I livealways attentive to the imaging sector of its devices, announced two new imaging strategies for an even better user experience. In the field of technical innovation of optics, computing power and algorithms, vivo has officially announced the Video Imaging Technology Matrix: a technological matrix that sets a new standard for the imaging capabilities of products making them even more competitive at a professional level.
Focused on three key features and based on two strategic pillars of joint and independent innovation, this new matrix was designed with the dual objective of creating a competitive advantage in an increasingly uniform market such as that of imaging and to create a technological singularity in the field of mobile imaging.
What is vivo Imaging Technology Matrix
In order to compete with professional devices, vivo has created some powerful imaging technology modules, including Optical Sensing System, Color Restoration Engine And Accelerated Computing Enginewhich allow smartphones to efficiently record and process information about color, tone and image quality, from the moment the light is captured until it is shot, just like professional equipment.
Also, the environmental perception technology di vivo allows users to perceive their surroundings through the eyes of professional photographers, allowing them to recognize the color temperature of the scene, the lighting and other useful information that allow them to automatically visualize the best way to capture images. With the support of VCS Bionic Spectrum technologywhich ensures better control of image noise and color rendering, new generation sensor improves signal-to-noise ratio by 20% and color rendering by 15%compared to the previous generation IMX866 sensor.
To better handle portraits and night scenes, vivo has introduced Hyper-Sense Portrait System And Vast-Sky Night System which allow semantic extraction and even more precise optimization, significantly improving the expressiveness of the photo.
Hyper-Sense Portrait System provides the user with a complete set of solutions for portrait photography which, thanks to the algorithm developed by vivo, perceives the characteristics of the portrait, optimizes the details of the subject at the micron level and creates a unique atmosphere. The new Vast-Sky Night Systembased on vivo’s self-developed AI algorithm and enhanced optical sensor, is instead capable of optimize photographic sensitivity by 100%with ISO up to 102400. This makes it possible, for example, to take long exposure photos of a starry night sky, which previously had to be done with a tripod or stabilizer, but can now be done easily with a smartphone.
Innovation “made by vivo”: the new generation custom chipset
At the hardware level, alive presented the latest generation custom imaging chipset. To cope with the more complex application scenarios of smartphone multi-camera systems, the new generation of custom chipset imaging will use AI-ISP architecture, bringing the low latency and high efficiency of traditional ISP to time processing AI architecture real. The innovative 10-bit MAC circuit is customized to efficiently perform 10-bit operations, reducing inference latency by up to 96% compared to traditional NPUs and improving power efficiency by up to 200%.
Based on the innovative AI-ISP architecture, vivo’s next-generation custom chipset includes three updates customized units that allow you to achieve revolutionary results. First of all, the upgrade of the on-chip memory unit which makes it possible to reach a data transmission speed of 1.3 trillion bits per second and guarantees extraordinary computing power. The upgrade of the AI computing unit on the other hand, it allows to achieve an ultra-high and unprecedented energy efficiency ratio. Not only that, the DLA peak energy efficiency ratio reaches 16.3 trillion operations per watt and thus establishes a new frontier of computing power in the industry. In the end, the image processing unit has been upgraded to enhance the effects of AI-NR noise reduction algorithms, HDR tone blending, and MEMC frame interpolation, allowing users a better photo capturing experience. Finally, vivo presented the next CMOS sensor larger proprietary size designed for next generation products, with 77% higher light sensitivity capability than NGV.
Multi-scenario applications of imaging technology to enhance professional creativity
To provide advanced professional imaging capabilities for everyone to enjoy, vivo has worked with users’ core photographic needs in mind and, in particular, the development of its technology in the three most interesting usage scenariosi.e. shots of landscapes, portraits and videos. The performance of vivo smartphones in terms of color, tone and image quality are three important aspects, and to enhance the capability of these three functions, vivo has built the path “real world – imaging system – post-processing algorithm” along the matrix of imaging technology, relying on environment perception technology and Color Restoration Engine.
In the shot of a portrait it is important to consider three aspects: identification, embellishment and atmosphere. On this format, vivo’s portrait processing technology works by making the skin look more natural, maintaining the sense of three-dimensionality of the five senses, processing the integration of people and the environment in terms of tone, color, brightness and blur to achieve a harmonious and natural effect of people and scenes.
As for the technology of video capture, vivo simplified LOG mode and complex color mixing process in post-production, also developed HDR standard video recording and display with dynamic metadata, supporting wider BT.2020 color space, color depth of 10 bits and 1.07 billion colors. In this way, vivo is able to better render the light and dark atmosphere of a place or scene with a variety of cinematic 3D LUT color styles, so that users can create a cinematic experience with just one click. click.
Joint innovation: the global partnership with ZEISS for mobile imaging
The new imaging technology matrix was built with the expertise that vivo has acquired over time. In 2020, vivo and ZEISS entered into a global imaging partnership, and based on the cooperation in the field of optical imaging technology, the two partners will further develop optical quality standards for mobile imaging in the future and explore the miniaturization of the camera module.
This collaboration aims to create more exciting mobile imaging experiences and take the performance of smartphone photography to the next level.
The imaging system co-engineered by vivo and ZEISS, the customized algorithm and chipset, and the further upgrades of the software and hardware system, have greatly improved the performance of color, tone and image quality, offering users realistic, full, vivid and dynamic images, whether they are landscape photos, portraits or videos. In the future, vivo will continue on this path to continue offering innovative technologies in the field of mobile imaging.
