game technology, conducted in-depth analysis and discussion with Unity engine experts on mobile game experience problems such as stutter frame drop, performance degradation, hot hands and so on. OPPO and Unity, a widely used real-time content development platform around the world, jointly provided practical solutions, and also cooperated with Arena of Valor and other national games to adjust the performance of adaptive picture quality. By decomposing and tuning the underlying technology, OPPO breaks through the traditional way of performance cooperation and works with developers to bring players a smooth and high-quality experience of games on mobile devices.

Knowing developers' concerns and solving developers' difficulties, OPPO's in-depth ability to improve image, communication and game performance will help developers to further reduce development costs and enhance application service experience. At the same time, we can also see that OPPO is constantly exploring cutting-edge technologies such as AI, working with developers to open up the unlimited imagination of mobile intelligent experience!
