On April 20, at the "Vivo Dual-core Imaging Technology Communication Meeting", Hu Baishan, executive vice president of Vivo, said that the self-developed chip V1+ is both a professional imaging chip and a display performance chip, as a leader of dual cores, it will bring a new standard of the second generation of dual-core flagships with a comprehensive improvement in compatibility and functionality.
The second generation of self-developed chip V1+ and the second generation of dual-core standards launched by vivo not only evolve again at the image level, but also expand the chip functions to the field of performance and display, expand support for game and video visual experience, and achieve a "core" two-purpose. So far, vivo has not only become the first terminal mobile phone manufacturer to complete the tuning with the MediaTek flagship platform on the self-developed image chip, but also the only mobile terminal manufacturer in the industry that has realized the self-developed image chip compatible with the multi-flagship platform.
Vivo self-developed chip V1+ will be 3D real-time stereoscopic night scene noise reduction, MEMC interpolation and AI super-division three algorithms for hardware packaging, with good scheduling, fast speed, high energy efficiency three characteristics, its data throughput speed can be efficiently maintained at about 8GB/s; combined with SRAM, the energy efficiency is increased by about 300%, power consumption is reduced by about 72%. In the process of in-depth joint commissioning with MediaTek, more than 30 patents were generated.
In terms of imaging, the self-developed chip V1+ continues to lead the industry as the core hardware of the algorithm. The in-depth refinement of night scene video is carried out, and the polar night video function of less than 1lux environment is realized by video noise reduction algorithm. V1+ polar night noise reduction algorithm can achieve motion prediction and compensation, combined with the chip itself high-speed, low-power extremely fast memory management system, with the camera module, main chip and vivo self-developed algorithm to improve, so that the mobile phone has reached the imaging level of professional night vision.
Vivo V1+ has also brought real changes to users in terms of image experience.
The first is color. Vivo proposed the "vivo memory color system": vivid, bright and textured vivo vivid colors, as well as the pursuit of faithful restoration of human eye vision, the pursuit of the ultimate color performance of ZEISS natural color, from the detection, shooting, processing, display of the four dimensions to carry out full-link color management.
On the display device side, Vivo first developed its own XDR Photo technology, which realizes the ultra-high dynamic range display of photos, and the brightness of the highlighted area of the photo can be increased by up to 350%, and the look and feel is brighter and more transparent, giving users a more immersive experience.
In the shooting session, vivo V1+ increased the ΔE of ZEISS natural colors by about 8.3% on the basis of about 15.5% compared with the past, and made the tone of ZEISS real colors more excellent through fine tone.
The second is the portrait. Vivo makes technological breakthroughs before, during and after portrait shooting: helps users cope with complex and diverse portrait scenes by calibrating and adapting; launches the ZEISS portrait lens package, which provides a variety of classic portrait bokeh styles; and obtains professional texture portrait works through the portrait algorithm matrix.
According to reports, as the flagship platform of MediaTek, Tianji 9000 has received widespread attention from the market with its excellent performance and excellent energy efficiency since its release. As strategic technology partners, Vivo and MediaTek have invested in an elite development team of more than 300 people since last year, and after 350 days of in-depth collaborative development of software and hardware, the V1+ chip and the Tianji 9000 are adjusted and adjusted, releasing the strongest performance of the Tianji 9000.
In order to improve the energy efficiency ratio of the Tianji 9000 platform, Vivo uses the algorithm to adjust the CPU resource allocation strategy to reduce heat generation, and solves the problem of performance probability fluctuation after several iterative tests, effectively improving the energy efficiency ratio of the Tianji 9000 platform. The test results show that in the game scenario of high performance requirements, the Tianji 9000 can extend the battery life of the game by 10%.
Hu Baishan said that in the past 10 years, vivo has insisted on in-depth research and development, polished details, and made efforts in places that cannot be seen, just to always bring users the experience of "super cup", which will also be reflected in the upcoming vivo new generation flagship model - X80 series. In the future, vivo will also use up to 5 to 6 years of technical pre-research, in the direction of its own setting, according to its own rhythm, out of a path belonging to vivo.
