[Mobile China News] The vivo X80 series, which has recently continued to sell well, has won unanimous recognition from professional media and netizens for its excellent performance in all aspects of imagery and performance. Among them, the low-light mobile phone "night vision" is particularly eye-catching, it needs not only a certain ability, but the coordination, integration of various capabilities, mutual support. In the vivo X80 series, through the mutual support of lenses, calculations, algorithms, and chips, under the improvement of full-link technology, the low-light mobile phone "night vision" was finally created.

Self-developed chip V1+ hardware-level computational photography leader
The V1+ chip equipped with the full model of vivo X80 series can support real-time black light night vision function, allowing users to see a clearer and brighter real-time preview in the polar night environment. In the X80 series, the main chip is responsible for routine shooting work, and in the application scenarios of high-intensity computational photography such as night scene video shooting, the self-developed chip V1+ will be responsible for brightening noise reduction and real-time preview.
The V1+ chip will consume the most expensive and most performance-hungry algorithms, and hardware package them into their own platforms. Hardware-level algorithm packaging can ensure that the operation is targeted and maximizes its own performance. V1+ finally encapsulates three of the most complex algorithms in mobile imaging, namely 3D real-time stereoscopic night scene noise reduction, MEMC interpolation and AI superdivision. Great hardware efficiency is achieved in cooperation with the main SoC, data throughput speeds can be efficiently maintained at about 8GB/s, energy efficiency is increased by about 300%, and power consumption is reduced by about 72%.
Relying on V1+ powerful polar night video noise reduction algorithm, fast speed, low power consumption of the extreme speed memory management system, as well as camera module, main chip, vivo self-developed algorithm improvement and other aspects of the cooperation, and finally realize the polar night video function in a less than 1lux environment.
Integrated two-core synergy The deepest SoC joint commissioning
The addition of the self-developed chip V1+ has enabled the vivo X80 series to obtain the pattern of "one-piece dual core", which also makes the collaborative interaction between the main chip SoC and the self-developed image chip more possible. In order to complete the effect of the "night vision" of the low-light mobile phone, Vivo and chip manufacturers have carried out close collaboration and joint innovation beyond the industry's norms.
Taking MediaTek Tianji 9000 as an example, this chip itself has strong basic performance and AI special processing capabilities. Combined with these characteristics, Vivo and MediaTek carried out in-depth cooperation, and finally made the V1+ chip and Tianji 9000 reach a close image synergy.
Vivo and MediaTek have carried out multi-level joint polishing from the underlying hardware to the software. Behind a night shot, the image enters the ISP by the flagship super-large main camera; followed by the Tianji 9000 Tianji 5G open architecture to drive the processing of the image, providing efficient AI quality computing while ensuring reduced bandwidth power consumption and picture delay; next is the algorithm layer, Vivo's unique unique AI noise reduction algorithm begins to work to complete the processing of the night scene; and supporting this large number of AI calculations is the fifth generation APU 590 of the Tianji 9000, which can achieve AI Edge deployment neural architecture search technology, NeuroPilot model deep hardware fusion, A8W8 hybrid A16W8 HD parsing operator, and finally make complex HD video algorithm real-time processing feasible, while minimizing energy consumption.
This kind of close cooperation between you and me, I have you, let the two chips perform their duties, reduce the waste of performance and power consumption while ensuring the night vision effect of the whole link, and release the technical synergy advantage.
A night scene, using a multi-dimensional night scene algorithm
In terms of algorithms, vivo X80 series has upgraded a more advanced night scene algorithm. For example, the Super Night Scene RAWHDR3.0 algorithm can move the Super Night Scene Algorithm from the YUV domain to the RAW domain to obtain better brightness and shadow tone performance, so as to make the night scene processing process more reasonable and the color adjustment under the night color more detailed. For example, vivo's SuperRAW integrates the self-developed RAWHDR multi-frame algorithm, whether it is a large light ratio backlit scene or a night scene, it can dynamically capture up to 10 frames of images in the RAW domain for ultra-high fusion and noise reduction processing, and output a 14-bit deep super RAW file, significantly improving the signal-to-noise ratio and dynamic range.
Vivo Optical System, the "Optical Giant" in the field of moving image
Vivo has a deep cooperative relationship with ZEISS, so that all vivo X80 lenses have reached the ZEISS T* coating standard to ensure that vivo's imaging standards are met in terms of white balance, color accuracy, anti-glare and resolution.
In terms of sensors, the vivo X80 Pro is equipped with an exclusive customized GNV ultra-large bottom sensor, and the X80 is the first Sony IMX866 RGBW outsole sensor. Behind the sensor models, there are many unknown innovations. For example, GNV, through customized filters, Vivo once again broke through the limits of GN1 and adopted a high-specification lens combination of 1G +6P, as well as the coating process of the top grid. It can be said that the lens modules equipped with the vivo X80 series are all customized.
Vivo X80 Pro takes samples of night scenes
Friends who like to take pictures know that night shooting is a very extreme scene in photography, the light is dark to bring great difficulty to shooting, sometimes encounter small animals, open the flash to shoot small animals have long been frightened and disappeared. Vivo X80 series of low-light mobile phone "night vision" in a non-disturbing way to record everything in front of the eyes, the ultimate capture of light also ensures the clarity and purity of the picture. Yi", do not disturb the dreams of late at night.

Many industry media and head KOLs are very recognized by the strong image strength of the vivo X80 series, and they are even more surprised by the "night vision" function of the low-light mobile phone, giving high praise such as "taking a good night scene", "the best camera phone", "walking night vision" and so on. Users are also satisfied with the image performance of the X80 series, "vivo brand night vision", "talk about night scenes in front of vivo, others are brothers" and other evaluations.
Vivo with continuous black technology for users to surprise users again and again, if you have a persistent pursuit of imaging, then vivo X80 series will be a good choice.
