On July 27, according to Tencent’s “Deep Web” report, OPPO and vivo will soon release self-developed ISP chips (image signal processors).
According to reports, OPPO’s chip project team has reached thousands of people, and the ISP used in the field of mobile phone imaging will first be applied to the OPPO Find X4 series of mobile phones that will be launched early next year.
Vivo insiders said that Vivo established a self-developed chip team two years ago.There are about five or six hundred people in the team, and there is a project called “Yueying”. The first product to locate the image direction will be used on the X70 series mobile phones to be released in the second half of the year.
Prior to this, Xiaomi had also launched a self-developed ISP chip-Surging C1, which is independent of the motherboard and used in Xiaomi’s first folding screen mobile phone, MIX FOLD.
It is reported that ISP (Image Signal Processor, graphics signal processor), is mainly responsible for processing the image part of the work, to a large extent directly affects the image quality, is a very important part of the mobile phone system.
According to Xiaomi’s official introduction, its ISP chip can provide more refined triple A processing, specifically:
AF: Faster and more precise AF focusing performance, greatly improving the ability to focus on dark light, small objects and flat areas.
AWB: A more refined AWB white balance algorithm, accurate reproduction of complex environmental light sources.
AE: more accurate AE exposure strategy, better night scene and dynamic scene performance
It is worth mentioning that,Most of the ISP modules used by smartphones are integrated on Soc, so that mobile phone manufacturers do not have much initiative to adjust the parameters and algorithms of the ISP module to perfectly fit their own products. As a result, various manufacturers have begun to develop ISP chips independent of Soc. .
Xiaomi told Leifeng.com (public account: Leifeng.com) that Xiaomi’s ISP chip was planned and approved in 2019. It took more than two years and invested hundreds of millions of yuan in research and development, and finally it will be commercialized in 2021.
For the optimization of the ISP chip, Xiaomi focused on improving the basic experience, performance algorithms, and functional differentiation. Xiaomi said that Xiaomi has completed the 3 to 5 year plan for the camera chip and hopes to maintain continuous product differentiation and competitiveness through continuous iteration.
Of course, not only Xiaomi OV, as early as 2015, Huawei integrated a self-developed ISP module on HiSilicon Kirin 950. Samsung and Apple, which also have independent chip design capabilities, have also been using self-developed ISP chips.
Whether it is from a demand perspective or an industry perspective, it is the general trend for major manufacturers to launch self-developed ISPs. It is not only a feedback to consumers’ advanced shooting needs, but also a requirement for their own hard power technology.
It is undeniable that ISP may be an important change factor in order to differentiate in the homogenized Android smartphone market. Compared with mobile processors, ISP chips are less difficult, but their role in smart phones cannot be ignored.
However, for domestic mobile phone manufacturers, the ISP chip is only the beginning of the core layout, the final completion of the board, or the self-developed SoC.
In fact, Xiaomi released its first self-developed Soc Surging S1 in 2017. Although the follow-up series did not follow up, the release of the Surging C1 this year also allowed the public to see the hope of Xiaomi making cores again.
in addition,OPPO also has plans to develop Soc on its own. As early as 2019, OPPO acquired 58 Intel’s cellular mobile communications core technology patents, and also acquired over 500 Ericsson patents. Now the chip team has been exploded to thousands of people.
From the outside, OPPO’s goal is not limited to a small ISP.
Starting from the ISP chip and then to the SoC, this is a step by step process, so I can’t rush. It will take time to verify whether ISP is expected to further promote the autonomy of domestic chips in the future.
Let the bullet fly for a while.
