After the press conference ,OPPO Find Li Jie, President of product line OPPO Find X5 Series product manager chenqiong accepted TechWeb An exclusive interview with a reporter , Just OPPO Find X5 Series WIP design 、 market positioning 、 The function performance is explained in detail .

About Mariana MariSilicon X First show

Find X5 Pro carrying OPPO The first self-developed image dedicated NPU chip —— Mariana MariSilicon X, adopt DSA New golden architecture concept 、6nm Advanced process and self-developed IP Design , Bring customized integration of image vertical links , Break the algorithm 、 The long-standing problem of cooperation between chip and sensor , Lift computational photography to a new height .

Through self-study, Mariana MariSilicon X Up to 18TOPS Computational power and up to 11.6TOPS/w Energy efficiency ratio 、20bit Ultra HDR Dynamic range capability 、20bit RAW Domain processing 、RGBW Pro Performance of dual channel processing ,Find X5 Pro Support four chip level image experiences for the first time ：

Chip level 4K Night view video , Greatly improve the dark details of the video during night shooting 、 Highlight suppression and color restoration , Make every frame of the night scene video can be a super clear night scene photo ; Chip level HDR video , In particular, the depth of integration of custom sensors IMX709 RGBW Pixel arrangement , Bring closer to the real dynamic range performance for front shooting ; Chip level 4K Polar night video ： In an environment with almost no light ,Find X5 Pro Still be able to capture the video picture with retained color ; Chip level App Camera enhancement ： The addition of self-developed chips makes Find X5 Pro For the first time, it can improve the underlying video streaming picture of Android camera , Through the calculation of the original data , Can help wechat 、 Tiktok 、 Kwai, etc App Your camera gets a purer and clearer picture .

Talking about Mariana MariSilicon X, Li Jie said ,1、 Mariana is not ISP, Conventional ISP It deals with a simple multi frame synthesis algorithm , But for deep learning and AI Algorithm model , It's actually more difficult . Mariana X Is a NPU,AI Computing power is stronger than traditional ISP, There are independent NPU modular , We can AI Algorithm placed in RAW Domain .2、 About the cooperation relationship or division of labor between Mariana chips and Qualcomm ： Go back to the image processing link , In the overall link , Mariana is placed on the snapdragon ISP Before , from sensor Coming out RAW The data is processed by Mariana , Next ISP The relay , adopt RAW、RGB、YUV A series of processing . So Mariana X The data volume is the most primitive 、 The largest RAW Process and maximize the value of domain data , such as AI Noise reduction 、HDR etc. .3、 Mariana X It also undertook self research for the first time 3A The output of the algorithm .3A The algorithm is the role of the headquarters in the video link , Lead the focus 、 Exposure 、 White balance and so on , So Mariana X To coordinate the lens 、 Natural color sensor , And the following Xiaolong ISP To deal with .

Li Jie predicted that , One machine with two cores will exist for many years in the future . In the next two or three years , Even later ,OPPO Will follow this line of thinking , And will gradually go below the low-end models , Even if the low-end model is separated from the main chip capability , It can also reach the flagship level in some scenes .

About suspension anti shake

Find X5 Pro Equipped with industry-leading suspension anti shake , The first mock exam on the same module on mobile phone. + Dual optical anti shake of sensor , The safe shutter time can be increased to 0.5s, Greatly increase the light input , Make the picture quality of night view photos clearer and brighter . Suspension anti shake increases the anti shake amplitude 3 times , The highest support ±3 And anti shake ±0.7 Degree rotation anti shake angle , Compensate for the jitter caused by each motion track during video shooting , Stable video quality .Find X5 Pro Equipped with the second generation self-developed ICE Dynamic capture engine , It can be adjusted for the scene in the shooting picture AI distinguish , And select the clearest part of the multi frame material for synthesis , Even in high-speed motion scenes, you can easily capture a clear picture .

Chenqiongyu thinks . Compared with the traditional anti shake Technology ,OPPO There are great differences in the structure of suspension anti shake , At present, the mainstream of the industry is single OIS, Suspension anti shake is a combination of two sensor displacement anti shake and lens optical anti shake . The mainstream anti shake technology in the industry is mainly the two axes made on the lens OIS.OPPO The suspension anti shake has lateral displacement 、 Longitudinal displacement and rotation , Pack the three-axis motion , So as to compensate more axes , Form a complete suspension anti shake system , The whole brings about the original 3 Times the improvement of anti shake performance , The stable exposure time has never been longer OIS Of 1/30 Seconds increase to 1/2 second . The second is the difference in performance .

About Tianji 9000

Find X5 Series include Find X5 Pro,Find X5 as well as Find X5 Pro Tianji Edition . among Find X5 Pro Tianji Edition , The world's first Tianji 9000 The flagship 5G The mobile platform , Deliver maximum performance while , Achieve more balanced power performance . Tianji 9000 Take the lead in adopting TSMC 4nm Process technology , Adopt a new generation Armv9 framework , Adopted 1+3+4 The three cluster flagship architecture provides powerful computing performance . The fifth generation of high energy efficiency APU 590 Compared with the previous generation, the performance and energy efficiency are improved 4 times , Give Way Find X5 Pro Of APU The benchmark exceeds the PPM mark . Besides , New and upgraded 18 position HDR-ISP Image signal processor Imagiq 790, coordination Find X5 Pro Tianji version 10 100 million color double main camera , Achieve outstanding shooting results .

However , Tianji 9000 Version of Find X5 Pro There are also trade-offs . Talking about why Tianji version Find X5 Pro Mariana... Is not used X The problem with chips is , Li Jie explained , Mariana X stay Find X5 Pro The workload of training is very heavy , The workload is exponential . Because it needs to debug the underlying basic algorithm , It is equivalent to that this generation of products has done the development work of the normal three generations of products . The design concept of suspension and anti shake is the same as that of the previous OIS Anti shake is different , The whole project is also very large . Secondly, Tianji 9000 Chip mass production time , Bixiao Dragon 8 A lot later , The whole R & D progress is totally impossible cover, So we were forced to sacrifice Tianji 9000 Suspension anti shake and self-developed Mariana X.

About Find The present and future of the series

OPPO Find The series makes OPPO Have a firm foothold in the high-end field , Looking back , Looking forward to the future , Li Jie concluded that , Now? Find Series of products , It's much denser than before 、 A lot more , The idea behind this is , We are trying our best to go high-end . If you see various market data, you will find , The market is going down , But the high end is going up . in other words , Where is the market , Where is the user , Where should we go , This is a dimension .

The second dimension , Three or four years ago Tony That is to say, it is necessary to truly transform into a deep-water R & D product enterprise , We found that some good things we had invested in were slowly coming out , This process requires product hosting . If you don't use many technologies for a year or two , We also have the experience of failure , Like folding light change , But once there is no application later , It's not just technology , The market will not remember that this technology is yours . So we put in some in-depth technology before , There will be many flagship products . I also have no way to answer whether it is carried out at a fixed pace , But it must be rhythmic , And will iterate over the product more steadily than before .
