As the mobile phone market enters the era of quantitative competition, major manufacturers have chosen to enter the high-end market. Among them, the creation of professional imaging capabilities is the top priority for forming technical barriers and occupying the high ground of reputation.
The ultimate hardware stacking, pursuing larger sensors and more cameras, and squeezing optical performance to the limit from physical principles, has made the boundary between image flagships and professional cameras increasingly blurred. Now we can even see that mainstream flagships such as the vivo X90 series released at the end of the year have popularized one-inch large-sole main cameras, thus achieving a shallower blurred depth of field and better dark light performance.
But how to go further? If you want to achieve better filming and photography experience, you cannot exert the full strength of optical originals without the support of powerful computing power. To this end, major mobile phone manufacturers have begun to deepen the potential of computing photography, and self-developed imaging chips represented by plug-in ISPs have become the first choice in the key field of Zhulu computing photography. Among them, the V2 chips equipped with the entire series of vivo X90 series can be called "the strongest self-developed core in China." With the support of the powerful computing power of V2 chips, the X90 series has achieved dual bursts of image performance, with the goal directly targeting the "king of mobile images".
empowers ISP with AI accelerator, and improves computing and photography capabilities leapfrog
vivo has created a plug-in chip technology form, and uses high-energy-efficient and low-latency self-developed chips in the fields of performance and display. Judging from the technical principles and industry trends, computing photography represented by ISP has become the next breakthrough in the mobile phone industry. As a "new force in China's self-developed chip ", vivo has always been at the forefront of self-developed ISPs from V1, V1+ to V2, from X70 to X90.
V1 chip brings the throughput capability of flagship desktop computers to the vivo X70 series, unlocking the era of hardware-level algorithms for mobile imaging; while V1+ has both image and performance attributes, achieving one core and two uses. This time, the vivo X90 series will be equipped with the entire series with a newly upgraded self-developed chip V2, reconstructing the chip architecture, greatly improving computing power, giving the X90 series more powerful image processing capabilities, and having excellent image performance in various complex light source environments, effectively expanding the space for mobile image creation.
It is understood that this intergenerational upgrade of V2 is not a minor repair, but a leapfrog improvement in the body layer architecture. It has upgraded from a traditional ISP architecture to an AI-ISP architecture, empowering the ISP chip with an AI accelerator, and rebuilt three major sections: on-chip memory unit, AI computing unit and image processing unit.
In order to allow users to shoot videos with clearer details, more natural colors and better texture, vivo also wrote up to 19 "Ace Image Algorithm" into the chip core, and newly upgraded AI-NR noise reduction, HDR tone fusion, MEMC frame insertion and other algorithms to comprehensively enhance the image and display effects. The writing of these capabilities also allowed V2 to break the ceiling of ISP algorithm effects again and push vivo mobile imaging technology to a new level.
new image experience: 4K super-sensory "night vision device", Zhencai night view video
With the support of self-developed chip V2, the vivo X90 series brings more video shooting capabilities based on computing photography - including 4K super-sensory "night vision device" and Zhencai night view video. Both effectively reduce the difficulty of shooting and bring a richer and more interesting image experience.
self-developed chip V2 can help vivo X90 series greatly improve the brightness and clarity of night scene photography, shorten the shutter speed, reduce motion drag, integrate and cure image algorithms, strengthen motion anti-shake, bring extreme night images and night scene motion recording functions, and transform the mobile phone into a 4K super-sensing "night vision device". In an environment close to pure black (the ambient illuminance is less than 1lux), the vivo X90 series can still capture light, reduce noise, and obtain a picture full of detailed and colorful.
is based on the "one-inch large bottom" sensor and aperture to improve the photosensitive ability. Combined with the RAW domain video noise reduction algorithm and the super computing power of the V2 chip, the vivo X90 series achieves the ultimate extreme night video shooting ability, allowing 4K video shooting experience to be silky and smooth, and the video quality and brightness are greatly improved. Users can even take pictures of star points in the sky under the dim lights of camping.
In order to better deal with scenes with complex light rays such as neon streets and concert scenes at night, vivo X90 Pro+ perfectly combines the self-developed chip V2 with Zeiss one-inch T* main camera, optimizes backlight and improves noise reduction, and uses HDR function to combine imaging algorithms to effectively support the recording effects of the X90 series in the daytime light ratio and conventional night scene environment, bringing high dynamic picture quality Zhencai night scene video.
In addition to self-developed chip V2, the vivo X90 series also brings a richer computing photography experience through self-developed algorithms and Zeiss' joint research and development algorithms.
It can be said that it is precisely because vivo has unswervingly deepened its efforts in the fields of self-developed chips and imaging algorithms that the X90 series is full of confidence in the process of striving to "be the king of mobile images". As Hu Baishan, executive vice president and chief operating officer of vivo, said: "The efficiency of competing with parameters is getting lower and lower. The underlying technological innovation determines future competition. Doing the underlying layer well can minimize the dependence on hardware."
believes that as vivo technology accumulates more and more profound, the future mobile imaging achievements of X series will still be full of imagination, which will surely bring more surprises to global consumers.
